The largest of the genus, and distinct from all other species by the 

 shape of the vertex. Face very long, with three parallel carinse, of 

 which the medial is the broadest, and is forked upon the vertex. Eyes 

 reddish. The black apical stripe of the hemelytra is often absent, 

 sometimes doubled, and continued to the base ; in the variety described 

 by Curtis (see his fig.) it occupies nearly the entire surface. The black 

 marks on the abdomen are similarly inconstant. The spurs of the hin- 

 der tai'si, and the last joint of all the tarsi, tipped with black. 



Common on the south coast, and near London (Wimbledon, Esher, 

 Epping) ; also on the Cotswold Hills, Cheltenham, and Swithland Slate 

 Quarries, Leicester. 



B. — Vertex transversus ; ultra oculos non, aut vix, porrectus. 



* Hemelytra apice quam basi angustiora, abdomine semper longiora. 

 t GensB nigro unimaculatae ; hemelytra apice nigrolineata. 

 2. — Delpliax guttula, Germ. 

 Albido-ochraceus, pronoti scutellique lateribus, et abdomine supra 

 plus minus nigricantibus. Genarum apex utrinque macula magna 

 nigra rotunda notatus. Hemelytra abdomine longiora, linea apicis lon- 

 gitudinali, extrorsum latiore, nigrofusca. i^ $ . 



Long, l-li, alar. exp. 21-31 lin.

 (Fulgora minuta. Fab. is more likely to be this than the pre- 

 ceding, but his brief description is vaguely applicable to both.) 

 The dark stripe on the hemelytra is sometimes visible to the base, 

 where it is narrower and paler. Sometimes it appears only as a black 

 triangular spot at the apex, in which case the hemelytra are shorter and 

 blunter. The wings are sometimes rudimentary, and then the hemelytra 

 are much narrowed at the apex, but never shorter than the abdomen. 



* This species recedes so much from the type of Delpluix, that, in a monograph, I should scarcely 

 hesitate to eatablisli a now genus lor its reception. Its claims to separation are at least cr|iml to that 

 of Araopui and Asiraca. The structure of its head indicates a relation to Pseudophana, of which one 

 species is found in southern Rurojie.
