THE ENTOMOLOGIST. 15 



Descriptions of New Genera and Species of Parasites, 

 belonging to the Families Proctotrupidce and Chalci- 

 dida, which attack Insects destructive to the Fig in 

 India. By the late Francis Walker, Esq. 



[Communicated by F. Smith, Esq.] 

 Genus Pseudisa, n., Walker. Fam. Dryinoid^ ? 



Body convex. Head and thorax very finely squamous. 

 Head large, transverse, subquadrate, a little broader than the 

 thorax; front perpendicular. Mandibles very short. Eyes 

 large. Ocelli three, in a curved line on the vertex. Antennae 

 pubescent, filiform, 12-jointed, shorter than the thorax ; first 

 joint long, stout; second elongate-cyathiform ; third and 

 fourth extremely short ; fifth and four following long, linear, 

 equal; tenth, eleventh and twelfth forming a fusiform club, 

 which is a little less than twice the length of the ninth. 

 Prothorax large, quadrate. Mesothorax well developed ; 

 sutures of the parapsides distinct, converging hindward; 

 scutellum with a slight longitudinal furrow. Aletathorax 

 large, tapering. Petiole slender, cylindrical, about two thirds 

 of the length of the abdomen. Abdomen smooth, compressed, 

 with four nearly equal segments ; tip obtuse in the male, 

 aculeiform in the female. Legs stout, setose ; femora incras- 

 sated; tibiae curved; tarsi 5-jointed; claws moderately 

 long. Fore wings moderately broad, with a setose subcostal 

 vein proceeding from the base to a large stigma, which emits 

 a short branch or cubitus. 



PSEUDIA SMICROIDES. 



Luteous, with some black marks, which vary in number, 

 and occasionally are wholly wanting. Wings cinereous- 

 hyaline; subcostal vein tawny; stigma black. Length of the 

 body Ig- — 3 lines. One specimen, which is much larger than 

 the other, has a ferruginous stigma. Thirty-six specimens. 



The number of specimens of this species indicate that it is 

 especially an agent in caprification. It may deposit its eggs 

 in some larvae that feed within the fig, near the surface. It is 

 very different from all genera hitherto described. 



Genus Isanisa, n,. Walker. Fam. EuRYXOMiDiE. 



Body convex. Head and thorax very finely squamous. 

 Head transverse, subquadrate, as broad as the thorax. Parts
