2. M. bipunctidactylus, Hav-. ; serotinus, Zell.— 

 Expanse J to 1 inch. Fore wings narrow, grey-brown or pala 

 brown, costa dusted with black ; two small black dots before 

 the fissure and another half way to the base. Hind wings 

 dull brown with a purplish flush. 



AntenntB of the male slender, simple, short, brown ; palpi 

 shortly triangular, pale brown, whiter above; head and 

 thorax drab-brown ; abdomen very slender, light brown, 

 paler still at the base and at the anal tip. Fore wings narrow 

 the lobes near together ; costa almost straight till very near 

 the apex, there arched a little ; apex of each lobe narrowly 

 yet bluntly, angulated ; anal angle also blunt ; grey-brown 

 or drab-brown, the costa darker but the nervures often dusted 

 with red-brown ; just before the middle is a black dot in the 

 discal cell, and immediately before the fissure two more, 

 placed one over the other ; two or three much smaller 

 lie ujDon the hind margin ; cilia pale brown mixed with 

 white. Hind wings, and the cilia of the three lobes, glossy 

 golden-brown or purplish-brown. Legs very long and thin, 

 almost hair-like, pale drab, whiter on the inner side. Female 

 similar. 



Underside wholly glistening pale brown, or pale reddish- 

 brown. 



Variable, to pale drab almost without indications of the 

 markings — which form has been erroneously supposed to be 

 the species named M. a rid us abroad — and on the other hand 

 to increased size and a browner colouring, with very small 

 black dashes in the lobes of the fore wings, or a bordering 

 of white between them, or both. In chalky districts, and more 

 particulai'ly in the north-west of England, this tendency 

 becomes exaggerated, the costa above the fissure is blackened, 

 so as sometimes to form a flattened dark triangle with the 

 usual two dots at its apex, these dots are also joined together
