CHLAMYS. 171 
The single male specimen obtained by Mr. Champion is well distinguished from 
similarly-coloured species by the sculpturing of the thorax. 
47, Chlamys angulicollis. (Tab. XL. fig. 11.) 
Obscure dark fulvous, opaque ; thorax finely granulate-punctate, with two lateral black bands, the posterior 
angles tuberculiform ; elytra with two longitudinal coste (the first short and S-shaped) connected by 
transverse short ridges, the apex with two tubercles. 
Length 2 lines. 
Head finely rugose, fulvous; antennz obscure fulvous, the last four joints black, the fourth and following 
joints strongly transversely serrate; thorax with its middle portion gradually raised, the elevation 
bounded at the base by a deep transverse groove, and with a rather acute edge behind, the posterior 
angles produced into a blunt tubercle, the surface extremely closely and finely punctured and granulate, 
reddish-fulvous, entirely opaque, with a black, anteriorly widened, dentate band on each side, extending 
from the top of the elevation nearly to the anterior margin, and a small very obscure black spot near the 
lateral margin ; elytra of a paler colour than the thorax, rather closely impressed with black punctures, 
and with two distinctly raised costee—the first S-shaped, near the suture (its commencement marked by a 
tubercle), and joined at the middle by a short transverse ridge to the second costa, the latter commencing 
at the middle of the base and extending nearly to the apex where it ends in a tubercle,—the shoulders 
also costiform and with a short black stripe (if looked at sideways, the elytra also appear to have a 
transverse ridge before the middle, this ridge connecting the second costa with the more indistinct 
lateral ones, and a ridge at the sides below the transverse one); pygidium rather remotely punctured ; 
underside and legs dark brown, with black markings in the coxal cavities. 
Hab. Guatemata, San Gerénimo (Champion). 
A single specimen. 
The black bands and shape of the thorax, in connection with the two plainly marked 
elytral costa, separate C. angulicollis from any of its congeners. 
48. Chlamys gaumeri. 
Cylindrical, obscure fuscous; thorax transversely convex, the elevation reticulate-punctate and scarcely 
perceptible ; elytra closely punctate and reticulate, without tubercles and with very indistinct ridges, a 
black spot on either side of the suture near the base. 
Length 17 line. 
Head finely rugose, obscure fulvous, with a small indistinct fuscous spot on the vertex ; anterior margin of the 
epistome black ; labrum testaceous ; antenne fulvous, the terminal joints darker ; thorax subcylindrical, 
regularly convex, the middle portion scarcely perceptibly raised, the surface of a dull brownish-fuscous 
colour, closely reticulate on the disc, finely punctured at the sides; elytra of the same colour as the 
thorax, with some slightly raised ridges, of which two extending from the middle of the base to near the 
apex are more plainly marked than the rest, the former limiting externally a black smoother space placed 
below the scutellum, the rest of the surface closely and deeply punctured and reticulate, the suture 
dentate throughout ; pygidium closely punctured, and with two very short coste at the base; underside 
and legs coloured as above, the former closely reticulate. 
Hab. Mexico, Temax in North Yucatan (Gawmer). 
The feebly raised thoracic elevation and indistinct elytral ridges, the subcylindrical 
shape, and the very dull fuscous colour distinguish C. gawmeri from any of its congeners. 
One example only, a female, has been received.
