three genera (omitting the Issidae) which were correctly used 

 except that he included^!/. 4-angularis under Aphrophora: in his 

 recognition of species he was less fortunate, as all three of his 

 species ofTMlcenus were varieties ofspumarius. 



In 1892 Dr. Goding published a synopsis of the genera, 

 together with a bibliographical and synonymical catalogue of 

 the described species; the characterization of the family was 

 simply a translation of Stal's in Hemip. Africana, and the 

 synopsis of the subfamilies and genera an adaptation from the 

 same work. Under the subfamily Cercopince, he recognized five 

 genera, although Stal himself, the next year after the publica- 

 tion of that synopsis, united four of these genera, and later 

 (Hemip. Mex.), all live; aside from that, however, the only 

 excuse for inserting the fifth genus' (BJiinaulax) was a MS. 

 note by Dr. Fitch, placing the fabrician species^ coccmea there, 

 while A. & Serv., the authors of all five genera, placed it in 

 the ^vsi' {Toniaspis). Under the^AphropJiorince he separated six 

 genera, although of one [Glovia) he made no reference in the 

 catalogue, and of SinoiheiP (Ptyelus), he left only two undeter- 

 mined species of Walker's, one of which was sPpjiilcenus, and 

 the other a^Lepyronia, while the genus Ptyelus, as characterized 

 by him (from Stal), has not been recognized outside of Africa. 



Fowler, in the Biologia, describes a number of new genera 

 and species of Cercopidse, and has worked out considerable 

 synonomy, of which only the following affects our species: 

 ^ T. fasciaticoUis St3b\=simulans Walk, and Mcincta Saj=^rubra 

 Linn. The first appears to be correct; the second is not, as 

 can be readily seen by comparing' Mcincta with his figures, 

 when it will be seen that it equals .si//m/arj.s and not "rubra, and, 

 beifig the first described, take^precedence. He also described a 

 number of new species of Clastoptera without recognizing 

 xanthocephala,^proteus or^cklicata, specimens of all of which have 

 been examined from Orizaba and other Mexican points, includ- 

 ing several varieties, so that no doubt most of his species will 

 fall as synonyms. ^ 



In 1896 the author published a revision of the^Cflastoptera, 

 which, with the present paper, completes the family. While 

 working on that paperV. lineatus Sknd'^ilineatus were recognized 

 as distinct and attention was called to the generic difference, 

 the venation of each species being figured on the generic 

 plate.
