9. — Ora calcarafay n. sp. 



Oblong oval, depressed, shining, iBnely pubescent ; rufo-testaceous, the eyes 

 black ; closely, finely, the elytra much more distinctly, punctate. Head broad, 

 the eyes moderately large ; antennae very slender, joints 2 and 3 sliort, equal. 

 Prothorax convex, very broad, gradually, arcuately narrowed from the base, bi- 

 sinuate iu front. Elytra feebly rounded and narrowly margined at the sides, 

 rounded at the apex, with a shallow sutural groove. Posterior coxae without 

 plate. Posterior femora moderately dilated, the tibiae long and but little 

 widened, the u^^per spur strongly curved, quite slender, fully three times the 

 length of the lower one, and shorter than the first tarsal joint. 



Length 2|, breadth If mm. 



Hab. Amazons, between Pai-a and Santarem {S. M. Smith). 



One specimen, recognizable by the very slender, strongly curved, 

 upper posterior tibial spur, and the unusually broad head and prothomx. 

 An obscure, small, rufo-testaceous insect, with the general facies of a 

 Cuphon.

 10. — 07'« cassidiformis, n. sp. 



Subhemispheric, depressed, explanate laterally, shining, pubescent ; testa- 

 ceous, the prothorax with some indistinct markings on the disc, and the 

 elytra with a faint, interrupted, angulate fascia below the base and a trans- 

 verse patch near the suture at about the middle, fuscous or piceous, the suture 

 itself flavescent ; closely, finely, the elytra more coarsely and subrugosely, 

 punctate. Plead small, hollowed on each side between the eyes ; antennae 

 long, slender, joints 2 and 3 short, equal, 4-11 elongate. Prothorax very short, 

 rapidly narrowed from the base, deeply sinuate in front opposite the eyes, the 

 disc obliquely depressed on each side anteriorly. Elytra with broadly ex- 

 planate flattened margins, without grooves or costae on the disc. Posterior 

 coxae without plate. Posterior legs very long, the tibiae widened, curved, 

 compressed, sharply carinate, the upper spur elongate, curved at the tip, shorter 

 than the first tarsal joint. 



Length 4-4i, breadth 3-3i mm. 



Sah. Cameeoox Mts. (C Christy); UGAiVDA, N.W. shores of 

 Victoria Nyanza, alt. 3800-3900 ft. ( S. A. Neave: ix.l911). 



Two imperfect examples, the Cameroon one taken as the type. The 

 Uganda specimen is a little narrower, and wants the faint darker markings 

 on the elytra, which may be partty due to discoloration in the type, the 

 suture in both remaining flavescent. The subhemispherical shape, broadly 

 explanate elytral margins, and dilute coloration give this insect the facies 

 of a Paropsis (an Australian genus of Phytophaga), Cassida, or Coc- 

 cinella. Scirtes ex2:)lanatus Pic (1913), from Dahomey, and S. cassidi- 

 oides Bourg. (1890), from Cochin China, are probably allied forms, and
