 very plain ; femora and coxie dark, bases and apices of femora, and rest of legs yellow ; 

 abdomen very finely reticulately lineolated, about twice as long as the head and 

 thorax combined. Length including ovipositor about 2 mm. 



$. — Very similar to the 9 but the abdomen only as long as the head and 

 thorax together. Length about I mm. 



Locality. — Bred from Diplosis sorghicola, collected at Baton Rouge, 

 La. (Webster No. 3630). . ■ 



Type. — No. 10929, U. S. National Museum.

Superfamily ICHNEUMONOIDEA. 



Urosigalphus bruchi, new species. 



9. — Black, head and thorax rather finely rugoso-punctate ; antennal grooves 

 deep, reaching to vertex ; antennse 14-jointed, reddish, reaching to metathorax ; 

 median area of mesothorax coarsely rugose, lateral areas shiny, finely sparsely punc- 

 tured ; scutellum strongly elevated, viewed laterally its outline sharply angulated ; 

 median carina of metathorax ending in a sharp, short projection ; scutellum, post- 

 scutellum and base of metathorax rugose; truncation sparsely rugoso-punctate; hind 

 coxL-e large ; hind femora robust, their tarsi dusky ; wings dusky, nervures light, 

 stigma large, dark ; longitudinal striae on abdomen distinct for about two thirds the 

 length of the abdomen ; ovipositor about one third the length of abdomen ; apex of 

 abdomen produced to two short spines. Length 3.75-4 mm. 



^. — Similar, antennas reaching one third distance to apex of abdomen; 

 abdomen at apex only indistinctly spined. Length 3.75 mm. 



Locality. — Victoria, Texas, bred from Bruchiis in Prosopis. 



Type. — No. 10047, U. S. National Museum. 



This species is the size of anthoiiomi but is easily distinguished by 

 the absence of the pyramidal area between the ocelli and by the 

 sharply elevated and angulated scutellum (in anthonomi the scutellum 

 seen in profile is rounded above). 



Superfamily APOIDEA. 

 Neolarra congregatus, new species. 



9. — Head and thorax black, coarsely, deeply and closely punctured, closely 

 covered with scale-like pubescence almost concealing the surface, grayish above 

 white on pleura; ; facial quadrangle broader than long ; punctures on clypeus smaller, 

 mandibles reddish apically ; flagellum dull reddish beneath ; tegulre large, black, 

 punctured all over ; legs dark, knees and tibiae apically, somewhat reddish ; abdomen 

 with segments 1-4 red, apical segments darker, all closely coarsely and deeply punc- 

 tured ; segments 1-5 with bands of white appressed pubescence on the apical margins ;
