858 SUPPLEMENT. 
A small species without at first sight any special character to distinguish it, and of 
which at present among the few examples we possess I have not been able to 
distinguish sexes. 
It may be compared to the European C. vestitus and C. oblongus, with which, as to 
size and vestiture, it agrees fairly well, but the thorax is broader and does not narrow 
in front ; the punctuation is more confused ; the club of the antenne is laxer, and hairy, 
its two first joints are not transverse, and its apical joint is acuminate. The pubes- 
cence is serial. In the less mature examples the elytra have a slight olivaceous tinge. 
12. Cis cylindrus. | 
Elongatus, cylindricus, nigro-piceus; elytris piceis, dense subtiliter, prothorace minus crebre, punctatis ; 
pedibus rufis ; antennis testaceis, clava fusca. Long. 27 millim. 
Hab. Panama, Caldera in Chiriqui (Champion). 
A species of Cis resembling the European C. alni in size. Its head is as wide as the 
thorax in front, densely and finely punctate. The thorax is longer than wide, thickly but 
distinctly, and rather sparsely, punctured near the base; the disc has a constricted 
transverse impression ; the sides are much deflexed, and with the base are margined by 
a fine line. The elytra are densely punctulate, not deeply nor at all in series; the 
suture is even, without any distinct stria, and no pubescence or sete are visible. There 
is but one specimen which I can assign to this species, and the description is therefore 
provisional and defective. A single specimen of a Cis from Tolé, and one from Mexico, 
come very near to it, but it would be rash to assume they were conspecific. 
13. Cis ——? 
Hab. Mexico, Oaxaca (Sallé). 
Several specimens of a minute species, about one millimetre in length and with 
pruinose pubescence; apparently all are females, and I do not consider there is sufficient 
material for its description. 
14. Cis ——? 
Hab. GuatEMALA, Zapote (Champion). 
Another minute species. Two specimens. 
15. Cis ——? 
Hab. Guatrmaa, Zapote (Champion). 
The antenne in this minute species appear to be nine-jointed, but there being 
only two specimens, the material is not sufficient to yield the necessary examination 
by dissection.
