THREE NEW NEOTROPICAL COPROPHAGOUS 
COLEOPTERA 
By Renaud Paulian 
Laboratoire d’Entomologie du Museum, Paris 
The three new species described herein were sent me for 
study, together with a long series of unnamed coprophagous 
Coleoptera, mostly from the Neotropical region, by the Mu- 
seum of Comparative Zoology of Harvard University. I am 
glad of this opportunity to thank Dr. P. J. Darlington, Jr., 
for the most interesting material he sent me and for his 
generosity in allowing me to keep paratypes of the new 
species. 
Besides the new species, the material sent to me con- 
tained a long series of species of Canthidium. For the most 
part they were probably new, at least the species were 
neither in the Paris Museum, the British Museum, nor in 
my own collection. But it should be necessary, before de- 
scribing new species of this genus, and of the closely allied 
Choeridium, to make a general revision of the species, as 
Harold's monographs are old and rather inadequate. 
I take this opportunity to indicate that TJroxys productus 
Arrow, described from an old specimen without locality 
label, has been collected by Dufau (in coll. Fleutiaux) under 
stones at Trois Rivieres, Guadeloupe Is., West Indies. It 
appears to be rare and found only in unique specimens.
