DORCUS. 157 



long, each of the four posterior tibiae armed with a lateral spine. 

 The prosternum rounded behind the front coxae, not pointed 

 nor djstmctly compressed. 



$. The head is uneven, coarsely rugose in front and strongly 

 pimctured behind, except in the middle. The canthus is bluntly 

 prominent at the middle of each eye. The mandibles are 

 hollowed above and strongly and closely punctured and each 

 has a blunt tooth near tlic middle beneath. The pronotinn is 

 very smooth and shining, witli minute scattered ])unctures, 

 except at the sides, which arc coaisely and rugosely punctured. 

 The front angles are very blunt, the sides feebty curved to 

 beyond the middle, where there is a rather sharp angle, and the 

 iiind angles are completely romided. The elytra arc^ finely and 

 fairly closely punctured but very sliining dorsally and densely 

 punctured and Hubf)paque at the sides. The front tibia, is lung 

 and slender, with tlie outer edge finely serrate and with a few 

 small sharp teeth, the termmal part produced and slightly 

 curved, widely forked, with fine teeth upon the outer branch of 

 the fork. 



(J. The head is finely coriaceous and opaque, with strong, 

 rather scattered, punctures at the sides. The sloping anterior 

 part is deeply hollowed in the middle, the anterior angles 

 laterally produced in front of the eyes, but not very acute. 

 The cantlius extends to al)out the middle of the eye and tiie 

 sides of the head are nearly straight and jiarallel l)eliind. Tlu; 

 clvqical process is 3-lobed, the median lobe a little ])roduccd. 

 The pronotunt is short and broad, very smooth and shining in 

 tlie middle, didl and coriaceous at the sides and rugosely 

 jnmctured near the lateral margins. The front angles are 

 blmitly produced, the lateral margins feebly curved to beyond 

 the middle, where there is a minute sharp angle. The hind 

 angle is very broadly rounded. The elytra are very smootli 

 and shining dorsally, with punctures which are minute and 

 scanty near the suture but become gradually stronger and 

 closer towards the sides, the outer margins being rugose and 

 o]m(|ue, at least in the ])osterior part. The front tibia bears 

 mmute scattered lateral teeth. 



Variatio7i of the male. In a ratlier small specimen the front 

 angles of the head are blunt, the sides of the head, thorax and 

 elv'tra are rugose and the mandibles short, with small teeth. 

 })la(>ed not far apart. In the larger t^q^e-s})ecimen the front 

 anglesof the head are sharper, the mandil)les are a little louL^cr 

 tlian the head and each has a strong, ratluM- shar}) horizontal 

 tooth internally dose to tlie base, a shorter one at al)ont two- 

 thirds of till' length from the base, and a minute one between 

 tlie last and the ajiex.
