NOTES. 



ZOOLOGY. 

 An Aberration of Arg-ynnis aglaia. 



I send a description of an interesting aberration of Argynnis aglaia 

 which my son, W. G. Crawford, caught among the sand-hills bordering 

 the Bush River at Portballantrae, Co. Antrim, at end of August, 1919. 



Female. Expanse 2^ inches. Uppers: de. — Fore wing mostly black 

 with a fulvous spot about middle of the cell. Basal area dusky brown, 

 terminal area fulvous crossed by thickened black veins. Cilia cream 

 except where interrupted by the black veins. Hind wing. Basal area 

 dusky brown ; fulvous patch stretching from costal margin across cell 

 with halved black spot superimposed on it ; outer area mostly black, 

 dusky fulvous showing only in the interspaces. Cilia as in fore wing. 

 Underside. — Fore wing, fulvous with thin black bar across base of 

 cell, large roundish black spot in middle of cell and broken black bar 

 across apex of cell ; disc almost wholly black with veins fulvous, terminal 

 margin fulvous with subterminal brown line marked with silvery blue 

 on the inner side in interspaces 5, 6, and 7. Hind wing, ground colour 

 green marked by usual silver blue spots, mostly edged with black. The 

 discal spots in interspaces 5, 6, and 7 are entirely black. Yellowish 

 spots in interspaces 2, 3, and 4 between the discal and subterminal rows 

 of silvery spots.

Return of the Golden-crested Wren and Long-tailed 

 Titmouse. 



As stated {Irish Nat. vol. xxvi., p. 118) the severe winter of 191G-17 

 practically, if not entirely, exterminated the Golden-crested Wren and 

 Long-tailed Titmouse in this district. In regard to the former species, 

 after the lapse of about a year a few appeared again, and now this bird 

 has about regained its former status. Until November, 1920, the Long- 

 tailed Titmouse was not noted here, but I am glad to report that on the 

 24th of that month Mr. C. B. Horsbrugh saw a pair in his garden, and 

 on the following morning I observed them also.
