290 Mr. W. F. Kirby on a 



Stenopilema pallicornis^ sp. n. 



Long. Corp. 13-14 millim., lat. 6 milllm. 



Female. — Black, thickly and finely punctured, more finely 

 on the hinder segments of" the abdomen. Head black ; an- 

 tenna?, antennal cavities, sides and lower part of face, legs, a 

 narrow line extending round the whole thorax and abdomen, 

 cerci, and more or less of the face and subterminal plate 

 below rufo- testaceous or reddish; rim of pronotum upcurved, 

 hinder angles produced backwards into a tooth ; meso- and 

 metanotum with the hinder angles slightly recurved. Eyes 

 rather wide apart. 



2, Pretoria [Distant). 



One of these specimens is labelled S. capucina, Gerst. ; but 

 capucina is a much larger species, with the head redder and 

 the antennas darker, besides other slight differences which 

 may be noticed in the description. There appear to be many 

 closely allied species of this genus. 



Cyrtotria scabra. 



Perisphceria scabra, Walk. Cat. Blatt. p. 172. n, 17 (18G8). 



1, Pretoria [Distant). 



Walker's type is said to come from South Africa, near the 

 l^ropic of Capricorn. 



Derocalymma (?) elateroides. 

 Perisphceria elateroides, Walk. Cat. Blatt. p. 176. n. 24 (1868). 



1, Barberton [Rendall) ; Natal [Gueinzius) (Nat. Hist. 

 Mus.). 



The hood of this species is interrupted in the middle, the 

 carinse being complete ; but 1 prefer to place doubtful forms 

 in Derocalymma till they are better known. The short stout 

 form of the insect resembles that of Pronaonota. 



Derocalymma versicolor. 



Derocalymnta versicolor, Burm. Handb. Eut. ii. p. 487. n. 9 (1838) ; 

 Bruim. Syst. Blatt. p. 317 (1865). 



1, Blantyre [Elson) ; 1, Delagoa Bay {Junod). 

 Two female specimens, which I refer to this species with 

 some doubt.
