PLATEROS.—CALLEROS. 25 
Fasily distinguished from P. mexicanus, which it otherwise rather closely resembles, 
by its quite red thorax. The red shoulder-stripe extends a little way down the humeral 
costa ; but the margins of the elytra are black to close to the base ; the alternate interstices 
are more sharply raised, in which respect this species rather resembles P. bourgeoisi. 
From that species the much shorter thorax, as well as its rosy-red colour, separates it. 
There are four female specimens in M. Sallé’s collection. 
20. Plateros patiens. 
Niger, prothorace elytrorumque dimidio basali testaceis, his interstitiis alternis regulariter elevatioribus, illo 
margine basali paulo elevato et exciso; antennis serratis ; femoribus basi flavis. Long. 9 millim. 
Hab. GuatEMALa, Zapote (Champion). 
A species very much resembling P. apicalis, from which it may be distinguished by 
the apical joint of the antenne being black, the thorax quite unicolorous, yellow, with 
the base elevated in the middle, so as to form a short double carina, on each side of the 
central channel. The scutellum is yellow; the yellow of the elytra continues along the 
margin further than at the suture. Only a single specimen appears to me to belong to 
this species. 
21. Plateros stramineus. 
Pallide testaceus, corpore, antennis pedibusque nigris, his basi testaceis, thoracis disco interdum fusco, breviter 
canaliculato, basi sinuata, integra, angulis posticis acutis, productis. Long. 54-6 millim. g 9. 
Hab. GuaTemMaa, San Gerénimo, San Juan (Champion). 
One of the smallest Platerotes, about the size of P. striatus, but readily distinguished 
by its yellow colour above. The elytra are very evenly striate, without elevated lines. 
The disk of the thorax is either marked with pitchy or is of the same colour as the rest 
of the upper surface. The central channel is wide, but vanishes in front and behind. 
Three specimens, collected by Mr. Champion. 
CALLEROS, 
Genus Plateroti affine, antennis gracilioribus, prothorace plerumque angustiore quam elytra, sulco basin vix 
attingente, et angulis posticis minus acute productis, mox distinguendum. 
Caput haud rostratum, oculis sat magnis, antennis subfiliformibus, vix serratis, parum compressis. Prothorax 
elytris plerumque basi angustior, disco inzequali ad basin canaliculato vel fossulato, angulis posticis subrectis 
vel muticis, margine basali integro. Scutellum apice fissum. Elytra postice paulo ampliata vel parallela, 
regulariter substriata, intervallis subtiliter rugosis vel crenulatis, pubescentia, interstitiis alternis vix vel 
haud elevatioribus. Abdominis segmentum penultimum maris ventrale emarginatum, dorsale oblique 
truncatum ; feminz ventrale conicum, apice fissum. 
A genus proposed to receive some small Lycide which are allied to Plateros, but 
differ considerably both in general appearance and, especially, in the long thin antenne. 
They are species of moderate size, with brightly coloured red thoraces and elytra, 
sometimes purplish or cochineal. I have taken the first species described below
