254 Mr. Warren on the Pyralidina collected 



PTEROPRISTIDiE. 

 I propose this family to include all the species in 

 which the hind margin of the fore wing is fissured, that 

 is to say, the three genera, Tortricodes, Gn., Gaberasa, 

 Wlk., and Pteroprista, n, g.

One 3' , from Teffe, Oct. 18th, 1874. 



As Guenee's single 3 was in such bad condition that 

 he was unable to give an exact description of it, I here 

 append one, as well as a more detailed account of the 

 structure and neuration of the genus (as derived from 

 this species), which latter seems to me not quite cor- 

 rectly given by Guenee : — 



Fore wing with costa straight for one-third, then excavated for 

 another third, the cavity being filled up with a fringe of hairs, 

 which projects a little beyond the costal outline ; apical third 

 strongly convex, almost elbowed, appearing, as Guenee expresses 

 it, as if cut off with a pair of scissors ; hind margin for one-thhd 

 vertical, or even almost sloping outwards, then carved out, with a 

 deep incision running inwards quite one-third towards the base, 

 and curved upwards at its end, thus forming two lobes ; the edges 

 of the incision with fringes like the rest of the hind margin. 

 Under side : Costa with a strong fold from the base fringed with 

 long hairs, which extend also along the edge of the central con- 

 cavity ; the median vein is fringed with long hairs, which termi- 

 nate in a raised funnel-shaped tuft before the upcurved end of the 

 incision ; hind wing rounded. Neuration : Fore wing with the 

 costal nervure hidden under the fold, and forming beyond it the 

 margin of the costal concavity; first subcostal branch starting 

 half-way down the cell, just beneath the beginning of the costal 

 cavity ; second half-way between the first and the end of the cell ; 

 third, fourth, and fifth from a common stem just before the end ; 

 the fifth leaving very near the base of the stem ; the fourth half- 

 way towards the apex. Submedian running straight to the anal 

 angle ; interno-median fold strongly developed ; first median branch 

 at one-third before the end of the cell, strongly curved at its origin, 

 and running into the top of the lower lobe ; second just before the 

 end, apparently running round the end of the incision, and termi- 

 nating shortly on the inner margin of the front lobe ; third median
