longitudinal carina present, anteriorly flexed hiterad, forming a very acute angle 

 with the antebasal carina. Elytra truncate at base, pleural edge not angulate 

 at base. 



Type : B. gounellei spec. nov.

60. Barra gounellei spec. nov. 



(?. Brown above, irrorated with clayish grey ; rufescent beneath, pubescent 

 grey. Rostrum about one-fourth longer than broad, with a shallow snlibasal 

 mesial impression. Antenna rufescent, rufous at base, reaching to middle of 

 elytra or beyond, segments and Itt brown, 11 Inteous. Pronotnm granulosc- 

 rugulose, convex, a basal mesial clayish patch, produced forward as a line to 

 middle of disc, accompanied at each side by a black basal spot, upon which follows 

 at base laterally a small clayish spot, a thin indistinct apical mesial line also 

 clayish, single clayish grey scale-like liairs scattered over the surface, as is the 

 case on head and elytra. Scntellum clayish. Elytra convex, rounded-narrowed 

 from middle backwards, coarsely ]mnctate-striate, de])ressed at base, alternate 

 interspaces with elongate clayish sjiots. Pygidium semicircular. Prosternum 

 finely granulose. Sides of meso- and metasternum impnnctate. A broad siabbasal

07. Lagopezus lugubris spec. nov. 



(J. Similar to temiicornis (18Ul) Eabr., shorter and broader. Segment 8 of 

 antenna longer than 9. Dorsal carina of ju-otborax five times sinuate. First and 

 second interspace of elytrum flat, not tesselated, third with two black tubercles, one 

 in middle, the other farther back, interspaces 5 and 7 also with some black raised 

 dots. First tarsal segment shorter than in tenuicornis, claw alone rufous.

1 S. 



Piezonemus gen. nov. 



(? ? . Rostrum at least twice as broad as long, apical margin laterally very 

 oblique. Eye elongate-elliptical, oblirpie. Antennal cavity underneath eye, not 

 in front of it. Frons trapeziform. Pygidium of S rounded at apex, marginate, 

 much longer than broad ; of ? tuberculate before ajjical edge, broadly sulcate 

 mesially, the sulcus divided basally. Midtiliia of S with tooth at ajiex, first 

 midtarsal segment dilated at apex on ijinerside; hiudtibia of 6 with a crest of 

 long soft hairs. Carina basal, angle acute. 



Type : P. darus spec. nov. 



Closely allied to Piezocori/iuis, but recalling by the pygidium of the ? also 

 Corrhecerus and Neiiiotrichus. It differs from the former esjjecially in the long 

 eye projecting forward above the antennal groove and being very obliijue.
