Central-American specimens of this variable species belong to the var. 6 of La Ferté. 
I have examined his types of A. vicinus and A. letus, and fail to find any difference of 
importance between them ; the latter chiefly differing from the light-coloured form of 
A. vicinus in having the elytra black at the base. Texan examples of the typical form 
and of the var. 6 of A. vicinus have been communicated by M. Sallé and Dr. Horn for 
comparison. ‘The species is common in Mexico and Guatemala. A. vicinus is allied 
to A. floralis, but is very much narrower and smaller than that insect, and the head is 
without occipital impression. Central-American specimens are of a bright reddish- 
testaceous colour, the elytra each with a large spot on the disc about the middle 
(sometimes in the form of a broad transverse fascia almost united to the opposite one 
at the suture) and the apex black; sometimes the elytra have a triangular scutellar 
patch, or the base narrowly, infuscate. In the United States entirely dark forms occur. 
The upper surface is very shining and almost glabrous; the head and thorax bear fine 
widely scattered punctures ; the elytra are long, rather depressed, coarsely and some- 
what thickly punctured ; the legs and antenne are testaceous.

Hab. Mexico! (coll. Oberthiir), Mexico city (Hage), Guanajuato (Sallé, ex Dugés). 
Our specimens from Guanajuato and Mexico city agree perfectly with La Ferté’s 
type. They are black and very shining ; the head is comparatively long, and subangu- 
larly dilated at the sides behind; the eyes are very small; the thorax is obliquely 
narrowed from a little before the middle, margined at the base; the elytra are long, 
parallel, and depressed, coarsely punctured, with prominent humeri and the suture a 
little raised ; the upper surface is almost bare.

Hab. Norra America, San Diego in California !, Arizona.—Mexico, Northern Sonora 
(Morrison), San Pedro in Coahuila (Dr. Palmer), Villa Lerdo in Durango (Hége). 
We have received numerous examples of this species from the late Mr. Morrison 
under the name of A. nigritulus, Lec.; they agree, however, much better with the 
description of A. confinis, a specimen of which, from Arizona, has been communicated 
by Dr. Horn. Less parallel than A. infernus; the eyes larger, the elytral punctuation
