Zetheus. 

 (Calandrinae.) 



Megaprocto congruit, sed scrohihus basalibus, elytris parallelis, et 



femoribus elongatis gracillimis. 



It is to this species that Lacordaire probably alludes in the 

 note t. vii. p. 282. The geuus, so far as it is represented by the 

 following species, approaches to some undescribed forms of Pro- 

 dioctes in coloration. 



Zetheus electilis. (PI. IV. fig. 1.) Z. angustus, rufo-ferru- 

 gineus, supra indumento albido guttatim notatus; rostro paulo 

 arcuato, nitide fenugineo; scapo modice elongato; funiculo articulo 

 secimdo quam primo longiore ; clava obovata ; prothorace latitudine 

 sesquilongiore, utrinque rotundato, guttis albidis insequalibus h-regu- 

 lariter adsperso ; scutello nitide nigro ; elytris latitudine duplo lon- 

 gioribus, supra depressis, obsolete striatis, guttis albis minoribus 

 seriatim obsitis, singulis postice macula magna nigra albo marginata 

 ornatis ; pygidio elongato-conico, acute ; corpore infra obscure 

 albido-guttato ; pedibus fere nudis ; femoribus infra acute dentatis.

Pebiphemus. 



(Calandrinae.) 



Rostrum breviusculum, tenuatum, parum arcuatum, eylindricum ; 

 scrobes basales. Oculi transversi, ad prothoracem hand approxi- 

 mate Scopus breviusculus, basi rostri insertus ; clava parte 

 spongiosa obtecta. Prothorax oblongus, cylindricus. Scutellum 

 elongatum. Elytra parallela, prothorace baud latiora. Pygi- 

 dium declive. Femora postica elongata sublinearia, intermedia 

 breviora, antica compressa incrassata, omnia infra mvxtica ; tibice 

 sulcatge ; tarsi articulis tribus basalibus infra spongiosis ; 

 unguiculis parvis, approximatis. Corpus angustum, eylindri- 

 cum. 



The cylindrical form, the short slender rostrum with its basal 

 scrobes, and the spongy part of the club concealed, trenchantly 

 dilFerentiate this genus. The three species composing it are 

 homogeneous in point of form and colour, but differ essentially in 

 sculpture as well as in other characters. 



Periphemus retrorsus. (PI. IV. fig. 3.) P. nigrescens, lineis 

 griseo-tomentosis puuctisque squamositate grisea repletis ornatis ;
