 iiitpi'cepted far below its centre. 



Range. Hawaii, Ceylon. 



'JMiis genus was founded upon a lAKS. speciL'S from Hawaii ; 

 the following is the only one ever ])ublished as appertaining to it, 

 and even liere certain discrepancies lend some doubt as to whether 

 it really belongs to the genus. 



Kespecting the Indian species, Cameron says (Spol. Zeyl. 1905, 

 p. 121): — "Except that there can hardly be said to be a stump 

 of a nervure on' the disco-cubital nervure, this species fits into 

 Pkaroneurophion . It has the thickened base of the radius of that 

 genus and of Enicosjnlus, but it wants the liorny points found 

 always in the latter genus."

2 . Head pale ilavous, with the ocellar region not black. 

 Antoiuo; subrufescent. Tlwru.c pale testaceous, with the meso- 

 notum subrufescent; pro- and meso-thorax closely punctate, with 

 the propleurae obscurely striate ; metauotum with broadly rounded 

 stritTB, except at its glal)rous base, where tlie impression bears two 

 stout and several indistinct stria); mefapleural carina? broad, 

 slightly reilexed centrally, and rounded at both base and apex. 

 Abdomen, except basally, rufescent-testaceous, becoming darker 

 apically. Ler/s testaceous, with the anterior pairs paler. Wings 

 hyaline, w itli the stigma testaceous and the nervures blackish ; 

 disco-cubital nervure centrally thickened and elongately fenestrate, 

 its basal abscissa slightly rounded downwards at the apex, and tlie 

 apical abscissa slightly but distinctly longer than the basal abscissa 

 of the cubital, which is a little shorter than the recurrent nervure ; 

 nervelet subobsolete ; radial nervure basally thickened ; glabrous 

 area wanting; basal nervure )iot continuous through median; 

 nervellus intercepted far below its centre. 



Lenr/th 14-15 millim.

Genotype, Ophion undulatus, Grav. 



This genus is closely allied to IJenicoi^pilus and has the base of 

 the radial nervure similarly thickened, but the very obvious 

 glabrous alar area is destitute ol' corneous marks, with the result 

 that it has but quite recently been accorded generic rank apart
