COLEOCERUS. 307 
2. Coleocerus virescens, sp. n. (Tab. XIV. figg. 12, 12a.) 
Oblong-ovate, piceous, densely clothed with intermixed pale green and cinereous scales, those on the under 
surface metallic, the elytra mottled with fuscous. Rostrum sulcate and deeply excavate. Antenne 
rather slender, the joints of the funiculus becoming shorter and stouter outwards, 2 shorter than 1. 
Prothorax strongly transverse, explanate and sharply margined at the sides posteriorly, obliquely 
narrowed thence to the apex, and distinctly narrowed at the base, the base itself deeply bisinuate, the 
hind angles acute; densely finely punctate. Scutellum broad, strongly transverse. LElytra oblong, 
scarcely wider than the prothorax, punctate-striate, the interstices feebly convex. Mesosternal 
protuberance long, compressed. Legs stout. 
Length 43, breadth 23 millim. (9?) 
Hab. Mexico (Sallé). 
One specimen, without definite locality. This is the only species of the genus 
known to me with a large admixture of green scales and the prothorax sharply 
margined at the sides behind. The last-menticned character brings C. virescens near 
the Texan C. dispar (Lec.), which has the prothorax more feebly sinuate at the 
base, &c. 
3. Coleocerus denticollis, sp.n. (Tab. XIV. figg. 13, 13 a.) 
Oblong-ovate, piceous; the prothorax and elytra densely clothed with brownish-cinereous, and the rest of 
the surface with whitish or cinereous, scales. Rostrum sulcate and deeply excavate. Prothorax 
strongly transverse, angularly dilated at the sides before the base and obliquely narrowing thence to the 
apex, the sides margined posteriorly and emarginate between the angular dilatation and the sharp hind 
angles, the base bisinuate ; densely, finely punctate. Scutellum transverse. Elytra not wider than the 
prothorax, narrowing from the base, closely punctate-striate, the interstices feebly convex. Mesosternal 
protuberance long, slightly curved upwards, blunt at the tip. Legs very stout. 
Length 43, breadth 2,4, millim. (2 ?) 
Hab. Mexico, Acapulco (£f6ge). 
One specimen. Distinguishable by the angularly dilated, posteriorly margined sides 
of the protborax and the uniform vestiture—brownish-cinereous above and whitish 
beneath. 
4. Coleocerus variegatus, (Tab. XIV. figg. 14, 14a, ¢; 15, ¢, var.) 
Colecerus variegatus, Boh. in Schénoh. Gen. Cure. viii. 2, p. 405°. 
Length 34-8, breadth 13-33 millim. 
Hab. Mexico, Jalapa, Cerro de Palmas (Z/ége), San Andres Tuxtla, Juquila, 
Tepanistlahuaca (Sal/é), Salina Cruz (Anaéd, in U.S. Nat. Mus.), Oaxaca!; Guaremara, 
Volcan de Atitlan, Tocoy (Champion). 
The numerous specimens referred to this species (the only one from Oaxaca to 
which Boheman’s description is applicable) differ from C. setosws in having the 
prothorax distinctly narrower than the elytra at the base, and the sides not or feebly 
margined posteriorly ; the vestiture coppery-brown or brown variegated with cinereous 
or whitish, the light scales on the prothorax condensed into a narrow median line and
