HYMENOPTERA OF THE HAWAIIAX ISLANDS. 2.23 



34. Odynerus agilis. 



Odynerus agilis. Smith, I.e. p. 681. 



To this species I attribute numerous individuals cap- 

 tured by me in various localities on Maui, Lanai, and 

 Hawaii. If I am riglit in doing so, this is one of the most 

 variable species of the genus, and the original description 

 needs the addition of the following note : — 



The degree of intensity with which the punctuation on 

 the thorax is impressed differs in almost every two speci- 

 mens, until in the extreme form no punctuation is visible 

 without the use of a lens, by means of which, however, it 

 is seen that the punctures of the type are present, only 

 with the appearance of having been very nearly oblite- 

 rated. The mandibles vary in colour to pitchy, and even 

 red. The yellow spot behind the base of the antennae 

 is generally absent. The postscutellum is occasionally 

 spotted with yellow. One or other, or both, of the yellow 

 rings on the hind body may be extremely indistinct or 

 wanting. The length varies from 12-16 millim. The 

 female does not noticeably differ from the male, except by 

 the usual sexual characters. 



The distinctive features of the species are its whitish 

 pubescence and the extremely strong emargination of the 

 apex of the clypeus, the edges of the emargination being 

 more or less strongly produced forwards in an almost 

 cylindric shape. 



35. Odynerus insulicola. 



O. insulicola, sp. nov. Subnitidus, pubescens, minus 

 crebre punctatus, niger, flavo-notatus ; alls subhya- 

 linis obscure cseruleo-iridescentibus ; clypeo antice 

 emarginato ; abdominis segmento basali transverse, 

 antice verticali. 



Long, c? ? 9"^ I millim.
