E. nigriccps Sin. could not be inserted in the table from the 

 description. Its habitat is given by Smith (New Species of 

 Hymenoptera in the Britisli Museum, 1879, p. 103) as Texas 

 and California. It is apparently near to E. rcniigatns. 



Epeolus concavus Cress. (Fig. i.) 



In the female of this species the apex of the abdomen pre- 

 sents characters resembling those of penidlliferus but quite 

 different from those of any other species we have seen. The 



Efieolus concavus Cress. Apex of abdomen ?. 



fifth dorsal segment is almost squarely truncate behind. This 

 appearance is partly produced by a dense brush of silvery or 

 golden tipped, dark hairs, all of which terminate together to 

 form a flat surface. The concave ventral plate is also peculiar 

 to these two species. 



The male greatly resembles rcmigatns but differs in having 

 the sixth segment black, without a pale apical band. 



Epeolus penicilliferus sp. nov. Female. Length 15 mm. Large and 

 stout ; black. Face, clypeus, vertex and posterior margin of head above 

 covered with light ochraceous pubescence, lightest below on the clypeus. 

 Broad posterior margin of prothorax ; posterior margin of inesothorax, 

 extending forward along the sides nearly to tegulas ; two very distinct 

 oval bands on anterior middle ; large spot on pleura covering tubercles ; 

 middle of anterior border of scutellum ; posterior margin ; post-scutellum 

 and two oval spots on metathorax, covered by dense appressed light buff 

 pubescence. Four posterior coxse with a silvery spot externally. Ab. 

 domen broad, oval. Fiist segment with its basal half, except basal black 

 spot, and rather wide posterior and wide lateral margins, light buff. The 

 central black band nearly four times as long as wide, its edges parallel, 

 the ends obliquely truncate. Second, third and fourth segments with 

 broad posterior bands growing lighter posteriorly. The one on the sec- 

 ond confluent with a large nearly quadrate lateral spot of same color.
