1874.] 275 [LeConte. 



The characters therefore are : Body elongate, finely punctured, 

 clothed with fine prostrate pubescence; head rather small, eyes con- 

 vex prominent, transverse, rather finely granulated; mandibles bifid 

 at tip; maxillary palpi moderately long, last joint wider than second 

 and third, triangular; antennae slender, longer than head and protho- 

 rax; second joint a little shorter than third. Prothorax narrowed in 

 front, rounded on sides, feebly bisinuate and finely margined at base. 

 Elytra parallel, gradually rounded and narrowed behind. Legs short, 

 feeble, tarsi slender, penultimate joint bilobed, first joint of hind 

 tarsi as long as the others united. 



A second species of this genus is indicated by a specimen from 

 Oregon, too mutilated to permit of generic determination in my 

 former investigations. It is in form and size similar to the species 

 above described, but differs by the prothorax more distinctly bisinuate 

 behind, the hind angles better defined, and by the antennas being 

 testaceous at base, and at the extremity of the last joint. It may be 

 called S. basalis. 



Cephaloon ungulare sp. nov." 



Very elongate, testaceous or piceous, finely punctured and pubes- 

 cent; antennae slender, scarcely thickened externally, joints 9-11 

 longer, especially in the <?, claws pectinate, with the appendage 

 slender, curved and acute at tip. Length 11-13 mm. ; .44-.50 inch. 



White Mountains and Lake Superior : resembles in form C. leptu- 

 rides, but is more slender, with the antennae longer and nearly fili- 

 form; the claws are rather stout, and strongly pectinate as in that 

 species, but the appendage is slender, curved and acute at tip, as in 

 most Meloides. 



I received from the Rev. A. Matthews a specimen collected in 

 Vancouver's Island, which, on more careful examination, proves to be 

 quite distinct; it maybe known by the following characters: — 



C. tenuicorne sp. nov. 



Above testaceous, head behind the antennae, sides of elytra and 

 under surface piceous; antennae a little longer than the head and 

 prothorax ; (cf ) slender, slightly thickened externally, joints 3-7 

 slender, elongated (third longest), ninth and tenth shorter than 

 eighth, wider than the preceding ones, eleventh nearly twice as lono- 

 as the tenth. Length 12 mm.; .48 inch. 



The appendage of the claws in this species is broad and rounded 

 at tip, precisely as in C. lepturides ; the form is also broader and 

 stouter, resembling the figure of the Siberian C. varidbile Motsch.
