and rostrum, the rostrum being received in a very deep parallel-sided cavity in 
the prosternum, as in Cnagius. Colonertus, according to Solari, approaches the 
‘‘ Nertides” of Lacordaire in its subcylindrical form and visible, depressed meso- 
sternum ; it seems to me, however, best placed amongst the ‘“‘ Centrinides” for the 
present, near Cnagius and Coluthus. 
1. Celonertus nigrirostris. (Cylindrobaris brevirostris, Tab. XVII. figg. 19, 
19a, b, 3.) 
Colonertus nigrirostris, Solari, Ann. Mus. Genova, xlii. p. 4427. 
Black or nigro-piceous; above somewhat thickly clothed with narrow white or whitish scales, the elytra 
with a sinuous transverse blackish fascia of variable extent below the base (reaching inward to the 
first stria), the vestiture of the prothorax sometimes coarser and more condensed along the sides and 
middle in the ¢, that of the elytra arranged in one or two rows (widening to two or three at the base) 
down each interstice ; the legs and under surface also albo-squamose, the vestiture becoming denser on the 
metathoracic episterna. Head closely punctate, the eyes well-separated ; rostrum in the ¢ very short, 
scarcely longer than the head as seen in profile, closely striato-punctate, that of the Q a little longer 
and smoother. Prothorax nearly as long as broad, rounded at the sides anteriorly, not or feebly 
constricted in front; densely, somewhat coarsely punctate. Elytra moderately long, slightly wider than 
the prothorax, conjointly rounded at the apex ; finely punctate-striate, the interstices rugulosely punctate. 
Beneath densely punctate. 
Var. The transverse dark fascia of the elytra obsolete, the vestiture arranged in a single line down each 
interstice ; the punctures on the prothorax each bearing an oval white scale. (¢.)

Ten specimens, varying greatly in size and in the extent of the vestiture of the 
upper surface, but probably all belonging to one variable species. The variety is 
represented by a single very small male: all the forms were found at Belize. ‘The 
type has been kindly communicated by Signor Solari for comparison.

Barilepton, Leconte, Proc. Am. Phil. Soc. xv. p. 818 (1876) ; Casey, Ann. N. York Acad. Sci. vi. 
pp. 469, 675 (1892). 
Casey recognizes four N.-American species of this genus, and the Mexican 
representative now recorded is so closely related to one of them that it cannot be 
satisfactorily separated. They are very small, cylindrical forms, with a short, stout, 
arcuate rostrum, long elytra, and single tarsal claws.
