. SCHGENICUS. 21 
in S. chalybeus, very closely, evenly, and rather coarsely punctured; elytra wider than the thorax, con- 
fusedly, rather finely, and not very closely punctured, without any rows of coarse punctures. 
Length 9-10 millim. 
Hab. Mexico (coll. &. Bates), El Camaron (Saldé). 
Four examples, apparently all females. Very close to S. chalybeus and sent from 
the same locality. The elytra, however, are so differently punctured that it seems 
scarcely possible to unite them; the thorax is also more closely and finely punctured. 
Labelled £. punctatissimus, Chev., in the Sallé collection. 
9. Schenicus basalis. 
Oblong oval, rather broad, convex, dark greenish bronze, dull. Head coarsely and closely punctured; pro- 
thorax scarcely broader than long, convex, widest at the base, the sides nearly straight towards the base, 
rounded and narrowed in front, the anterior angles not prominent, the hind angles rectangular, the base 
strongly bisinuate, very closely and coarsely punctured, the punctures a little confluent, rounded and 
shallow; elytra comparatively broad, rounded at the sides, wider than the thorax, closely finely and 
shallowly punctured, the punctures indistinctly arranged in rows, finely and shallowly wrinkled trans- 
versely towards the sides, the base more closely and confusedly punctured. Beneath dull, very closely 
and shallowly punctured. 
Length 9-94 millim. 
fab. Mexico, Almolonga (Hége). 
Two examples. Duller and broader than its allies, the elytra with rounded, very 
shallow punctures; the thorax very closely almost confluently punctured. 
10. Schenicus niger. 
Oblong ovate, convex, dull bronze-black. Head closely and finely punctured; prothorax a little broader than 
long, convex, widest behind, the sides rounded and narrowed in front, feebly rounded and almost straight 
behind, the lateral margins a little thickened, the anterior angles obtuse, the hind angles scarcely promi- 
nent, subrectangular, the base strongly bisinuate, closely evenly and coarsely punctured, with an indistinct 
or obsolete smooth central line; elytra rather long, convex, somewhat pointed behind, wider than the 
thorax, with irregular rows of coarsish punctures, the interstices confusedly and sparingly punctured, the 
punctures scarcely finer than those of the strie, indistinctly wrinkled transversely at the sides. 
Length 9-93 millim. 
Hab. Guatemata (Sallé), San Joaquin (Champion). 
Two examples. Labelled Hpitragus niger, Haag, in the Sallé collection. Narrower, 
smaller, and more convex than S. viridis; the elytra somewhat pointed behind, almost 
black in colour, and more sparingly punctured. 
Sect. 2. Prosternum a little produced behind, horizontal. 
11. Schenicus pectoralis. (Tab. I. fig. 17.) 
Oblong ovate, convex, bright cupreous or greenish bronze. Head closely and coarsely punctured, the eyes 
carinated within ; prothorax scarcely broader than long, widest at the base, the sides rounded and nar- 
rowing to the front, feebly sinuate before the rather prominent outwardly directed hind angles, the 
anterior angles a little produced, obtuse, the base bisinuate, closely and rather coarsely punctured, a little 
more finely and closely at the sides; elytra wider than the thorax, sides rounded, widest about the
