excavated than in the former, the two antennal ridges are shorter, the 

 vertical one is altogether obsolete. The palpi are robust. The 3rd 

 antennal joint is about one third longer than the 4th. The thorax 

 is shorter and plumper than in the former. The elytra are less 

 oval, having the shoulders more prominent and only the apex rounded 

 off" or narrowed. The legs are similar to those of the former, but 

 more robust, less hairy and have the tarsi more cylindric. The in- 

 sect is of a blackish metalic colour ; the legs and palpi are yellowish ; 

 the tibiae, however, the apex of the palpi, and also joints 1-2 of the 

 antennae are rather darker ; the femora are blackish towards the end ; 

 the mouth and joints 3-11 of the antennae are chestnut and the coxa? 

 pitch-colour. The animal is densely and deeply punctured all over, 

 very sparingly covered with small greyish hairs, nearly obsolete on 

 the back but more distinct below. It is less highly polished than 

 the former. I have known this species for a long time, and speci- 

 mens of it must exist at the Mus. Berol. ; the former I met with 

 but lately. 



I may mention that in dissecting these two species I have 

 observed the same remarkable production of the oesophagus with 

 the ligula, characteristic of the g. and noticed in many of the Euro- 

 pean kinds.

This insect looks uncommonly like an ant. It is easily distin- 

 guished from all other species of the Island partly by this resem- 

 blance, partly by the sculpture of the thorax and the white fascia 

 across the elytra. The antennae are robust, thickened towards the 

 tip, the 3 last joints forming a club. The legs have the femora very 

 much incrassated, the tibiae at the apex bicalcarate and the tarsi r
