Coleopterological Notices, V. 599 



In Centrinus acuminatus and glohifer (1. c, pp. 464, 591), the 

 tooth referred to as .belonging to the trochanters, really projects from 

 the femora very near the trochanters. 



Cevtrinus nvbecida Csy. (1. c, p. 594), must be regarded as a 

 large female of capil/atvs, and Centrinopus helvinus (p. 602), is to 

 he 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 w^as founded upon a specimen stand- 

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

 very variable species. In Calandrwvs ivsignis the elytra are 

 relatively shorter and paler than in granaicollii<, the striae coarser, 

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

 punctures, the four lateral spots of white scales well defined with 

 scarcely any scattered pale scales. 



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

 because 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 Limnobaris longula. It 

 is allied rather closely to longula, 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 Limnobaris longula with the following references: — 



L.illliio1)aris cana Lee. — Proc. Am. Phil. Soc , XV, p. 421 (Centrinus) ; 

 longula var. Casey : Ann. N. Y. Acad. Sci., VI, p. 646. 



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

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

 trus, must receive another name as follows : — 



JVicenfrus grossullis n. n.—N. cams 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 species not described from the original type or a specimen 

 earefully compared therewith.
