orange of the abdomen, by the clouded wings and long venation 

 and by the long first joint of the antennal funicle. It is allied to 

 spinozai, but could not be confused with that characteristic species. 



2. Gonatocerns spinozai Girault. 



At the same time that the above new species was captured 

 Mr. Dodd obtained a pair of this species. The male was unknown 

 and, since it differs considerably in coloration from the female, I 

 briefly point out its characteristics. In structure, similar to the 

 female, but the antennae are 13-jointed and filiform, the pedicel 

 very small and sublobate, funicle joints 2-4 and 9-10 subequal, 

 longest, about thrice longer than wide; joints 1 and 5 subequal; 

 somewhat shorter than the others; joints 13, 6 and 7 subequal, 

 still somewhat shorter; joint 8 shortest, a third shorter than joint 2. 

 Abdomen subpetiolate, declivous from above at base, ovate, 

 striped dorsad with black, transversely (6 stripes counting the 

 broadest at extreme base). Propodeum purplish black, its spiracle 

 very minute, round, the surface finely reticulated, a median carina 

 present (its exact shape not seen, probably paired). Tip of dorsal 

 abdomen black. Otherwise coloured as in female. When mounted 

 in balsam, the tip or apex of the declivous part of the base of the 

 abdomen closed up to the thorax, partially concealing the real 

 nature of the segmentation; this apex is projected or heeled, stopper- 

 shaped and appearing as if it was intended to fit against the thorax. 



3. Gonatocerus fasciativentris , new species. 



Male. — Length 1.15. mm. 



Black, the abdomen golden yellow, conspicuously striped 

 transversely with black above and below, the intervening yellow 

 stripes much narrower, the lateral line yellow (about six black 

 stripes). Legs yellowish brown, the coxae black. Wings hyaline, 

 the fore wings of the less graceful type, the marginal vein moder- 

 ately long; fore wing with about twenty-five lines of discal cilia; 

 posterior wings narrow. Scape, pedicel and first funicle joint more 

 or less suffused with yellowish. Antennae strongly longitudinally 

 striated, the funicle joints short and subequal, each about one and 

 a half times longer than broad. Allied with coethei, but, besides 

 the differences in coloration, the fore wings are broader. Pedicel 

 only half the length of the first funicle joint.
