120 CUKCIJLIONID^.. 



[lioConte. 



LOPHALOPHUS n. g. 



In this genus the beak is parallel, flat above, not as stout as in the other 

 genera, and the apical wings are not developed; the medial groove is re- 

 placed by a fine carina, and the lateral grooves are wanting ; the antennal 

 grooves are short, oblique as usual, but becoming wide and obliterated be- 

 hind; the grooves on the under surface are obsolete. The antennae are as 

 in Alophus, but rather thicker; the seccmd joint of the funiculus, as usual, 

 a little longer than the first. The eyes are scarcely transverse, but dis- 

 tinctly angulated below; the postocular lobes are obsolete, and the pro- 

 sternal transverse impression scarcely extends on the sides. The elytra and 

 head are finely punctured, and the former has distinct rows of larger punc- 

 tures; the prothorax is coarsely and densely punctured, not channeled, but 

 with a small, dorsal smooth space. Under surface pubescent. 



The only species known to me is 



Li. inquinatus. Liophlosus inq. Mann., Bull. Mosc. 1852, 351. 



Alaska ; two specimens from Baron Chaudoir. Difters from LiopMc&us 

 by the mandibles being without apical scar, by the maxillae not covered by 

 the mentum, and by the ungues being separate, not connate at base. 

 Length 5.5 mm.; .22 inch. 



LBPIDOPHORUS Kirby. 



Tliis genus is easily distinguished from the others of the sub-family by 

 the beak being a little broader at the tip, with feeble wings, somewhat as in 

 Alophun; otherwise, it is cylindrical, and not carinate nor grooved; the an- 

 tennal grooves are broad and short, directed towards the eyes, which are 

 scarcely transverse, and distinctly angulated below. The scape of the an- 

 tennae is longer than in the other genera, extending across the eyes; the first 

 joint of the funiculus is as long as the three following united; 2-7 equal in 

 length, gradually a little thicker; club oval, pointed. Prothorax not lobed 

 in front, only obsoletely impressed at the sides near the tip; rounded on 

 the sides in front, not narrowed behind, scarcely as wide as long. Elytra 

 elongate oval, humeri rounded; striae well marked, interspaces flat. Front 

 and middle tibi* slightly curved and mucronate at tip; the hind pair 

 scarcely mucronate, truncate at tip. 



1. L. linsaticollis Kirby, Faun. Bor. Am. iv. 201 ; Schon. Cure, vi, 

 2d, 25G; Mann. Bull. Mosc. 1853, 243. 



Two specimens from Alaska, not very well preserved. The body is 

 densely clothed with scales and small bristles; the latter arranged in series 

 on the elytra. Length 4.5 mm.; .18 inch. 



Tins is perhaps Phytonomui trioittatun Say, Cure. p. 12; ed. Lee. i, 278; 

 but the description is not very definite. 



Sub Family IIL ITHYCERIDJE. 



This sub-family is represented by a single species, and is Avell dis- 

 tinguished from all other Curculionidje by the following assemblage of 

 characters.
