Platydema sexnotatum, Chevr. Petites Nouv. Ent. ii. p. 194°. 
Hab. Mexico! (coll. F. Bates), Cordova (WSallé), Jalapa (Hoge); Nicaragua, 
Chontales (Belt). 
_ This species will be readily identified by its ferruginous colour and elytral markings ; 
it varies in size from 52-7 millim. P. sexpunctatum, Chevy. (op. cit. p. 181), from 
Bogota, judging from the description, though apparently smaller (44 millim.), must be 
very Closely allied to, if not identical with, this species; if this should prove to be the 
case, the name seanotatum will have to be changed. 
An example from Cordova is figured.
