yrijllivna mhmta, GraA-. 



L.c, %' lln. — 1-50-1 -7') mm. Fuscous black, clothed with 

 short grey pubescence, finely and closely tuberculate, head much 

 produced"^and attenuated in front ; mouth yellow ; thorax slightly 

 dilated at the base ; elytra not longer, but rather wider than the 

 thorax, abdomen shorter than the anterior parts united, obtusely 

 attenuated, apical and greater part of the penultimate segments 

 rufo-tostaceous ; legs and antenna? testaceous. 



Differs from the foregoing species in its minute size, longer 

 thorax, and shorter and stouter antennip. From M. ^^asoni it 

 may be known by its broader and longer thoi-ax and elytra, and 

 by its more depressed form. 



M. minnta seems to he in truth a rare insect. The greater 

 part of the supposed examples of this species pi-ove on examina- 

 tion to belong to 3f. mfnscata, but its long and dilated thorax 

 and long elytra, readily distinguish M. minnta from M . ivj'iiscdta. 

 in which the same parts are unusually short and nari'ow.
