tenn black, with the last article testaceous. The head thickly and strongly punctate, 
black, shining, sparingly fulvo-pilose. Thorax truncate at the base, with the sides 
gently rounded, thickly and strongly punctate, with a longitudinal slightly raised smooth 
line in the middle, fulvo-pilose, with a large black patch occupying the disk and anterior 
margin both above and below. Scutellum thickly punctate. Elytra somewhat longer 
than the thorax, punctate in rows, densely clothed with a longish suberect pubescence, 
with the exterior margin towards the apex narrowly coloured piceous or black. Abdomen 
lightly punctate, fulvo-villose. Metasternum with a triangular black patch, sparsely 
punctate. 
A fine, large, and distinct species—the largest of the genus. 
From Cayenne. There is one specimen in the Berlin collection, and a pair in Dejean’s 
collection in the possession of the Marquis de la Ferté, where they stand under the name 
of Strongylus maculicollis, Buq.

Oblong, slightly convex, shining, almost glabrous. Antenne rather short, testaceous, 
club fuscescent. Head thickly and strongly punctate, rufous; with a piceous spot in the 
middle. Thorax subquadrate, truncate at the base, rather narrowed in front, with the 
sides nearly parallel and scarcely rounded, the posterior angles somewhat obtuse, trans- 
verse, slightly convex, sparsely and strongly punctate, rufous, with the disk becoming 
piceous in the middle, not broader than the elytra. Scutellum sparingly punctate,

39. CoLASTUS DECORUS. 
Leviter convexus, punctatus, subnitidus, rufus ; elytris seriatim punctatis, nigris, macula

liter fuscescente. Long. 2 lin., lat. $ lin. 
Habitat in Brasilia. 
Closely allied to C. adustus, Erichs., but more coarsely and more closely punctate, and 
consequently not so smooth and shining; the colour darkest on the disk, and not on the
