GRAPE. LEAVES. 



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 flakes. I have also reared it . from pupaj 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 

 has left them, may everywhere be noticed adhering to the leaves. 



107. "Wounded leap hopper, Erythroneuravulnerata, 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 endj tips 

 smoky blackish. Length 0.12. Common in September. 



10§. Coquebert's Otiocerus, Otiocerus Chquebertii, Kirby. (Homoptera. 

 Fulgoridae.) 



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 w4th 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 tons as per- 

 taining to a genus peculiar to the United States, and very remark- 

 able for possessing long slender cylindrical appendages attached 

 to the base of their antennae, 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 up«»n and rigidly 

 api)ressed 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 

 (»f this country. Mr. Kirby long ago described eight species of 

 these singular insects from specimens found in Georgia by Mr.
