hooks, and three transparent dots in the upper and two in the lower 

 inosculations of the nervules. 



" In Paniscus (No. 1 ) there are no sub-basal (??) and seven slightly 

 curved distal hooks, and two transparent dots in the upper inoscula- 

 tions of the nervules. 



" Paniscus glcwcopterus has one, or at least the very small scar of 

 one sub-basal, and fifteen strong distal hooks, which are curved and 

 furnished with an acutely recurved tip ; there are numerous transparent 

 dots in the elongate opake stigma, and three or four similar dots in 

 the lower inosculation. 



" Paniscus inquinatus has one distinct small sub-basal, and seven 

 distal hooks. 



" Besides the difference in the number of distal hooks in the species 

 of this genus, there is considerable difference in the form of the u{)per 

 nervules at the base of the wing. In P. inquinatus, the front 

 nervule is forked at the base, the two forks being far apart ; the 

 upper one is short, with the sub-basal hook at its tip ; and in P.glau- 

 cnpterus this nervule is flattened out, and the separation into two 

 forks is very indistinct and far from the base, and the latter has a 

 series of short, rigid, spine-like hairs in front of the series of the 

 upper edge of the wing. 



" Pimpla varico)-nis has one sub-basal and nine distal hooks, which 

 are slightly curved, and with a recurved apex. There is a black, 

 rigid, nearly straight, elongate bristle in front of the series. There 

 are two or three small transparent dots on the upper, and several also 

 on the lower inosculations of the nervules. 



" Ephialtes, sp., has one nearly straight sulj basal, and six arched 

 distal hooks ; their tips are not recurved. 



" Pimpla turionellce has one small, nearly straight sub-basal, and 

 seven arched, distal, rather weak hooks. 



^'Pimpla, sp., has one small and six rather weak, slightly curved 

 distal hocks. 



" In Ilemiteles the nervules are weak and rudimentary. There is 

 only one very weak, indistinct sub- basal, and four very weak, slightly 

 curved hooks in the distal series. 



" Cryptus has also rudimentary nervules, a very small, weak basal, 

 and six very slender, curved distal hooks. 



" The hind wing of the genera Ophion, Paniscus, and Pimpla, and 

 perhaps of the allied Hymenoptera, differs from the front one in the 

 upper marginal nervules being forked at the base, the upper bianch 

 being short and extended to the edge of the wing ; and it is on the 

 apex of this branch that the sub-basal spine or spines are situated. 

 The lower branch of the fork is extended to beyond the middle of 

 the wing before it reaches the margin, and there it forms the stigma 

 or subarticulated opake spot ; and it is on the extension of this branch 

 just beyond tlie stigma that the distal series of s{)incs are situated. 

 The edge of the wing between the two points of the fork is thin and 

 membranaceous. 



" The fore wings of these insects differ in the anterior nervules 

 being simplv, not forked, and forming the margin of the wing.
