DORCUS. 10] 



strongly punctured at the sides, witli tlie lateral margins 

 rounded and not angulate and the front angles produced. 

 Tlic sides of the elytra are closely junictured but not opaque. 

 The front tibia is very broadly and shortly fork(!d at the end 

 and the middle and iiind tibiu' have each a miiuite spine. 



(^. Thv head is broad, flat and entirely ojjaque, with the 

 eyes ratiier prominent and tlie sides of the iiead very obtusely 

 angulate in front of tliem and convergent behind. The cl_yj)eal 

 process is broad, its front margin nearly straight and the 

 angles sharply produced. The pro7iotum is very short and 

 broad, very opaque at the sides and a little less so in the middle. 

 The front angles are bluntly ])roduced, the sides rounded and 

 bluntly toothed far behind the middle. The i^cutelhim is 

 opaque. The elytra are extremely glossy, with the outer 

 margins coriaceous and o])aque. The front tibia is finely 

 serrate externally, with small scattered su])plementary teeth, 

 and the terminal fork is short. The middle tibia has usually 

 a minute lateral spine and the hind tibia is without one. 



Variation of the male. In small specimens the mandibles 

 are shorter than the head and each has a broad serrate lamina 

 equidistant from the base and ti]). The tip is simple and 

 sluirp. Full-sized males have the head broader, the mandibles 

 from l\ times to twice the length of the head, flat, of nearly 

 uniform breadth, gently and uniformly curved, with a small 

 tooth just before the tij) and a small j^rocess ending in two or 

 three cusps a little behind the tooth. 1 have not seen any 

 intermediate condition.

Black, with a curvilinear orange streak just before the 

 extremity of each elytron, the two streaks sometimes almost 

 meeting at the suture, forming a semicircle, but sometimes 

 much reduced, the femora orange -coloured beneath, except 

 at the base and apex. Rather narrowly elongate and not 

 very convex, with the elytra extremely smooth and shining 

 dorsally, with broad opaque outer margins 8har[)ly separated
