30 Rev. H. S. Gorliam's materials for a 



Photinus concinnus, n. sp. 



Scarcely differs from pulchellus, but is rather smaller. 

 The thorax shows less traces of the rosy colour, and the 

 suture is of the same leaden colour as the rest of the 

 elytra ; their lateral margins are pale, but not beyond 

 three-quarters of their length.

Greyish-black, thorax of a beautiful blood-red, narrowly 

 and evenly margined Avith black, disc shining, with a 

 narrow black vitta scarcely touching the front or hind 

 margin, sides with distinct, scattered punctures and a 

 submarginal row, which become confused towards the 

 apex and hinder angles.

This very beautiM species is allied to the last, but the 

 thorax is rather longer, a little contracted at the hind 

 angles, which are acute, and is of a most beautiful gam- 

 boge-yellow ; the disc is a little uneven and irregularly 

 canaliculate in the centre, and is dark pitchy-black from 

 the base to about the middle, this dark portion being 

 widened at the base and nearly surrounded with bright 

 vermilion-red. The elytra are fuscous or leaden-black, 

 with but faint traces of raised nervures. The abdomen 

 is entirely black.
