and Central American Telephorinae. 87 



19. Polemius cephalotes. (Plate VIII, fig. 60, prothorax, (^.) 



Telephorus (Silis) cephalotes, Gorh., Biol. Centr.-Am., 

 Coleopt. iii, 2, p. 289 ((^ ?). 



1^. Head large, broad; eyes large; antennae very long, feebly 

 subserrate, tapering towards the tip; prothorax fully as long as 

 broad, narrow, the margins refiexed, obliquely plicate, deeply 

 angularly notched just behind the middle (appearing bluntly dentate 

 in front of this), and slightly hollowed before the hind angles; 

 elytra much broader than the prothorax, widening to the apex; 

 inner claw of anterior tarsi, and outer claw of the other tarsi, angu- 

 larly dilated at base. 



$. Head, eyes, mandibles, and antennae much as in ($, the eyes 

 a little less prominent; prothorax transverse, the margins tri- 

 sinuate, and thickened into a small blunt tooth at the middle, the 

 hind angles acute and prominent. 



Hab. Panama, Bugaba. 



One male and two females seen. A moderately elongate, 

 posteriorly widened form ; shining, piceous, with the head 

 (except on the middle of the vertex), the last two joints of 

 the antennae, the sides of the prothorax, the humeri, and 

 sometimes the base of the femora also, testaceous or yellow, 

 the elytra finely sculptured, the head large in both sexes, 

 the prothorax elongate and with the sides deeply angularly 

 notched at about the middle in the male, the legs slender. 

 P. cephalotes bears some resemblance to Discodon plicatum, 

 Gorh., but the latter has two of the tarsal claws cleft in 

 the male. 



20. Polemius sallaei. 



Silis sallaei, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, p. 303. 



■^. Eyes large ; antennae elongate, slender ; prothorax nearly as 

 long as broad, obliquely grooved on each side anteriorly, the margins 

 narrowly refiexed, angularly dilated at about the middle and sub- 

 parallel thence to the acute hind angles; inner claw of anterior 

 tarsi, and outer claw of the other tarsi, angularly dilated at base. 



$. Eyes smaller; antennae a little shorter; prothorax more 

 transverse, more narrowed anteriorly, the margins simply trisinuate. 



Hab. Mexico, Cordova {Salle : (^ $) ; Guatemala, 

 Senahu in Alta Vera Paz (Champion : $).
