 A. Sulci antennarii prothoracis brevissimi. 

 a. Frons deflexa.

^ A. The eyes granulated; posterior comers of the pronotum with short 

 dorsal ridge ; hind feet not longer than tibiae ; hairy covering of antennae 

 the same in both sexes {M. niger, M. brunnipes). B. Eyes smooth, the 

 ridge on the hind corners of pronotum continued forwards along the sides; 

 hind feet longer than tibiae ; antennae of male woolly underneath {M. cas- 

 tanipes). Prof. Schiodte does not admit Cratonychus rufipes, Erichs. 

 (Germar, Zeits. iii. 96. 8) as a species distinct from M. castanipes, Payk., 

 and states that E. bicolor, Fabr., is a very different, southern species.
