Plateros PALLiATtrs, sp. n. 



Plateroti forrerano GorJi. affinis et summa similitudine ; niger, 

 prothorace et elytris I<ete jJavis, his macula magna suhhasali, 

 communi hasin attingente (humeris et marginihus Jlavis), et 

 quadi-ante apicali nigris. Long. 9—10 millim. 5 • 



Hab. St. Vincent (B. H. Smith). 



Head, body with the legs, and antennae entirely black. The 

 thorax yellow, wider at the base than its length, the central 

 channel deep, the disk irregular, with ridges running obliquely 

 from the raised edges of the channel from the base and middle, 

 the frontal carina not defined. The elytra have the shoulders 

 rather widely yellow, and narrowly joined with a broad yellow 

 posterior fascia, narrowed on its basal side towards the suture. 

 The black subbasal patch is thus broadly cruciform, differing from 

 that in P. forreranus (a Central-American species) in being 

 joined to the base, and in being further extended down the suture. 

 The scutellum is black. This insect very closely resembles 

 P. forreranus Gorh. Biol. C.-Am., Col. vol. iii. part ii. p. 239, 

 Suppl., but there are important dilferences which cannot be 

 overlooked. 



PlATEEOS FEATEENirS, Sp. n. 



Niger, prothorace nitido, scutello et elytris Jlavis, his basi triente et 

 quadrante apicali nigro-fumosis. Long. 7*5-8 millim. 



Hab. St. Vincent {H. H. Smith). 



The antennae in this species are scarcely serrate ; the thorax 

 and scutellum yellow, and both shining, the former transversely 

 square, with a rather prominent and elevated front margin. The 

 channel and oblique ridges distinct but ill-defined. The elytra 

 very evenly striated, and the punctures distinct. The basal black 

 covers the whole base except the extreme reflexed margin, and its 

 apical side is rounded, but not regularly, as the blackness extends
