FEUHSTORFEEIA.. 49 



closely punctured, with their apices rounded and the apical calli 

 prominent. The femora and tibiae are slender, the front tibise 

 stouter, and armed with three sharp teeth, the middle and hind 

 tibiae smooth, without ridges or spines at the outer edge. The 

 tarsi are slender, but sliort. The pygidium is shining and very 

 sparsely clothed with minute hairs. 



(S . The mandibles are slender, acutely pointed, and calliper- 

 shaped. 



1 have not seen the female, which, according to Ohaus, is 

 uniformly light reddish-brown above, coarsely punctured, and 

 scarcely shining, with the femora and tibiae yellow, and without 

 any lateral thickening of the elytra. 



Length (without mandibles), 17 mm,; breadth, 9*5 mm.

Type in Dr. P. Ohaus' collection. 



The only specimen of this species that I have seen (in the 

 British Museum) probably represents a minor development, and 

 the mandibles may be found to attain considerably larger dimen- 

 sions. The species bears a very close resemblance to the Indo- 

 Chinese F. Q-mamlata, Kraatz, bat it is narrower in shape, the 

 head and scutellum are smaller in proportion, the elytra are 

 uniformly shining, instead of dull at the sides, and their apices 

 are rounded, instead of being squarely truncated. The triangular 

 depression on the head is also peculiar. The mandibles of the 

 small specimen here described are about 3 mm. long. In a well- 

 developed specimen of F. 6-maculata they measure about 15 mm., 

 and it is quite possible that they attain a similar or even greater 

 development in the present species. Ohaus gives the dimensions 

 of the male as 17-5 to 20 mm. in length, 9-5 to 11 mm. in breadth, 

 but omits to say whether, as is probable, the mandibles are 

 excluded. The female measures 15 to 20 mm. long by 9 to 

 10"5 mm. broad.

Deep red, with the lower surface and legs a little paler in 

 colour, except the tarsi, which are dark. The lower surface and 

 pygidium are fairly closely clothed with tawny hair. 



It is a short, compactly built, and moderately convex insect 

 with short stout legs, each of the four posterior tibiae bearing 

 a transverse spinose ridge on its outer face, the hind tibia broadest 

 at the end, and the hind femur very short and thick. The short 

 tubercular prosternal process is tufted at the end. 



d . Very short, robust, and parallel-sided, with the head 

 coarsely punctured, the clypeus small, narrowed and rounded at 

 the apex, the mandibles produced (about as long as the head), 

 strongly recurved and acute at the tips. The prothorax is trans- 

 verse, rather strongly punctured, with the sides parallel behind,
