PLBUKOXEUROPHTOX. ALLOCA MPTUS. 373 



basally ; basal nervure not continuous through median ; nervellus 

 intercepted far below its centre. 



Range. Hawaii, Ceylon. 



This genus was founded upon a MS. species from Hawaii ; 

 the following is the only one ever published as appertaining to it, 

 and even here certain discrepancies lend some doubt as to whether 

 it really belongs to the genus. 



Respecting 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 

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

 genus and of Enicospilus, but it wants the horny points found 

 always in the latter genus."

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

 Antennas subrufescent. Thorax pale testaceous, with the meso- 

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

 the proplenrae obscurely striate ; metanotum with broadly rounded 

 stria3, except at its glabrous base, where the impression bears two 

 stout and several indistinct striae ; metapleural carina3 broad, 

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

 Aldomen, except basally, rufescent- testaceous, becoming darker 

 apically. Legs testaceous, with the anterior pairs paler. Wings 

 hyaline, with the stigma testaceous arid the nervures blackish; 

 disco-cubital nervure centrally thickened and elongately fenestrate, 

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

 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 not continuous through median ; 

 nervellus intercepted far below its centre. 



Length 14-15 tnillim. 



CEYLON : Peradeniya (E. E. Green). 



Unknown to me.

GENOTYPE, Ophion undulatus, Grav. 



This genus is closely allied to Henicospilus and has the base of 

 the radial nervure similarly thickened, but the very obvious 

 glabrous alar area is destitute of corneous marks, with the result 

 that it has but quite recently been accorded generic rank apart
