joints somewhat moniliform. Abdomen subpetiolate. 

 Parapsidal furrows obsolete. Scutellum convex, rounded 

 at the apex, glabrous. Ocelli almost forming a triangle, 

 wings without nervures, deeply fringed. Tarsi 5 -jointed. 

 Vertex immarginate. 



Bred from Cecidomyia oryzce, Wood-Mason, a midge 

 which proved destructive to paddy in Moughyr in October, 

 1880. See Notes on Indiajt Economic Entomology ^ No. 2, 

 p. 103, pi. vi. f 6. 



The species of Pldtygaster greatly affect species ot 

 Cecidomyia^ most of which are gall markers. 



ApHELINUS THE^, Sp. 710V. (PI. I. f 5 & 5^). 



Yellow ; the legs pallid, with apex of the hinder tibiae 

 and tarsal joints infuscated. Head dilated behind the eyes. 

 The second antennal joint small ; the third large, thicker 

 than the second or fourth ; the fourth and fifth not half the 

 size of the third, and equal in length ; the club abrupt, 

 longer than the preceding four joints united ; the last joint 

 conical, apparently thinner than the penultimate. Hinder 

 tarsal spur as long as the metatarsus. Wings with a long 

 hair fringe. 



Length not ^ millim. 



The only specimen I have seen is mounted in balsam 

 and has got flattened, so that its exact shape cannot be seen 

 satisfactorily. Apparently there are two broad triangular 

 processes projecting from the thorax to near the middle of 

 the abdomen ; but their j3recise relationship or structure 

 cannot be correctly made out. They seem to proceed from 

 the base of the mesonotum. The sutures of the thorax 

 cannot be observed. I am not aware of any similar structure 

 being known in the family. It is so peculiar that I have no 

 doubt that it will be proved, on further examination, from 

 fresh specimens, of generic value — that the species forms the
