It is in error that C. furcifer is given as a synonym of this species. I was in fact 
led into the mistake by specimens of C. furcifer being labelled C. militaris in Sallé’s 
collection ; these are those from Tuxtla. The specimens from San Juan in Vera Paz 
also belong to C. furcifer, one of which is figured on Tab. X. fig. 26. I had not at the 
time the opportunity of verifying these species with M. Mellié’s descriptions and figures, 
which I have now done. The localities given under C. militaris on p. 223 all therefore 
refer to C. furcifer, which should follow the present species. 
There are, however, eight specimens from Vera Cruz in Sallé’s collection which I 
refer to C. militaris, with perhaps a very little uncertainty, the thoracic prominences 
in the male being a little less pronounced, and the whole insect more cylindrical than 
Mellié’s figure would appear to represent. It is also to be regretted that Mellié was 
not informed of, or did not give, the precise locality in Mexico from whence his species 
came. Our species is the smallest I have yet seen of this group; from C. furcifer it 
differs entirely by the two small reflexed projections on the front of the thorax in the 
male, in which sex the clypeus bears a reflexed ridge in front, which appears to be 
bidenticulate. The females are of course very difficult to separate, but it is probable 
that the nearly allied species will not generally occur together ; in this species the very 
small size and cylindrical form will serve for a distinction. 
1 (a). Ceracis furcifer. 
Ceracis militaris, Mellié, Ann. Soc. Ent. Fr. 1848, p. 379; ante, p. 223 (partim). 
To the Guatemala locality given, add :—Yzabal (Sal/é). 
Mellié informs us that he had seen many examples of this species in Melly’s collection, 
from Cayenne and Peru, and in Chevrolat’s and Reiche’s collection, from Surinam. 
It appears to me highly improbable that all these really pertained to C. furcifer. 
Sallé’s specimens from Guatemala, he says, were taken at Yzabal in a species of 
Polyporus. I apprehend there are many closely allied species *.

* T possess two specimens of a Cis from Mexico labelled respectively Ceracis variabilis and Ceracis mutabilis, 
Chevrolat. It is in the highest degree improbable that these specimens are correctly named, as both are 
females; or that a species from Cuba should also occur in the interior of Mexico.
