Coleopterological Notices, V. 599 



In CentrivKS acuminatus and glohifer (1. c, pp. 404, 591), the 

 t<ioth referred to as belonging to the trochanters, really projects from 

 ihe femora very near the trochanters. 



Ceiitrinus nvbecula Csy. (1. c, p. 594), must be regarded as a 

 hirge female of capilfatvs, and Centrinopus helvinus (p. 602), is to 

 lie placed in synonymy with alternatus, the latter being the name 

 of the species. A series recently sent to me plainly unites these 

 two forms, the latter of which was founded upon a specimen stand- 

 ing at one of the extremes, both in size and ornamentation, of a 

 verv variable species. In Calavdrivvs iTnaignis the elytra are 

 relatively shorter and paler than in granaicoUis, the striae coarser, 

 the intervals narrower and subequal, each with a single line of 

 ])unctures, the four lateral spots of white scales well defined with 

 scarcely any scattered pale scales. 



The species which I regarded as the Centrinvs canus of LeConte, 

 liecause of its extended distribution under that name, proves to 

 be quite different, and this will account for the apparent discrepancy 

 in the original description.^ The true canus is the form, a specimen 

 of which was compared, on page 646, with LimnohaiHs longula. It 

 is allied rather closely to lovgula, but is a larger and broader spe- 

 cies. The description of LeConte will probably prove sufficient for 

 its recognition, and is from a female type, the beak in that sex 

 being rather slender, smooth, polished, subimpunctate except near^ 

 the base and as long as the head and prothorax ; in my male speci- 

 men the beak is shorter thicker and coarsely sculptured, as described 

 on the page referred to. The species is therefore to be placed imme- 

 diately after Limnobai-is longula with the following references: —

There is a large series of this species in the cabinet of Mr. Ulke. 

 The form identified by me as canus and placed in the genus Nicen- 

 trns, must receive another name as follows: — 



NicenfrilS grosslllllS n. n. — A'^. canus Csy. nee Lee. : Ann. N. Y. Acad. 

 Sci., VI, p. 614. 



The series in my cabinet now consists of eight specimens, vary- 

 ing in length from 4 to 5 mm., but otherwise quite homogeneous. 

 The vestiture is generally more yellowish than whitish. 



' This is the only speeies not described from the original type or a specimen 

 carefully compared therewith.
