114 MALACODERMATA. 
6. Collops histrio. 
Collops histrio, Erichs. Ent. p. 59°. 
Hab. Unitep Statzs, California 1.—Mextico, Etla, Oaxaca (Boucard, coll. Sallé, Hoge), 
Misantla, Cerro de Plumas (H6ége); GuaTEMALA, San Gerdnimo, Guatemala city 
(Champion). 
Although the specimens in Sallé’s collection stand under the name “ guadrimacu- 
latus, Say,” they agree more closely with the species to which I refer all the specimens 
collected by Hoge and Champion. C. histrio differs, according to Erichson, from 
C. 4-maculatus in the basal cyaneous spots touching the suture and external margins, 
and is a little larger on the average. They are evidently very nearly allied to each 
other. 
7. Collops decorus. 
Collops decorus, Erichs. Ent. p. 59°. 
fab. Mexico! (Sturm, coll. Sallé). 
Differs from C. geminus by the unspot ed thorax and red abdomen. I observe, 
however, that in specimens of C. geminus from Guatemala the segments of the abdomen 
are red with a pitchy centre, or a wide spot on each side, while in one at least of the 
two specimens named C. decorus in Sturm’s writing, the femora are red, and in the 
other are, with the abdomen, obscure, the specimens being old. The identification of 
these specimens must therefore be considered a little doubtful. 
8. Collops vittatus. (Tab. VI. fig. 23.) 
Malachius vittatus, Say, Journ. Ac. Phil. ii. p. 184°; Amer. Ent. in. t. 48, 
Megadeuterus haworthi, Westwood, Trans. Ent. Soc. i. p. 98, t. 10. fig. 9 *. 
Collops vittatus, Erichs. Ent. p. 617. 
Hab. Unitep States, Mississippi!.—Mexico?, Puebla, Orizaba (Sal/é), Misantla 
(Hoge). 
The specimen figured is a variety which wants the thoracic spots, from Puebla. 
The two spots are present in a single specimen from Misantla, and in one from 
Orizaba. 
ANTHOCOMUS. 
Anthocomus, Erichson, Entomographien, p. 97. 
The European Anthocomi are well known as gay little insects delighting in flowering 
herbage in summer. The species which have the second joint of the tarsi of the male 
produced so as to cover the two following are now generally placed in Attalus. The 
males of some species have the apex of the elytra indented and with appendages ; but 
I have not yet seen a Central-American species of this form.
