 legs reddish, anterior jiair lighter ; anterior tibiie finely but ratlier 

 imevenly and irrt>gularly toothed, the teeth being in some instances 

 fine and sharp, in others broader and blunter, the right and left tibiio 

 being occasionally diti'erent, and shoAving both these characteristics in 

 the same insect; both sexes have a small excavation at the extremity of

M. rotundicollis, Bris. Short oval, rather convex, leaden black ; 

 antennse light ; thorax about half as broad again as long, broadest about 

 the middle ; punctuation of thorax and elytra close, with fine but 

 distinct cross reticulation betAveen punctures ; in the two preceding 

 .S2)ecies the thorax is entirely smooth between punctures, and the elytra 

 are either smooth or show very faint traces of cross reticulation ; legs 

 reddish-yellow, anterior tibity finely denticulate. This species at iirst 

 sight closely resembles M. picipcs, and is often confounded with it ; 

 it is, however, readily distinguished from it liy the rounder and some- 

 what dilated sides of thorax, emarginate forehead, closer punctuation, 

 and also by the plain cross reticulation between the punctures of tlui 

 thorax and elytra, and the finer denticulation of the anterior tibiae.
