punctata. Abdominis segmentum secundum elevatum ; subtus, costis subobsoletis, a 

 sulco fortiter elevatum, depressione angustula, minus alta. i. Long. 7 mm. 



Black, shining, wings dark with blue iridescence. Clypeus very slightly emar- 

 ginate at its apex ; head above the antennae rather finely and shallowly punctured. 

 Mesothorax with fine sparse and irregular punctures, between which the minute 

 system is evident, but not dense. Propodeum smooth, impunctate in front, the 

 posterior concavity with some very shallow punctures. Basal segment of the abdomen, 

 viewed laterally, forming an almost even curve from the petiole to the hind margin, 

 above somewhat irregularly and shallowly punctured. Second segment raised from 

 the base ; beneath, the depression neither very wide nor deep, the costae subobsolete, 

 and the segment rising at the side from their apices to a height rather greater 

 than that of its basal portion. <? . 



Hab. Mountains near Honolulu, i cT, March 1897.

 </?. Long. 7 — 10 mm. (Plate L fig. 23 and 22, a.)

 and scarcely punctured. Abdomen with the basal segment strongly transverse, with 

 very feeble, ill-defined, and sparse punctures ; second segment strongly raised from
