at the sides and a feeble central ridge, the apex of the tibisB and 

 tarsi more or less fulvous. 



Hah. Peru. 



A small species, principally distinguished by the very highly 

 raised and deeply canaliculate posterior portion of the thorax 

 in connection with the obscure general cupreous colour. 



Chlamys indica, sp. n. (Plate XIV. fig. 9.) 



Subqnadrate and broad, black, opaque ; the basal joint of the 

 antennae, the labrum, the anterior femora, and the tarsi fulvous ; 

 thorax finely rugose, the middle portion but moderately raised with 

 longitudinal sinuate ridges ; elytra more strongly rugose, with a 

 central transverse and compressed tubercle at the middle and 

 another below the latter, and some longitudinal short tubercles at 

 the base and near the apex ; pygidium tricarinate. 



Length 2| lines. 



Head flat, variegated with black and fulvous, closely and finely 

 pnnctured, each puncture provided with a short yellow hair ; 

 labrum and palpi fulvous ; antennae fuscous, the basal joint fulvous ; 

 thorax very closely punctured, the sides with a small callosity, the 

 middle portion very moderately and obliquely raised, narrowly 

 sulcate at the top of the posterior portion, with two sinuate but 

 little raised ridges running downwards at each side towards the 

 anterior margin, the inner one of them forms the limit of the 

 median sulcus above ; scutellum finely carinate ; elytra wath the 

 suture crenulate throughout, the middle of the base with a com- 

 pressed tubercle, a sinuate ridge runs parallel with the suture from 

 the base and ends below the middle in another strongly raised 

 transverse tubercle, a similar tubercle precedes the latter one at 

 the middle of the outer disc and forms a ridge which extends 

 upwards to the shoulders, a third and less strongly marked ridge 

 is placed near the lateral margins, the apical portion of the elytra 

 is occupied by another semicircular strong ridge, which is highly 

 raised near the suture, from where it turns outwards and is lost near 

 the margins, the interstices between all these ridges are strongly 

 rugose or uneven ; the breast closely rugose-punctate, the anterior 

 femora and the tarsi fulvous, the pygidium with a central and a 

 lateral sinuate ridge, finely punctured. 



Hcib. India orient. 



Allied to C.fulvipes Baly, likewise from India, but larger, the 

 head pubescent, the sculpturing of the elytra quite different as well 

 as the colour of the legs. 



Chlamys stjmatkah^a, sp. n. 



Elongate, black, the head and thorax closely and finely reticulate- 

 rugose, the basal portion of the latter feebly raised, not divided, 

 more strongly transversely rugose ; elytra closely and deeply 

 foveolate-punctate, with a single distinct tubercle at the apex near 

 the suture, the latter finely crenulate ; pygidium finely rugose.
