164 ON NEW PHYTOPHAGOUS COIiBOPTEEA. [Feb. 19, 



Of rather elongate, medially constricted shape, the head entirely 

 and closely rugose, the anterior portion obscure fulvous, the rest 

 black ; eyes deeply and elongately notched ; antennae obscure dark 

 fulvous ; thorax with the posterior portion gradually raised into 

 a round elevation, the latter not sulcate but more strongly 

 reticulate-rugose than the rest of the surface and of a deeper black 

 colour, the sides and the anterior margin very obsoletely stained 

 with fulvous ; scutellum impunctate, strongly transverse ; elytra 

 very closely and deeply punctured, with a very obsolete ridge from 

 the middle of the base to the apex, where it ends near the suture 

 in a tubercle of moderate size, there are traces of other ridges also 

 at the sides but they are very indistinct, and the whole surface 

 presents more the appearance of reticulations in different directions ; 

 pygidium of oval shape, the margins acutely raised, the surface 

 rugose ; entire under surface and the legs finely rugose, of more 

 piceous or paler colour than above. 



Hah. West Central Sumatra. 



From the Malayan region only two or three species of Ohlamys 

 are known, which quite differ in sculpturing from the present 

 insect, described from a single example in my collection. 



Besides the species already mentioned, I have added to the 

 drawings accompanying this paper figures (Plate XIV. figs. 10- 

 12) of three other well-marked species of Chlamys from Brazil. 

 These are : — 



C. hirta Kollar, Mon. Chlam. p. 7. 



C. luteolaGcevm. Ins. Spec. nov. p. 654. 



C. smaragdina, Klug, Entom. Monogr. p. 154. 



These and most of the other species have also been well described 

 in Lacordaire's Monograph of the Phytophagous Coleoptera 

 (vol. ii. p. 649).
