Genera and Species of Indian Mantidge. 221 



temora similarlj shaped, but armed for the apical three fourths 

 of their length ; tibias very long and slender, of uniform width 

 and perfectly straight up to the base of the terminal claw, 

 armed with 5 spines on the outer edge, the basal two thirds 

 of which are unarmed, and with 11 on the inner, rather less 

 than the basal half of which is unarmed. Four posterior legs 

 very short ; the femora stout, slightly tapering at either end, 

 with a transversely convex rib on each side between the upper 

 and lower crests, prismatic, with each of the four angles 

 slightly crested ; the two upper crests minutely notched or 

 spinulose here and there, and converging apically to form the 

 strong triangular lobe that projects over the knees ; the two 

 lower ones are each also prolonged into a very sharp spine at 

 their apex ; the outer of them is simply, rarely, and minutely 

 spinulose, but the inner is furnished with three subtriangular 

 foliaceous lobes ; tibi^ and tarsi slender and weak.

 Reedy, of H.M. 45th Regiment, from whom I have received 

 a number of interesting insects from the same district. 



Genus SCHIZOCEPHALA, Serville. 

 Subgenus Didymocoeypha, nov. 



Body slender, sublinear. Antennce inserted and constructed 

 precisely as in Scliizocepliala hicornis^ but not thickened at 

 the base. Head very narrow and enormously elevated, the 

 lateral or ocular lobes of the vertex being vertically prolonged 

 in the form of two slender gradually tapering cones, which are 

 in contact with one another throughout their whole length, 

 occupying the whole of the vertex, so that the median lobe of 

 this part is not developed and that the grooves bounding its 

 lateral lobes meet upon the occiput at the basal junction of the 

 cones. Ocelli minute and hidden, just as in B. bicornis. Th© 

 face substantially as in this form and in Oxyophthahna chaly~. 

 hea. Eyes perfectly lateral, but little salient. Prothorax 

 narrow, with its sides subparallel ; its front and hinder mar-.
