and a little backwards towards the apex, and by the ex- 

 tremely long claw-joint of the tarsi ; the third joint of 

 the antennge is nearly as long as the four following taken 

 together, and is thickened and cylindrical.

1. Polyoza lineata, n. sp. 



P. oblongo-linearis, rufo-fulva, elytris utrinque sutura 

 et carinis quatuor elevatis, interstitiis nigris : an- 

 tennis ( J" ) dimidium corporis vix superantibus, arti- 

 culis 3 — 8 basi laminas elongatas emittentibus. 



Long. 11 lin. (c?). 



Resembles in form P. Lacordairei ; the head, palpi, 

 mandibles, and eyes offer scarcely any difference : the 

 thorax has on each side three teeth, the foremost one 

 very small, and the hindmost pointing towards the 

 shoulders of the elytra ; its surface is sculptured in a 

 raised reticulate pattern. The elytra offer a raised 

 suture and four carinas, the interstices of which are of a 

 dark colour, the whole surface is finely rugose-punctate, 

 and the sutural angle acute, but not spinose. The an- 

 tennae are very much shorter than in P. Lacordairei, and 

 the long foliaceous appendages to the joints placed more 

 closely together. The underface and legs are finely 

 punctate-granulate and hairy, and of a paler hue. 



One example, taken in a dead tree at Ega.
