Jaws bidentate at the end ; upper lip truncated in front, covered with 

 red stiff hairs. Antennae long, with only three short terminal lobes. Clypeus 

 uneven, but not punctated ; the central horn is flatly convex, smooth, trans- 

 versely very elongately subtriangular, anteriorly with a small projection, end- 

 ing in a small free point, from which diverge in a slight curve the frontal 

 ridges, terminating with distinct tubercles near the front edge. This frontal 

 edge has a sharp process above each of the two lateral margins of the upper 

 lip, the left appears to be occasionally a little larger than the right one, 

 recalling a similar structure in JBasilianus. The two frontal tubercles are 

 connected by a low ridge and the margin between them is deeply concave. 

 Supraocular ridges with a sharp point above each eye, flattened in front, 

 and externally at each corner terminating with a small spine. 



Prothorax moderately convex, with a distinct central groove, but not 

 extending anteriorly to the margin ; marginal furrow narrow, finely 

 punctated ; lateral scar forming a shortly elongated and smooth impression. 



Scutellum at base finely punctated and hairy, along each side of the 

 centre finel}^ strigated. Waist laterally densely punctated, below smooth, 

 somewhat transversely rugose, but without any special scar. 



Elytra with the shoulders somewhat swollen and projecting, smooth ; 

 all the furrows distinctly punctated. 



Tongue long, with a median and two marginal ridges, strongly 

 contracted in the lower half. Lower lip with its branches entirely punctated 

 and hairy, slightly depressed in the middle. 



Metastemum laterally densely punctated, but the posterior sloping 

 corners are smooth, which is also the case with all the abdominal segments. 



Prothorax at the lateral lower sides, and the median femora, covered 

 with dense, long, rufous-brown hair ; anterior femora, sides of metasternum 

 and hinder tibise a little less hairy. 



Hah. — Nilgheries and Malabar. I received originally two specimens 

 of this species from the Madras Museum, but since then several others 

 have been sent to me by Major Beddome and Eev. Baker. 



Kaup describes a single species, P. pilipes, from Sumatra. The 

 generic characteristics have to be slightly altered, but in all essential points 

 the South Indian species agrees with Pleurarius. 



9. Semictclits Eedtenbacheri, n. sp. 



Total length 25*4, width of clypeus 5*2, of prothorax 7'3, of shoulders 

 7*1, length of elytra 14'3 m.m. 



Jaws rather short, each with three denticles ; antennae moderately 

 elongated, the three terminal lappets well developed and equal ; upper lip 

 squarish hairy, very slightly concave at the front edge. 



Clypeus rugose, punctated on the forehead, front edge very slightly 

 emarginate in the centre, and with a small projection above the edges of the
