three genera (omitting the Issidao) which were correctly used 
except that he included L. Jf-angularis under Aplirophora; in his 
recognition of species he was less fortunate, as all three of his 
species of Pliiloenus were varieties of spumarius. 
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 five; aside from that, however, the only 
excuse for inserting the fifth genus (RMnaulax) was a MS. 
note by Dr. Fitch, placing the fabrician species coccinea there, 
while A. & Serv., the authors of all five genera, placed it in 
the first {Tomaspis). Under the Aplirophorince he separated six 
genera, although of one (Glovia) he made no reference in the 
catalogue, and of another {Ptyelus), he left only two undeter- 
mined species of Walker’s, one of which was a Philcenus, 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. fasciaticollis StB>l=simulans Walk, and Mcincta Ssbj=rubra 
Linn. The first appears to be correct; the second is not, as 
can be readily seen by comparing bicincta with his figures, 
when it will be seen that it equals simulans and not rubra, and, 
being the first described, takes precedence. He also described a 
number of new species of Clastoptera without recognizing 
xanthocephala, proteus or delicata, 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 Clastoptera, 
which, with the present paper, completes the family. While 
working on that paper P. lineatus and bilineatus were recognized 
as distinct and attention was called to the generic difference, 
the venation of each species being figured on the generic 
plate.
