PSILOMEKUS. 299 



lateral transverse spot on each of the first two abdominal segments 

 white. Antennae extend past the middle of the elytra ; first two 

 joints ferruginous, the rest dark brown, faintly covered with grey 

 pubescence ; third, fourth and fifth distinctly spined at the apex, 

 the spine on the fourth longest. Prothorax rounded at the sides, 

 narrowed at base, its surface reticulate-punctate. Episterna of 

 metathorax overlapped in front by the sides of the elytra. 



Length 6-7 ; breadth 2 mm. 



Hab. Southern India : Mlgiri Hills. 



This species is allied to D. formicoides, Lameere ; it resembles it 

 in form and to a considerable extent also in its markings, but the 

 bands of the elytra are all ashy-white in colour, and instead of 

 three spots in front there are two oblique, very slightly curved 

 bands which meet at the suture ; occasionally, however, these 

 bands are slightly interrupted, appearing then as three spots.

 and the apices white, the breast and sides of the abdomen beneath

Narrow and elongate in form. Head with a feeble elevation on 

 each side between the antennae ; face subvertical, rectangular, 

 longer than broad ; eyes rather small, feebly emarginate. Antennae 

 slender, filiform, a little longer than the body in the d" , shorter in 

 the $ ; third joint not longer than the fourth, as a rule much 

 shorter, armed with a long slender spine at the apex, the spine 

 cylindrical, not widened at the base, sometimes thickened at the 

 extremity ; fourth and following joints unarmed. Prothorax 

 longer than broad, subcylindrical, nearly as wide at the base as in 

 the middle, slightly narrowed in front. Elytra a little broader 

 than the prothorax, more or less parallel-sided, truncate at the 

 apex, the lateral margins nearly straight. Legs long, slender ; 

 femora gradually thickened from near the middle, the hind pair 

 extended some distance beyond the apex of the elytra ; first joint
