6 COLEOPTERA CHLAMYDAE. 



Clilamys truncatus nov. sp. Elongate, opaque, head dark, 

 thorax coppery bronze, elytra opaque brownish-black tinged with 

 purple, end of the body squarely truncate, the truncation of the elytra 

 bronzed, abdomen brown opaque, body beneath of the latter color ; 

 antennae, except the end, labrum and tarsi, fulvous ; presternum with 

 sides parallel at its front, then gradually narrowed to middle, the rear 

 half a parallel edge , length 3.5 mm. 



Type. — 9 ; Cochabamba, Bolivia, two 9 specimens. 



Head thickly and rugosely punctate, antennae with second 

 joint obconic, third stout and trigonate, remainder transverse, 

 the last four or five joints dark, thorax with rather coarse 

 punctures, not thick, hump large, declivous and well defined 

 at the base, rather deeply divided by the median sulcus, 

 which has a deep pit at the apex of the hump, and then is con- 

 tinued broadly to nearly the anterior margin. Each side of 

 the middle is divided by two irregular transverse ridges 

 which pass down to the sides. There are two lateral tuber- 

 cles, and the rear edge is prolonged and sharply notched 

 behind. The elytra have the usual sutural and median lines, 

 the others being broken. The entire surface is reticulate, 

 becoming coarser at the apex. The edge of the truncation 

 is marked on each side by two sharp, prominent tubercles, 

 one sutural and the other median; suture finely dentate, 

 pygidium punctate, obsoletely tricarinate, body beneath 

 coarsely reticulate. 



The peculiar coloration and truncate elytra will distinguish 

 this form ; belongs in Lacordaire's Group 7. 



Chlamys carinipennis nov. sp. Elongate, shining brown, 

 body below, black, hump of the thorax darkened, its anterior apex 

 deeply bilobed and elevated into two sharp fan-shaped carinae ; 

 elytra with the usual lines more or less abnormally elevated into sharp 

 carinae, apex abruptly truncate, suture smooth or nearly so, pros- 

 ternum strongly margined with sides at first parallel, then abruptly 

 narrowed to a trifle beyond the middle, then gradually enlarged again 

 to an obtuse end, thus presenting a definite constriction at the middle ; 

 length 3j mm. 



Type. — One cf ; Cochabamba, Bolivia. 



Head thickly punctate, the vertex with two small tubercles, 

 somewhat like occipitalis Lac, only not so prominent, an- 

 tennae with 2d joint stout, obconic, 3d stout, trigonate, re-
