This species, although closely related to C. hollisi, Wat., 
has a peculiar aspect, due to the transparent hyaline elytra 
producing a mimetic resemblance to the wings of a small 
bee. The black margins and lines of black dots, upon which 
fine setze are placed, simulate the venation, and, in conjunc- 
tion with the white spots and bars upon the pronotum and 
abdomen, seemed designed to imitate the bees of the genus 
Melecta or some allied genus. Various species of these bees 
inhabit the same region and probably frequent the same 
flowers. 
The head is like that of C. nyasse and hollisi, deeply 
bilobed and clothed with rather scattered sete. The pro- 
thorax is scarcely wider than the head across the eyes and a 
little shorter than it is long, with the front angles obsolete 
and the hind angles very obtuse, and the sides bluntly 
angulated before the middle. The upper surface bears 
irregularly scattered sete, which broaden into scales arranged 
in five clusters on each side, one placed at each angle and 
the other three forming a triangle upon the disc. The 
scutellum is long and clothed with similar sete. The trans- 
parent elytra have a yellow tinge, but the inner and outer 
margins, as well as the lateral costa and longitudinal lines 
of irregular dots, are black. The hyaline effect is due to the 
wings beneath being visible through the elytra, and the 
appearance of a bright yellow spot is produced on each side 
of the apex of the scutellum by a brush of long white hairs 
upon the metanotum showing through at that point. The 
pygidium is rugulose and bears two longitudinal bands of 
white scales narrowly separated. 
The sexual differences of the genus Calometopus have 
never been described, most of the species having been 
hitherto represented by female specimeus only, although the 
type of C. hollisi, Wat. (which I have not seen), is evidently 
a male. The remarkable trilobed hind tibia, regarded as a 
generic character by Blanchard in the original description, 
and since by Péringuey and Bourgoin, is a feature peculiar 
to the females.
