Antenna- relatively shorter than in the preceding; the third joint 



at its apex a little broader than its length, narrowed towards the 



: the fourth joint nearly as long as the second and third taken 



• her, bul not wider than the second, narrowed at the basal half ; 



the following joints very gradually becoming narrower and a trifle 



er. Thorax not quite so short as in lietor, more rounded in 



trout, the posterior angles a little less diverging. Elytra rela- 



tivelv a trifle less long, the shoulders margined with dark reddish 



yellow. The coxa: and the extreme base of the femora yellowish. 



The species of this group are very variable, and it is difficult to 

 arrive at any definite conclusion as to the identity of the species 

 described by Newman with those of other authors. I think, how- 

 ever, that there is little doubt that alatus,TS., is the female of lietor, N., 

 corresponding respectively to timidas, Le C, and ceger, LeC, which, 

 according to Dr. Le Conte himself, are synonymous with modestua of 

 Sav (Bost. Journ., i. p. L53). See Le Conte, Journ. Ac. Phil. ser. 2, i. 

 p. 80, and List of the Coleopt. of X. Amer. p. 51. The reference in 

 Gemminger and v. Harold's 'Catalogue of Coleoptera,' p. 1634, 

 which assigns alatus to crenatus, Germ., is incorrect, as it is also 

 in the journal above quoted, at p. 79.
