Hab. Panama, Volcan de Chiriqui. 



Recognisable by the rufo-testaceous head, palpi, antennae, 

 prothorax, and scutellum, and black elytra, the legs partly 

 or almost entirely infuscate, the anterior femora at the base 

 and the tibiae and tarsi at most testaceous. Eyes ex- 

 tremely large in (^, smaller in $. Mandibles curved in 

 both sexes. Antennae slender. Prothorax of the male 

 plicate and angularly dilated at the sides, with a slender 

 outwardly-curved tooth in front of the very narrow, 

 oblique, deep, post-median notch; that of the female 

 angularly dilated at the sides beyond the middle and with 

 the hind angles acute, the margins thus appearing strongly 

 trisinuate. Represented in the " Biologia " collection by 

 two males and one female.

Hah. Panama, Volcan de Chiriqui, 4000-6000 ft. 



An elongate, narrow, finely pubescent insect, with 

 testaceous head, palpi, antennae, prothorax, scutellum, 

 and legs, and plumbeous elytra ; the eyes large {^) ; the 

 prothorax {^) rounded at the sides, the reflexed margin 

 with a very narrow, straight notch behind the middle, 

 thus appearing angulate in front of the excision ; the 

 elytra finely sculptured; the eighth dorsal segment 

 ( = pygidium of Gorham) {(^) divided into two long narrow 

 lobes. The less angulate, more sharply notched sides of 

 the prothorax, and the smaller eyes, etc., of the male 

 separate S. fulvipes from S. transfixa. The nine examples 

 placed by Gorham under the present species are all of this 

 sex, but a single female left by him under S. transfixa 

 probably belongs here : it has the intermediate joints of 

 the antennae and the femora infuscate, the mandibles bent 

 (instead of curved), the margins of the prothorax thickened,
