Syrichthus verus, Burm., 



Plate XL., fig. m.{;^. 5£. 

 Handb. d. Entom., v., 1847, p. 168. 



Piceous black, sliining, fringed along the prothorax, and also past 

 the median part of the outer margins of the elytra, with very dense 

 and long chestnut-red hairs ; head rugose, clypeus very short, 

 truncate at tip and bearing a small hooked tooth in the male, while 

 the female has a sharp tubercle situated in the centre of the head, 

 the posterior part of the head is deeply excavated in the male, but 

 not in the female, and the excavation is bounded by a sub-basal 

 transverse carina ; prothorax simple in both sexes and covered with 

 deep, closely set punctures ; scutellum impunctate ; elytra covered 

 with deep, round punctures regularly seriate, the striae are little 

 distinct, but they are indicated by a series of long, almost bristly 

 recumbent fulvous setae, distinctly remote and springing from one of 

 the punctures in the striate, dixplicate row, but also from between 

 the two rows in the basal part, these setae are, however, often 

 rubbed off; pygidium very rugose but with a smooth, triangular 

 apical space in the male, equally rugose in the female, with the 

 transverse concave part densely pubescent in this sex ; four basal 

 abdominal segments nearly impunctate in both sexes in the middle, 

 and having only one row of setigerous punctures in the two apical 

 ones in the male, but these two segments are very roughly punc- 

 tured in the female, and very densely pilose. 



Length 18-24 mm. ; width 9i-13 mm.

SYEICHTHODONTUS, n. gen. 

 Mentum a little rounded laterally at base, then diagonally acumi- 

 nate until near the apex where the ligular part is hardly contracted 

 at all, and is deeply emarginate triangularly on the apical margin, the 

 anterior part is impressed on each side, the median part is sharply 

 carinate, and the slightly recumbent ligular part is deeply hollowed 

 in the middle ; palpi and maxillae as in Syrichthiis, the upper tooth, 

 however, being slightly bifid ; clypeus sharply triangular, reflexed 

 in a tooth at tip ; genae distinct, triangular ; mandibles long, sharp 

 at tip ; head with a small, sharp tubercle in the male ; prothorax 

 rounded and a little ampliate laterally, plane and with an anterior 

 impression containing a median tubercle in the male, more convex 

 in the female ; elytra depressed ; pygidium not convex in either
