242 THE entomologist's record. 



ochracea, its type (according to Merton Eule 48) is auraijo, Fb., as its 

 first use by Stephens in his 1850 list (p. 125) is for subgenus c of 

 XantJda [aurarjo alone). As it is not yet proved that aurago is con- 

 generic with citrcujo, L. (personally I have very grave doubts as to this 

 union), we shall do well to use (provisionally) the name Ocliria for 

 aurafio and to retain Tiliacea, Tutt, for citrcu/o, and not to sink Tiliacea 

 before Ocliria until further information is available. — Louis B. Prout, 

 F.E.S., 246, Eichmond Eoad, N.E. July Qth, 1900. 



Cross-pairing of Smerinthus populi and S. ocellatus. — I tried 

 this season the experiment of cross-pairing S. populi and S. ocellatus. 

 I had no trouble to get them to pair as they copulated freely when a S 

 and $ were isolated. Three females laid about 500 ova, but not a 

 single one hatched. — H. Alderson, F.E.S., Hilda Vale Eoad, Farn- 

 borough. July, SOth, 1900.

Black aberration of Xylophasia monoglypha (polyodon) at Ely. 

 ■ — It may be worth recording that last night, while sugaring here, I 

 took Xylophasia monoylypha {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 Qth, 1900. 

 [In British Koctuae and their Varieties, vol. i., p. 74, a few southern 

 localities are given for ab. infuscata. White, including Tenby, Sheerness 

 and Deal. The ab. aetkiops, Stand., 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 have determined the geographical 

 range of the various forms, generalisations bearing on their origin are 

 almost sure to be at fault. — Ed.] 



Gynandromorphous example of Dryas paphia. — A fine specimen 

 of Dryas paphia, which was captured near Lyndhurst, New Forest, on 

 July 28th, seems to be worth recording. The right wings are those 

 of a 5 var. valesina, the left wings ordinary type of ^ with the 

 exception of a dark splash resembling ralesina-colonnng on the fore- 

 wing. I should be pleased to learn whether this peculiar form of 

 gynandromorphism has ever occurred before. The specimen is now 

 in my cabinet. — W. F. Urwick, 34, Great Tower Street, London. 

 August nth, 1900. [For similar aberrations see Wiskott, Die 

 Ijepidopteren-Zuitter seiner Sammluny, pp. 17, 18, where two are 

 recorded — left wings ? ab. valesina, right wings <? typical paphia. 

 There are also we believe some British records. — Ed.] 



Aberration of Arctia caia. — I bred this year a very fine aberra- 

 tion of Arctia caia from a wild larva collected Avith many others a few 

 miles from here. The forewings are entirely dark brown Avith the 

 exception of four minute Avhite streaks near the base, the hindwings 

 and body are nearly black, the usual red of the remaining ground 

 colour being replaced by a dull ochreous-yelloAv. The specimen 

 emerged on July 13th, and is a female, rather undersized, but perfect. —
