HYMENOPTERA OF THE HAWAIIAN ISLANDS. 235 



Mayr, but it is^ I believe, P. obscura, for I cannot find 

 any trace of pubescence on the mesonotum. Mr. Black- 

 burn has taken the male, which has not been described. 

 It is dark brown ; the antennae are testaceous, the scape a 

 little darker than the flagellum ; the mouth, base of the 

 legs, and tarsi pale yellowish testaceous, the femora and 

 tarsi fuscous, pale beneath. Head and thorax shining, 

 finely shagreened, and bearing some longish (compara- 

 tively) blackish hairs. Abdomen shining, inipunctate, the 

 apical half bearing longish black hairs. Wings brownish 

 yellow, but not deeply, the nervures pallid testaceous. 

 The apex of the abdomen is pale yellow. The only speci- 

 men I have appears to be somewhat immature. 



The species has only been recorded from Australia.
