DORCUS. 93 



(J. The body is a little depressed. The head is slujrt and 

 broad, densely mieroscopieally granular, the elypeal jjrocess 

 very short and broad, with straight front margin. The man- 

 dibles are strongly roundetl, far apart at the base and rather 

 short. The canthus is obtusely angular in front of the eye 

 and the sides are contracted behind the eye. The pronotum 

 is short and broad, microscopically granular, the front angles 

 are rounded, the sides strongly sinuate in front, straight 

 behind and the lateral angle obtuse. The .scutellitni is slightly 

 shining. The elytra are very opaque, witli a feebly shining 

 sutural area, which dilates a little at the base and is finely 

 punctured. The mentum is rugose. The tnetasternutn is 

 smooth and shining in the middle, densely granular at the 

 sides, where there is a thin clothing of fine hair. The abdomen 

 is opaque beneath, with the sides slightly rugose and the last 

 sternite finely punctured. 



Variation of the male. In small specimens the short, 

 strongly curved mandibles are quite simjile in shape, but have 

 a slight blunt internal tt)otli upon the upper edge near the 

 base. With increasing size this tooth becomes stronger, 

 forming an acutely pointed triangle, and is situated farther 

 from the base. In the largest male I have seen it occupies 

 the middle of the mandible, which is about twice as long as 

 the head. 



tJ. Le^ig^^/i (with mandibles), 30-46 mm. ; (without mandibles) 

 27-32 mm. : breadth, 11-14 mm. 



$. Length, 30-36 mm. ; breadth, 12-15-5 mm.

Type in the Berlin Entom. Institute, also that of rotiindo- 

 punctatus ; that of .suturalis in the British Museum. 



I am indebted to Dr. Walther Horn for enabling me to 

 examine the two types in the Berlin collection. 



The oldest name of this species, that given by Westwood, 

 cannot be adopted on account of the existence in the 

 genus of an earlier descril)ed species of the same name.

Dark chocolate-red, with the head, legs and lower surfocc 

 black, the surface dull, except upon the inner anterior jxirt 

 of the elytra. Narrowly elongate, moderately convex, with 

 rather short anteim* and legs. The front angles of the head

 middle of the eve and the sides feebly prominent i)ehind the
