Sp. 1. Cato. carinatus. Obscure ferruginea : prothorax crebre 

 punctatus : singuli elytri stria duce, interstitiis punctis et quadri- 

 lineatis. (Corp. long. "45 unc. lat. '075 unc.) 



Entirely of a dusky ferruginous or pitchy red, not very 

 shining. The form is depressed, linear, and very narrow. The 

 antennae are of nearly uniform substance, each joint externally 

 incrassated; the terminal joint is slightly longer but not thicker 

 than the rest. The head has a deep transverse furrow near 

 its posterior margin ; at each extremity this is joined by a la- 

 teral marginal furrow, which originates near the insertion of 

 the mandible, and passes above the antenna and eye : in front 

 of the transverse furrow, but quite unconnected with it, are 

 two deep elongate impressions, and between these is a very 

 slightly marked line, which proceeds from the middle of the 

 transverse furrow to the clypeus, where it terminates in a cir- 

 cular impression. The prothorax has a very slender posterior 

 and lateral marginal ridge. Each elytron has two furrows ; 

 the first originating on one side of the scutellum and termi- 

 nating in the apical angle, the second originating dorsally near 

 the shoulder and terminating considerably before the apical 

 angle ; the interstice between these furrows has four distinct 

 lines, which become obliterated before the apex. The head, 

 prothorax, and elytra are thickly punctured, the punctures on 

 the elytra requiring a lens of high power. 



Inhabits the Cape of Good Hope. I am indebted to the Rev. F. 

 W. Hope for the loan of one specimen, and to Mr. Westwood for 

 that of another. The name of carinata, Klug, has long been attached 

 to this species, but I am not aware of a previous description. Spe- 

 cifically this is distinct from the following, but I can discover no cha- 

 racters of distinction of higher importance than those of sculpture, 

 which so obviously mark the species throughout the family. 



Sp. 2. Cato. castaneus. (Corp. long. 55 unc. lat. "125 unc.) 

 Isonotus castaneus, Perty, 'Animal. Artie, of Brazil.' 

 p. 114. tab. xxii. fig. 15. 

 Ferruginous, shining. Form less elongate than in C. cari- 

 natus, body scarcely so flat, and antennae not so long in pro- 

 portion to the body; the sculpture of the head exactly as in 

 that species. Prothorax very shining, but under a lens of 

 moderate power very obviously punctured ; the disk is very flat
