204 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
This variety differs from the typical form (C. Bohemani) in colour—the elytra being 
nearly wholly black in the one, and with only the exterior oblique apical half in the 
other. It is considerably broader, and has (perhaps in consequence) more rows of striæ 
on the elytra, viz. about twenty-one instead of about fifteen, it is more convex, and it has 
the sides of the thorax a little more rounded. 
Found at Ega by Mr. Bates, and named after M. Candèze, of Liége, in token of admi- 
ration of his works on the larvee of Coleoptera, and more especially of his recent mono- 
graph of the family of Hlateride. 
The variety basalis resembles the typical form in colour, but is rather broader, flatter, 
more deeply punctate, and more pubescent. Bright testaceous red, with the apical half 
of the elytra piceous, the anterior margin of the piceous band indeterminate and 
irregular. Antenne rufous, with the club fuscous. Thorax with the posterior angles 
more projecting backwards. Scutellum thickly punctate. The elytra deeply punctate in 
rows, apex truncate, obliquely rounded, the pubescence fulvous on the black portion of 
the elytra as well as on the rufous part. Pygidium and abdominal segments less deeply 
and more finely punctate. 
Brought by Mr. Bates from Ega, and described from a single specimen in the British 
Museum. 
The above varieties may by some be considered distinct species. They hover on the 
borders between species and varieties, but they appear to me scarcely distinct. 
11. COLASTUS DORSALIS, 
Subdepressus, punctatus, levissime pubescens, supra niger, dorso rufo (videlicet thoracis 
medio, scutello, elytrorum medio et abdominis medio supra), subtus rufus; pedibus 
testaceis ; antennis testaceis, clava fusca; thorace angulis posticis rotundatis. Long. 
11 lin., lat. 4 lin. 
Habitat in Ega apud flumina Amazonum. 
Subdepressed, punctate, most feebly pubescent ; below testaceous red, above black, with 
a longitudinal oblong red patch reaching from nearly the anterior margin of the thorax 
to nearly the apical margin of the elytra and continued to the middle of the dorsal 
abdominal segments. Head moderately broad, closely but faintly punctate; mouth 
red; anteuns testaceous, with the club fuscous. Thorax short, transverse, gently 
rounded on the sides, narrowed in front, but not so much so as in many species; the 
base almost without sinuation, a little wider than the base of the elytra, posterior angles 
rounded ; punctuation very light on the disk, deeper and more frequent towards the sides. 
Scutellum red, slightly punctate at the base. Elytra slightly convex, more particularly 
towards the apex, for the most part gently punctate-striate, although in parts the stri- 
ation is interrupted and they are there only punctate in rows, faintest towards the suture ; 
the black space at the apex of the elytra enclosing the red dorsal patch is a little broader 
than that at the apex of the thorax. Abdomen above more pubescent and punctate; the 
red patch encroaches slightly on the anterior portion of the pygidium, but occupies a 
broad space on the penultimate segment. Underside testaceous red. Legs testaceous. 
From Ega on the Amazons. A single specimen in the British Museum.
