ANTHOCOMUS. 115 
1. Anthocomus plagiatus. 
Niger, nitidus; prothorace rufo, plaga lata discoidali nigra; elytris griseis, cinereo-pubescentibus, nigro-pilo- 
sellis. Long. 4 millim. 9. 
Hab. GuatEMALA, Calderas (Champion). 
Head nearly as wide as the thorax, broadly impressed in front, black, the front and 
sides as far as the insertion of the antenne testaceous; the antenne are faintly serrate 
from the fifth joint; the two basal joints are yellow beneath. The thorax is orbiculate, 
rather broader than long, red, with a broad black central vitta, which does not touch 
the front margin. The elytra are ashy grey, opaque. Body beneath and legs black. 
Var.? Thoracis disco nigro limbo posteriore et angulo antico tenuissime testaceis. 
Hab. GuateMata, Calderas (Champion). 
Three specimens from Calderas differ in having the thorax nearly totally black; but 
as two of these have the narrow testaceous edge wider at the front and hinder angles, 
they will probably be only regarded as varieties of A. plagiatus. 
2. Anthocomus byssinus. 
Anthocomus byssinus, Erichs. Ent. p. 109°. 
Hab. Mexico}. 
I have not been able to identify this species. It is apparently near to the variety 
described above, but with a lateral vitta on the margin of the elytra. 
3. Anthocomus maculosus. (Tab. VII. fig. 1.) 
Rufus, nitidus; prothoracis maculis duabus, elytrorum basi maculisque duabus magnis subrotundatis prope 
apicem, mesosterno, femoribus (anticis et intermediis intus rufis, posticis basi rufis), antennis, tibiis et 
tarsis nigris. Long. 34 millim. 4. 
Mas. Tarsi antici articulis duobus primis rufis, art. 2° supra lobato. 
Hab. Guatemata, San Gerdnimo (Champion). 
Var. Capite prothoraceque nigris, ore testaceo. @. 
Hab. GUATEMALA, Chiacam (Champion). 
Shining, very obsoletely pubescent, and with a few black erect hairs here and there. 
Head and thorax red, the former faintly clouded on the crown, the latter with two 
conspicuous round spots, one on each side. The elytra have a band at the base scarcely 
so wide as the length of the thorax, and a large, round, but somewhat irregular spot 
near the apex black; they are convex, and evenly widened a little behind. Under- 
neath the only black part is the metasternum. The variety only differs in having the 
head and thorax black above, the mouth being yellow: there are two specimens from 
Chiacam which agree in this respect, and which are females; it is therefore possibly a 
sexual distinction. The antenne are black, with two or three joints at the base testa- 
ceous, in the female variety spotted with black above.
