and Central American Telephorinae. Ill 



(^. Eyes large ; antennae long, feebly subserrate, rather slender, 

 scarcely narrowed towards the apex; prothorax (fig. 80) narrow, 

 subcampanulate, with a rather broad, very deep, abrupt notch on 

 each side towards the base, the dilated margins drawn out into a 

 long, curved, oblique dentiform prominence in front of the excision 

 and an oblique subtriangular lamella behind it, the latter sub- 

 truncate and feebly emarginate at the tip, the hind angles obliter- 

 ated ; inner claw of anterior tarsi, and outer claw of the other tarsi, 

 somewhat dilated at the base. 



$. Eyes much smaller; mandibles curved; antennae short, 

 very stout, joints 3-1 1 broadly dilated, becoming gradually narrower 

 towards the apex ; prothorax (fig. 81 ) broader, transverse, narrowing 

 from the base, the margins strongly trisinuate, the hind angles 

 prominent.

Gorham (loc. cit. p. 290) correctly surmised that S. 

 praemarsa was the male of his S. lycoides, more especially 

 as the two sexes were obtained at the same locality, Cerro 

 Zmiil. This Lyciform insect is separable from its allies 

 by the posteriorly dilated, strongly costate elytra, and 

 opaque upper surface, the peculiarly notched prothorax, 

 uncleft tarsal claws, and large eyes of the male, etc. The 

 ochreous humeral patch of the elytra, and the median 

 vitta of the head and prothorax, varies in development, 

 the rest of the body being black. One male and three 

 females seen. A female from Cordova, Mexico, with more 

 feebly costate, almost wholly ochraceous elytra, treated by 

 Gorham as a variety of S. lycoides, probably belongs to a 

 different species.

cj. Eyes very large (together with the head broader than the 

 prothorax); antennae long, joints 3-11 moderately dilated, subser- 

 rate, slightly tapering outwards, densely set with short projecting 

 hairs ; prothorax transverse, small, uneven, rugose, the margins 

 reflexed, plicate, abruptly dilated at the middle into a curved, back- 

 wardly-directed lobe, very narrowly and obliquely notched behind 

 this, and with the inferior edge dilated into a narrow subtriangular 

 lamella exterior to the obtuse hind angles ; elytra much wider than
