and Central American Telephorinae. 127 



dilated into a blunt tooth in front of this, and rounded, convex, 

 and almost immarginate from the notch to the base ; tibiae curved ; 

 tarsal claws as in P. colyphoides. 



$. Prothorax smaller and shorter, rounded and feebly bisinuate 

 at the sides, the margins narrowly reflexed throughout. 



Hab. Panama, Bugaba, Volcan de Chiriqui. 



Redescribed from the types, male and female. Smaller 

 than P. colyphoides, the legs more slender, the head between 

 and behind the eyes, the prothorax across the middle, and 

 the apices of the femora, tibiae, and tarsi piceous or black ; 

 the elytra coarsely punctate, piceous or nigro-piceous, with 

 an oblique stripe running down the disc, and the outer 

 margin and apex also in the male, testaceous. The tip 

 of the abdomen of the male is injured, but the last dorsal 

 segment appears to be drawn out in a lobe on each side 

 beneath (as described by Gorham), much as in P. coly- 

 phoides. 



Malthaster.

 (1885). 



This genus is based upon a single species, M. suturalis, 

 from the mountains of Chiriqui. To the characters given 

 by the author, the following may be added : — Prothorax 

 obliquely grooved on each side before the middle, the 

 margins triangularly notched in ^ and sinuate in $ (as in 

 Parasilis, etc.). The tarsal claws and mandibles are 

 simple. The elytra are very long, soft, and completely 

 cover the wings and abdomen. The cleft seventh * 

 ventral segment and the notched margins of the prothorax 

 of the male bring Malthaster near Parasilis, Discodon, 

 Polemius, etc.

The symmetrical genital armature of the male is figured 

 on Plate VI, figs. 38, 38a, b, and the prothorax of a specimen 

 of this sex on Plate IX, fig. 100.
