 an appearance as of three feeble tubercles between antennfe. 

 Antennse extending beyond elytral fascia, 1st joint curved, the

 2nd. Prothorax about once and one-third wider than long, sides 

 narrowly margined and feebly incurved to near base; indistinctly

In the tabulation this species would fall beside picticoUis, 

 Blackburn, from which it differs in the depth of its colour, but 

 especially by its very much coarser elytral puncturation. In five 

 specimens under examination three have the prothorax immacu-

 of its prothorax and under surface, length of antenna?, (fee,
