CHLAMYS. 163 
14 (p). Chlamys punctipennis. (Tab. XX XIX. fig. 22.) 
Subquadrate, narrowed posteriorly, obscure zneous, the labrum, antennx, and tarsi fulvous; thorax minutely 
granulate, the elevation channelled and with a tubercle on each side; elytra with a strong oblique ridge 
before the middle, the space between this and the base closely punctured, the posterior portion with four 
or five tubercles. 
Length 14 line. 
Hab. Mexico, Jalapa (Hoge), Cordova (Sallé); Guatemata, Zapote (Champion) ; 
PanaMA, near the city (Champion). 
In colour and in sculpture this species resembles Diaspis mestifica, from which the 
single scutellum and the red tarsi at once distinguish it; the last-mentioned character 
and the different sculpture of the elytra will separate it from C. assimilis and C. plicata, 
Lac. The thorax has the surface minutely granulate throughout and remotely punc- 
tured, and has a rounded tubercle on each side; the elevation is, as usual, divided at 
the top, each part having a rather obsolete ridge running down sideways, and another 
_ obsolete and shorter ridge may be seen near the anterior portion. The elytra have the 
space between the oblique ridge and the base closely punctured and semireticulate, and 
of a darker appearance in certain lights than the rest of the surface; the oblique ridge 
is strongly raised (as in some of the allied species) and near the suture forms an arcuate 
transverse tubercle ; immediately behind this another transverse, less acutely raised ridge 
is placed, and an elongate elevated tubercle is situated close to the suture near the apex. 
C. punctipennis may be known by the posteriorly narrowed shape, the closely punctured 
anterior portion of the elytra, and the red tarsi; C. tragulus, Lac., differs in the colour 
of the underside and in other particulars. 
Our figure is taken from a specimen from Cordova. 
Chlamys decipiens (p. 80). 
To the locality Mexico, add:—Chilpancingo in Guerrero (H. H. Smith), Cordova 
(Hoge). 
Two specimens from the above localities agree very well with Lacordaire’s description. 
C. decipiens is of a very obscure eneous colour, and may be known from other similarly- 
coloured species by the sides of the pygidium and of the abdomen being fulvous; the 
thoracic elevation is divided at the top into two parts, each of which has a distinct 
ridge running to the base. 
Chlamys pilatei (p. 81). 
To the locality Mexico, add :—(coll. Jacoby). 
17 (a). Chlamys polycocca. 
Chlamys polycocca, Lacord. Monogr. p. 704’. 
Hab. Norra America 1.—Mextco, Cordova (Hoge).
