CAPANEUS.—ARCHIMERUS. 113 
described by Walker as Archimerus muticus, var.?, and represents the typical specimen 
contained in the British Museum, which is a somewhat pale variety, in which the 
yellow spot on the scutellum is larger than in ordinary forms of the species, of which 
Dr. Signoret has afforded me an opportunity of examining a type. 
7. Capaneus odiosus. (Tab. XI. figg. 113,129.) 
Capaneus odiosus, Stal, Stett. ent. Zeit. xxiii. p. 291. 188°; En. Hem. ii. p. 137.77.

This species not only varies in the colour of the abdomen above, as pointed out by 
Stal, and as also occurs in the previous species here enumerated, but also in size, some 
specimens from Guatemala being 24 millims. in length. | 
The specimens figured are a male from Honduras and a female from Guatemala.

(1862). 
Archimerus is at once distinguished from Capaneus by the basal truncated portion of 
the pronotum being wider than the base of the scutellum; and the posterior angles of 
the pronotum are distinct. | 
Six species of this genus are at present known: four are here enumerated from 
Central America; one is a Nearctic form; and the other was described from Venezuela.
