170 BEITISH LEPIDOPTEBA. 



The females, he says, rest with uplifted ovipositor on the case, and 

 immediately after copulation, commence to fill the larval case with 

 eggs. Copulation only lasts a few minutes, and during this time the 

 male closes his wings roof-shaped ; unfertilised females will sit for 

 several days on their cases and dry up without laying eggs. This 

 statement as to the S. inconspicuella with winged males, suggests 

 that there is a marked physiological difference between the female of 

 this and that of the parthenogenetic S. lichenella, for the latter will 

 almost directly on emergence insert its ovipositor in the larval case, 

 and lay its eggs as rapidly as possible. 



Time of appearance. — The imago appears from late March to 

 early May. March 10th, 1851, bred from cases found on Penge 

 fence on February 23rd ; March 2Sth-30th, 1852, bred, cases from 

 Penge ; May 20th, 1857, imagines, on Beckenham fence (Stainton) ; 

 specimens in Stainton's collection, labelled douglasii, referable to incon- 

 spicuella, were captured (or bred) March 8th. 1858, from cases on grit- 

 stone, taken in Lancashire by Gregson ; April 5th-8th, 1S59, near Man- 

 chester, May lst-20th, at the Brushes, April lst-12th, 1859, imagines 

 from pupas kept out of doors, from Bowdon (Edleston) ; cases and pupae, 

 April, 1857, at Bristol (Vaughan) ; females bred May, 1873, from 

 larvaa collected October, 1872, at Worcester, further supply of larva? 

 obtained June, 1873 (Edmunds) ; April 26th-May 7th, 1886, most 

 abundant on May 3rd, bred May 6th, 1886, from captured cases, 

 imagines May 7th, 1887, April 17th-May 7th, 1888 (and probably 

 later), at Brentwood (Burrows) ; May 11th, 1888, on fence at Bexley, 

 April 10th, 1894, beaten from juniper at Box Hill (Bower) ; 

 March 31st, 1894, $ , flying at 6 p.m., at Tarrington (Wood) ; first 

 week in April, 1896, $ , flying in morning sun, at Hereford (Tutt) ; 

 April 3rd, 1899, males beaten from trees at Lyndhurst (Smith) ; a few 

 cases on trees in February near Doncaster (Corbett). [Beutti says " in 

 May and June in Baden," the " June " reference is suspicious.] The 

 imagines emerge at the end of March ( $ s and J s in equal numbers) 

 near Batisbon (Hofmami).

 we have never taken it."
