to the species identified by Dr. LeConte as sylvius, this, as before 

 stated, being the same as marginatus Say. Length 6.8-9.1 mm. ; 

 width 1.9-3.0 mm. 



The dehiscent elytra, spoken of by Boheman, is an accidental 

 character, and among the specimens before me, I have one which 

 is similar to his type, also a specimen of laramiensis in which the 

 elytra become broadly dehiscent in apical fifth or sixth, that spe- 

 cies having, normally, only a very small sutural notch.

Virginia; Florida; Texas. This species greatly resembles the 

 preceding, especially in the very coarse variolate punctures and 

 constricted apex of the prothorax, and in size, but departs widely 

 in the much shorter and stouter beak. The beak in both sexes 

 is much shorter than the prothorax and is very much more robust 

 and coarsely punctured than in sylvius. Length 6.5-9.5 mm. ; 

 width 1.9-3.0 mm.

California (Lake Co., San Francisco, Tehachapi Pass and Yuma)-. 

 A rather slender species, closely resembling the two preceding in 

 size and many other more important characters. The beak is slen- 

 der, equal in length to the prothorax in the female and a little 

 shorter in the male. There is a distinctly marked tumid or um- 

 bonate spot on the disk of each elytron near apical fifth. The three 

 specimens from Yuma are rather larger than those from the coast 

 regions and probably indicate a varietal form with still longer beak. 

 Length 6.8-10.3 mm. ; width 1.9-2.8 mm. 



23 L<. semivittatus n. sp. — Parallel, convex, moderately slender, black 

 throughout, the antenna? scarcely paler, the elytra feebly shining through the 

 dense vestiture which is rather long and pubiform, forming three vittae on each, 

 the narrow vitta of the third interval always distinct throughout the length, 

 joining the broad submarginal vitta at apical sixth, the vitta on the fifth inter- 

 val often very feebly defined. Head transversely but very feebly impressed 

 between the eyes ; beak toward base and the head coarsely, sparsely punc- 

 tate, the former rather robust, about three-fourths as long as the prothorax 

 in the female and still shorter in the male, very feebly arcuate; antennae in 

 both sexes inserted at about the middle. Prothorax almost as long as wide, 

 subquadrate ; sides parallel and feebly arcuate, very strongly and abruptly
