third segment. This is also rare. I\Ir. BigncU sent, nie a pair some years ago bred 

 from Orgyia pudibunda, and Mr. Dale has one in his collection reared from the 

 same insect.

This is also closely related to the two preceding species, but differs from them 

 both by having the middle abdominal segments armed with discal setae; it resembles 

 E. lucorum by having the arista long and slender, and only slightly tliiekened at the 

 base, but has a i-ather narrow frontal stripe as in E.gnava. Not uncommon. It is 

 in Miss Deeie's as well as Mr. Dale's collection, and Mr. Inchbald sent me several 

 specimens which he bred from Arctia caja and A. lubricipeda.

Calliphora erythrocephala, Mg.,from a wasp's nest. — At page 170 of the June 

 (1891) number of the Ent. Mo. Mag., Mr. Bignell mentions the breeding of Homa- 

 lomyia canicularis from an old nest of Vespa vulgaris ; he was good enough to give 

 me some of the pupae taken from the nest, amongst which were three more than 

 twice the size of the others, and from these emerged three fine specimens of Calli- 

 phora erythrocephala, Mg., one of the two species which are usually classed together 

 as " blow-flies." The smaller pupae all produced Homalomyia canicularis, L., but 

 no hyper-parasites. — Coktndon Matthews, Ivybridge : Novemher 9th, 1891. 



Interesting variation of Pieris napi in Ireland. — To my kind friend Mr. Percy 

 E.USS, of Sligo, we are indebted for almost all we know of the interesting forms of 

 Lepidoptera to be found in that district, and now he has made what I think is 

 another distinct addition to our knowledge. There is found in the Alps a well 

 known and most striking dark variety of Pieris napi, called hryonice, in which the 

 nervures on the upper-side of fore- and hind-wings are very broadly bordered with 

 dark scales in such a manner that the insect, which is of a brownish-yellow ground- 

 colour, is almost covered with broad, dark grey, longitudinal stripes. Mr. Russ has 

 now sent for my information specimens of female napi, in which the nervui'es of the 

 upper-side are broadly scaled quite to the hind-margins of the wings in the same 

 manner, and only differing in the ground-colour, which is yellowish-white. This 

 variety differs greatly from the forms with black nervures and apices from ihc north 

 of Ireland, and is quite the nearest approach to var. bryonicB which has come under 

 my observation in these islands. — Chas. G. Barrett, 39, Linden Grove, Nunhead :

Varieties of British butter flies. — Among the specimens sent from Sligo by Mr. 

 Kuss I find worthy of special notice : Pieris brassicce, $ , of large size, much suffused 

 with grey, with a very broad black apical blotch, from the inner edge of which black 

 streaks run to the uppermost black spot. Pieris rapce, $ , pure white, hardly a trace 

 of even the apical dark blotch. Satyrus Semele and Epinephile t7aMJra, males, with 

 the blotches of pale colour above, as in the females, though smaller. Vanessa 

 cardui, of an exquisite rosy colour, and Polyommatus Alexis, males, of very pale 

 blue, from abundance of brilliaiil silvery-white hairs, and with decided round dots,
