116 RHYNCHOPHORA. 
each of the femora and tibie is strong and sharp, as is also the one at the inner apical 
angle of the latter. 
4. Sternechus foveolatus, sp. n. 
Robust, subelliptic, black, shining, somewhat thickly pubescent. Head and rostrum closely punctate, the 
latter short and very stout, the eyes rather distant. Prothorax transverse, a little rounded at the sides, 
narrowing almost from the base and constricted in front, the lateral margins (as seen from above) crenate ; 
the surface uneven, closely and equally punctate throughout. Elytra subcordate, very convex, conjointly 
rounded at the apex, the humeri rounded and moderately swollen, the infra-humeral prominence conical 
and almost pointed; closely seriato-foveolate, the interstices narrow, transversely wrinkled, and sparsely, 
minutely punctate. Beneath closely punctate. Femora and tibie each armed with a short tooth, the 
inner edge of the tibiee denticulate between this and the apex. 
Length 9, breadth 5 millim. 
Hab. Mexico, Amula in Guerrero ({. H. Smith). 
One specimen. Distinguishable amongst its allies by the seriato-foveolate elytra, 
very stout rostrum, and somewhat close pubescence. 
5. Sternechus brevicollis, sp.n. (Tab. VII. figg. 22, 22a, b.) 
Subelliptic, bronze-black, shining, clothed with very minute, scattered, hair-like scales, the legs sparsely 
pubescent. Head closely, the rostrum sparsely and much more finely, punctate, the latter short and 
stout, shorter than the prothorax, the eyes narrowly separated; antenne short. Prothorax strongly 
transverse, very feebly rounded at the sides, abruptly narrowed and also slightly constricted in front; the 
surface closely punctate, the punctuation becoming coarser towards the sides, with finer punctures inter- 
mixed. Elytra subcordate, convex, conjointly rounded at the apex, the humeri rounded and moderately 
swollen, the infra-humeral prominence triangular; seriate-punctate, the interspaces as wide as the 
punctures, transversely wrinkled, and minutely punctate. Legs short; femora armed with a strong 
tooth ; tibia angularly or subangularly dilated on the inner side about the middle, the anterior pair 
sharply so, and the space between this and the apical tooth very finely serrate. 
Length 6, breadth 34-34 millim. 
Hab. GuatEMALA, Panzos in the Polochic Valley (Champion, Conradt). 
‘Two specimens, probably male and female, one of them immature and showing 
traces of dark fascize on the elytra. Less elongate than S. nitidus, with the rostrum, 
prothorax, and legs shorter; the femora strongly dentate; the submedian tibial tooth 
reduced to an angular dilatation, which is almost obsolete on the hind pair, the space 
between this and the apex very finely serrate; the lateral prominences of the elytra 
less extended. 
6. Sternechus fuscomaculatus, sp. n. (Tab. VII. figg. 23, 23 a, b.) 
Broad-ovate, robust, black, shining ; the head, prothorax, scutellum, humeral callus, and under surface sparsely 
clothed with very minute, hair-like, fuscous or fulvous scales ; the elytra(except at the shoulders) densely 
clothed with rather coarse, narrow, cinereous or flavo-cinereous scales, with a large spot on the disc below 
the base, another on the subapical callus, and a common, sinuous, median fascia, sometimes interrupted 
at the suture, fuscous ; the legs sparsely pubescent. Head closely punctate, foveate between the eyes, 
the latter somewhat narrowly separated; rostrum exceedingly stout, shorter than the prothorax, sparsely 
punctured, Prothorax strongly transverse, much narrowed and constricted in front and slightly narrowed
