abdomen, except ultimate segment, very finely pubescent, each minute 

 hair springing from a minute pit, these smaller on head and prozona.* 

 Head otherwise similar to that of quadrispinosa. Antennae with 

 first and third joints subequal in length, fourth joint about half 

 again as long as broad.^ Tegmina and wings fully developed, broadly 

 rounding laterad, not showing a feeble percurrent keel as in quad- 

 rispinosa. Dorsal surface of abdomen without projections, but with 

 segments, to the penultimate, milled at their caudal margins; ultimate 

 segment narrower than in quadrispinosa, width not two and one-half 

 times length,*^ with a decided medio-longitudinal sulcus and with 

 surface showing microscopic, irregular, impressed lines, which are 

 strongest meso-distad. Pygidium declivent, large, fitting tightly 

 between forceps, roughly rhomboidal, with distal portion curving 

 inward and margin there broadly convex, surface convex distad, 

 showing two minute, blunted projections. Forceps elongate, internal 

 margin broadly concave in slightly more than proximal half, with 

 minute widely spaced teeth, thence straight, with more numerous, 

 slightly larger serrations to the distal third of this portion where it is 

 concave and smooth to the apex: shaft in proximal fourth heavy, 

 triquetrous, tapering, with dorsal margin smooth, thence slender, 

 nearly cylindrical to slightly beyond middle point, where it is slightly 

 enlarged and more flattened horizontally, tapering distad to the acute 

 apex. Ventral surface of abdomen strongly pubescent, distal margin 

 of penultimate segment subtriangularly convex. Limbs rather long, 

 slender; caudal metatarsus hairy, in length equalling that of the 

 third tarsal joint, with a heavy fringe of hairs along the external 

 margin; tarsal claws elongate and slender. 



Length of body, 16.2; of pronotum, 2.4; of tegmen, 4.9; of forceps 

 8.; width of pronotum, 2.3; of ultimate dorsal abdominal segment, 

 3.2 Him. 



Head, pronotum, tegmina, exposed portion of wings and abdomen 

 chestnut brown, slightly darker on face, shading to claret brown on 



^ In quadrispinosa the head is much more weakly pubescent, the prozona 

 almost smooth and hairless, the tegmina and exposed surface of wings more 

 polished, finely granulose and hairless, and the metazona and dorsal surface of 

 the abdomen, except the ultimate segment, is more thickly and minutely granu- 

 lose, with hardly any hairs. 



5 In quadrispinosa the first joint is longer than the combined length of the 

 second and third, the fourth joint as broad as long. 



^ Burr's figures show, in his Fauna British India, Dermapt., that he meant 

 rectangular, when he characterized this segment as square, for the species of 

 Forcipula.
