ON CERTAIN BRITISH HEMIPTERA-HOMOPTERA. 
(Revision of, and additions to, the Aphrophoride and Ulopide). 
BY JOHN scorT. 
(Continued from page 196). 
Some few families of the Homoptera are but poorly represented in this 
country ; so poorly indeed, that it is not uncommon to find a family 
represented by a single genus, and that genus by but one species ; 
whilst the chances of increasing their numbers are, in most instances, 
hopeless. As examples, take the Jssid@ and the Cercopide: the former 
only boasts of the well-known Jssus coleoptratus, Fab., and the latter 
of the equally well-known Cercopis vulnerata, Illig. (sanguinolenta, 
Panz., nec Lin.). Both of these insects appear to belong exclusively to 
the south, as I have hitherto not seen either of them, nor am J aware of 
their having occurred, in Scotland or the northern or midland counties of 
England. Of Ireland, as usual, I can say nothing ; nor will much be ~ 
learned until she has a Birchall in Bugs, as she has in Butterflies. 
Why vulnerata has not been noticed in Scotland seems strange to me, 
as its wide distribution certainly leads to the conclusion that it ought 
to be found there. Of the Zettigometride, we did not possess a single 
species until the year 1866, when the sharp eye of the Rev. T. AS 
Marshall led him to detect one amongst his captures in Pembrokeshire. 
The same species had also been taken in the Isle of Wight by Mr. J.C. 
Dale, and was subsequently recognized by Mr. Douglas amongst that 
gentleman’s stores. I refer to the Tettigometra impressopunctata, 
L. Duf., a species unknown to Fieber, who in the Verhandl. d. k. k. 
zool. bot. Gesell., 567, 14 (1865), describes it under the name frontalis. 
The insects of this genus are very similar in appearance to Acocephalus, 
and perhaps still more resemble Péyelus ; but the shape of the anterior 
margin of the pronotum and the hinder tibiee (without spines) will lead 
any one at a glance to discover whether they are mixed up in collec- 
tions with either of these genera. On the continent, some 30 species 
are known, and it is just within the range of probability that we may 
add 7. atra, Hagenbach (taken by Flor), 7. Jeta, H. Sch., and | 
obliqua, Panz. (said by Fieber to occur in Germany); the others are 
all from places too far south to permit us to hope of their being, 
correctly enumerated as British. | 
The above, I believe, are all the families interposing between the 
Civiide, which I have already dealt with, and the Aphrophoride ; and! 
I have not thought it necessary in this paper to do more than point 
to them in passing, as they have been already sufficiently described in 
this country.
