PLATEROS. 21 
antennee and the elytra adorned with obscure dark dashes in the intervals of the 
coste. 
7. Plateros lateritius. (Tab. II. fig. 16, ¢ .) 
Niger, prothoracis lateribus elytrisque sanguineis; illo basi profunde sulcato, antice carinato; his punctato- 
striatis, interstitiis parum elevatis. Long. 9-113 millim. ¢ 2. 
Hab. Mexico, Cordova, Oaxaca (Sailé). 
Head, antenne, body, legs, scutellum, and the disk of the thorax black. The elytra 
and sides of the thorax of a fine brick-red, the former sometimes with the base of the 
suture black, the latter inclining to orange-red. The antenne are compressed, serrate, 
the joints from the third to the tenth a little longer than wide, but decreasing in width 
towards the apex ; the apical joint much narrower than the tenth. The rows of punc- 
tures are ten in number, the alternate interstices a little more raised than the others. 
According to Sallé’s collection this is Cenia sanguinipennis, Say. I think, however, 
that will prove to be a different insect, the present species having nothing to do with 
the genus Cenia. 
8. Plateros bogotensis. (Tab. II. fig. 18.) 
Eros bogotensis, Kirsch, Berl. Zeits. 1865, p. 67°. 
Hab. Guatemara (Sallé).—Soutn America, Bogota 1. 
A specimen of this species in M. Sallé’s collection, since acquired by Messrs. Godman 
and Salvin, agrees with one which was thus named by M. Bourgeois in my own 
cabinet. 
9. Plateros thoracicus. 
Nigro-piceus, capite, prothorace (disco excepto), elytrorum vitta humerali cum fascia ad suturam et marginem 
latiore conjuncta, pedibusque basi flavescentibus ; thorace subquadrato, antice prominulo ; elytris parallelis, 
punctato-striatis. Long. 8-9 millim. 
Hab. Nicaragua, Chontales (Belt, Janson); Panama, Matachin (Thieme).—Sovtu 
America, Colombia. 
Very near to P. bogotensis, but apparently distinct, being smaller, with the yellow 
portions of the elytra frequently more extended, occupying almost the whole base. 
There is usually a large basal blotch common to both elytra, of a trapezoid form, and 
with about a third of its apex smoky black. The thorax exhibits an angle on each 
side in front; the front itself is prominent, but truncate; the carina in front is 
minutely divided or channelled. 
10. Plateros isthmianus. 
Nigro-fumosus, prothorace elytrorumque humeris, pedibus basi et pectore plus minusve flavescentibus ; thorace 
subquadrato, fronte emarginata basi canaliculata; elytris substriatis, coriaceis, lineis quatuor elevatioribus. 
Long. 74-83 millim. ¢ Q.
