Mr. M. J^m•\•— Notes on the Forficularia. .o87 



Genus IV. DiCRANA, nov. 



A geaere Pijgidicrana differt pronoto subrectangulari, sajpius sub- 

 quadrato ; a gonere Granopygia differt segmento penultirao 

 ventrali amplo, lato, rotundato. 



Type, Fygidicrana frontalis, Kirby. 



The rectangular pronotuiu readily separates the genus from 

 Pyg idler ana, but it only differs from Cranopijgia in the 

 broad, rounded, penultimate ventral segment. 



Tiie African species form a natural group witli a very 

 distinctive coloration. I have not examined an undoubted 

 P. coffra, but it appears to resemble P. bettoni and its allies 

 so closely that I do not hesitate to range it here. 



P. hallipyga has uiarked affinities with Cranopygia in the 

 form of the last dorsal segment and the forceps, but the 

 penultimate ventral segment of the male is so broad and 

 decidedly rounded that it is not possible to place it there ; 

 this is unfortunate, as its position near I). Jinschi appears 

 hardly natural.
