MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 273 
25. COLASTUS TONSUS. 
Valde affinis C. dato; differt pubescentia breviore et magis rufa atque punctis minoribus 
impressus. Long. 2} lin., lat. 14 lin. 
Habitat in Brasilia. 
This species is very similar to C. latus. The chief points of difference are, that it has 
only a short stiff rufous pubescence instead of the longer, flaecid griseous hairs of that 
species, and that the punctuation is smaller and rather more frequent. 
From Rio Janeiro, where it was collected by Mr. Fry, who has presented his specimen 
to the British Museum. 
26. CornaAsTUS THALESTRIS. 
Valde affinis C. Jato; minor, minus nitidus, elytris fere striato-punctatis, Fig. 38. 
abdomine supra subrugose punctato, subtus rufo. Long. 2 lin., lat. قسم‎ 
1+ lin. 
Habitat apud flumina Amazonum. 
Very nearly allied to C. latus, but smaller, of the size and appearance of C. macro- 
pterus (but with only two segments of the abdomen fully exposed above), less shining, 
the punctuation a little closer, and the rows of punctures on the elytra almost united 
into stri ; the underside is rufous or piceo-rufous. In other respects it is very much 
the same as C. latus. 
Collected by Mr. Bates at St. Paul's and Ega, on the River Amazons. 
Section II. Moderately broad and convex. Texture soft. 
Colour of body and thorax rufo-piceous or piceous. Elytra wholly black. 
97. COLASTUS PUBESCENS*. 
Statura C. vulnerati; valde pubescens, levissime subrugulose punctatus, rufus, textura 
molli; elytris nigris, substriatis; pedibus rufis. Long. 14 lin., lat. 1 lin. 
Habitat in Brasilia. 
Oblong-ovate, somewhat convex, opaque, of a soft texture, very faintly subrugosely 
punctate, very thickly clothed with a griseous pubescence; rufous, with the disk of the 
thorax darker (almost piceous) and the elytra black. Thorax broad, short, transverse, 
narrowed and emarginate in front, with the base truncate, the posterior angles almost 
right-angled ; the sides rounded. Scutellum rather large. Elytra short, very faintly 
substriate; apex of each elytron very obliquely truncate and rounded. Legs rufous. 
The soft and dull texture of this species is like that of Colastus infimus or Carpophilus 
melanopterus, the latter of which it also resembles in colour. 
From Brazil. In the collection of M. Deyrolle. 
* 1 think it right to mention that the notes from which this description is made were taken at an early period in 
my study of this family, and before I was so familiar with its characters as I have since become. I therefore have not 
the same confidence in its completeness as in that of most of the other species.
