NOTES AND OBSFJRVATIONS. 157 



are normal except one ab. uigrlna from the Spilsbury Collection 

 and one intermediate with a portion of the white band clouded 

 with black, from near Beading, taken July 17th, 1919, by the 

 Rev. C. F. Thornewill. 



Polygonia c-album. — Series of over 80, without any very 

 remarkable aberrations. There are 7 ab. hutchinsoni from 

 Leominster. Much variation is shown in the undersides, from 

 an almost unicolorous very dark brown to the light, well-marked 

 pale brown of ab. hutchinsoni. 



Eagonia polychloros. — Series of more than 50, with no 

 extreme aberration. A very large specimen from the Champion 

 Collection, taken in the Isle of Wight, August 6th, 1909, has 

 a rather broad black margin to the hind wings adjoining the 

 blue lunules, which are very large and bright. 



{To be continued.) 



NOTES AND OBSERVATIONS. 



Variety of Euchloe cardamines. — One out of two pupse only 

 which I had this year produced a tine (^ , with a conspicuous black 

 discoidal spot on each hind wing, and the spots on the fore wings 

 are unusually large. Although I have specimens, both (J and 9 . 

 with black dots more or less developed in the hind wings, I have 

 never seen one approaching this bred specimen as regards these 

 markings. — F. W. Frohawk. 



Asymmetrical variety of Pieris napi. — The only butterfly seen 

 in my garden on March 29th last, a dull and chilly day, happened 

 to be an asymmetrical specimen of Pieris na^n, a (^ , very perfect, 

 and apparently only just emerged. The left primary has a large 

 black central spot, which is represented on the right side by a faint 

 dot only; the apical blotch is also less developed than that on the 

 left side, as well as the costal blotch on the secondary. ' It forms 

 a striking aberration. A precisely similar type of variation exists 

 in a specimen of P. rapce in the Hon. N. Charles Rothschild's 

 collection. — F. W. Frohawk. 



Unusual variety of Aglais urtic^. — On May 9th last I 

 captured a very unusual variety of Aglais urticce in my garden (as 

 it sometimes happens the only specimen seen). I noticed as it 

 flew past me it looked somewhat dark; it soon settled on a strawberry 

 blossom, and seeing it was abnormal I fetched my net and captured 

 it. The ground-colour is rich and deep, the normal yellow costal 

 blotches reduced in size, and the outer one almost obliterated by 

 brown scales, the basal blotch clouded with red, the subapical white 

 mark replaced by greyish-buff ; the two central black spots are 

 missing except a mere trace of the lower one on each primary, 

 indicated by a few black scales. There is no sign of the usual blue 

 mai'ginal spots on either the primaries or secondaries ; the latter 

 wings are unusually dark. The specimen is in such perfect condition
