HYMENOPTERA 629 



DiAPRiA Latr. 

 (i) Diapria drosophilae, sp. nov. 



Black, the thorax, abdominal pedicel and sometimes the second segment more or 

 less red or dull red, in the ^ the thorax is sometimes nearly black or only slightly 

 reddish tinged ; antennae in the $ red excepting the dark club, in the $ the two basal 

 joints only are wholly yellow or red, but the basal stalk of the other joints is usually 

 red, legs yellow with the apical joint of tarsi dark. 



Head smooth and shining, with sparse long hairs, and a patch of pale pubescence 

 along the sides of the occipital margins. Antennae of the male very long, the pedicel 

 not as long as the first funicle joint, which is much shorter than the following and lacks 

 the long basal stalk, the second and following joints of the funicle are subequal, each 

 with a very thin stalk, as long or longer than the thickened apical part of the joint, 

 which bears a whorl of long hairs ; the apical funicle joints are noticeably shorter than 

 the basal ones, the terminal joint being the smallest of all. Antennae of $ short, with 

 well-marked three-jointed club, the pedicel much larger and longer than the first funicle 

 joint, which with all the following joints is elongate or subelongate, the seventh funicle 

 joint is noticeably wider than the preceding, but still much less wide than the basal 

 joint of the club. Thorax polished and bearing sparse long hairs, the pronotum densely 

 clothed with appressed hair ; scutellum foveated at the base, propodeum with a median 

 carina forming a projecting angle anteriorly, in lateral aspect, pubescent on each side. 

 Abdominal petiole short, about as long as wide in the ?, rather longer in the $, hairy 

 and with appressed pubescence ; the rest of the abdomen smooth and polished. Wings 

 subinfuscate, the cilia shortish. Length about 2 mm. 



Hab. Oahu, Honolulu; commonly parasitic on introduced species oi Drosophila. 



(2) Diapria xettica, sp. nov. 



Male black, the two basal antennal joints and all the legs yellow. 



Head globose, polished, clothed with sparse pale hairs ; antennae with the funicle 

 moniliform and with whorls of long hairs, the pedicel very much shorter than the first 

 funicle joint, which is subequal to the second, these two being the longest, but the latter 

 is more incrassate, and in one aspect concave on one side, convex on the other, the 

 following joints have at the most a very short stalk and are ovate, the several subapical 

 joints being shorter than the basal ones and nearly round, the terminal joint somewhat 

 shorter than the two preceding together. Thorax smooth and polished, sparsely clothed 

 with erect hairs, the prothorax with a pubescent collar, the scutellum with a basal 

 impression ; propodeum dull, with a median carina. Wings hyaline, pubescent, with 

 rather short cilia, the stigma yellow. Abdominal pedicel hardly longer than wide,
