STERNECHUS.—PISSODES. 119 
12. Sternechus bicinctus, sp. n. (Tab. VII. figg. 28, 28 a, 0.) 
Subelliptic, broad, robust, shining, black, the antenne and tarsi sometimes obscurely rufescent; the upper 
surface somewhat sparsely clothed with coarse, narrow, ochreous scales, the elytra with two rather broad 
fasciee of coarser, white, closely-placed scales—one before and the other beyond the middle, the anterior 
one widening outwards and interrupted at the suture; beneath sparsely squamose, the squamosity at the 
sides coarse and ochreous in colour, and piliform and whitish along the middle; the legs with narrow 
white scales and long hairs. Head closely punctate, shallowly foveate between the eyes, which are 
narrowly separated; rostrum short and stout, sparsely, very finely punctate. Prothorax strongly trans- 
verse, rounded at the sides, narrowing almost from the base and constricted in front, the lateral margins 
slightly crenulate ; the surface closely, somewhat coarsely punctate. Elytra broad, subcordate, gibbous, 
conjointly rounded at the apex, the humeri rounded and moderately swollen, the infra~-humeral prominence 
almost obsolete; seriate-punctate, the interstices sparsely, minutely, rugulosely punctate. Beneath 
sparsely punctate. Femora unarmed; tibie finely cetose along their inner edge. 
Length 114-13, breadth 63-74 millim. 
Hab. Nicaracua, Chontales (Belt); Panama, Bugaba (Champion), Chiriqui (Trétsch). 
Three specimens. Very like the Mexican S. bifasciatus, but more shining; the 
squamosity much coarser, and (except upon the fasciz) ochreous in colour ; the fascie 
broader, the anterior one widening outwards ; the head very shallowly foveate between 
the eyes; the infra-humeral prominence almost obsolete. 
13. Sternechus pollinosus. (Tab. VII. figg. 29, 29 a, 0.) 
Tylomus pollinosus, Bob. in Schénh. Gen. Cure. vil. 2, p. 364". 
Hab. Mextco!, Sierra de Durango (Flohr), Mineral de la Luz, Puebla (Sal/é), 
Xucumanatlan in Guerrero (H. H. Smith), Mexico city, Jalapa (Hoge). 
In fresh specimens of this species the piliform cinereous squamosity is somewhat 
condensed in places, forming three lines on the prothorax, a line down the suture, and 
two faint, oblique fascize on each elytron. The legs are pilose; the tibiz in the male 
armed with a very small median tooth.
