For many years an insect, familiarly known among farmers as “the wire-worm,” has committed ravages from time to time among the wheat crops in different parts of the Province. As the history of this insect has not hitherto been traded out, I am happy to be able to make public, through the pages of the Canadian Entomologist, the following description of its larval and pupal states.

The species of this genus bear some resemblance-especially the smaller species-to Lithocolletis: but they may be distinguished by the attitude in repose in most species, and by the developed maxillary palpi in all. They usually sit (especially the larger species, for I have not observed it in some of the smaller ones), with the anterior part of the body elevated upon the anterior and middle legs, whilst the posterior legs are applied to the sides of the abdomen, the apex of which touches the surface upon which they rest. In some of the smaller species, the maxillary palpi are small, and sometimes almost concealed by the labial palpi. This is the case in Gracillaria robiniella (Parectopa robiniella Clemens), and G. lespedezæfoliella (P. lespedezæfoliella Clem.), upon which Dr. Clemens erected the genus Parectopa, as not having any visible maxillary palpi.

During my recent trip through Colorado and adjacent territory, as a member of the New York agricultural editorial excursion party, I made it a point to collect whenever an opportunity was offered. Through Kansas, the three-minute stops at the stations. many of which are out on the open plains, afforded me opportunity for turning over old railroad ties, &c., for beating the herbage and rank vegetation at the sides of the track, or for searching in the dry grass and weeds for Orthoptera.

Cone of the vertex smooth on the margins, apex mucronate. Mesosernum bidentate. Green: labrum, clypeuss and underside of the cone yellow.

Male and, Female. Cone of the vertex standing obliquely forward, apex mucrornate, the minute spine slightly deflexed, especially in the female; the sides parallel from the base a little above the first joint of the antennæ, where they are slightly angulate; not serrated or granulated on the margins; front side has, near the base, a prominent tubercle; there is also a tubercle below this between the antennæ
