480 COLEOPTERA OF NORTH AMERICA. 



differ by the hind angles being prominent, and more or less pro- 

 duced over the base of the elytra. 



The beak is slender, cylindrical, as long as the prothorax; the 

 antennal grooves reach the lower edge of the eyes which are 

 rounded and distant from the prothorax. Antennae inserted near 

 the tip (Z), or about the middle of the beak 9, slender, feebly 

 geniculated; scape slender, slightly clavate, curved near the end, 

 and usually attaining the eyes. Front coxae contiguous, promi- 

 nent;. middle coxaj not widely separated; hind coxffi not very 

 distant, small, oval, not extending to the elytral margin. Side 

 pieces of mesothorax rather large, obliquely divided. Metaster- 

 num long, episterna rather wide; epimera visible behind, ventral 

 segments unequal, first and second long, connate, with a faint 

 undulated suture; intercoxal process acute; segments 3-5 short, 

 equal. Elytra oblong, not convex, widely separated at base by 

 the scutellum, separately rounded at tip, exposing part of the 

 pygidiiim. Legs moderate, thighs not clavate, sometimes toothed, 

 tibiae strongly unguiculate at tip; tarsi spongy beneath, third joint 

 broader, bilobed ; claws sometimes simple, sometimes toothed. 



Magdalis extends across the continent. 



Tribe IX.— ANTHO]¥OMI!VI. 



This tribe is represented by a large number of species of small 

 size, and contains but few genera. 



They may be distinguished by the following assemblage of 

 characters : — 



Mandibles normal in form, gular peduncle long, mentum and 

 ligular small. Beak long, slender, cylindrical; antennal grooves 

 extending to the lower edge of the eyes, which are small, convex, 

 rounded, and distant from the prothorax, widely separated above, 

 except in Orchestes, and a few species of Anthonomus. Antennae 

 inserted far from the tip of the beak, slender, scape long, funicle 

 6- or 7-jointed ; club elongate-oval, pointed, entirely pubescent, 

 and sensitive, very distinctly annulated, sometimes almost articu- 

 lated or divided into separate joints. Prothorax without post- 

 ocular lobes, prosternum very short, not emarginate in front, 

 cox8e contiguous, prominent. Mesosternum separating moder- 

 ately the coxae; side pieces diagonally divided. Metasternum 

 moderately long, side pieces narrow, ventral segments separated
