rounded at the sides, carinate, and unequally punctate; the scutellum rather large; 

 the elytral interstices convex and subsinuate at the base.

Very elongate, depressed, rather broad, rufo-pieeous (? immature), moderately shining. 



Head somewhat 



exserted, rather small, longitudinally foveate between the eyes, and feebly constricted on each side 

 behind them, the interocular space and vertex closely punctate, the eyes large and somewhat depressed; 

 rostrum very short, abruptly, transversely, trapezoidally dilated at the apex, sharply sulcate between the 

 points of insertion of the antennae, closely punctate, the pterygia rounded ; antennae stout, with a large, 

 ovate club. Prothorax transverse, rounded at the sides, narrowed and constricted in front, moderately 

 bisinuate at the base ; closely, coarsely, irregularly punctate, the disc flattened and with abroad, shallow, 

 elongate-triangular depression extending forwards to the transverse subapical constriction, the flattened 

 space more finely punctate externally and with about three irregular rows of larger impressions on each 

 side of the smooth raised median line. Scutellum rounded. Elytra scarcely wider than the prothorax, 

 elongate, subparallel ; coarsely crenate-striate, the punctures rounded and closely placed, the interstices 

 obsoletely uniseriate-punctate, narrow, the outer ones raised. Beneath coarsely, rather 

 punctate ; ventral segments 1 



and 2 broadly depressed down the middle, 5 ochreo-pilose along the 



apical margin.

Hah. Panama, Volcan de Chiriqui 3000 feet (Champion). 







One male, probably not quite mature. An elongate, depressed form, with the 

 strum very short, narrowly and sharply sulcate between the points of insertion of 







nnse, and abruptly trapezoid 

 and closely punctured on the 



tip 



foveate 



prothorax rather short, longitudinally 



depressed and 



ery coarsely punctate down the middle ; the elytra elongate 



and 











coarsely crenate-striate. 



a 



head smaller, the rostrum 





differently shaped, the prothoracic depression shallower at the base, &c. 







18. COSSOIIUS planus, sp. n. (Tab. II. figg. 25, 25 a.) 



Elongate, broad, depressed, moderately shining, black, the extreme base of the antennae, and sometimes the 

 tarsi also, ferruginous. Head somewhat exserted, foveate between the eyes, the interocular space and 

 the exposed basal portion densely punctate, the eyes prominent ; rostrum short, broadly, transversely 

 dilated at the apex, the basal portion rather narrow and longer than the apical, densely punctate. 

 Prothorax transverse, rounded at the sides, constricted and much narrowed in front, deeply bisinuate at 

 the base ; closely punctate, the disc with an elongate-triangular, carinate, more coarsely punctured area 

 extending from the base to the subapical constriction. Scutellum rather large, subquadrate, flat. 

 Elytra moderately long, much wider than the prothorax, subparallel, flattened on the disc; with rows of 

 closely packed, moderately coarse, transverse punctures, separated by narrow, feebly uniseriate-punctate, 

 raised interstices, the latter becoming wider and flatter towards the suture. Beneath closely punctate ; 

 ventral segments 1 and 2 hollowed down the middle in the tf, broadly flattened in the <j> . Anterior 

 coxae separated by about their own width. 



Length 5-7, breadth lf-2f miliim. ( d $ .)
