1892, July 23rd, 1897, at Aylsham, August 10th, 1896, August 15th, 

 1898, exceedingly abundant at Prescot (Freeman) ; August, 1892, at 

 Folkestone (Bryne) ; larva? August 13th, 1892, August, 22nd, 1894, 

 August 3rd, 1896, August 23rd, 1897, at Bristol, August 31st — Septem- 

 ber 3rd, 1892, August 9th — 30th, 1896, at Braunton (Bartlett) ; larvae 

 on sallow, September 23rd, 1892, at Newbury (Beales) ; fullfed at 

 Frimley, July 20th, 1893 (Newland) ; July 27th — 31st, 1893, at 

 Wicken Fen (Bouskell) ; August 10th, 1893, on sallow, September 

 5th — 8th, 1894, at Enniskillen (Brown) ; remarkably abundant in 

 August, 1894, on Strensall Common, where the sallow, bushes are 

 small and isolated ; this autumn (1894) an excess of larvae on one of 

 the bushes had resulted in its being stripped before some of the larvae 

 were fullfed, and, having vacated it for pastures new and failed 

 to find another bush near, some 40 or more larvae were found 

 crawling on the ground in its neighbourhood ; also very common 

 in the York district on young apple-trees in gardens and on crab- 

 trees by the roadsides \ S. Walker) ; July 14th, 1895, August 20th, 1900, 

 at Sudbury, August 28th, 1895, at Bulmer, August 18th — 21st, 1899, 

 August 26th, 1900, at Henny (Ransom) ; larvae September, 

 1895, August 28th, 1898, at Oxton (Studd) ; August 22nd, 1896, 

 larva pupated August 29th, 1896, at Chester (Arkle) ; September 

 3rd, 1897, at Kirkbride, September 1st, 1898, in Ballaugh-Curraghs 

 (Clarke) ; July 23rd, 1899, fullfed larva at Reading (Reece); larvae 

 August 21st, 1899, at Limbrick Lanes (Whittaker) ; July 28th, 1900, 

 larvae half-fed on sallow at Stoke Wood, Oxshott (Pickett) ; August 

 24th, 1900, at Hampstead (Hopson) ; eggs hatched June 9th, 1901, 

 larvae fullfed July 23rd, 1901, and following days at Henley-on- 

 Thames (Stearns). 



Larva*. — First stadium: The larva is much shorter and stouter 

 than that of Mimas tiliae ; the head is generally round like that of 

 the last-named species (although there is some variation in this 

 respect, Poulton remarking that, in a brood of young larvae that he 

 reared, he was surprised to find a few of the newly-hatched larvae 

 with heads of the typical Amorphid shape). The caudal horn is 

 about one-third the length of the larva, appears black to the naked 

 eye, but under a lens is seen to be of a deep pink, the black colour 

 being due to the hairs. When full-grown in this stadium the 

 oblique stripes are quite distinct, and the subdorsal is also clearly 

 developed on abdominal segments 2 to 5. (In one young larva, 

 the subdorsal was continued throughout its whole length ; it was 

 very distinct in the 2nd instar, and could still be traced in the final 

 stage.) Second stadium : The head is now roughly triangular, 

 almost of the form of that of the mature larva ; on the apex there 

 are similar processes to those seen in the larva of M. tiliae, but 

 they are red instead of yellow ; the lines up the sides of the head 

 are quite distinct in this stage. The body has a very rough 

 appearance, due to the large size of the mammillae of the shagreen 

 hairs ; the 7th stripe is continued some way up the horn, 

 and the latter is now very little longer than the thickness of the 

 body ; the anal flap outlined with a yellow stripe. Third stadium :
