150 HYMENOPTERA. 



however, I can see no reason for this separation, as there 

 are no characters to indicate a radical difference ; in fact 

 both sexes so strongly resemble P. inodestus that it is quite 

 probable they are this species. At least they cannot be 

 definitety determined without an examination of the male 

 genitalia. 



Prosopis confliiens Sm. 1853. 

 1853. P. confluens, (female), Sm. Cat. Hym. Brit. Mus. 1:24. 



Only a very brief general description is given of the female 

 of this species, from which it is unrecognizable. 



Prosopis sufTusa Ckll. 1896. 

 1896. P. suffusa, (male), Ckll. Psyche Supp. 7:32. 



From the description this is evidently one of the " Asininus 

 Division", probably P. wootoni, or very nearly related to it. 



Prosopis g-eorgfica Ckll. 1896. 

 1896. P. ^^or^/fa, (male), Ckll. Psyche. 7:438. 



This is characterized by its, "small size, converging orbits, 

 yellow face, and largely yellow scape ". The lateral marks 

 terminate, "broadly on orbital margin" ; abdomen impunc- 

 tate. I have been unable to recognize this. 



Prosopis rugosiilus Ckll. 1896. 

 1896. P. rugosulus, (male), Ckll. Psyche Supp. 7:28. 



The punctured abdomen of this species would indicate a 

 relationship with episcopalis, as would also the face marks 

 with, "lateral extensions — ending, about on level with mid- 

 dle of scape in a broad truncation". I have the lot from 

 which this was described, but can find only episcopalis in it. 

 Dr. Howard writes that this species is known in the National 

 Museum only by its unique type, and I know of no other 

 specimen. 



Prosopis verticalis Cr. 1869. 

 1869. P. verticalis, (male), Cr. Proc. Bos. Soc. Nat. Hist. 12:271. 



1909. P. verticalis, (female), Lov. Ent. News. 20; 413. 



1910. P. verticalis, Lov. Psyche. 17 : 184. 



Apparently this is related to P. rudbeckice , and may be the 

 same species. " The stripe on each side of face curves in- 

 wardly just above the insertion of antennae, and ends in a
