Psorophora ciliata, Fabr., is the only species of the genus Psorophora known to occur in the United States. It is a widespread species and is known to the writer to occur in Massachusetts, New Jersey, Pennsylvania, District of Columbia, Vilginia, Kentucky, Illinois, Florida, Louisiana, Arkansas, Nebraska, Texas and California. It is, however, rare in its northern range and seems to be a lower austral form. It may have a tropical range, but among many mosquitoes received by the writer during the past year from Mexico, Nicaragua and Cuba, this species does not occur. In his “Notes on the Mosquitoes of the United States” (Bulletin 25, New Series, Division of Entomology, U. S. Department of Agriculture), published August 23rd, 1900, the writer calls attention to the fact that Psorophora and Megarhinus have not been studied by investigators engaged in working upon the transfer of Haematamoebæ by mosquitoes, and urges that physicians and bacteriologists in our Southern States pay some attention to the mosquitoes of these genera.

Neophasia Terlootii was described a great many years ago, and the description being in Latin, it is not surprising that Dr. strecker overlooked it in the hurry to publish his description of the female I sent him, which he supposed had not been previously described. It is a little surprising, however, that Dr. Skinner, who had the first opportunity to examine one of my examples of Terlootii, should have failed to recognize the generic characters of the insect until Dr. Strecker's description as Neophasia epyaxa was published.

In the course of my already-published studies, the probabilities as to the homology of the last anal vein of the Papilionides primary have varied. From preparations of the pupal wing of the Hesperiades, it has become clear that the fork to second anal at base is the remains of the third anal vein, which is irregular and more extended in the fore wing of the chrysalis and does not attain the outer margin. It is furcate aud connected with the second anal in the pupal stage. On the other hand, the downwardly curved, short, last and free anal vein of the Papilionid primary cannot be homologous with this, as, indeed, I originally contended. This vein reaches the internai margin, and is probably a survival of the fourth anal.

Pulvinaria Tinsleyi, n. sp.

Shriveled adult female scales on the twigs, light brown, elliptical, convex. Ovisac, clear white, texture as in P. innumerabilis. After boiling in K. O. H., derm colourless, not pitted or tessellate. Legs and anal plates tinged with yellow. Spines of lateral cleft in threes, one long and curved; 76 μ long, two quite short, 28 μ long. Margin with one row of stout blunt spines 40 μ long, 6 broad. Anal plates heart shaped, each 100 μ broad and 136 μ long, Antennæ 7-jointed, width quite constant, but the length of the joints seems to be quite variable. I have examined ten, with the following results in μ: Joint (1) 24 to 40, (2) 40–60, (3) 68–80, (4) 52–64, (5) 28–36, (6) 28–40, (7) 44–52. Formula 3472651. Joint 3 is always longest, while 4 is nearly as long, but never equal; 1 is always the shortest, 5 and 6 are next and sometimes nearly equal. Joints 2 and 3 have two long hairs each; 5 and 6 have 3 each; 7 seems to have 9, the terminal one very long.

Bombomelecta larreœ, n. sp.

♀.—Length 12½ mm.; general build and structure of B. thoracica, but the scutellum is convex with a central depression, and wholly without spines; while the claws have the inner division short and broadly truncate. The maxillary palpi are 6-jointed, and the mandibles have a strong tooth on the inner side. Black; pubescence of the face and vertex pale brown; of the occiput, labrum and clypeus, black; of the pleura, metathorax and scutellum, black; of the post-scurtellum, yellowish, especially noticeable at the sides; of the mesothorax, orange-fulvous, short, dense and conspicuous in front, thin behind. Abdomen with broad but inconspicuous ochreous bands on segments 2 to 4, more or less interrupted in the middle on 2 and 4, represented on the first segment by lateral patches, and a few ochreous hairs even in the middle; fifth segment with black hairs. Antennæ entirely black, apex truncate, the corners of the truncation rounded. Legs black, with black pubescence; spurs black, hind spur of hind tibia larger than the other, and somewhat bent. Wings dark fuliginous, with hyaline patches on the third transverso-cubital and second recurrent nervures; venation resembling that of B. thoracica, var. fulvida, except that the first recurrent nervure joins the second submarginal cell almost at its apex.

Euptoieta claudia, Cram.—This species had never even been observed in previous years, but this season appeared plentifully at Bird's Hill in June, and again in August (16th) and September (4th); it was also met with at St. James, just outside the city limits. The species is usually common in prairie districts farther west.

Melitœa Harrisii, Scud.—Taken at Bird's Hill on July 1st, 1899. This season I came across a larva in the act of pupating, but missed the butterflies.

On the 18th June, 1900, Mr. C. T. Hills, of Chicago, was kind enough to send me a batch of about 79 eggs of Arctia phalerata, Harr. The parent moth was captured on the 12th June, and enclosed in a box over night; on the next day, the 13th, the eggs were laid.

Egg.—.75 mm. in width, semi-ovoid, about as high as wide, shiny, smooth, creamy-white, concave at base.

The eggs hatched on the 20th and 21st of June. Duration of egg stage 7 or 8 days.
