Genus Eupteetx, Curt. 
\.—Eupteryx albostrielhcs, Fall. 
Mavus vel albidus ; pronotum vittis 2, hemelytra vittis 3 lougi- 
tudinalibus aureo-citriuis. Alarum nervi longitudiuales 4, quartus 
abbreviatus. Abdomen flavum, vel nigrum incisuris flavis. Pedes 
flavi. (J $ . Long. 1| ; alar. exp. 4 lin. 
Cicada allostriella, Fall., Hem., Pt. 2, p. 54. 
TijiMocyba id., Flor, E. L., 2, p. 382. 
Cicadula elegantula, Zett., Ins. Lapp., p. 298. 
Var. a. — Unicoi orous, without orange-coloured stripes, apex of the 
cerium, and the membrane, fuscescent : T. fulveola, H. Sch., D. Ins., 
164, 16. $ . 
Var. h. — Similar, but of a much deeper yellow ; the wings also 
dusky. In one instance the hemelytra are entirely clouded with dusky, 
except at the base. 
Var. c. — Pronotum and scutellum broadly brown ; hemelytra

Curt., B. E., 640, No. 3 (not of Brit. Mus. Coll., which is E. parvulus. 
Boh.).— I^. vitrea. Walk., Cat. of Homopt., 42. 
I believe also at present that T. rubi and T. exiniia, Hardy, Tynes. 
Trans., 1, 417, belong to this species, although the latter is represented 
in the Brit. Mus. by the roseate variety of E. citrinellus, Zett. 
Very common on oaks, elms, and other trees, throughout the 
country. 
2. — Eupteryx citrinellus, Zett. 
Sulphureus ; hemelytra hyalina, clavo coriique margine externo 
late citrinis vel flavis : sed ha^c pictura interdum obsolescit. Vertex 
Deltocepliali, triente brevior quam pronotum. Abdomen nigrum, basi 
et apice flavum, $ ; vel tantum dorso medio nigrum, $ . Pedes flavi. 
Long. 1-1^^ ; alar. exp. 3 lin.
