CALCODES. 207 



opaque at the sides, shining and finely unevenly jiunctured 

 in the middle. The sides are obtusely angular before tlie 

 middle, strongly and shar])ly behind the middle, and the hind 

 angles are sharj) but not produeed. The elytra are minutely 

 punctured and very glossy excej)t at the extreme outer margins 

 and apices, which are more strongly and closely ])unctured. 

 The lower surface of the body is rather smooth and shining. 

 The mentutn is coarsely rugose. 



(J. Rather narrowly elongate, dark brown, clothed with 

 rusty-yellow very fine setae, rather scanty u])on the sitles of the 

 head and jironotum, and close ujjon the elytra. The head is 

 not very broad, densely granular and opacjue, stiongly excised 

 at its front margin, with the front angles well marked but I)lunt, 

 the sides rather parallel in front and bearing a sharp spijiiform 

 })rocess behind the eye. The mandibles are of sim])le form, 

 fiat, not strongly curved nor widely separated. The pronotiun 

 also is densely granular, but a littk^ more feebly in its median 

 part. The front angles are very blunt, the sides very strongly 

 bilobed, the anterior lobe strong, the posterior one longer and 

 more spiniform. The hind angles are sharp. The elytra are 

 rather long and narrow, finely and rather clo.sely punctured but 

 sliining. The mention and suhmentMn are densely gianular. 

 The metchsternum is finely coriaceous and the abdomen well 

 pinictured. 



Variation of the male. Small males have the mandibles short, 

 with the imier edge entirely irregularly serrate. In medium- 

 sized exam})les there is a serrate basal lobe, and the terminal 

 half is also seri-ate and meets that of the other mandible. In 

 large specimens the mandibles are about twice as long as the 

 head, of similar form, but the serrate terminal part is only 

 about a quarter of the total length.

 dibles) 44-57 mm. : breadth, 2()-2-4 mm.
