TWO GENERA OF CHALCID-FLIES — GAHAN 367 



ceous; face somewhat lighter testaceous than rest of liead; apices of 

 mandibles dark brown; palpi f uscotestaceous ; vestiture of head white, 

 the hairs along inner orbits longer than on remainder of head, posterior 

 orbits with a dense border of short silvery-white pile along eye margin. 

 Pronotum dorsally, mesoscutum except lateral margins, axillae, most 

 of mesopleura, mesosterniim, propodeum, and posterior coxae dorsally 

 blackish with a more or less strong aeneous tinge ; prothorax beneath, 

 prepectus, narrow lateral margin of mesoscutum, tegulae, scutellum, 

 mesopleuron posteriorly, anterior and intermediate coxae, and tro- 

 chanters dark testaceous; all femora and tibiae fuscotestaceous, the 

 posterior tibiae with a moderately broad, white, posterior margin; 

 anterior tarsi fuscous ; intermediate tarsi, except apical segment, white ; 

 posterior tarsus with dorsal margin of basitarsus and all of second, 

 third, and fourth segments white; basitarsus beneath and apical seg- 

 ment black. Forewing dark fuscous from beginning of curve in sub- 

 marginal vein to apex of stigmal vein, subhyaline basally and apically ; 

 posterior wing hyaline ; abdomen brownish black with weak aeneous 

 reflections ; ovipositor uniformly testaceous. 



Head viewed from in front very slightly higher than broad, slightly 

 narrower below^ than above; eyes convergent; frons at its narrowest 

 point about equal to one-third the greatest width of head ; scrobicular 

 depression shallow, poorly delimited ; ocelli in a distinctly obtuse tri- 

 fingle, the lateral ones a little less than their own diameter from the eye 

 margins and fully three times their own diameter in front of the oc- 

 cipital margin. "Whole head finely sculptured and subopaque. An- 

 tennae inserted below eyes, 13-jointed, weakly clavate; scape sub- 

 cylindrical, slightly curved, not attaining level of anterior ocellus; 

 pedicel approximately twice as long as broad; ring joint subquadrate; 

 first funicular segment about three times as long as broad, seventh 

 segment subquadrate; club slightly thicker than funicle, indistinctly 

 3- jointed, obliquely truncate. 



Prothorax short, conical, finely sculptured dorsally; mesoscutum 

 very slightly longer than broad; prescutum and scapulae very finely 

 punctate, the posterior median portion of mesoscutum weakly sculp- 

 tured and not deeply concave, the scapulae apparently very slightly 

 compressed at their posterior ends (the mesoscutum somewhat dis- 

 torted) ; scutellum strongly convex, ovate, nearly twice as long as 

 broad, very finely and uniformly sculptured, dull, with a tuft of coarse 

 black bristles medially; axillae sculptured like prescutum, separated 

 by a distance somewhat less than the width of base of an axilla ; pro- 

 podeum deeply semicircularly emarginate, transversely linear medi- 

 ally, the lateral lobes subtriangular and weakly sculptured around the 

 spiracle and apically but polished medially and with the apical one- 

 third pilose ; prepectus and tegula finely sculptured, dull ; mesopleuron
