larger; the elytra are pale yellow, with a more or less obsolete basal fascia, and the 
tips black ; the legs yellowish, with infuscate knees, tibie, and tarsi; the body yellow. 
It is very doubtful to me whether this, and some allied species, can be maintained as 
distinct.

Hab, Mexico, Juquila (Boucard, coll. Sallé). 
Allied to C. triste, but duller, entirely black, and with the intervals of the cost 
(which are much less raised) with very close irregular transverse lines, scarcely ever 
forming cells. 
Two specimens in Sallé’s collection are all I have yet seen. 
Calopteron rufulum (p. 13). 
To the localities given, add :—Panama, Bugaba, Volcan de Chiriqui (Champion). 
Taken commonly. Some examples are very small, and have the centre of the thorax 
and scutellum infuscate. 
16 (a). Calopteron sinuatocolle. 
Elongatum, nigro-piceum ; prothorace elytrisque sordide flavis, illo disco carinato, medio infuscato, his tricostatis 
triente apicali nigro-fusco ; ore, pectore et trochanteribus flavo-testaceis. Long. 9-10 millim. Q. 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
This is at first sight rather puzzling from its resemblance to species of the 
C. matutinum group. It has, however, an entire carina to the thorax, the sides of 
which are bisinuate, much as in C. rufulum, to which it appears related. The base of 
the thorax is bisinuate, the middle being angularly produced to meet the carina, and 
not notched. The elytra are very slightly infuscate on the suture at the base, and the 
apical patch leaves the margin pale for some distance towards the apex. 
The antenne of the female are acutely serrate.
