296 SUPPLEMENT. 
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 
Very nearly allied to 8. transfixa; smaller, and with the elytra grey, and the legs 
entirely red; also distinguished by the fulvous apical ventral and dorsal segments, and 
by the narrow pygidial plate being notched, thus exhibiting two points at the apex. 
Head wide, eyes prominent, antenne and mouth-organs entirely red. Thorax sub- 
quadrate, a little angularly widened at the sides, where, in the male, it is nicked a little 
below the middle. 
A small series was captured by Mr. Champion. 
Silis eroides (p. 94). 
To the localities given, add:—GuatTemaLa, San Gerénimo (Champion); Panama, 
Bugaba (Champion). 
Specimens of both sexes were captured at Bugaba ; the males of these have the edges of 
the thorax more deeply laciniate,and the hind lobe longer and more developed than in the 
type; the thorax therefore looks less orbiculate, and the incision being hairy and compli- 
cate they are not easily recognized; the antennz are very wide in the middle, the second 
joint is very short, and all the joints are hairy. ‘The specimens from Cordova, of which 
I have only seen two, one of which has yellow elytra with only the suture dark at the 
base, are not satisfactorily connected with this type. Both are, I think, females, and 
should, I believe, be referred to Silis lycoides. [Cf. note upon that species, Suppl. 
antea, p. 290. | 
Silis lineata (p. 95). 
To the localities given, add :—Panama, Volcan de Chiriqui, Bugaba (Champion). 
Typical male specimens have the thorax not orbiculate, but elongate, with the margins 
deeply sinuate; but the form and mode of plication does not seem quite constant. 
Many examples, mostly females, of a variety with yellow elytra with a dark sutural 
line at the base, and which seem more pubescent than others, occurred at 2500 to 4000 
feet altitude ; these closely mimic Plateros ochraceus, while some from Bugaba, as well 
as from the higher altitudes of Chiriqui, almost as nearly mimic P. bugabensis, and 
these have the elytra a little wider behind than usual, thus completing the illusion.
