1442 COLEOPTERA 



Vitiacus (Gen., p. 1087, Part V.). 



2501. V. COSticollis, 1^-s. Elongate - oblong, not parallel, 

 opaque ; fuscous, the sides of the thorax paler ; legs and antennae 

 reddish. 



Head feebly bi-impressed longitudinally, with ill-defined granular 

 sculpture. Eyes small but distinct. Antcnnoi shining, sparsely 

 pubescent ; second joint much thicker and rather longer than the 

 third ; first wholly concealed above ; ninth rather broader than the 

 eighth; club abruj)tly two-jointed, pubescent. TAoraa: rather longer 

 than broad, very slightly wider near the front than it is elsewhere, 

 a little sinuate behind the middle, its sides widely explanate, the 

 lateral margins not serrate, but with serial tubercles ; hind angles 

 somewhat obtuse, the anterior but little prominent ; the dorsum is 

 on an abruptly higher plane than the sides, with granular sculpture, 

 near the middle there are two raised rows of granules which form 

 costse. Elytra of the same width as the base of the thorax as far 

 as the middle, beyond that point moderately narrowed ; the sculpture 

 near the sides appears to consist of punctures or granules, according 

 to the light in which they are seen ; the dorsum is raised like the 

 thorax, it has two rows of granular elevations on each side of the 

 suture ; the third interstices are carinate, with short interruptions 

 behind the top of the posterior declivity, at that part the suture is 

 bisinuate, there is an elongate elevation behind the middle of each 

 elytron, near the side, and a sort of nodosity at each side near the 

 apex. 



Prosternum slightly emarginate in front, shorter in the middle 

 than at the sides, with a cavity at each front angle for the accommo- 

 dation of the antennae in repose. Breast convex, but with a de- 

 pression before the hind coxae. Abdomen with the three middle 

 segments equal. 



The thoracic costte, and the sculptiu-e of the hind-body, are dis- 

 tinguishing characters. 



Length, If lines; breadth, nearly f line. 



Capleston. I am indebted to Mr. Cavell for my specimen. 



Syncalus (Gen., p. 200). 



2502. S. munroi, ''••^- Oblong-ocal, convex, fuscous, sometimes 

 paler ; antennse, tarsi, and palpi red ; legs dark obscure-red. 



Head depressed, smooth, and somewhat shining, across the 

 middle ; the front red, raised, and closely granulate. Labruni and 

 mandibles reddish, large and exposed. Antennce sparingly pilose ; 

 the uncovered jDortion of the basal joint not longer than the second ; 

 third as long as the preceding one, but only about one-third of its 

 breadth ; joints 4-8 decrease in length ; ninth half the size of the 

 tenth ; eleventh largest. Thorax transverse, a little narrowed 

 anteriorly, its sides nearly straight at the middle, the base with a 

 sinuosity near each angle ; posterior angles nearly rectangular, the 

 anterior extend as far as the middle of the eyes ; disc transversely 

 convex, uneven, with four or five ill-defined impressions, and in-
