CHARACTEES OF TWO NEW GENERA OF FTER0PR0RID2E FROM 

 SPECIMENS IN THE BRITISH MUSEUM. 



BY LORD WALSINGHAM, M.A., F.L.S., &c. 



Heptaloba, gen. nov. 



Palpi capite longiores ; alee anticcB ultra medium fissce ; lacinicB 

 singulce, antica ad medium postica ultra medium, etiam jissce ; cilia digi- 

 ticuli costalis ad apicem acuminata, aliorum suh-ahrupte dejlexa ; alee 

 posticcG trilohatce, fissured, antica vix ultra medium, postica prope hasim^ 

 projectce ; digiium tertium denticulatwn ; tihice posticce cristatce, calcari- 

 hus prelongis ; abdominis margines sub-ciliatcs. 



Palpi longer than the head, the third joint, more than half as long as the 

 second. 



Fore -wings cleft beyond 

 their middle ; the anterior and 

 posterior lobes being also cleft, 

 the one to half, the other to more 

 than half its length ; the fringes 

 of the anterior or costal division 

 of the upper lobe running to a 

 point at the apex, those of the 

 other three divisions ending 

 more abruptly. 



Hind-wings with three 

 lobes ; the upper cleft extending 

 very slightly beyond the middle, 

 the lower cleft reaching nearly 

 to the base. The posterior lobe 

 toothed with projecting tufts of 

 scales on the abdominal margin. 



Abdomen somewhat fringed 

 at the sides on the posterior 

 edges of the segments, much or- 

 namented with triangular pale 

 markings above. 



Legs with very long slender 

 spurs, tufted above at the base 

 of each pair. The first pair of 

 spurs on the hind legs are equal 

 to each other in length. 



This Ceylonese genus is distinguished at first sight by the pre- 

 sence of four lobes in the fore-wings, instead of two only, as is usual 

 in the Fterophoridce ; Deuterocopus, Zell., which has three, being the 

 only other known exception. It appears to be allied to A^nhlyptilia, 

 Hiib., having the first pair of spurs on the hind legs equal to each
