284 MEMSTIC VARIATION. [part I. 



the missing leg had been broken off or whether the extra wing was in 

 its place. Westwood, ibid., p. 220. 



A specimen of G. rhamni having five wings was caught at Brandon, Norfolk, in 

 Aug. 1873 by Mr J. Woodgate, and exhibited to the Ent. Soc. by Prof. Meldola, 

 Proc. Ent. Soc. , 1877, p. xxvi. A similar specimen of this species was bought at 

 Stevens's auction-rooms and exhibited to Linn. Soc. by Prof. C. Stewart, in April, 

 1891. This specimen is now in Mus. Coll. Surg. Whether it is the same as that 

 taken by Mr Woodgate, or that described by Westwood, or not, I cannot say, but 

 possibly the references are all to one individual. 



428. Lycaena icarus <f. A coloured figure is given of a specimen 

 of this form with 5 wings from Taurus, Asia Minor. [No further 

 description is given. The figure is not very clear. It shews 

 however that all the wings are normal except the right anterior. 

 This wing is represented by two wings, which together are about 

 a third wider than the normal wing. The costal portion of the 

 foremost of these wings appears to be nearly normal in neuration, 

 and the posterior part of the hindmost seems to be also normal. 

 The two taken together shew several supernumerary nervures 

 as compared with the normal wing, but the details are not 

 shewn with sufficient clearness to justify a more precise statement.]

429. Bombyx quercus $ : specimen having 5 wings figured in 

 colour by Honrath, with statement that the left anterior wing 

 shews a double structure. [No further description given. The 

 figure shews the left anterior wing represented by two wings. 

 Of these the posterior appears to represent a nearly complete 

 anterior wing on a reduced scale. It bears the white ocellar mark 

 of the anterior wing. The pale-yellow submarginal band is 

 curved inwards over the ocellus upon the costal border as in a 

 normal wing and thus shews that the foremost wing is not merely 

 the separated costal part of this wing. The foremost wing is 

 anomalous. Its central half is rather darker in colour than that 

 of the normal wing and its peripheral half is pale in colour, 

 deepening towards the margin. It bears no ocellus. The neura- 

 tions cannot be made out from the figure with precision but the 

 two wings together contain many more nervures than the normal 

 anterior wing. The legs are not described.] Honrath, E. G., 

 ibid., fig. 10. 



430i Zygaena minos, having a fifth wing on the left side, inserted above and between 

 the normal wings. The neuration of this wing is peculiar. The colouring of the 

 supernumerary wing was that of the anterior wing. [Dr Rogenhofer kindly informs 

 me that the legs were normal.] Rogenhofer, A., Sitz.-Ber. d. zool.-bot. Ges. Wien, 

 1883, xxxn. p. 34, fig. 



In the same place the following instances of five-winged Lepidoptera are given : 



431 Ortliosia lnovis with an additional posterior wing on the left side, in the 

 Museum of Pesth. Treitschke, Bel. vi. Abth. n. p. 407. 



432 Pygsera anastomosis with a wing-like appendage to the left anterior wing in 

 ' the collection of Ochsenueimer in Pesth. 



433. Naenia typica with an additional posterior wing in the collection of Neustadt 

 at Breslau.
