HYMENOPTERA 607 



Fam. EUMENIDAE. 

 PsEUDOPTEROCHEiLUS Perkins. 



Pseudopterocheilus Perkins, Ent. Mo. Mag. xxxvii. p. 266. 

 To this genus belong the following species. 



Pseudopterocheilus pte7'ocheiloides, P. 

 Odynerus pterocheiloides P., huj. op. i. p. 6g. 



Pseudopterocheilus congruus, Sm. 

 Odynerus congruus Smith, huj. op. i. p. 69. 



Pseudopterocheilus relicttis P. 



Pseudopterocheilus relictiis P., Proc. Hawaii Ent. Soc. i. p. 63 ; not Odynerus 

 relicttis P., huj. op. i. p. 74. 



Obs. There is found on the coast of Kauai a species, the male of which is almost 

 inseparable from P. congrmis and P. hatvaiiensis. Until the female is discovered, it, 

 however, would be rash to consider it as being identical with either of these species, as 

 the males of Pseudopterocheilus exhibit specific differences much less strongly than the 

 females.
