black. On the abdomen, the post petiole, the apex of the second 

 segments, the band roundly widened backwards in the middle, a 

 broad band on the third segment, widest in the middle, and the 

 greater part of the penultimate segment, yellow. The gastro- 

 coeli are rufous. 



Chrysocryptus, gen. no v. 



Head and thorax densely covered with longish hairs, the 

 abdomen sparsely haired. Median segment areolated ; the 

 transverse and longitudinal keels distinct; the areola large, 

 twice longer than wide. Stigma conspicuous, wide, obliquely 

 narrowed towards the base and apex. Areolet large, wide, not 

 much narrowed above, five-angled. Radial cellule wide ; the 

 basal abscissa of the radius shorter than the apical and more 

 curved than it ; there are no nervelets on the disco-cubital and 

 the recurrent nervures ; the transverse basal nervure is inter- 

 stitial. In the hind wings the cubitus is broken shortly below the 

 middle. Head, if anything, wider than the thorax; the occiput 

 rounded ; eyes large, distinctly projecting ; the malar space 

 small. The middle lobe of the mesonotum is distinctly separat- 

 ed ; the parapsidal furrows are deep and reach near to the 

 scutellum. The furrow at the bottom of the mesopleurse is 

 distinct. The spiracles are linear : the spiracular area is well 

 defined, as is also the area at its apex. The base of the metanotum 

 is obliquely depressed. Ovipositor projecting ; the sheaths are 

 covered with longish white hair. Legs slender ; the hinder 

 coxae and trochanters longish ; the fore tarsi are longer than the 

 tibiai. 



The first three joints of the antennae are much lengthened, 

 being fully four times as long as wide at apex, or longer ; the 

 abdomen is twice the length of the head and thorax united ; the 

 disco-cubital nervure is roundly curved, not angularly broken ; 

 the clypeus is roundly convex ; its apex broadly rounded. The 

 face is densely covered with golden hair. The median segment 

 is completely areolated ; the area3 are all large and have stout 

 keels ; the areola is rounded at the base, transverse at the apex ; 

 the lower part of the metapleurre is stoutly keeled ; the radius 

 is thickly pilose at the base; the apical nervures in the hind
