DESMONYX. 361 



most one very blunt and the others long and sharp. Near its 

 articulation with the femur it is rather abruptly narrowed, leaving 

 a projection which interlocks with the femur. The four posterior 

 tibiae are very spinose externally and clothed with verv long hairs. 

 The tarsi are rather slender, and the claws long and slender, those 

 of the four posterior feet simple and equal. 



The front tarsi of the male are rather thickened, the penultimate 

 joint has a lobe beneath, and the claws are unequal, the inner one 

 very widely cleft and its lower branch broad. 



Only a single species is known.

Dark mahogany-brown, with the back of the head, the middle 

 of the prothorax, the scutellum and the anterior part of the elytra, 

 as well as the club of the antenna, black, and with two yellow spots 

 near the anterior border of each elytron one near the scutellum, 

 and a rather smaller one a little behind and outside the first. 



It is a small, shortly ovate insect, com- 

 pactly built, with the entire surface, 

 except the dorsal part of the elytra, 

 clothed, although not very thickly, with 

 erect hair. The upper surface is coarsely 

 and rugosely punctured. The clypeus is 

 finely rugose, broad and trilobed in front, 

 strongly constricted at the base of the 

 antennae. The prothorax is coarsely punc- 

 tured, channelled along the middle, broadly 

 rounded at the base, with the front angles 

 acute and the hind angles rounded. The 

 scutellum is nearly semicircular and finely 

 punctured. The elytra are coarsely punc- 

 tate-striate, with the intervals rugose. 

 The pygidium is minutely punctured and shining. 



c?. The antennal club is very long; the last joint of the front 

 tarsus is enlarged, the inner claw thickened and very widely cleft, 

 and the fourth joint produced beneath the claw-joint ; the other 

 claws are simple, slender and equal.
