Very easily distinguishable from its allies by the char- 

 acters cited in the tabulation. The trilobed outline of the 

 head is very well developed, and is divided, the middle lobe 

 being about half of a lateral lobe in size. The punctures of 

 the pronotum are considerably smaller than those of the 

 elytra, but not conspicuously more closely or less closely 

 placed.
