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 ; 

 presternum short, emarginate in front. E]}'tra 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 ^pressed than in Anthonomus. Legs rather short, front thighs 

 armedwitlia large tooth, other tliighs unarmed, sub-clavate; tibiae straight, 

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

 in most Antho7iomus. 



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 striae near the 

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

 ticellate rows of white scales. Length 3.7 mm. ; .10 inch.

When the scales are rubbed oft" 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 AcanthobracMum, from which it seems 

 to differ by having only the front thighs toothed.

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

 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 antennae are inserted about one fourth from the end ; the 

 scape attaijj^ the eyes, whicli are rounded, moderate in size, and distant ; 

 funiculus Tsjointed, 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 i^rothorax, 

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

 si)aces 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, 

 thiglis 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.
