XXIII. On the Homopterous genus Pyrops, with descrip- 
tions of two new species. By Witu1am L. Disrant, 
F.E.S. 
[Read November 8th, 1893. ] 
Tue genus Pyrops was founded by Spinola in 1839 (Ann. 
Soc. Ent. Fr., viii., p. 231), but the type must be sought 
in the description of his 2nd Division (p. 235), and in 
the P. tenebrosus, Fabr. To those who maintain that 
the first described or enumerated species of a genus is 
to be taken as the type of that genus, it would appear 
that a new generic name is required, for the first species 
cited is the Fulgora candelaria, Linn., which is un- 
doubtedly not a Pyrops in the sense universally used. 
However, all homopterists have followed Spinola’s second 
division as typical, and no useful end would be served in 
disturbing the arrangement. From this division, how- 
ever, must be eliminated the Fulgora obscurata, Fabr., 
from Australia, which Stal has placed in his genus 
Eurystheus (Hem. Fabr., ii., p. 115), and the Fulgora 
annularis, Oliv., from Central America, which belongs to 
the genus Diareusa, Walk. 
Pyrops is allied to Fulgora, and, like that genus, hag 
many points in common. Thus in both, though the 
specific characters are to be sought in the length and 
structure of the cephalic process, secondary characters 
to group the species are found in the colour of the 
wings, and in Pyrops in the colour of the abdomen. 
Fulgora is confined to the Oriental region, but Pyrops 
belongs not only to that, but also to the Ethiopian 
region, in the last of which are alone found the black- 
winged species ; whilst those with white wings are dis- 
tributed throughout the whole area of the genus. 
Having two undescribed species of this somewhat 
scarce genus in my collection, and possessing most of 
the other species, I have thought that a generic revision 
and enumeration might with advantage be given, and 
such I now present to the Society.
