NEW INDIAN ICHNEUMONID^. 725 



median nervure in hind wings broken shortly below the middle, but the 

 longitudinal nervure is very faint, almost obsolete. Median segment long ; 

 with 2 stout transverse keels, the spiracles about 3 times longer than wide, 

 clypeus roundly convex, clearly separated from the face by a suture, 

 its apex broadly rounded. Eyes large, parallel ; the malar space small. 

 Scutellum longish, narrowed towards the apex, which has a long, oblique slope; 

 its sides are margined. Legs long, slender ; the hind coxa) long, about 4 times 

 longer than wide ; claws simple. Occiput margined, almost transverse. Fii-st 

 abdominal segment long, slender, cylindrical, shghtly dilated at the apex ; the 

 spiracles prominent placed shortly before the middle ; the segments become 

 slightly gradually widened to the last, which is obliquely narrowed. 



The antenntE are longer than the body, filiform. Hinder calcaria short, not 

 half the length of the 2nd tarsal joint, ocelli large, the hinder separated from 

 each other by a slightly less distance than they are from the eyes. Temples 

 wide, obliquely narrowed ; the occiput has a sharply oblique slope from the 

 ocelli and are margined. Parapsidal furrows indicated at the base, narrow. 

 Apex of pronotum dilated. Fore tarsi long, slender, clearly longer than the 

 tibis. There is a wide depression on the lower apical half of the mesopleuraj 

 and a shorter narrower curved one on the base of the mesosternum. Pteros- 

 tigma large, longish, the radius issues from shortly beyond its middle, the 

 transverse cubital nervure is short. Mandibles unequally bidentate. 



The precise affinities of this genus may be left over until its $ is known. 

 From the position of the abdominal spiracles I refer it, for the present, to 

 the Tryphonidm, Tribe Mesoleptini. 

 Letosha longicoxis, sp. nov. 



Black, the face, clypeus, mandibles, palpi, a somewhat triangular mark on the 

 apex of the pronotum, the lower edge of the propleurse, the lower inner orbits 

 broadly, the mark gradually narrowed above and a narrow line down the base 

 of the metapleura), pale yellow, the apex of the scutellum, the apex of the 1st 

 abdominal segment narrowly, the base of the 2nd somewhat more broadly, the 

 base of the 3rd still more broadly, and the whole of the 3rd rufotestaceous. 

 Legs rufo-fulvous, the anterior paler ; the hind coxas, apex of hind tibife broadly 

 and the basal half of metatarsus black; the rest of the hinder tarsi white. 

 Wings hyaline, the stigma fusevus, the nervures black. 

 Length 8 mm. 

 Simla, August. 



Antennae filiform longer than the body, black, the pedicle testaceous, the 

 flagellum densely covered with short, stiff pubescence. Head, prothorax, me- 

 sonotum and scutellum smooth and shining, the lower part of the mesopleurai 

 closely, strongly, longitudinally striated, the upper part and the greater part of 

 the apex smooth and shining ; the metapleuras coarsely rugosely reticulated. 

 Basal part of metanotum smooth, depressed in the middle at the base ; its apex 

 irregularly, obscurely striated ; the part between the 2 keels is strongly, irregu- 

 larly striated ; the apex is irregularly striated laterally. Metapleuree coarsely
