with a slight golden gloss; elytra with paler markings and 

 with dense setas, usually slightly- darker than the scales 

 amongst which they are placed. 



Kostrum tricarinate, carinas normally concealed, but 

 median one rather acute, the longitudinal depressions with 

 rather coarse but concealed sculpture. Frothorax mode- 

 rately transverse, sides moderately rounded, base not much 

 wider than apex; with rather coarse partially concealed 

 sculpture, but leaving a feeble median node exposed. Elytra 

 considerably wider than prothorax, very feebly dilated to 

 beyond the middle; with very large punctures in strise, but 

 appearing much smaller through clothing. Length (exclud- 

 ing rostrum), 11-13 mm.

The larger of the two specimens before me is (except 

 as to its clothing) of an almost uniform reddish-brown, whilst 

 the smaller one is black, but with parts of the appendages 

 diluted with red. On each elytron of the larger specimen, 

 just before the summit of its posterior declivity, there is a 

 small patch of white scales, extending across two interstices, 

 and vaguely connected with the shoulder by a stripe of scales 

 slightly paler than most of those on the elytra; on tlie 

 smaller specimen these markings can be just traced. They 

 appear to be remnants of the V common to several species 

 of the genus. The elytral setas are not in two almost regu- 

 lar rows on each interstice (as in the description of Rivu- 

 losys), but are fairly dense, and although not in regular 

 rows, generally three or four (sometimes more) can be traced 

 at any one line between the interstices. 



Catastygnus ochreipennis, n. sp. 



Black, elytra and parts of legs obscurely diluted with 

 red, scutellum dull red. Densely clothed with greyish or 

 light-brown scales, thickly interspersed with fine setae; but 

 elytra with decided ochreous scales and seise, except towards 

 the sides, where the clothing is mostly black or sooty. 



Rostrum tricarinate, the median carina acute and shin- 

 ing, the others less regular; sublateral sulci almost as deep 

 as scrobes. Prothorax rather lightly transverse, sides mode- 

 rately rounded ; base distinctly wider than apex, granulate- 

 punctate; with a distinctly impressed median line. Scutel- 

 lum distinctly transverse. Elytra distinctly but not much 

 wider than prothorax, sides feebly dilated to basal third ; 

 with large but partiallv concealed punctures in striae. Length, 

 12J-15 mm.
