Tlie Cenirutyjjiis alatus, Yinvm., is well figured, but the 

 locality given (Brazil) is evidently incorrect. Tiie British 

 jNIuseuni possesses a typical example. The Centrotyims 

 alatus^ Buckt., was described from a specimen in my own 

 collection and now contained in the British Museum. This, 

 therefore, required a new name.

Hub. Borneo ; Sarawak {J. E. A. Lewis). 



The British Museum now possesses a single (somewhat 

 damaged) specimen of this very rare Membracid, the original 

 type of which has been recently minutely and excellently 

 redescribed by Dr. Aehille Griffini. 



Lestarches, gen. nov. 



Allied to Centi'otypus, Stal, but differing principally by the 

 structure of the posterior pronotal process, which is broad, 

 very distinctly cariuate, distinctly moderately convex beyond 

 scutellum, its apex subacute and distinctly deflected, over the 

 posterior angle of the inner tegminal margin; disk and 

 front of pronotum strongly centrally longitudinally carinate.
