pubescens, opacus, picescens, antennis pedibusque ob- 
scurioribus. Long. 24 mm. 
Antenne red, with the small intermediate joints yellow, 
the club of moderate length, its first joint dilated in- 
ternally, triangular, the following joint rather narrower, 
the terminal joint still more slender, and of an elongate, 
narrow, oval form. Head finely punctate. Thorax 
closely and finely punctate, as are also the elytra.

‘his is similar in puncturation to C. punctatus, but 
is paler in colour, and has the antenne very much 
smaller. 
The habitat is the same as that of C. punctatus.

Mirosternus muticus, n. s. 
Nigricans, capite antennis pedibusque piceo-rufis, 
tenuiter pubescens, subnitidus, elytris ad apicem dense 
punctatis. Long. 23 mm. 
Antenne reddish, with the club darker, the joints of 
the latter similar in form to those of C. punctatus, but 
rather broader and shorter, and the terminal joint more 
obliquely truncate at the extremity. Head impunctate, 
except at the margins; thorax almost impunctate, but 
very distinctly pubescent. Hlytra densely punctate at 
the extremity, but the puncturation in front becomes 
obsolete, and there is thus left at the shoulder a large 
clabrous shining space. Legs reddish.
