NOTES AND OBSERVATIONS. 125 
October, 1917, p. 235). Aglais urtice : Two very pale examples, one 
almost white, both of which I took in the same field in 1918 and 1919. 
Melanargia galatea: One specimen, difficult to describe, with the 
black patches distributed very irregularly. I took it last year on 
Bucks Chilterns. Epinephele jurtina (janira): Several bleached 
? 2 last year; g J partially so. Pararge megera and P. egerides : 
Both these are now well represented, but prior to 1918 I had not 
found them. Canonympha pamphilus : My best aberration may be 
included here. I tookit on the hills near Aldbury in June, 1918. All 
wings of a dull mahogany-brown ; gives the appearance of the next 
species.* The underside is a very rich deep brown. Last year several 
bleached examples, and a curious one having three wings normal 
and one pure. white. Chrysophanus phleas: Two specimens with 
all wings pale metallic yellow, in same field, curiously enough, where 
I took the pale wrtice. Aricia medon: An obsolete underside last 
last year on Bucks Chilterns. Agriades corydon: Several sem- 
syngrapha near Halton and Aldbury last August. Two somewhat 
striated undersides and a semt-obsoleta in 1919 and a grey ¢. 
Cupido minimus : Out of hundreds examined, one obsolete underside, 
Bucks Chilterns, 1920. Nisoniades tages: A very remarkable aber- 
ration last year at Dancer’s End. All wings of a pale straw, one side 
being almost white. I would like to know if any of your readers 
have seen other brown specimens of pamphilus as I find no mention 
of it in my books.—A. L. Goopson; Park Road, Tring, Herts. 
ZEPHYRUS QUERCUS AB. OBSOLETA.—As varieties of Zephyrus 
quercus seem to be very rare, it will perhaps be of interest to mention 
that I took a 2 of this insect at Arnside, Westmorland, on August 
18th, 1920, in which the usual blue patch is almost completely absent, 
being represented only by a few scattered blue scales, almost invisible 
at a casual glance. It seems to be referable to ab. obsoleta, Tutt, of 
which the latter only records one specimen, bred by Mr. Raynor at 
Hazeleigh.—G. H. E. Hopxins ; Shevington Vicarage, near Wigan. 
Pieris RAPH, AB.—During July and early August of last year I 
took a fairly long series of Pieris rape at Finchley, and on examina- 
tion after they were set I discovered among the females a form 
having a blackish-grey spot in the discal area of the hind wings. I 
found four examples of this aberration in the series of forty-two 
females I had set—roughly 10 percent. Two of the four have the spot 
well-developed and distinct; the other two have it indicated by a 
cluster of black scales. This spot is situated between veins 3 and 4, 
and is placed about one-third the distance up from the margin to the 
base of the wing. I notice the specimens bearing this spot have 
the other black markings somewhat heavier than normal summer 
females. I exhibited these specimens at the South London Ento- 
mological and Natural History Society on October 14th last, and since 
then two of the members have told me they have looked through their 
series and found they had examples similar to mine. As far as I am able 
to trace this form does not appear to have been described or named, and 
as it seems to be an aberration that is not uncommon I, suggest it 
should be called niyropunctata. Since writing the above I find Mr. 
Frokawk gives a very excellent figure of this form in his ‘ Natural 
* Dark form of C. tiphon (davus).
