TWO GENERA OF CHALCID-FLIES^ — GAHAX 349 



the cilia are whitish; posterior wing hyaline; legs uniformly yel- 

 lowish testaceous; ovipositor yellow. 



Head, viewed from in front, as long as broad, rounded above, nar- 

 rower below; cheeks slightly rounded, nearly straight; eyes rather 

 large, slighth' converging toward vertex, s^^arsely pilose ; f rons equal 

 in width to a little more than one-third wndth of head; scrobe shallow, 

 immargined, extending approximately half the distance between an- 

 tennal fossae and anterior ocellus; ventral margin of frons lateracl 

 of antenna! fossa more or less abruptly truncate and forming an 

 oblique ridge extending from ventral margin of eye to base of antenna ; 

 malar groove complete but very fine and obscured by sculpture ; ocelli 

 in an obtuse triangle; ocellocular line equal to diameter of a lateral 

 ocellus; entire head Avith nearly uniform, fine, shallow, reticulate- 

 punctate sculptui-e; lateral margins of frons clothed with long whitish 

 hairs ; vertex and middle of frons with much shorter and sparser hairs ; 

 head, in dorsal view, thin anteroposteriorly ; occiput slightly concave 

 and forming with vertex a sharply abrupt angle. Antenna slender, 

 weakly clavate: scape not quite attaining front ocellus, cylindrical; 

 pedicel about two and one-half times as long as broad ; ring joint twice 

 as broad as long; first funicular segment a little shorter than pedicel, 

 fully twice as long as thick; second nnd third segments each about 

 equal in length to first; following funicular segments successively de- 

 creasing in length, the seventh subquadrate; club obliquely truncate, 

 nearlj'^ as long as the three preceding funicular segments. 



Thoi-ax, when in natural position, approximately twice as long as 

 broad; prothorax conical, short; mesoscutum a little longer than 

 broad; parapsidal grooves deep and broad; prescutum with fine, shal- 

 low, reticulate-punctate sculpture ; scapulae and the depressed medio- 

 posterior portion of mesoscutum very weakly sculptured; whole 

 mesoscutum sparsely clothed with very short, inconspicuous hairs; 

 scutellum finely sculptured, opaque, with about 30 black bristles of 

 varying lengths scattered over the disk; axillae sculptured like scutel- 

 lum, each with several short black bristles; propodeum deeply emargi- 

 nate, almost reduced to a transverse line medially, the lateral lobes 

 jiractically smooth; propodeal spiracles conspicuous and nearly 

 circular. 



Forewing vei-y nearly thrice as long as broad; marginal vein about 

 three times as long as stigmal vein ; postmarginal vein a little longer 

 than stigmal: costal cell in lai"ge })art bare but with some weak cilia 

 on the basal one-third and with api'^al area in front of the curved 

 portion of submarginal vein densely clothed with coarse blackish 

 cilia ; area behind the straight ])ortion of submarginal vein mostly 

 bare but with a few irregularly placed cilia in the proximal angle and 

 extending in a narrow streak a short distance distad near the posterior
