not very unequal, and the fifth is but little longer than the fourth, so that 

 it is truly a Phytonomus. 



LEPYRUS Sch. 



The position of this genus seems to me to have been greatly misinter- 

 preted. Lacordaire has placed it next to Ilylobius, from whicli it differs 

 in the form of the mandibles which are emarginate simply, as in Phytono- 

 mus; in the size and shape of the mentum, which is oblong and rather 

 large; in the development of the ligula and palpi, which are much smaller 

 than in Ilylobius, and finally in the form of the articular surface of the 

 tibiae, which is in Lepyrus oblique, and in Hylobius and allies quite 

 lateral. 



In my opinion, Lepyrus is a gigantic Phytonomus, with scarcely any 

 generic characters to separate it, except the less transverse eyes and the 

 oblique terminal surfaces of the tibi;e. The habits of the species well 

 agree with this view, as thej^ are found on plants, or on the ground, 

 while the Hylobii occur only under bark. 

 Three species occur in our fauna.

 small narrow yellow scales instead of fine gray hairs, and also b}' the elytra 

 being separately acuminate at tip instead of conjointly rounded. 



LISTRONOTUS Jekel. Ann. Ent. Fr. 186i 565. 



This genus includes all the larger North American species heretofore 

 classed under Listroderes, and a few moderate sized or small species ; in 

 some of the latter the beak becomes cylindrical, and only feebly carinate, 

 so that they resemble in appearance Phytonomus. They are, however, 

 easily distinguished by the different proportions of the ventral segments ; 

 the first, second and fifth being long, and the third and fourth very short. 

 The legs are more slender than in Phytonomus, the tibiae bent inwards at
