nearly black; dorsulum with a brownish yellow V on each side, one side of 

 which adjoins the anterior lateral margin of the segment, the other outlines the 

 position of the obsolete parapsidal groove, propleura with a yellowish line along 

 the upper edge, mesopleura with a broad brownish band beneath the shallow 

 impression which it follows; venter of abdomen yellowish, the dorsal segments 

 beyond the second with a brown apical margin black at base ; legs yellowish 

 brown, posterior cox^ blackish at base, posterior femora chestnut brown, the 

 tibife of posterior legs blackish at base and apex, the tarsi of posterior legs in- 

 fuscated.

Thersilochus egregiacolor, n. sp. 



Superficially like facilis. 



Female. — Length, 9 mm. : ovipositor exeerted, 7 mm. Head shining, closely, 

 distinctly punctured; clypeus with sparse, distinct punctures; cheeks rather in- 

 distinctly, minutely punctured; antennae thirty-nine jointed. Dorsulum with 

 almost contiguous distinct punctures, shining, parapsidal groove represented by 

 very shallow broad impressions on the anterior half of the dorsulum; scutellum 

 shining, closely punctured ; basal area of metanotum an acute-angled triangle, 

 areola pentagonal, nearly twice as long a broad, the sides angled above the mid- 

 dle, the surface of the areola shining, rather sparsely punctured, petiolarea 

 transversely striate, rugose at base, dullish, lateral areas and metapleura sculp- 

 tured nearly like the dorsulum, the apical lateral area rugulose ; mesopleura be- 

 neath and anterior to the oblique depression punctured nearly like the dorsulum, 

 the oblique depression partly finely striate, partly smooth and polished, above 

 the impression the tegument is smooth, shining and minutely, sparsely punc- 

 tured; wings hyaline, stigma and nervures dark brown, transverse median ner- 

 vure slightly basad of interstitial, recurrent nervure almost exactly insterstitial, 

 abcissa of cuLitus beyond the transverse cubitus about one-third as long as the 

 transverse cubitus, first abcissa of the radius about one and one-half times the 

 length of the transverse cubitus, second abcissa of the discoidal nervure half the 

 length of the recurrent nervure, terminal abcissa of the cubitus, excepting the 

 stump of a vein and terminal abcissa of the subdiscoidal cell, entirely hyaline. 

 First abdominal segment shining, partly smooth, partly delicately striate; second 

 segment dullish, delicately striate; succeeding segments minutely granural, 

 subtle and minutely, sparsely punctured as in the other species of the genus. 

 Pubescent as usual in the genus. Ferruginous; orbital line, malar space, cly- 

 peus anteriorly, mandibles except apex, and tegulte yellow; basal joint of scape 

 brown, remainder of antenna? dark brown, almost black; anterior and middle 

 coxae and trochanters with some yellow, a narrow stripe on anterior femora and 

 tibi:e and on middle tibia? yellowish, coxa? and trochanters of anterior and middle 

 legs black in part, the posterior trochanters with some yellow, posterior tibia? 

 brown with a whitish stripe on the outer side, tarsi brown, except the first three 

 joints of the anterior tarsi, which are rather pale brownish; metanotum at base, 

 mandibles at apex, first and second dorsal abdominal segments almost entirely, 

 and base of third dorsal abdominal segment black, a dark brown spot at base of 

 succeeding segments; ovipositor chestnut brown, sheaths black.
