Frons longitudinally convex, gense anteriorly rotundate, neither 

 (frons nor gense) produced in the middle. Ocelli distinct. Antennse ; 

 segments of the peduncle elongate, first extending considerably beyond 

 the lateral margins of the gense, second about one-fifth longer than 

 the first. Tegmina very greatly decumbent, very ample, sensibly 

 widened towards the apex, rotundate, with a single regular series of 

 transverse uervures towards the apex ; corium, etc. (except at the base) 

 with numerous transverse nervures ; many of the longitudinal nervures 

 furcate. Costal membrane dilated, basally narrowed more than twice 

 as long in the middle as the costal area. Posterior tibise with one 

 spine. Abdomen compressed. 



I have great pleasure in dedicating this genus to my friend, Dr. H. 

 J. Hansen, to whom liomopterists are indebted for the essay upon the 

 more minute structure of the auchen norrhyncha. It is allied to 

 Cerynia^ Stal, but differs abundantly in the neuration, etc. It is 

 superficially exceedingly like Copsyma, Stal, as represented by C. 

 tineoides (Oliv.) [= C. stollii (tSpin.)], but in the latter the neuration of 

 the tegmina is quite different, there being no regular row of transverse 

 nervures near the apex, while the head is much wider and the first 

 segment of the peduncle very short. C. tineoides is at once distinguish- 

 able (beyond the structural characters) by the curved whitish streak 

 and the whitish specks on the tegmina. The only species of Hansenia 

 known to me is

Apparently confined to Ceylon, " It sometimes covers the leaves of 

 certain Eugenia trees upon which the larva feeds, and when disturbed 

 flies out in clouds." {E. E. G., Dec. 13, '99.)

I had commenced the figuring of the details of neuration, etc., of several Sinhalese 

 Poekillopterinae, but as I find, since this paper was in proof, that my friend Dr, Melichar 

 of Vienna is monographing the group, these details have been omitted here.
