166 PHYTOPHAGA.—SUPPLEMENT. 
six strongly raised and some smaller black or metallic purplish isolated tubercles; breast and legs spotted 
with black. 
Length 2 lines. 
Head flavous, with a few dark punctures and a black spot on the vertex, and a smaller spot above each eye; 
antenne fulvous; thorax with two acutely-raised crests or ridges which are separated by a deep channel, 
each crest being divided at its apex into three prominences or tubercles, the disc flavous, the sides, the base, 
and the space between the two principal ridges spotted with black; scutellum flavous, its base black ; 
elytra with deep punctures, strongly raised isolated tubercles (one at the middle of the basal margin, two 
smaller ones placed obliquely between the shoulder and the suture, three in the same direction below the 
middle, and two large ones of trigonate shape near the apex), and a short transverse prominent ridge near 
the suture at the middle, the tubercles of a shining black colour, the two apical ones purplish-blue ; 
pygidium flavous, with a large black spot near the apex; the underside flavous, spotted with black ; 
abdomen with a small tubercle on either side, the tubercle marked with black; legs flavous, the femora 
with a large central black patch. 
Hab. Guatemata (coll. Jacoby). 
Allied to the Brazilian C. schotti, Koll., but differing in the sculpture of the thorax 
and of the elytra, and in: the tubercles of the latter being partly metallic in colour. 
We have received a single specimen of this interesting new species from the Stuttgart 
Museum. 
20 (p). Chlamys nitidiceps. (Tab. XI. fig. 6.) 
Narrowly elongate, obscure reddish-cupreous, the base of the antenne, the labrum, and the tarsi flavous; thorax 
irregularly tubervulate, its elevation channelled; elytra deeply punctured, the apex with some blunt 
tubercles, the disc with obscure longitudinal ridges. 
Length 1 line. 
Head flattened, finely reticulate-rugose ; labrum fulvous; antenng with the basal joint flavous, the other joints 
obscure fuscous ; thorax with the middle portion moderately raised, the elevation bounded posteriorly and ~ 
at the sides by a deep sulcation and divided in the middle by a shallow channel—each division forming a 
blunt longitudinal ridge at the apex and indistinctly divided into two blunt tubercles, the anterior portion 
with a short transverse ridge placed in front of the longitudinal one,—the entire surface irregularly reti- 
culate; elytra closely and deeply punctured, with a broad longitudinal ridge down the middle—the surface 
of the ridge impressed with two rows of punctures and the ridge itself ending near the apex in a blunt 
tubercle,—three blunt tubercles near the apex, an indistinct costa running close to the suture from the 
base to the middle, where it joins the broad ridge by a transversely-shaped tubercle, a blunt tubercle at 
the middle of the base, and a short transverse ridge at the sides near the middle, the suture denticulate 
throughout ; pygidium with three distinct longitudinal coste, the spaces between the coste hollowed ; the 
femora dark fuscous, the tibia cupreous in tint. 
Hab. Guatemaua, Cerro Zunil (Champion). A single specimen. 
The uniform obscure reddish-cupreous colour, the elongate shape, and the tricarinate 
pygidium distinguish this small species from its allies, C. schuchtt, Koll., from Brazil, &c. 
It also differs from C. schuchti in the sculpture of the thorax and in the colour of the 
legs. In C. nitidiceps the tibie are distinctly cupreous. 
Chlamys stictica (p. 83). 
To the Mexican locality given, add:—Cuernavaca, Jalapa (Hoge), Atoyac in Vera 
Cruz, Cordova (Sallé), Teapa in Tabasco (H. H. Smith).
