front opposite the eyes, rapidly, arciiately narrowing from the base. Elytra 

 shavply, conspicuously margined, with an indication of a faint groove along 

 the suture. Legs long, stout, the posterior pair with very broad femora, 

 curved, widened tibiae, and long upper tibial spur. 



Length 3i, breadth 2 mm. 



Hah. Penaxg {G. E. Bryant: 31.X.1913). 



One male, with the genital armature partly extruded. More convex 

 than the Bornean S. sulcigerns, the antennae stout and tapering, black, 

 except at the base and tip, the pmicturing of the upper sui-face much 

 sti'onger. The stout antennae, oval body, and robust build separate 

 S. crassicornis from the various other black species of the genus known 

 to me. The female is almost certain to have the elytra foveate or sulcate 

 towards the apex. 



49. — Scirtes scajjliiformis, n. sp. 



Elongate, subparallel, shining, thickly and rather coarsely pubescent ; 

 brown, the antennae, palpi, legs, and under surface testaceous or rufo- 

 testaceous ; densely, finely, the elytra rugosely, and the under surface very 

 densely, minutely, punctate. Head broad, the eyes large; antennae long, 

 rather slender, joints 2 and 3 short, equal, 4-11 elongate, each a little 

 thickened towards the tip. Prothorax very broad, rapidly, arcuately nar- 

 rowing from the base, deeply hollowed in front opposite the eyes, the anterior 

 angles deliexed. Elytra unusually elongate, subparallel ( 5 ?), or gradually 

 narrowed from a little below the base (c??)? Ci)njointly rounded at the tip, 

 flattened on the disc and with indications of obsolete costae, the reflexed 

 margin prominent to about the middle. Prosternum with a long, narrow, 

 spiniform process, which is received in a deep groove in the mesosternum. 

 Metasternum very short. Abdomen elongate. Posterior coxal plates trans- 

 versely subquadrate, arcuato-emarginate behind. Posterior femora enormously 

 developed; posterior tibiae short, straight, broad, sharply carinate, the spurs 

 curved, stout, the long upper one shorter than the first tarsal joint.

Described from three specimens recently captured by one of my 

 sons in India. There is also an example of it in Fry's collection, 

 labelled ''Malay (Casteln.),'^ perhaps in error. This species should 

 perhaps be taken as the type of a separate genus, owing to the long 

 prosternal process, the short, straight posterior tibiae (about reaching the 

 apex of the elytra when the legs are pushed backward), and the unusually 

 elongate elytra and abdomen. S. longipemiis Pie (1915), from Java, 

 may be allied to it ; but in the " description abregee " nothing is said 

 about the structural characters. S. elonyatm Waterh., from Hong Kong, 

 is perhaps the nearest form known to me.
