318 HYMEXOPTERA OF AMERICA. [PART I. 



the margin being quite a high crest. In 0. conformis it is only 

 slightly reflexed and a little canaliculated, but not making a sharp 

 deep channel as in 0. Bravo. The tubercle of the head of the 

 males is also very characteristic. (We notice that such are found 

 in other species with strong canaliculate 2d segment as Ancistro- 

 cerus tuberculiceps.)

 valleys of the Sierra Madre and near Mextitlan.

 bordered by sharp edges, nor with well-defined limits. Abdomen

1 There can be no doubt, whatever, about the identity of this species 

 with 0. oculatus J , it being very well described by Say. He called it 

 anormis, because it has not the form of Eumenes, and he only classed it in 

 this cenus because of the similar structure, of its mouth, being unaware 

 that these two genera are not to be separately distinguished by the mouth. 

 And further he says (Bost. Journ.), "It is like the Oculatus Say." Be>ides, 

 he took his female specimen for a male, which made him find some differ- 

 ence from Oculatus, which was described from a male. 



2 In some copies the antennae have been painted all yellow, by mistake. 

 The yellow color is only to be seen beneath when developed under the 

 dagellum.
