850 THE ENTOMOLOGIST. 



Moults in the Odonata. — A perusal of the interesting notes by the 

 Eev. Arthur East, on the nymph of jEsclma cyanea, in the ' Entomo- 

 logist ' for October, prompts me to make a suggestion d propos of his 

 conjecture that " the smallest nymph skin measuring 3^ mm. must be 

 the first or second skin cast." A very few minutes after leaving the 

 egg, some young nymphs moult. This I have observed in Libellula 

 qnadrimaculata (at Jena, Germany, in June, 1896), and in our American 

 L. pnlchella and Sy))ipetrum vicinuni. It is also mentioned for Epitheca 

 himacnJata by Heymons (1896). It is likely that such a moult will be 

 found to occur in /Eschna. Previous to this first moult, the legs of the 

 young nymph are adherent to each other and are not movable, so that 

 Heymons says that we cannot yet speak of a larva, but of a hatched 

 embryo. The first moult frees the legs, which are at once put into use 

 by their possessor. — PmLip P. Calvert ; Philadelphia, Pa., U.S.A.,

Argynnis aglaia var. charlotta, Haxv. — Eeferring to the aberration 

 of Argynnis adippe described and figured {ante, p. 281), it is not a little 

 singular that the elongated silver blotches on the under side of the 

 hind wings are precisely identical in form with those in the var. 

 charlotta of aglaia, which Lang says used to be described by old 

 English authors as a distinct species, and was supposed to occur 

 nowhere else but in Britain. In 1884 I captured at Niederdorf, in the 

 Dolomites, a fine male example of this variety ; and Dr. Staudiuger 

 showed me two in his collection, taken in Germany. — E. S. Standen ; 

 Thorpe Hall, Colchester, Nov. 4th, 1900. 



[In Mr. Leech's collection there are three modifications of the 

 charlotta form of A. aglaia. These are labelled from the Engadine, 

 and two of these are of the male sex. All three have the basal silvery 

 spots on under surface of the hind wings confluent ; but the female is 

 fairly typical on the upper surface, and thus agrees with var. charlotta. 

 The male examples, however, apart from the confluence of the basal 

 spots referred to, exhibit different aberrational characters on both 

 surfaces. There is a figure of an aberration of A. aglaia closely ap- 

 proaching var. charlotta in the 'Entomologist ' for 1894, p. 182. — Ed.] 



Universal List of Entomologists. — Entomologists of all countries 

 are invited to send in their names, profession or business, order or 

 orders studied, and full address, to Ag. W. Norbeda, Entomologist, 

 Mehuk, Bohemia, who will be glad to insert such particulars, free of 

 cost, in his forthcoming ' Catalogue of the Entomologists of the World.' 



Epinephele tithonus in Large Numbers. — On July 30th last, 

 while wandering among the sandhills near Christchurch in Hants, I 

 found E. tithonus swarming on the bramble-bushes. The wind was 

 rather high, and they were generally on the protected side of the 

 bushes. On one fairly large clump I could probably have counted, 

 would they have remained still enough, a hundred specimens. This 

 butterfly seemed to be specially plentiful in the New Forest and 

 neighbourhood at the end of July and beginning of August. — W. J. 

 Lucas ; Sept. 12th, 1900.
