19. — Eupteryx jucundus, H. Sell. ? 
Pallide viridi-flavus ; vertex, pronotum, scutellum, nigro raaculata 
(maculse verticis 2, pronoti 5), hemelytra longitrorsum fusco vittata. 
Pectus et abdomen nigra ; hujus incisurse auguste flava?. Pedes pallidi, 
unguibus fuscis ; coxae postiese subtus macula nigra. 
The vertex is yellowish-wliite, with two large round spots at the 
apex, between the eyes ; hinder margin very narrowly bordered with 
black, and with a small central black spot, anteriorly acuminated. 
Pronotum with two anterior black spots, and three more arranged 
transversely on the disc, the middle one narrowed behind, and broader 
in front than the two lateral spots. Scutellum with two triangular 
black spots at the basal angles, and a black spot in the transverse 
depression before the apex, from which a narrow black medial line 
extends to the base. Hemelytra with five longitudinal brown stripes 
(two on the clavus, three on the corium) ; the nervures greenish-yellow • 
Of the three longitudinal alary veins the two anterior, or outer, are 
blackish, the inner one finer and pale. Long. 2 lin. 
Typhi, jucunda, Flor, E. L., 2, p. 632. 
Mr. Douglas has a specimen which appears to belong to this species. 
Being unprovided with a type at the present moment, I am compelled 
to translate and abridge the description of Flor. He states that the 
insect is found on the common alder. Probably the specimen labelled 
T.fulva, H. Sch., in the British Mus., is identical with the above. 
20. — Ewpteryx quercus, Lin. 
Albidus ; vertex ssepe linea sinuata antica citrina : pronoti margo 
anticus, macuL-eque 3 ejusdem discales,— scutelli omnes anguli — heme- 
lytrorum maculge 5-7 irregulares, oblongae, plus minus confluentes, 
citrinfe vel rubrse. Corii cellulse apicales 2 magnse prope costam, fusco 
cinctse, ocellataj. Membrana cellulis (praesertim basalibus) infuscatis, 
nervis albidis. Pedes albidi, tibi® postiese apice ipso fusco : unguiculae 
fuseesceutes. ($ ? . Long, li; alar exp. 3 lin. 
Cicada quercus, Tab., S. R., 79, 89. 
T. quercus, Plor, R. L., 2, p. 412. 
T. fasciata, ToUin, ueber Kleinzirpen, in Stett. Eut. Zeit., 
1851, p. 73. 
Abundant on various trees, but especially oaks, throughout northern 
Europe. In the British Mus. T. gracilis, Zett. ? is mixed with the 
present species.
