Eggs.—Oblong, covered with hexagonal depressions and bright green in color. Length 0.6 mil.; width 0.3 mil. Duration of egg stage 12 days.

Young Larva.—Length 2 mil.; head twice as wide as the body, round and deep ochre yellow; body dull yellowish green with a faint paler stigmatal stripe.

Mature Larva.—Body of uniform thickness, deep green with a narrow sub-dorsal and stigmatal white stripe, and a dorsal greenish-white hair line; dorsal space pale green; ventral space yellowish green. Head brownish green with a lateral white stripe which is a continuation of the sub-dorsal stripe of the body. Length at rest 25 to 26 mil.; when crawling, 26 to 27 mil. Food plant, Pinus strobus. Duration of larva stage, 35 to 40 days. Described from 57 specimens.

Prof. Westwood, in his Generic Synopsis, characterizes this genus as follows: “Antennæ 13-jointed, clavate, third and fourth joints minute; club ovate; thorax long-ovate; collar moderate; thorax depressed in the middle; abdomen long-ovate; ovipositor exserted, wings with stigmal branch distant from the union of the subcostal nerve and the costa.”

In view of the recent controversy between Prof. Riley and Mr. Howard, in regard to this genus and the genus Antigaster of Wa1sh, I deem it advisable to publish the above from Westwood, verbatim etliteratum. Just beginning my entomological studies, I do not pretend to take issue with either of these gentlemen, but merely desire to draw their attention to the ovipositor in this genus, which both seem to have entirely overlooked, and which, according to above description, is exserted.

Hadena idonea, n. s.

♂ ♀. This species is similar in size to verbascoides and cariosa; it is very like the latter only instead of reddish brown the color is of an ochrey brown, rather pale, the stigmata concolorous, rather wide, illdefined, separated by the dark median shade. The claviform spot is open, and stretches across the median field nearly touching the even t. p. line. Lines geminate, marked on costa. A slight, irregular basal streak and one below it on internal margin. Terminal field dark shaded, obtaining twice, opposite cell and at internal angle. Fringes dark cut with pale. Hind wings very dark, with paler fringes, concolorous, an indication of discal mark; beneath with faint double extra-mesial lines; the narrow terminal space paler on both wings. The costa of fore wings is more or less pale. Abdomen tufted. This species is more ochrey than vulgaris. Texas, Kansas, Wisconsin.
