218 AMERICAN HYMENOPTERA. 



9- — 7 mm. — HeMfl. — With the anterioi- aspect finely sculptured, dull; clypeus 

 rather shining and distinctly closely punctured ; cheeks shining, minutely sculptured 

 and about half as wide as on eye, the eye about as wide as the space between the eyes at 

 base of clypeus ; malar space nearly as high as the pedicel is long : ocelli forming a tri- 

 angle, the anterior ocellus about as far from the posterior ocellus as a posterior ocellus 

 is from the nearest eye margin, the .space between the posterior ocelli about one and one- 

 half times as great as distance between the lateral and anterior ocelli ; antennse twenty- 

 nine jointed, the first joint of the flagellum about as long as the scape and pedicellum 

 together ; almost entirely black, only the scape, pedicellum and mandibles partly pale, 

 the former two chiefly yellowish and brown, the latter yellow, brown at apex ; 

 pubescence silvery, densest on the face, where in certain lights it rather obscures the 

 sculpture. 



Thorax — Dorsuluni sculptured much like the face, not so conspicuously clothed 

 with pubescence, tlie pubescence very short and somewhat tinted with yellowisli ; 

 pleura chiefly with rather distinct adjoining punctures on a quite shining sur- 

 face; basal area forming a trapezoid about twice as wide at base as at apex, the 

 basal transverse carina being about one-half the length of this area, areola con- 

 fluent with the petiolarea. from the carina separating the external from the ex- 

 ternal median area to the basal transverse carina, the areola is almost an equi- 

 lateral triangle, region of the petiolarea impressed and transversely rugulose, 

 petiolarea partly confluent with the internal area, the internal area wrinkled, 

 shining and separated from the angular area, which is conspicuous and almost 

 a triangle, external median area more coarsely sculptured than the external area, 

 from which it is separated by downward arched carina, spiracnlar area and mid- 

 dle pleural areas confluent, the spiracle almost adjoining the pleural carina and 

 united therewith by a broad elevation of the tegument, excepting its append- 

 ages, the thorax is black; wings hyaline, the nervures brown, rather brownish 

 testaceous, the stigma testaceous, tinted with brown, wing nervures at base of 

 wing and tegulse yellow, areolet a trapezium, petiolate or subpetiolate, the petiole 

 almost wanting, not more than half the length of the shortest side of the areolet, 

 anterior and middle coxa? yellow and brown, posterior coxae black, with reddish 

 on the apical half, all trochanters yellow, except the proximal pair of posterior 

 legs, which are brown, all femora ferruginous, anterior and middle tibiae testaceo- 

 ferruginous beneath, yellowish above, posterior tibiae brown above, ferruginous 

 beneath, yellowish above, posterior tibiae brown above, ferruginous beneath, tarsi 

 more or less brown, pale at base, tibial spurs testac^eous. 



Abdomen. — Ferruginous, petiole black, as is the second segment, excepting an 

 illdefined subapical hand of ferruginous, greater part of basal half of the third 

 segment black, fourth segment partly blackish at base, venter chiefly yellow ; 

 ovipositor enveloped by the black sheaths, the protruding portion about as long 

 as the petiole. 



Type. — University of Kansas. 



Type locality. — Galveston, Texas. 



One specimen collected in May (F. H. Snow). 



Ainorphota coiifluens mutation a. 



Like conjiuens, this is related to Lwinerium f hostilis, distinctus 

 and affinii, but structurally distinct from each.
