HYMENOPTERA 6 1 5 



flagellar joints moniliform, not transverse, the pedicel and first funicle joint cylindrical, 

 the former slightly the longer, both being decidedly elongate. Thorax not quite so dull 

 as the head, the mesonotum with shallow sparse punctures, the rest almost impunctate, 

 but with minute surface sculpture. Wings subinfuscate, stigma and parastigma dark 

 fuscous, the veins lighter, but still dark. Abdomen smooth and shining, the apical 

 margins impressed so as to make large angular emarginations in the surface of the 

 segments in the middle. Length 3 — 3-5 mm. 



In some examples the abdomen is nearly uniformly dark brown. 



Hab. Oahu ; 1500 ft. and upwards. 



HoLEPVRis Kieff 



( I ) Holepyris f hospes, sp. nov. 



Black, the antennae and legs ferruginous, the coxae mostly dark brown, the front 

 femora posteriorly and the hind ones outwardly more or less infuscate or darkened, 

 mandibles, clypeus, apical abdominal segment, and the impressed margin of the pro- 

 notum also ferruginous. 



Clypeus with a longitudinal median carina, head dull, finely and not densely, but 

 distinctly, punctured, eyes pilose. Antennae 13-jointed, the pedicel subequal to or 

 rather longer than the first funicle joint ; joints of the funicle mostly subequal and a 

 little longer than wide. Pronotum as long as the mesonotum and scutellum together, 

 very dull and very finely punctured, the punctures of unequal size. Mesonotum much 

 shorter than the scutellum, the latter with a transverse basal impression, both dull and 

 finely punctured ; propodeum longer than the mesonotum and scutellum together, 

 abruptly truncate posteriorly, the truncation margined ; a median raised line reaches 

 right through to the truncation, on each side of this are two ler lines, which do not 

 attain the truncation, and between all these lines the surface is ^ igreened ; external to 

 these lines, between the outer ones and margined sides of the pr,podeum the surface is 

 obliquely rugulose. There is a well-developed tooth on the underside of the claw of 

 the anterior tarsi near its middle. Wings hyaline, neuration yellow, stigma divided in 

 the middle by a white space, so as to form a prostigma, at least not much less developed 

 than in Sierola. Abdomen smooth and shining, the apices of the segments except the 

 first pale. Length, ? 4*5 mm. 



Hab. Oahu ; Honolulu. 



Obs. This species seems to me certainly congeneric with Epyris hawaiiensis 

 Ashm., which Kieffer refers to his genus Holepyris. E. haivaiiensis is a domestic 

 species, common in houses, and rarely seen outside. It is certainly introduced, as also 

 is H. hospes now described.
