DESCRIPTION OF TWO NEW GENERA AND THIRTEEN 

 NEW SPECIES OF ICHNEUMONID^ FROM INDIA. 



By p. Cameron. 



ToKBDA, gen. nov. 



Head cubital, largely developed behind the eyes, which are large 

 and parallel ; the malar space is large. Clypeus not distinctly sepa- 

 rated from the face by a furrow ; its apex transverse. Labrum largely 

 projecting. Mandibles stout, their apex bidentate. Parapsidal fur- 

 rows distinct at the base. Pronotum tuberculate in the middle. Meso- 

 sternum indistinctly furrowed laterally behind. Median segment large, 

 rounded behind ; there is one transverse keel at the base ; the spiracles 

 are linear, not elongated. Areolet large, longer than wide ; the trans- 

 verse cubital nervures slightly converging above ; there is no stump of 

 a nervure on the disco-cubital nervure ; the transverse median nervure 

 is received behind the transverse basal ; the transverse median nervure 

 in the hind wings is broken at the middle. Legs elongate, stout ; the 

 tarsi spinose ; the fore tarsi are longer than the tibiae ; all the tarsi 

 are thickly spinose. Petiole stout, narrowed at the base ; the spiracles 

 are placed almost in the middle ; the penultimate segment is largely 

 developed, is nearly as long as the four preceding segments united ; 

 the last segment is distinctly longer laterally than the penultimate ; 

 its apex is depressed and clearly separated ; the cerci are long. The 

 antennae are long and stout ; the second and third joints are equal in 

 length ; the fore tibiae are distinctly narrowed at the base ; the claws 

 are simple ; the occiput is broadly incised, and has a distinct but not 

 sharp margin ; the scutellum is large, rounded, and hardly raised 

 above the level of the mesonotum ; the hinder coxa; are large, about 

 three times longer than thick ; the scutellar keels are thick. The 

 areolet is pentagonal, it being angled where the recurrent nervure is 

 received. In T. femorata, and in the luteous section of the genus, the 

 apex of the clypeus is obliquely depressed ; in the male of that species 

 the hinder tarsi are longer compared to the tibia. 



I am not quite certain as to the exact location of this genus, 

 or if it should form one or two genera. It has some affinity 

 with the Cryptina. The position of the spiracles on the petiole 

 separates it from tbe Cryptina. The very large hypopygium is 

 somewhat as in the Acoenitini, but it cannot be referred to any 

 of the described genera in that group. The depressed clypeus in 

 some of the species is similar to what it is in the Xoridini, and 

 they have some relationship to Echthrus. Probably the natural 

 position of Torhda is with the Xorides. The species are very 

 large and handsome — among the largest of the Ichneumonidae. 



A. Black, with white markings ; the legs fulvous, marked 

 with black and white. 

 1. Post-scutellum raised, depressed only laterally at the 

 base. Wings suffused with fuscous or violaceous, 

 not maculate. Large species.
