78 PHYTOPHAGA. 



species is almost perpendicularly elevated, the top of the elevation being narrowly 

 divided by a deep groove. The figure is from the specimen from Oaxaca. 



8. Chlamys maculipes. (Tab. V. fig. 10.) 



Chlamys maculipes, Chevrol. Col. Mex, Cent. ii. 1835 ; Lacord. Mon. p. 660 1 ; Dejean,Cat. 3rd ed. 

 p. 440. 

 Hab. Mexico \ Panistlahuca, Cuernavaca, Cordova, Tehuantepec (Salle) ; Nicakagtja, 

 Chontales (Jansori). 



This species is not uncommon in Mexico, and varies much in shape and size, some 

 specimens being narrowed posteriorly, while others are nearly square. The same is 

 also the case in regard to the thorax, the latter varying in length and breadth. The 

 species may always be recognized by the two black spots of the thorax, which are 

 denuded of hairs. The specimen figured here is from Chontales. 



9. Chlamys insularis. (Tab. V. fig. 12.) 



Subelongate, robust, black or black and fulvous below and above ; thoracic elevation moderately raised, divided 

 and three-tuberculate above ; elytra deeply punctured, each elytron with about ten tubercles, the inner 

 sutural one in the shape of a transverse high curved ridge. 



Length If- 2 lines. 



Head fulvous, more or less stained with black, distinctly but not very closely punctured ; antennae entirely 

 fulvous, from the third joint to the apical ones transverse ; thorax transverse, anterior portion almost per- 

 pendicular, posterior elevation moderate, broadly divided at the top, each side of the division with three 

 triangularly placed tubercles or thin ridges ; surface irregularly but rather deeply covered with brown 

 punctures, anterior margin broadly fulvous or testaceous, a triangular patch of the same colour situated 

 in front of the scutellum ; the latter smooth, fulvous, margined with black ; elytra narrowed from the 

 middle to the apex, closely covered with deep, somewhat elongate punctures ; each elytron with the 

 following isolated and acute tubercles : — four placed parallel and close to the sutural margin, the second 

 of which consists of a transverse sharp ridge, the outer side of which is slightly curved upwards or 

 rather extended a little distance towards the base, the middle of which is occupied by a large tubercle ; 

 two others are placed posteriorly — a small one below the transverse sutural ridge, and a large pointed 

 one near the apex placed outwards at the extreme lateral margin ; the latter is accompanied at the middle 

 by another short curved ridge, in front of which two or three more or less distinct tubercles are visible : 

 pygidium distinctly punctured, fulvous, variegated with darker colour, with a very distinct central ridge 

 and several lateral depressions ; underside foveolate-punctate ; legs with a piceous central patch or entirely 

 fulvous. 



Var. Above entirely black, only the anterior part of the thorax and part of the legs spotted with flavous. 



Hab. Mexico, Playa Vicente, Cordova, Juquila (SallS). 



The nearest ally to this species seems to be C. nodosa and also C. venusta, 

 from both of which either colour or differently placed and shaped elytral tubercles 

 divide it. Six specimens are before me for comparison, one of them from the collection 

 of Mr. Baly, marked Mexico, and collected by Pilate. The figure represents a specimen 

 from Juquila.
