STERNECHUS. 117 
towards the base, feebly, subangularly dilated at the sides a little behind the middle ; the surface closely, 
very finely punctate, with a narrow smooth space down the centre. Elytra very convex, broad, conjointly 
rounded at the apex, the humeri rounded and much swollen, the infra-humeral prominence large and 
subconical; seriate-punctate, the interstices closely, minutely punctate. Beneath sparsely punctate, the 
punctures on the ventral surface very fine. Anterior and intermediate femora acutely dentate; all the 
tibize setose along their inner edge. 
Length 10-123, breadth 53-7 millim. 
Hab. Nicaragua, Chontales (Belt). 
Four specimens. Very different from all the other Central-American forms. 
7. Sternechus aurocinctus, sp. n. (Tab. VII. figg. 24, 24a, 4.) 
Subelliptic, robust, black, dull; the prothorax above thickly clothed with very minute brownish or fulvous 
scales, its flanks and the entire under surface of the body with a scattered, coarser, pallid squamosity ; 
the elytra thickly clothed with small fuscous or blackish scales, with a common, narrow, straight, 
transverse fascia below the base, and a curved transverse fascia some distance before the apex, densely 
clothed with golden scales. Head densely punctate, foveate between the eyes, which are widely 
separated; rostrum short, stout, sparsely punctate, shining. Prothorax transverse, conical, densely, 
very finely punctate. Elytra broad, subcordate, somewhat gibbous towards the base, separately rounded 
at the apex, the humeri rounded and moderately swollen, the infra-humeral prominence obtuse and feebly 
developed ; seriate-punctate, the interstices densely, minutely punctate. Beneath rather sparsely punc- 
tate. Anterior and intermediate femora acutely, and the posterior pair obscletely, dentate; all the tibiv 
finely setose along their inner edge. 
Length 10-114, breadth 53-7 millim. 
Hab. Panama, Volean de Chiriqui (Champion), Chiriqui (Trdésch). 
Three specimens. Easily recognizable by the two narrow golden fascie of the elytra, 
and the transverse, conical, very densely, finely punctate prothorax. 
8, Sternechus bicaudatus, sp. n. (Tab. VII. figg. 25, 25a, d.) 
Robust, subelliptic, black, slightly shining, clothed with very minute, scattered, hair-like scales, the legs witha 
few short hairs. Head closely punctate, foveate between the eyes, which are large and somewhat narrowly 
separated ; rostrum very stout, rather sparsely punctured. Prothorax transverse, a little flattened on the 
disc, very much narrowed and constricted in front and also narrowed behind, the sides rounded at the middle 
and obsoletely trituberculate ; the surface, except along a narrow smooth space down the middle, closely 
punctured, the punctuation becoming coarser and rugose towards the sides. Elytra subtriangular, seriate- 
punctate ; a subtriangular space occupying nearly the basal half of the dorsal surface a little raised and 
finely granulate, the rest of the surface flat and exceedingly minutely punctate; the fifth interstice with 
a long conical tubercle before the apex, the humeri much swollen and rounded, the apices separately 
tuberculate ; the infra-humeral prominence long and conical, swollen at the base. Anterior femora only 
armed with a short tooth before the apex; all the tibie denticulate along their inner edge, but without 
longer tooth. 
Length 14, breadth 7 millim. 
Hab. Panama, Bugaba (Champion). 
Very like 8S. tuberculatus, but with a long conical tubercle on the fifth elytral 
interstice before the apex, the apices themselves tuberculate, the humeri more rounded, 
the armature of the legs different, and the sculpture of the upper surface also, the latter 
being difficult to describe and perhaps abnormal in the single abraded example seen.
