280 MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 
sides as in C. adustus. Oblong, somewhat convex, shining, almost glabrous, rufous. 
Head coarsely punctate, with the middle a little darker. Thorax more sparsely punctate, 
a little narrower in front, with the apex emarginate and the sides subparallel,—very 
little rounded, scarcely broader than the elytra, and all the angles obtuse and slightly 
rounded. Scutellum rounded at the apex, dark chestnut, closely punctate at the base, 
smooth at the apex, and with a longitudinal fuscescent marking on the disk. Elytra black 
or nigro-piceous, except a narrow oblique rufous patch parallel to the sides of the scu- 
tellum, the suture black; coarsely punctate, the punctures running into rows, which 
towards the suture become almost punctate strive; hollowed along the suture, wider 
behind than in front, the apex of each elytron obliquely rounded, sutural angles obtuse, 
exterior apical angles rounded. Abdomen above longitudinally marked with a fuscous 
indeterminate patch, thickly and more finely punctate than the rest of the surface, finely 
fulvo-pubescent. 
From Brazil. 
40. COLASTUS FERRUGINEUS. | 
Depressus, planus, oblongus, nitidus, testaceo-ferrugineus, leviter pilosellus ; capite et 
thorace fortiter punctatis, elytris seriatim punctatis. Long. 2 lin., lat. 2 lin. 
Habitat in Brasilia. 
Flat, depressed, oblong, morethan twice as long as broad, shining, testaceo-ferruginous, 
sparingly pubescent, hairs reddish. Antenne of the same colour, with the club fuscescent. 
Head coarsely punctured. Thorax short, nearly twice as broad as long, truncate at the 
base, emarginate in front; sides rounded from behind to the front, which is a good deal 
narrower than the base; coarsely punctured. Scutellum punctured across the base, 
smooth at the apex. Elytra longer than the thorax, but not quite so long as the head and 
thorax taken together, inclined towards the suture, becoming insensibly darker towards 
the apex, rather deeply punctate, the punctures arranged in rows, the punctuation not 
so coarse as that on the thorax; the pubescence arranged in rows. Underside and legs 
testaceo-ferruginous. The last two segments of the abdomen moderately punctate, the 
preceding segment very finely punctate, the remainder not punctate. 
From Brazil. 
41. COLASTUS STRIATICOLLIS. 
C. infimo paulo minor: planus, depressus, nitidus, testaceus; capite punctato ; 
thorace transverso, quadrangulari, disco planato striis quatuor 8 
longitudinalibus, lateribus irregulariter punctatis; scutello punctato; ely- 
tris striato-punctatis, interstitiis haud punctatis. Long. 4 lin., lat. 4 lin. 
Habitat in Brasilia. 
About the size of C. infimus, but not allied to it. It is so shining and so nearly 
glabrous, that the pubescence can only be seen by a powerful glass. It is flat, depressed, 
and testaceous; the legs and underside somewhat paler. Head punctate. Thorax trans- 
verse, quadrangular, all the angles nearly right angles; the sides very little rounded,
