DESCRIPTIONS OF NEW SPECIES AND VARIETIES. 65 



I. P. Trimble, of New Jersey, and 1 2 subsequently received from the same gentleman- 

 all obtained from larvie of Conotrachelus nenuphar. 



As I am informed by Mr. E. T. Cresson, of Philadelphia, who pays especial atten- 

 tion to the classification of the Ichnettmonidce, it might more properly be referred to 

 Holmgren's genus Thersilochiis, which differs from I'orizon in the greater distance be- 

 tween the antenna? at base, and in the venation of the wing. [Third Kept., p. 28, 

 Fig. 9.

 antenna? longer than head and thorax, slender, black; thorax closely and minutely 

 punctured; mesothorax with a deeply impressed line on each side anteriorly; scutel- 

 lura convex, clos'ely punctured, deeply excavated at base; inetathorax coarsely sculp- 

 tured, truncate and excavated behind, the elevated lines sharply defined, forming an 

 irregularly shaped central area, and a triangular one on each side of it, the outer posterior 

 angle of which is prominent and subacute ; wings hyaline, iridescent, uervnres black- 

 ish, stigma large, areolet incomplete, the outer nervure wanting; legs pale honey- 

 yellow, coxte paler, tips of posterior femora, and their tibia-, and tarsi entirely black- 

 ish ; abdomen elongate ovate, flattened, petiolated, the first segment flat, gradually

 two following segments opaque, indistinctly sculptured ; remaining segments smooth

 0.50 [inch=!2.5 mm ]. Ferruginous, opaque. Head transverse, rather broader than 

 thorax, the front much depressed ; face prominent centrally beneath antenna?, closely 

 punctured, thinly clothed with pale pubescence; clypeus and cheeks shining; tips of 

 mandibles black ; antenna?, long, slender, filiform, ferruginous, blackish at tips ; thorax 

 rugose; scutellum prominent, with sharp lateral margins ; inetathorax prominent, quad- 

 rate, abrupt laterally and posteriorly, finely reticulated and pubescent, the upper 

 posterior angles produced on each side into a long, divergent, flattened, subacute 

 spine; disk with two longitudinal carina 1 , from which diverges a central transverse 

 carina; tegula' piceous; wings hyaline, subiridescent; a narrow, dark fuliginous band 

 crosses the anterior pair a little before the middle, and a broad band of same color be- 

 tween middle and apex, this band having a median transverse hyaline streak ; areolet 

 wanting, second recurrent nervure straight, slightly oblique ; apex of posterior wing 

 fuscous; legs long and slender, ferruginous, more or less varied with fuscous; pos. 

 terior coxa--, tips of their femora, and their tibiae and tarsi, fuscous; base of foul 

 posterior tibia? more or less whitish, forming a rather broad annulus on posterior pair ; 

 abdomen petiolated, subconvex, densely and finely sculptured, blackish, baeal segment 

 tinged with reddish, the second and third segments distinctly margined at tip witlj
