FURTHER NOTES ON SINHALESE RHYNCHOTA. 39 



, suture strongly marked, neuration of corium very much as in 

 ^ (^ Gypona glaiica (Fabr.), but there is no membrane. The second 

 apical area of the wings is quadrangular. Posterior femora 

 apically bispinose, tibiae externally with five strong short spines, 

 tarsi short and stout. There is a somewhat elevated transverse 

 carina extending across the sterna, separating the anterior and 

 posterior lobes of the intermed^te coxse. Counexivum ventral, 

 subvertical, strongly developeoT' Type, E. kirhyi, Kirkaldy, 



This genus is distinguished from its American ally l3y the 

 form of the head and of the antennae.

In the female the 6th abdominal segment is conyexly rounded 

 apically, and not excavated as in nK)st species of Gypona. The 

 head is shorter and squarer thanitraJ. ivalkeri, being 5-angulate, 

 while m'ivalkeri it is triangulate.

In the female the 6th abdominal segment is straight apically, 

 the 7th being enormously long in proportion to the others. 



Fam. -^ULGORiD^. 

 ^ EoDELPHAX, gen. nov.* 

 Belongs to subf. Asiracinse (Delphacinae of authors). Vertex 

 nearly square, depressed inwardly, the lateral margins forming a 

 sharp carina extending alongside the inner margin of the eyes as 

 far as the intero-posterior angle of the latter, which extends 

 posteriorly almost as far as to the base of the pronotum. These 

 carinse are continued forward to the apex of the head, forming a 

 right angle there; the part of the vertex anterior to these carinas 

 is depressed inwards, declivous, and rounded marginally. Vertex 

 feebly carinate medianly longitudinally. Frons long-oval, trun- 

 cate at each end, carinate (with clypeus) medianly ; clypeus 

 long, triangular. Antennae prominent, very large, first segment 

 compressed and dilated, obliquely triangular, the interior side 

 longer than the exterior ; second segment slightly longer than 

 the first, compressed, very tuberculate. Eyes latero-ventrally 

 deeply grooved medianly to admit the cariniform first segment of 

 the antennae during repose. Eostrum reaching to posterior coxae. 

 Pronotum slightly narrower apically than the base of the head, 



■'- ^^Eos" in this combination and in "Eogypona" has reference to 

 " dawn " as appUed to the Oriental Eegion, not as siipposing an ancestral 

 form, as in Eohippus, &c.
