A very variable insect. The var. magnificus, the predominant Central-American 
form, does not extend south of Nicaragua, and the var. sutwralis is confined to Central 
and Northern Mexico; but amongst the Costa Rican series, which are mostly wholly 
green, like the typical S.-American £. festivus, there are several specimens showing 
traces of the cupreous spots on the elytra, so that no value can be placed on this 
character. A few small examples from Teapa, British Honduras, and the Polochic 
valley (both with and without the cupreous spots) have the side-pieces of the meso- 
and metasternum rather coarsely punctate, and the elytral interstices more distinctly 
punctured than usual towards the apex. The elytra are deeply excavate and foveate 
at the base, and the humeri are more or less angularly dilated. The males have the 
outer joints of the funiculus strongly transverse, and 2~7 sulcate beneath, the anterior 
tibiee slightly elongated, the first ventral segment depressed in the middle and the 
fifth furnished with a deep, transverse, piligerous fovea near the apex. The females 
have a smoother rostrum, a more slender funiculus, and the anterior tibie shorter and 
more distinctly crenulate within ; the fifth ventral segment is sometimes obsoletely 
foveate in this sex. The form of the var. suturalis with a bluish suffusion on the 
cupreous portions of the upper surface, from Tonila and V 
entanas, is perhaps the most 
brilliantly-coloured Barid yet discovered.
