Elongate, rather convex, entirely smooth and hairless above- 

 On the head the supraorbital ridges are very sharply spined 

 above, the frontal ridges strongly rounded, ending in strong 

 tubercles placed just behind the inner marginal processes. 

 The /j/-0?w<!O/us extremely smooth, with median groove, which 

 reaches the basal margin but is abbreviated in front, the fine 

 marginal groove not dilated at the sides of the front margin. 

 The elytra are dee])ly sidcate, with rounded intervals, and both 

 dorsal and lateral grooves very minutely punctured. The 

 sides of the mesostemum are very finely and closely clothed 

 with hair. The sides of the metasternum are very broadly 

 densely punctured, the punctured area extending beyond the 

 lateral dej^ression and clothed with long thick hair. 



Length, 39 mm. ; breadth, 14 mm.

According to Gravely (Kec. Ind. Mus. xi, 1915, j). 496), 

 Pleurarius brachyphyllus is abiuidant in the evergreen jungles 

 on the lower western slopes of the Western Ghats in Cochin. 

 Occasionally, isolated pairs were found in a log, but usually 

 numbers were found together. It makes galleries well below 

 the surface of the burrows in somcMhat hard wood and is 

 very difficult to dig out.
