and Central American Telephoriiiae. 95 



Hab. Guatemala, Chiacam and Cubilguitz in Alta Vera 

 Paz. 



Two males, agreeing perfectly inter se. Gorham's de- 

 scription of Silis proxima, from Chiacam, was taken from 

 the female, the male provisionally referred to it by him 

 proving to belong to a different species now that both 

 sexes of P. proxifnus are definitely known. P. dentimargo, 

 in fact, comes very near P. {Silis) paupercidiis, Gorh., from 

 Chiriqui ; but it has the prothorax (of the male) less narrowed 

 behind, with the margins more distinctly notched at the 

 middle, and the deep oblique lateral sulci shallower and 

 straighter.

 Silis minuta, Gorh., Biol. Centr.-Am., Coleopt. iii, 2, p. 305 



Hab. Guatemala, Zapote, on the slope of the Volcan de 

 Fuego. 



P. (Silis) minutus is represented in the " Biologia " 

 collection by two males from Zapote, mounted by their 

 captor on the same piece of card, and labelled " type " 

 by Gorham. They belong to different species, but the 

 description can only have been made from one of them, 

 that with the whole of the anterior portion of the head 

 whitish and the femora testaceous to near the tip. This 

 specimen, the actual type, has the prothorax rufo-testaceous, 

 with a black median vitta and sharply defined whitish 

 margins, interrupted at the middle by an outward exten- 

 sion of the reddish coloration. It has the eyes small, but 

 prominent ; the antennae moderately long, with very short 

 second joint; the prothorax strongly transverse, hollowed 

 down the centre, with the reflexed margins plicate and 

 narrowly excised behind the middle, the lobe in front of 

 it rounded externally and not very prominent, the hind 

 angles rectangular ; the elytra parallel and roughly sculp- 

 tured. The somewhat similar Discodon (Silis) minuscidum, 

 Gorh., from the same locality, has the sides of the pro- 

 thorax of the male dilated anteriorly into a broad angular 

 lobe and the lateral excision broader and placed further 

 forward, the second antennal joint longer, the three tarsal 

 claws cleft, etc.
