29. COLASTUS ATER. 
Oblongo-ovatus, depressus, nitidus, niger, pube longa parce vestitus, fortiter Fig. 40. 
punctatus; thorace basi bisinuato; elytris subseriatim crebre punctatis ; 
pygidio basi punctato, apice levi et elevato; ore tarsisque piceis. Long. si 
2 lin., lat. 1 lin. 
Habitat in Venezuela. 
Closely allied to C. simplex. Oblong-ovate, depressed, twice as long as broad, shining, 
very black, and clothed with a long stiff pubescence, which is black above, except about 
the base of the elytra, and griseous below; rather deeply but not very closely punctate. 
Thorax transverse, with the sides rounded, the disk flat, emarginate in front, the anterior 
angles obtuse and slightly rounded; base a little wider than the base of the elytra, 
bisinuate, with a depression on each side of the disk; posterior angles scarcely pointed 
backwards, obtuse and rounded. Scutellum punctate at the base, smooth at the apex. 
Elytra narrower than the thorax at the base, obliquely truncate, and rounded at the 
apex; coarsely and thickly punctate in somewhat irregular rows; the punctures roundish, 
not oblong. Abdomen finely and rather closely punctate, except towards the apex of the 
pygidium, which is raised, narrow, and impunctate. Mouth, base of antennee, and tarsi 
black, with a tendency to piceous or ferrugineo-piceous. 
From Venezuela. 
30. COLASTUS FULVIPES. 
Oblongus, parallelus, valde depressus, fortiter et creberrime punctatus, fulvo Fig. 41. 
pilosus, niger vel nigro-piceus; thorace brevi, emarginato, basi truncato, E 
angulis posticis fere rectis, haud elytris latiore; elytris creberrime seri- 
atim punctatis et fere punctato-striatis; antennis nigris, basi picea; 
pedibus fulvis. Long. 14 lin., lat. ğ lin. 
Var. Totus piceus. 
Habitat in Brasilia. 
Oblong, parallel, very much depressed, the thorax hollowed out in the middle; very 
closely and strongly punctate, black or nigro-piceous, clothed with stiff fulvous hairs. 
Head thickly punctate; mouth piceous. Thorax deeply emarginate in front, anterior 
angles declinate, projecting and obtusely rounded, subquadrate, base truncate, posterior 
angles nearly right-angled, most coarsely punctate in the middle, the punctures becoming 
finer, closer, and less marked towards the sides and angles; sides rounded in front, 
very slightly behind, so that the profile of the thorax and elytra is nearly continuous. 
Seutellum coarsely punctate, except at the apical margin. Elytra very closely punctate 
in rows, the rows (nearly twenty in number) very close to each other, and the punc- 
tures in the rows sometimes becoming confluent so as to make them punctate-striate, 
depressed towards the suture; the apex of each elytron truncated obliquely from the 
suture, and the external apical angles broadly rounded. Abdominal segments finely 
punctate, nigro-piceous. Legs fulvous. 
From Brazil (Rio Janeiro, &c.). Not rare.
