342 BRITISH LEPlDOPTERA. 



of the cocoons is of a dull brown, the rim much paler. From the 

 inner edge of the rim the cocoon is regularly arched to the central 

 point, and somewhat plentifully covered with flossy silk, of a paler 

 brown colour than the body of the cocoon, although the cocoons look 

 quite smooth to the naked eye. The rim is also plentifully supplied 

 with loose flossy silk. [Described July 13th, 1898, under a two-thirds 

 lens, from cocoons sent t>y Dr. Wood.] 



Food-plants. — Salix russelliana and S. caprea (Wood), 8. fragilis 

 (Heinemann and Wocke). [Cambridge records {Ent., xxvi., p. 89) 

 the species from " birch " an evident error.] 



Time of appearance. — The species is single-brooded, appearing 

 in June, from larva? that feed up in August-November. Hodgkinson 

 records sweeping imagines from sallow, at Witherslack, June 9th, 1870. 

 Threlfall bred specimens June 20th, 1880, from larvae obtained the 

 preceding September and October, at Windermere. In Stainton's 

 collection are specimens captured on Dartford Heath, June 23rd, 1852, 

 and others bred by Threlfall, at Preston, May 18th, 1888. Cans- 

 dale obtained larvae in October, 1876, at Witham, that produced 

 imagines the following June. Wocke notes the imago as appearing 

 at the end of June, in Silesia, from October-November larvae, and 

 Nolcken records mines on September 24th, 1864, at Pichtendahl.

Original description. — Microsetia quinquella. Expansion of wings 

 2-2^ lines ; anterior wings deep black, with the base and three spots 

 silvery-white ; one placed towards the posterior angle of the inner 

 margin ; another on the costa near the base, and a third, somewhat 

 central, near the apex ; cilia silvery ; posterior wings and cilia dusky, 

 head black. It bears some resemblance to M. subbimaculella. I 

 found this beautiful and very distinct species in considerable plenty 

 on the trunks of oaks in the heath-field at West Wickham, on the 30th 

 of June last (1847) (Bedell, Zoologist, vi., p. 1986). 



Imago. — Head dark fuscous. Anterior wings 5-6 mm. ; dark 

 bronzy-fuscous ; transverse silvery spot on costa before middle of 

 wing ; a triangular silvery spot on inner margin beyond the middle ;
