CEMCHRESTUS. 203 



fulvous spots at the inner and upper margin of the eyes. Thorax 

 quadrate, depressed in front, slightly constricted at the apex ; sides 

 finely marginate, and in form subsinuate ; at the base (when viewed 

 laterally) is a deep and distinctly defined transverse fovea ; the sur- 

 face is dark fuscous, the lateral margins being broadly fulvous. 

 Scutellum triangular, impunctate, fuscous-black. Elytra somewhat 

 broader than the thorax, subelongate and parallel, deeply punctate- 

 striate, and (when viewed under a high power) very finely covered 

 with short obsolete fuscous pubescence. Antennas robust, subfiliform, 

 fuscous. Legs fuscous, the femora being suffused with flavous. 



C. Chevrolatii differs from C. exiguus (to which it is most nearly 

 related) by its very parallel and subcylindrical elytra, as well as by 

 the absence of any flavous marking near the humeral angles. 



South America. In the collection of M. Chevrolat. 



8. Cerichrestus humilis. 



C. oblongo-ovalis, parallelus, subdepressus, punctato-striatus, sub- 

 tiliter pubescens, fusco-niger ; capite brevi, clepresso, granulato, 

 antice flavo, ad basin nigro ; thorace transverso, ad basin sub- 

 coarctato et transverse depresso, subtiliter pubescenti, Jlavo, ad 

 medium fusco adumbrato ; elytris depressis, punctato-striatis, 

 obsolete fusco-pubescentibus ; antennis filiformibus, sat robustis, 

 nigris ; pedibus Jlavis, tibiis tarsisque fusco adumbratis. 



Long. corp. 2\ lin., lat. 1 lin. 



Oblong-oval, somewhat depressed, parallel, punctate-striate, finely 

 clothed with obsolete fuscous pubescence, fuscous. Head short, 

 vertical, slightly produced in front ; below the insertion of the an- 

 tennas is a transverse triangular depression, at the base of the antennas 

 the surface is obsoletely raised ; the base of the head is coarsely 

 granulated, and in colour black ; the eyes are large, globular, lateral, 

 and situated at the base of the head. Thorax transverse, rectangular ; 

 the sides are at the base slightly constricted and marginate ; at the 

 base is a broad transverse depression; the surface is equate and 

 thickly pubescent; the colour is flavous, being, medially, broadly 

 adumbrated with fuscous. Smtellum minute, fuscous. Elytra broader 

 than the thorax, depressed, parallel, punctate-striate (the punctures 

 being obsolete, and the striae deep), and clothed with a minute, but 

 thick, fuscous pubescence ; the colour dark fuscous. Antennce fili- 

 form, tolerably robust, black. Legs flavous, more or less clouded 

 with fuscous. 



C. humilis differs from most of the species in the group by the 

 absence of markings on the elytra ; and from those which, like it,
