Banchogastra Ashm.

Female black, the front tarsi somewhat brownish, the wings hyaline, iridescent, 

 only slightly infuscate. 



Mesonotum very densely and finely punctured, the propodeum dull and rugose 

 behind the transverse carina, in front of this smoother and more shining-. Abdomen 

 narrow, the second segment nearly parallel-sided, elongate, one and a half times (or 

 more) as long as its basal width. 



Closely allied to B. nigra but distinguished by its comparatively clear wings and 

 long second abdominal segment. Length 9 — io'5 mm.

Pycnophion Ashm. 



( 1 ) Pycnophion fuscipennis, sp. nov. 



Rufous, the head, a median stripe on the mesonotum and the abdomen black. 

 Legs mostly black, but the coxae for the most part (the hind ones being more or less 

 dark) are red, as well as the extreme apex of the trochanters and base of femora of the 

 middle and hind legs. Posterior orbits narrowly yellow and the anterior ones to the 

 height of the antennal insertions. Wings shining fuscous, and iridescent. 



Eyes very large, there being a short cheek between these and the mandibles, 

 the first funicle joint of antennae nearly as long as the next two together. Mesonotum 

 dull, finely punctate, the propodeum without a transverse carina, irregularly finely rugose. 

 Ovipositor rather short, extruded to about the length of the three preceding dorsal 

 segments. Female. Length 9 mm. 



In this species the first recurrent nervure is almost interstitial with the discoidal. 



Hab. Kauai, 3000 ft. and at lower elevations.
