MALACODERMATA. 239 
Scutellum generally yellow, as well as the greater part of the breast, often also the 
femora. It is a longer species than P. rubricatus, and in addition has the apical joint 
of the antenne yellow. 
Taken in profusion at Bugaba. 
Plateros lateritius (p. 21). 
To the localities given, add:—Panama, Volcan de Chiriqui (Champion). 
Distinguished, among other characters, by the larger size, more widened elytra, wholly 
black body and appendages, and black vitta on the thorax. There is a specimen of, 
what I consider, a variety, taken by Mr. Champion in Chiriqui, which has the alternate 
coste more raised, the suture black, and the thoracic vitta divided. Dr. Leconte 
(Trans. Am. Ent. Soc. 1881, p. 26) confirms my conjecture that this insect is not the 
same as Lycus sanguinipennis, Say, which M. Bourgeois seemed to have considered to 
be a Plateros, but which is a rostrate species belonging apparently to Lycostomus. It 
would, however, be of little use to attempt to refer any particular species of Plateros 
to M. Bourgeois’s notice under that name; several closely allied species were contained 
in M. Sallé’s collection. 
8 (a). Plateros forreranus. (Tab. XI. fig. 8.) 
Flavo-testaceus ; antennis, vitta prothoracica, scutello elytrorum fascia subbasillari ad suturam latiori, trienteque 
apical, femorum apice, tibiis tarsisque nigris; abdomine picescente, basi in medio testaceo; antennis 
fortiter serratis. Long. 8-11 millim. ¢ Q. 
Hab. Mexico, Presidio, Ventanas (Morrer); Guatemata, San Isidro (Champion). 
Antenne acutely serrate, not differing perceptibly in the sexes. Hlytra moderately 
widened towards their apices. Heada little infuscate, antenne black. ‘Thorax with an 
indistinct carina in front, especially in the female, the central vitta not always prolonged 
to the front. Elytra ferruginous, paler in the middle, with a broad fascia touching 
the scutellum near the base, and the apical third smoky black. Body beneath, except 
the abdomen, testaceous. 
This is one of the most prettily marked species of the genus Plateros I have seen; 
it is like P. bogotensis, and distinguished from it by the much wider central yellow 
band across the elytra, and by the yellow body. ‘The specimen figured is from Presidio. 
Plateros terminalis (p. 22). 
To the localities given, add:—Panama, Volcan de Chiriqui, Bugaba (Champion). 
Near P. (Eros) canaliculatus, Say ; but with the antenne longer and wider, the apical 
joint yellow or fuscous. The thorax has no carina in front, but is rather irregularly 
rugose, the ruge in the middle being longitudinal; the channel is open behind, the 
base being thus emarginate in the centre.
