10 mm. ill length, and enclosed in a dense silken web between 

 the leaves where the larva had fed. 



The imago is easily recognized by the bright orange colour 

 of its hind wings. The male measures from 15 mm. to 16 mm. 

 in expanse. Fore wings rich greyish brown, reticulated with 

 darker brown, with a broad deep red- brown fascia from the 

 middle of the costa, where it is narrowest, to the inner margin, 

 where it broadens out, extends to the anal angle, and unites with 

 an irregular triangular patch of the same colour that occupies 

 the apical and hind marginal areas. Hind wings bright orange 

 bordered with black, usually with a few black scales scattered 

 along the veins ; but in one of the specimens reared, they are so 

 dense as to almost obscure the orange colour of the wing. Cilia 

 orange. 



The female is a larger and more sombre insect. It measures 

 18 mm. to 22 mm. in expanse, is slightly paler in colour than 

 the male, and the reticulations more clearly defined. The brown 

 fascia is of a duller and less reddish tone, and its central portion 

 is often indicated only in outline, as is also the triangular patch 

 of the apical region. The body in both sexes is ringed with 

 yellow. 



The imago emerges during September and October, and its 

 time of flight appears to be in the morning sunshine between 

 eight and ten o'clock.

THE GENEEIC NAME SCOPULA. 

 By Louis B. Prout, F.E.S. 



When I wrote on the correct names for the genera formed 

 from the old " Acidalia'' (Entom. xxxviii. pp. 7-8), I entirely 

 ignored Scopida, Schrank (' Fauna Boica,' ii. part 2, p. 162). 

 Although I have long been acquainted with the (apparently over- 

 looked) history of the inception of this genus, I " hoped against 

 hope " that some loophole might be found for escape from its 

 adoption in a corrected sense. However, on looking into the 

 matter again, I am convinced that there is no such escape, and 

 it will therefore be a loss rather than a gain to postpone the 

 inevitable any longer. The genus was erected for two species 

 only — (1) paludalis (= paludata, L. = oniata, Scop., certo) and 

 (2) deiitalis, Schiff. For those few extremists who take the first 

 species to be the type, whether it agrees with the diagnosis or 

 not, this will be decisive in favour of ornata ; but what will carry 

 more weight with the majority is that the generic diagnosis fits 

 only this species. Treitschke, in 1828, was therefore idtra vires
