than the prothorax, subcordate, the humeri rounded and prominent, the anterior margin raised ; crenate- 
striate (the strie shallow, the punctures large and deep), the interstices slightly rugulose, 3, 5, 7,9 from 
the base to the apex, 8 and 10 at the base, and the suture also, sharply costate, the other interstices fiat. 
Legs stout ; intermediate and posterior tibize sharply angulate externally and ciliate thence to the apex. 
Length 62-94, breadth 32-5 millim. (d 9-) 
Hab. Mexico, Jalapa (Hége); Panama, Volcan de Chiriqui (Champion). 
Described from a pair from Jalapa, the single specimen (2) from Chiriqui being 
much larger, smoother, and more sparsely pubescent, and having the prothorax 
emarginate in the centre in front. The contiguous eyes, the feebly carinate prothorax, 
the less oblong elytra, and the more abundant pubescence separate it from R. acute- 
costatus. 
7. Rhyssomatus latus, sp.n. (Tab. XVII. figg. 18, 154, ¢; 18 8, interm. 
tibia.) 
Short, broad, rhomboidal, shining, black, slightly mottled with rufo-piceous, the scape of the antenne 
ferruginous, sparsely pubescent. Head densely, finely punctate, the eyes contiguous ; rostrum feebly 
curved, rather slender, nearly twice as long as the prothorax, closely punctate, pluri-carinate in its basal 
half, the antenne inserted a little behind the middle. Prothorax at the base more than twice as broad 
as long, conical, strongly constricted in front, the base subtruncate; closely, obliquely strigose and finely, 
shallowly punctate, the dise with a median carina extending from the apex to near the base. Elytra 
broad, subtriangular, slightly wider than the prothorax at the base and dilated at the sides beneath the 
prominent humeri; seriato-foveolate, the foves oblong in shape, the interstices slightly rugulose, 
3,5, 7,9 from the base to the apex, 8 and 10 at the base, and the suture moderately, costate. Meso- 
sternum protuberant anteriorly. Legs short and moderately stout; intermediate and posterior tibiz 
sharply angulate externally and ciliate thence to the apex. 
Length 53, breadth 34 millim. (2.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. The short, subtriangular elytra, with moderately costate alternate 
interstices, the short, conical, posteriorly dilated prothorax, the long rostrum, and the 
short legs are the chief characters of this species. 
s. Rhyssomatus latipennis, sp.n. (Tab. XVI. figg. 19, 19 a, 2.) 
Short, broad, subrhomboidal, shining, black, mottled with rufo-piceous, the antenne, rostrum, and tarsi 
ferruginous, very sparsely pubescent. Head densely, finely punctate, the eyes separated by nearly half 
the width of the rostrum ; rostrum curved, stout, about as long as the head and prothorax, rugulosely 
punctate, becoming smoother and more shining towards the tip, the antenne inserted at the middle. 
Prothorax conical, short, at the base twice as broad as long, strongly compressed at the sides anteriorly, 
the base subtruncate ; densely, finely punctate, the punctures separated by very narrow, oblique rugz, the 
dise with a fine median carina, which does not reach the base. Elytra much wider than the prothorax, 
feebly dilated at the sides beneath the rounded, prominent humeri, and narrowing thence to the apex ; 
seriato-foveolate, the interstices slightly rugulose, 3, 5,7 very sharply costate throughout, and 8 at the 
base, and 9 and 10, more feebly costate, the others flat, the suture also raised. Mesosternum not 
protuberant. Legs short and rather slender ; intermediate and posterior tibiee feebly angulate externally 
and ciliate thence to the apex. 
Length 34, breadth 23 millim. (.) 
Hab. Guaremata, Cerro Zunil 4000 feet (Champion).
