a Family of Coleopterous Insects. 673 
abdomine pauld breviora. Pedes longiores, femoribus tibiis- 
que simplicibus. 
This species was received by the late Mr. Francillon from 
New Holland, and was figured by Donovan in his work upon 
the insects of that country. 
I am not aware in whose possession the original specimen is 
at present. It differs materially from the C. latipes not only in 
its uniform brunneous colour, but also in its narrow form and 
more slender legs. The preceding specific characters are chiefly 
derived from Donovan’s figure of the species, his description 
being very short. 
Mr. Donovan also speaks of another species of this genus 
brought from Bengal by M. Fichtel, who consigned it to the 
Imperial Cabinet at Vienna, of which, however, he has unfortu- 
nately omitted to give the characters, and, as far as I have been 
enabled to ascertain, the entomologists of that city have not yet 
supplied the deficiency.
