474 COLEOPTERA OF NORTH AMERICA. 



to the Erirliini proper, and like them have the antennal grooves 

 directed against the eyes; they differ iti having the eyes larger 

 and more prominent, and separated from the margin of the pro- 

 thorax by the head being more or less prolonged behind. The 

 head thus recalls the form already seen in Rhinomacer and Rhyn- 

 chites, though otherwise there is no resemblance. 



The two species known to us resemble in appearance small 

 Dorytomus but the thighs are unarmed, and the second joint of 

 the fuhicle of the antennas is short. 



They may be for the present referred to the genus Phyllotrox, 

 though they differ from the description given by Lacordaire (Geu. 

 Col. vi. 505), by the first ventral suture being well marked. One 

 is Califoruiau, the other from Florida. 



Gioiip IV. — Cryptopli. 



In this group the body is densely clothed with scales, forming 

 usually a shining crust ; the beak is cylindrical and curved, not 

 separated from the head by a transverse impression; the antennal 

 grooves commence about one-third from the end, and run directly 

 towards the eyes which are lateral, oval, transverse, coarsely 

 granulated, and not approximate beneath. Funiculus of the 

 antennae in some genera 6-jointed ; first joint long, the others 

 short, increasing gradually in breadth, and sometimes passing 

 insensibly into the club, which is rather large, oval, annulated, 

 and pubescent. Prothorax with broad postocular lobes, front 

 coxse large, prominent, contiguous, prosternum transversely, very 

 deeply impressed but not excavated in front of the coxae, or deeply 

 emarginate. The legs are not very slender, the thighs moderately 

 clavate, the tibia; sinuate on the inner side, as long as the thighs, 

 truncate and mucronate at tip, with the articular surface terminal; 

 the front tibiae subserrate from the middle to the tip. Tarsi broad 

 with the fourth joint short, variable in form (absent in the Euro- 

 pean Anoplus), third joint broad, deeply bilobed. Elytra with 

 ten entire striae. 



Last joint of tarsi broad, claws distant. 



Last joint of tarsi narrow, with one claw. Brachybamus, 



Last joint of tarsi narrow, projecting, with two slender claws. Onychylis. 

 Elytra slightly wider than the prothorax. Endalus. 



Elytra much wider than the prothorax. Tanysphyrus.
