Captain G. E. Shelley has several specimens of it from Bamangwato 



and the Umvuli River. 1 ., ~. , /-wr-/r 



A. Sidney Olliff. 



#** Mr. Olliff had determined this insect as a distinct species previous to his departure for 

 Australia, and the above description was already in type when Mr. Fowler's article appeared 

 in the 'Transactions of the Entomological Society,' with his description of L. Nyassce. Mr. 

 Olliff having written to call attention to the fact, the specimen in the Oxford Museum described 

 by him has been kindly compared by Mr. H. W. Bates with the type specimen of L. Nyassa, 

 in the possession of the Rev. H. S. Gorham, with the result that Mr. Bates has come to the 

 conclusion that the two specimens belong to the same species. The name Mr. Olliff had given 

 the species has therefore, with his authority, here been cancelled, whilst it has seemed advis- 

 able to retain in full his description of the insect together with the accompanying figure of it 

 in Plate VIII.— Ed.

1 Captain Shelley also possesses a closely allied species collected by the late Mr. J. S. 

 Jameson at Bamangwato, which may be briefly characterized as follows : — 



*Languria atricolor, Olliff, n. sp. 



Elongate, depressed, black with a slight purplish tinge, shining; head moderately 

 strongly punctured ; the eyes not very prominent ; antennae black, with a loosely articulated 

 club of three joints ; prothorax rather convex, transverse, very slightly narrowed behind, 

 moderately strongly and closely punctured ; sides feebly arcuate, with a fine marginal rim ; 

 elytra moderately strongly and closely punctate-striate, except near the scutellum, where the 

 punctures are irregular and obliterated as in L. Nyassa ; under side and legs coloured as 

 above, the former moderately strongly punctured throughout. Length, 10 mm. 



From Bamangwato (Jameson). 



Differs from Languria. Nyassa in its broader form and black colour, and in having the 

 prothorax transverse with the sides arcuate and the elytra more strongly punctate-striate.
