94 European Butterflies and Moths. 



GENUS II.— NACLIA (BOISD.). 



Hind margin of the fore-wings as long as the inner margin ; hind-wings with two internal 

 nervures, unspotted, with broad dark borders ; abdomen ochre-yellow, with dark spots on the back. 

 The species are very closely allied, and vary from three-quarters of an inch to an inch in expanse. 



I. N. Ancilla (Linn.). — Fore-wings ochreous-brown, with three white transparent spots 

 beyond the middle, and often another spot above the inner margin before the middle; hind-wings 

 transparent, dusted with brown, in the male, and ochre-yellow in the female ; a broad brown border 

 in both sexes. It is found in dry, flowery woods in June and July in Southern and Central 

 Europe, but is rather local, and not very abundant. The larva is black, with yellow lines on the 

 back and sides. It lives on lichens growing on trees and rocks, in spring. (iV. Punctata, Fabr., 

 from South Europe and Western Asia, differs from the female of Ancilla in always having two 

 distinct white spots before the middle. Its varieties are numerous ; N. Scrvnla, Berce, is smaller, 

 with unspotted fore-wings ; N. Famnla, Freyer, resembles the male of Ancilla, but the spots of the 

 fore-wings are darker, and there are two spots before the middle of the fore-wings ; the hind-wings 

 are nearly transparent, as also in the variety Hyalina, Freyer, which has from two to four white 

 spots on the fore-wings.)
