238 SUPPLEMENT. 
Of the same shape and with similar characters to P. seminiger, excepting that the 
elytra are of an ochraceous yellow instead of brick-red and have no black at their apex. 
I only hesitate to consider it as a variety of that species, because differences of colour 
of this kind are usually specific characters in this family, and I have yet only been able 
to examine a single female specimen. 
Plateros bourgeoisi (p. 19). 
To the localities given, add :—MeExico, Oaxaca (Hége). 
Two specimens with the humeral stripe rather wider than in the type. 
Plateros evanidus (p. 20). 
Var. Pedibus testaceis, tibiis tarsisque infuscatis. 
Hab. Guatemata, Purula, Chacoj, Teleman, Mirandilla (Champion); Panama, Volean 
de Chiriqui, Bugaba (Champion). 
Plateros apicalis (p. 20). (Tab. XI. fig. 9, 2.) 
To the localities given, add :—Panama, Volcan de Chiriqui, Bugaba (Champion). 
The original description refers to the female; a large number of specimens of a 
Plateros which are, I believe, all referable to the same species have since been found 
by Mr. Champion, and present a peculiarity I have not observed before in this genus, viz., 
that while the females agree with the type in having the apical joints of the antenne 
pale, those of the males are (as far as I have yet ascertained) wholly black. 
The males are usually smaller than the females, four and a half to five millimetres 
in length; and the proportion of black on the elytra very variable—sometimes more 
than half the suture, sometimes only the apex. The ground-colour of the elytra is 
brown or sordid yellow; it is never brightly coloured. ‘The thorax has a deep puncti- 
form sulcus near the base—it often varies in length even in the same sex; and, unless I 
am deceived, the eyes are prominent, and the front of the head disclosed in some female 
specimens as much as in the males. In one female the antenne are black at the apex. 
This species, and P. luridus, were identified by me with specimens in my own col- 
lection so named by M. Bourgeois, but of which I believe no descriptions have been 
published. They are more parallel and longer species than their allies. P. evanidus 
has the body nearly always black. In P. apicalis the middle of the sterna between 
the coxe is sometimes, the scutellum rarely, yellow. 
Great numbers were taken by Mr. Champion. 
Plateros luridus (p. 20). 
To the localities given, add :—GuaremaLa, Purula, Chacoj (Champion); Panama, 
Bugaba (Champion).
