L.eConte.1 



ANTHONOMINI. 209 



closely connected, gradually wider, and uniting with the annulated club 

 so as to form a regular club shaped outline. The beak is cylindrical, rather 

 stout, about as long as the prothorax; antennae inserted one-fourth from 

 the end; eyes large, transversely oval; front narrower than the beak. Pro- 

 thorax wider than long, narrowed in front, broadly rounded on the sides ; 

 prosternum short, emarginate in front. Elytra elongate, wider than pro- 

 thorax; humeral angles rounded, sides parallel, striae obsolete. Ventral 

 segments nearly equal, third and fourth very little shorter, sutures straight, 

 less deeply impressed than in Anthonomus. Legs rather short, front thighs 

 armed with a large tooth, other thighs unarmed, sub-clavate; tibiae straight, 

 obliquely truncate, without terminal hook ; claws with a slender tooth, as 

 in most Anthonomus. 



1. M. estriatus, n. sp. 



Elongate, black, not very densely covered with elongate cinereous scales; 

 beak densely finely punctured, separated from the front by a feeble trans- 

 verse impression ; head punctured; prothorax more deeply and coarsely 

 punctured; elytra densely punctured, with slight traces of stria? near the 

 margin and tip ; front thighs strongly toothed; antennae brown, with ver- 

 ticellate rows of white scales. Length 2.7 mm. ; .10 inch.

When the scales are rubbed off a fine inconspicuous pubescence remains. 

 The emargination of the prosternum gives an appearance of feeble post- 

 ocular lobes, and in following Lacordaire's arrangement this genus would 

 be placed in the Ceratopides, after AcantTiobrachium, from which it seems- 

 to differ by having only the front thighs toothed.

I have separated as a distinct genus ErirMnus ephippiatus Say, which 

 differs from the other genera of this group by having the last ventral seg- 

 ment as long as the two preceding, and the claws divergent and broadly 

 appendiculate . The beak is not very slender, cylindrical, as long as the 

 prothorax ; the antenna? are inserted about one fourth from the end ; the 

 scape attains the eyes, which are rounded, moderate in size, and distent ; 

 funiculus 7 -jointed, first joint stouter and longer, the others equal, gradu- 

 ally a little wider, the outer ones rounded ; club elongate-oval, annulated. 

 Prothorax wider than long, narrowed in front of the middle, rounded on 

 the sides, feebly constricted near the tip. Elytra wider than prothorax, 

 oblong-elongate, humeri rounded, sides parallel, striae punctured, inter- 

 spaces nearly flat. Prosternum short in front of the coxae. Ventral su- 

 tures straight, third and fourth segments united equal to each of the others, 

 fifth flat, with a very small apical carina in one sex. Legs moderate, 

 thighs feebly clavate, not toothed, tibiae with a distinct terminal hook, 

 tarsi dilated, third joint very broad, bilobed; claws divergent, with a broad 

 rectangular tooth or appendiculum.
