and the genus should, I think, therefore be placed in the 

 Magdalina3. 



Cholus Oherthurii. 



C. oblougus, fiiscus, nitidus, maculis niveis parvis adspersus ; rostro 

 ferrug'ineo, in medio carinato ; prothorace transversim subtiliter 

 granulate. Long. 7 lin. 



Hah. Santo Paulo d'Olivenya (Upper Amazon). 



Oblong, glossy dark brown ; rostrum smooth, ferruginous, 

 with a well- marked ridge in the middle ; antennas pitchy, 

 scape moderately long ; prothorax subtriangular, marked with 

 delicate transverse linear granules, the intervals with a few 

 punctures and scattered silaceous scales, some condensed on 

 each side, forming three or four spots ; scutellum oblong, 

 rounded at the apex ; elytra slightly depressed at the base, 

 seriate-punctate, the interstices marked with narrow transverse 

 interrupted raised lines, and numerous small distinct silaceous 

 spots ; legs ferruginous, nearly glabrous ; body beneath 

 closely covered with yellowish silaceous scales. 



Allied to C. Buckleyi^ a more convex species without a 

 rostral carina, a minutely punctured prothorax, and otherwise 

 sculptured. Named after M. Rene Oberthiir, of Rennes, to 

 whom I am indebted for this and other interesting forms. 



Cholus megaspilus. 



C. oblongns, niger, nitidus ; elytris maculis niveis raajusculis ornatis ; 

 antenuis articulis duabus basalibus funiculi brevibus ; scutello 

 angusto. Long. 7 lin. 



Hab. Sarayacu (Peru). 



Oblong, black, glossy ; rostrum smooth, with two diverging 

 grooves at the base ; antennae moderately long, the two basal 

 joints of the fnnicle short ; prothorax minutely punctured ; 

 scutellum narrowly oblong; elytra convex, seriate-punctate, 

 punctures minute, on each four or five round depressions filled 

 with snow-white scales ; body beneath and legs smooth. 



Closely allied to C. nitidicollis^ but with shorter antenna?, 

 oblong scutellum, the elytra more convex and with fewer and 

 larger spots. 



Cholus canescens. 



C. anguste subelliplicus, paulo convexus, castaneus, squamulis pal- 

 lide silaceis sejimctim vestitus ; elytris seriatim puuctatis, inter- 

 stitiis conformibus ; mesosterno deprcsso. Long. 4 lin. 



Hab. Panama.
