296 THE ENTOMOLOGIST. 



which was bred by Mr. Lewingfcon, of Market Kasen, the right side is 

 male and the left side female. So far as can be seen with the aid of 

 a strong lens, the bilateralism seems to extend to the sexual organs, 

 so that gynandromorphism is complete. Dorfmeister (Stett. Ent. 

 Zeit. 1868, p. 181), theorising upon the origin of gynandrous speci- 

 mens of Lepidoptera, suggests that part of a male germ and part of a 

 female germ come together in the formation of the egg which is 

 destined to produce a gynandrous example. Consequently, wherever 

 one such specimen appears in a brood there should be another similar 

 one resulting from the other parts of the two germs. As a test of the 

 soundness of his views, he proposed that experiments should be tried 

 by breeding whole broods from the egg, and instanced Ocneria dispar 

 and Lasioccniipa quercifoUa as suitable species for the purpose. Further 

 information on the subject will be found in a paper entitled " Uber die 

 hermaphroditische Anlage der Sexual driisen beim Mannchen von 

 Phyllodromia yermanica," published in 1890 (Zool. Anz. xiii. 451-457). 



Gynandkous example of Lyc^na ICARUS. — A specimen of L. icarus, 

 sent to Mr. Sabine from Dover, has the left wings male in character on 

 both surfaces, but the right wings are those of a female, the upper 

 surface being coloured bright blue as in var. cmnilea. The orange 

 lunules on the upper surface of the right fore wing are present, but not 

 clearly defined, whilst those of the right hind wing are partly absent. 



Leucorrhinia dubia, var. — All the wings suffused with smoky 

 saffron, the suffusion strongest at the wing bases, and weakening 

 gradually towards the margins. A specimen taken on Whitegate 

 Heaths (Delamere Forest), June 5th ; the only one I have ever cap- 

 tured. — J. Arkle ; Chester. 



AcosMETiA MORKisii, Morris. — With regard to Dr. Knaggs's note on 

 this insect {ante, p. 256), I should like to call attention to the fact that 

 Mr. Meyrick has simply accepted the conclusions arrived at in Tutt's 

 ' British Noctuae,' vol. iv. pp. 99--100, where a discussion of the matter 

 will be found, which has apparently been overlooked by Dr. Knaggs. 

 It appears to me that, even if Morris's original description is inadequate, 

 the work of Humphreys and Westwood should not be left out of con- 

 sideration.— Louis B. Prout; 246, Eichmoud Road, N.E., Oct. 8, 1897. 



White Female of Colias chrysotheme near Vienna. — On Aug. 25th 

 last, when I was collecting C. chrysotheme on the high ground above 

 Modling, in the neighbourhood of Vienna, I was fortunate enough to 

 take one white female, freshly emerged and in perfect condition, as 

 indeed were most of its more gaily-coloured, if less interesting, com- 

 panions. There was no doubt as to its identity, as neither C. edusa nor 

 C. myrmidone were flying in that locality, and it resembled the other 

 females exactly in size, shape of wings, and markings. About a week 

 later I had the pleasure of a few minutes' conversation with Dr. 

 Staudinger at Dresden, and upon making inquiries from him respecting 

 this insect he informed me that a white variety of C. chrysotheme had 

 never before come under his notice ; it had no name, and he did not 

 possess one in the whole of his immense collection. However, he said 

 as this form occurred not unfrequeutly among other species of this 

 genus, there was no reason why G. chrysotheme should be an exception.
