together, but the marks upon the thorax are totally different from 
those of that species. I have sometimes met with this leaf hopper 
in such numbers upon the grape vine, in September, that when 
the leaves were agitated, the insects taking wing resembled a 
shower of snow r flakes. I have also reared it from pupae found, 
upon the leaves sucking their juices. The young begin to appear 
a month or two earlier than the perfect insects, and resemble 
them, but are smaller and destitute of wings. And their cast 
skins, delicate, milk white, retaining the form of the insect that 
lias left them, may everywhere be noticed adhering to the leaves. 
107* Wounded leap hopper, JErythroneura viUnerata y Fitch. 
Tawny yellowish, sometimes tinged with red, the wing covers 
with white dots and veins and on the middle of the outer margin 
an oblique black streak between two cream white spots, the hind 
one smaller and with an oblique blood red line at its end; tips 
smoky blackish. Length 0.12. Common in September. 
108. Coquebert’s Otioceuus, Otiocerus Coqucbertii, Kirby. (Homoptera. 
Fulgoridai.) 
A slim four-winged fly of a yellowish white color with a bright 
carmine red stripe along each side of the body and wings, which 
stripe is widely forked at its hind end. Length 0.42. I have 
met with these delicate pretty flies from the middle of July to the 
end of the season, more frequently upon the wild grape vine than 
on any other plant or tree, but they are never so numerous as to 
do any perceptible injury, and are chiefly interesting to us as per¬ 
taining to a genus peculiar to the United States, and very remark¬ 
able lor possessing long slender cylindrical appendages attached 
to the base of their antenna;, nothing analogous to which are 
found in any other insects. These appendages vary in their 
length and form in different species. They resemble a slender 
tapering worm, irregularly crooked, lying upon and rigidly 
oppressed to the cheeks of the insect’s face and sometimes passing 
over the eye- The use of these curious appendages will form an 
interesting subject for the investigation of some future naturalist 
this country. Mr. Kirby long ago described eight species of 
these singular insects from specimens found in Georgia by Mr.
