Genus Pygidicrana Serv. 



This genus is now restricted to the American forms. Zacher 

 figures the genital armature in P. V-nigrum Serv., the type of the 

 genus, and in P. fiebrigi Burr, which are the only two species so 

 far examined in this respect ; possibly some of the other species, 

 which are at present scarcely known, will require new genera. 

 I have shown the outlines of the metapararneres of the above- 

 mentioned species, from Zacher, for purpose of comparison (PI. V. 

 figs. 24 and 25). 



Genus Picrania Burr. 



This genus, with the following two, makes a natural group, 

 confined to the Ethiopian region, with a well-marked type of 

 genital armature. The long, narrow metapararneres, with lanceolate 

 tooth, are characteristic of Picrania, Dicrana, and Acnodes ; they 

 are only known in African species, and all known African species 

 have that type of armature. 



Picrania itself is only distinguished from Dicrana by the 

 narrow head, which is no broader than the pronotum. There is a 

 single undoubted species, P. liturata Stal, the type of the genus, 

 which unfortunately is only known from Stal's original nomotype 

 in the Stockholm Museum. Professor Sjostedt has been good 

 enough to send me an excellent water-colour of this specimen,
