(2.) Ground-colour grey, with dorsal and sub-dorsal lines, and wing-cases, as in 

 var. 1, but the spiracles always very indistinct. 



(3.) Ground-colour bright green, with no stripes, the abdominal incisions 

 slightly paler, the wing-cases of the same green colour, and no longitudinal striae. 

 The spiracles whitish. 



(4.) Ground-colour unicolorous pink, with whitish wing-cases. The spiracles 

 very indistinct. 



These were described when the pupa-cases were well set. All 

 the above varieties assume a dark appearance just before emergence. 



The imagines first began to appear on June 2nd, and between 

 that date and July 1st, I bred above 120 specimens. There appears 

 to be some difference in the colour of the imagines, and I am inclined 

 to suppose that the larval and pupal variation is continued into the 

 imago state, as some specimens are more distinctly rosy and strongly 

 marked than others ; some being distinctly whitish-grey, some quite 

 strongly reddish-ochreous in colour. 



From some of the later of these moths I have reared a second 

 brood, and proved that the "fluff-mining larva," which Mr. G-regson 

 considered might prove the continental species farfarella,Zel\. (Entom., 

 xviii, p. 151), is only, as I then suggested it might be, the second 

 brood of gonodactyla. 



May I kindly refer those who are interested in this species to 

 Entom., xviii, p. 151 ; pp. 169—172 ; pp. 195, 196 ! 



The above notes on variation may throw a side light on the 

 plagiodactylus group, the so-called species of which appear principally 

 to differ in the ornamentation of the larva, i. e., either in the depth or 

 quantity of colouring matter and general extent of suffusion. 



Westcombe Park, S.E. : 



September 4th, 1888. 



Choerocampa celerio at Reading. — On the 3rd instant a perfect specimen of 

 Choerocampa celerio was brought me alive by Mr. G. Philbrick of this town, who 

 had just taken it in his garden. — W. Holland, Reading : August 17th, 1888. 



Protective resemblance in larva of Stauropus fagi. — I picked up a full-fed larva 

 of Stauropus fagi on the path in a beech wood the other day. It very closely re- 

 sembled a curled-up beech leaf like those beside it on the path. — Id. 



Occurrence of Argynnis Paphia (var. valezina) near Reading. — I have taken 

 two specimens of Argynnis Paphia (var. valezina) at Hardwick Park, near here, this 

 month. It seems rather later than the type form. It appears to be extending its 

 range, although among the hundreds of Paphia on the blackberry blossoms at 

 Odiham "Wood, Hants, I never saw a specimen. — Id.
