H J 'MENOP TERA 7 1 



scutellum with a very distinct raised line (usually serrulate or spinulose) at the trun- 

 cation. Propodeum rough with large, feebly impressed, punctures. Abdomen with 

 the second segment not raised from the base ; beneath, with a wide depression, but 

 shallow, meeting the apices of the costae obliquely, the costae themselves more or 

 less obsolete or indistinct. 



Hab. All over the islands from Oahu to Hawaii on the coast and as high as 

 4000 ft. in the mountains.

Black, the wings infuscate and with blue iridescence, the apical margins of 

 the two basal abdominal segments yellow. Of the same robust form as the pre- 

 ceding, and like that species with transverse basal segment of the abdomen, and a 

 raised line at the truncation of the postscutellum. On the mesothorax two forms 

 of puncturation can be made out in the c/, consisting of larger and smaller punc- 

 tures, the whole forming a dense and subrugose puncturation. In the ? the meso- 

 thoracic puncturation is almost identical with that of the preceding. The depression 

 of the second ventral segment is wide and shallow, the costae are less obsolete than 

 those of O. nigripeiinis . 



H.\B. Kauai, common on the coast and in the mountains, occupying the place 

 which O. iiigripennis holds on the other islands. It is evidently a directly modified 

 form of that species.
