emarginate ; apical portion of venter with three light bands,

a suggest IN. verecunda, which, however, is a different

Nomada neomexicana, sp. n. (vel texana, subsp. ?). 
? .—Length about 8 millim.

tegule orange-ferruginous; light markings pale lemon- 
yellow (considerably lighter than in N. modesta) ; ventral
