I have seen only one specimen from Mexico which I should refer to this species. 
C. quadrimaculatus may be known by its very small size, and by its having the head 
blue or greenish, excepting only the margin of the labrum. The legs are nearly black, 
but with reddish-brown tibie in some specimens; the abdomen mottled. In the 
examples I possess of the male the swollen third joint of the antenne is wholly 
yellow. 
Collops histrio (p. 114). 
To the localities given, add :—Mzexico, Northern Sonora (Morrison), Ventanas, Ciudad 
in Durango (Forrer), Pinos Altos in Chihuahua (Buchan-Hepburn); Panama, Bugaba, 
Volcan de Chiriqui 3000 to 4000 feet, Pela Blanca (Champion). 
Rather larger than C. guadrimaculatus, with more of the front margin of the head 
yellow, viz. as far as the insertion of the antenne; and the large joint of the antenne 
in the male always infuscate externally. C. histrio is duller than the following 
species. 
The Mexican specimens are generally of a bright orange hue, and the size and shape 
of the blue spots vary. At San Gerdénimo, where this species was locally very abundant, 
Mr. Champion found it on flowers in the sugar-cane fields. 
6 (a). Collops intermedius. 
Niger; capite antice antennarumque basi testaceis, articulis basalibus nigro notatis; elytris fulvis nitidioribus, 
basi maculisque duabus magnis subrotundatis subapicalibus ceruleis ; pedibus nigris; abdomine ferrugineo, 
apice nigro. Long. 4-5 millim. ¢ Q. 
Hab. Panama, Volcan de Chiriqui (Champion). |
