MR. F. P. PASOOE ON THE CURCULIONIDiE. 471 



In this and the preceding species the unguiculus, or hook, at 

 the apex of each tibia appears to be absent ; on close examina- 

 tion, liowever, it can be seen amidst the hairs which occupy 

 that part of the tibia. 



EUETIIISTES, 



(Choliuai.) 



A Periderceo differt lohis ocularibus nullis, tibiis anticis baud un- 

 guiculatis. 



Lacordaire lias already pointed out that three of Schonherr's 

 CJioli have the characters of Periderosus, with the exception of 

 the two given above ; Periderceus itself is only separated from 

 Cholus by the length of the posterior femora, which extend 

 beyond the elytra. The three Clioli to be referred here are 

 lateralis, tetricus, and silaceo-guttatus ; four more are described 

 below, only one of which, JE. congesius, can be said to have an 

 obvious affinity to any one of the others (to G. tetricus, Eabr.) . 

 I have another species from Minas closely allied to the latter. 



Erethistes leucospilus. E. anguste ovatus, nitide niger, infra 

 dense albido-squamosus, prothorace nigro-olivaceo ; elytris albo-pla- 

 giatis ; capite rostroque basi griseo-squamosis ; antennis ferrugineis ; 

 funiculi articulo primo duobus sequentibus conjunctim baud longiore, 

 tribus ultimis transversis ; prothorace antice multo angustiore, supra 

 subgranulato, subtiliter punctulato ; scutcllo scutiformi ; elytris pro- 

 thorace baud latioribus, sat fortiter seriatim punctatis, scricbns 

 subapproximatis, singulis cavitatibus quatuor squamis albis repletis 

 ornatis ; pedibus nigris. Long. 5 lin. 



Hab. Cayenne. 



Like E. ochriventris in outline, only a little narrower, but with 

 a coloration after the style of Cholus ICunzei. 



Erethistes licheneus. (PI. XI. fig. 6.) E. anguste aubrhombicus, 

 totus niger nitidus, plagis ad latera albido-squamosis exceptis ; rostro 

 basi crassiore, in medio compresso ; scrobibus ultra medium rostri 

 baud extensis ; scapo antennarum apicem versus sat fortiter arcuato ; 

 funiculo elongato ; clava ovali ; prothorace longitudine latitudini fere 

 sequali, irregulariter sat confertim granulato, inter granula subtilis- 

 sime mamillato-punctato (granulis etiam puncto singulo margine 

 anteriore impressis); scutello transversim rotundato; elytris suboo- 

 nicis, remote seriatim punctulatis, subcorrugatis, singulis plagis duabus 

 lateralibus, anteriore permagna, e squaniulis flavidulis, margine den-
