ochraced, its type (according to Merton Rule 48) is auwrayo, Fb., as ita a 
first use by Stephens in his 1850 list (p. 125) is for subgenus c of@ 
NXanthia (aurago alone). As it is not yet proved that awrago is con- 
generic with citrayo, Li. (personally I have very grave doubts as to this 
union), we shall do well to use (provisionally) the name Ochria for 
auraygo and to retain Tiliacea, Tutt, for citrago, and not to sink Tiliacea 
before Ochria until further information is available.-—Lou1s B. Prout,

Cross-PAIRING OF SMERINTHUS POPULI AND §. oceLLATUs.—I tried 
this season the experiment of cross-pairing S. populi and S. ocellatus. 
T had no trouble to get them to pair as they copulated freely when ag 
and @ were isolated. Three females laid about 500 ova, but not a 
single one hatched.—H. Aupzrson, F'.E.8., Hilda Vale Road, Farn- 
borough. July, ee 1900.

BLACK ABERRATION OF XYLOPHASIA MONOGLYPHA (poLyopon) AT Tiny. 
—It may be worth recording that last night, while sugaring here, I 
took Xylophasia monoglypha (polyodon) quite black. I thought these 
aberrations were only taken in Scotland. Has it ever been recorded 
for the eastern counties before ?—W. J. Cross, Ely. July 6th, 1900. 
(In British Noctuae and their Varieties, vol. i., p. 74, a few southern 
localities are given for ab. infuscata, White, including Tenby, Sheerness 
and Deal. The ab. aethiops, Staud., has been recorded from Sligo, the 
Lancashire coast, Glasgow and Aberdeen, but from no more southern 
localities. We may add that our knowledge as to the causes of certain 
forms of variation are much hampered by want of records of the 
distribution of various forms of common or comparatively common 
species, and until our collectors haye determined the geographical 
range of the various forms, generalisations bearing on their origin are 
almost sure to be at fault.—Kb. | 
GYNANDROMORPHOUS EXAMPLE oF Dryas papaia.—A fine specimen 
of Dryas paphia, which was captured near Lyndhurst, New Forest, on 
July 25th, seems to be worth recording. The right wines are those 
of a @ var. valesina, the left wings ordinary type of g with the © 
exception of a dark splash resembling ralesina-colouring on the fore- 
wing. I should be pleased to learn whether this peculiar form of 
gynandromorphisin has ever occurred before. The specimen is now 
in my cabinet.—W. I*. Urwickx, 34, Great Tower Street, London. 
August 17th, 1900. [For similar aberrations see Wiskott, Die 
Jiepidopteren-Awitter seiner Sammlung, pp. 17, 18, where two are 
recorded—left wings 2 ab. valesina, right wings 3 typical paphia. 
There are also we believe some British records. —Ep.] 
Aserration or Arcria cata.—l bred this year a very fine aberra- 
tion of Arctia caia from a wild larva collected with many others a few 
iniles from here. The forewings are entirely dark brown with the 
exception of four minute white ‘streaks near the base, the hindwings 
and body are nearly black, the usual red of the remaining evound 
colour being replaced by a dull ochreous-yellow. The specimen 
emerged on 7 uly 18th, and is a female, rather undersized, but perfect.—
