558 Descriptive Catalogue [1896. 



depression on each side, extending from the clypeus to past the 

 median part of the eye, and leaving only a narrow smooth median 

 space, central and posterior part of head smooth ; prothorax as long 

 as broad, rounded laterally in the anterior part, a little narrowed and 

 subsinuate behind, with the posterior angle sharp and projecting a 

 little, moderately plane but depressed basally, median longitudinal 

 line reaching from the anterior transverse impression to the base, 

 and deeper and broader there, the lateral basal impressions are 

 very broad and deep ; elytra twice as broad as the prothorax, truncate 

 at base with the shoulders rounded, parallel, not much sinuate 

 behind, convex in the posterior part, but hardly so in the anterior, 

 narrowly punctato-striate with the intervals convex and almost 

 carinate in the dorsal part, no puncture on third interval. Length 

 9 mm. ; width 4 mm.

 Bull. Mosc, 1873, p. 63. 



Mentum deeply but narrowly incised with a sharp, convex, median 

 tooth, much shorter than the lateral lobes which are slightly sloping 

 inwardly ; ligula triangular, apex broad, truncate, bisetose ; para- 

 glossae narrow, a little longer than the ligula and disunited from 

 it close to the apex, last point of palpi fusiform, very sharp at tip ; 

 mandibles sharp, curved, long ; labrum transverse, truncate at tip ; 

 eyes moderately prominent, two supra-orbital setae ; head straight 

 behind the eyes ; prothorax trapeziform, without any transverse 

 or median longitudinal impressions, but with two short lateral basal 

 ones ; elytra oblongo-ovate, fitting exactly against the base of the 

 prothorax, striate, no juxta-sutural striae ; legs short, femora thick, 

 strong; anterior tibiae dilated at apex; the three basal joints of the 

 anterior tarsi dilated in the male, cordiform, the basal one a little more 

 elongate than the two following, squamose in the middle rmderneath ; 

 posterior tibiae with one groove inwardly ; tarsi of intermediate and 

 posterior tarsi with one groove on the upper side. De Chaudoir 

 mentions, as characteristic of this genus, the undulated upper side 

 of the posterior tibiae, "showing several undulations separated by 

 little raised teeth which make them look as if they were tuber- 

 culated." This character, however, is not so apparent as De 

 Chaudoir makes it to be.
