Rather small, elongate and a little depressed, the head and 

 the sides of the body beneath bearmg short reddish hairs or 

 setae. The club of the antenna consists of six long lamellae, 

 their extremities reaching a uniform level, and the last three 

 not conspicuously longer than the rest. The head is closely 

 punctured, the frontal area is nearly equilateral, the frontal 

 tubercles jolaced close to the front margin and the inner mar- 

 ginal j)rocesses acute. The pronotum is without marginal 

 groove or has only a slight vestige. The lateral scar is rather 

 large and contains fine setigerous punctures, which are also 

 numerous along the lateral margin and in a roundish patch 

 near the front angle. The elytral stripe are very finely punctured 

 and the punctures in the lateral striae are onlj^ a little stronger. 

 The basal part of the mentum is smooth in the middle. The 

 mesosternal scars are long and rough, the intervening area 

 more or less opaque, sometimes with a median keel. The 

 median area of the metaste.rnum has finely and scantily 

 punctured hind angles. The middle tihix bear short and not 

 very close fringes. 



Length, 25 to 27 mm. ; breadth, 9-5 mm.

Elongate and moderately convex. The pronotum very 

 smooth, without median groove. The lateral grooves of the 

 elytra very minutely punctured. The middle tibiae bearing 

 not very close fringes of short liairs.
