intervals extremely minutely, feebly punctulate ; scutellar impression very 

 feeble. Abdomen rather closely but feebly punctato-rugulose, with widely 

 scattered coarser punctures toward base, sparsely clothed with rather long 

 hair, denser laterally toward apex. Legs short and decidedly slender, very 

 sparsely pubescent. Length 5.8 mm. ; width 1.6 mm. 



Texas (Fort Worth). 



The slender cylindrical form, very arcuate beak, lateral vitta and 

 small size of this species are characters which will render it easily 

 identifyable. It is not closely comparable with any other known 

 to me. One specimen.

Pennsylvania — LeConte ; Iowa. The description of Say applies 

 almost completely to the species identified by LeConte as sylvius 

 Boh., and, as Boheman's description of sylvius will not answer at 

 all for this form, especially in the elongate form of the body, very 

 long beak and remote coarse variolate pronotal punctuation, there 

 can be but little doubt that the synonymy proposed is correct. 

 Marginatus is a small species ; rather robust and elliptical in 

 outline, with the vestiture sparse and more or less mottled above, 

 longer on the abdomen where it is very dense and conspicuous 

 along the lateral margins of the last three segments. The scutellar 

 impression of the elytra is large, deep and conspicuous, this char- 

 acter being especially alluded to by Say both in his diagnosis and 

 description. Length 6.7-8.2 mm. ; width 2.3-3.0 mm. 



11 I/, musculus Say. — Descr. of Cure, of N. Am., p. 14; punctinasus 

 Lee: Proc. Am. Phil. Soc, XV, p. 157. 



New Jersey to Texas and Colorado. Varies considerably in 

 size and somewhat also in the degree of acuteness of the elytral 

 apices. The form is rather stout and elongate-oval, moderately 

 shining, the prothorax short, transverse and more or less impressed 

 in the middle throughout the length, the vestiture short, not very 

 dense and more or less feebly mottled on the elytra. The type of 

 punctinasus is a small male of this species. Length 7.5-10.8 mm. ; 

 width 2.8-3.9 mm. 



12 L.. parcus Lee. — Proc. Am. Phil. Soc, XV, p. 157. 



California (San Francisco); not common. Resembles margin- 

 atus in its robust elliptical outline but is still shorter and broader,
