300 THE entomologist's record. 



then' quest in despair before ever giving me the opportunity for a 

 stroke. Add to this that the flight seems even more rapid and erratic 

 than that of A', nntiqua, and that the somewhat darker colour makes them 

 less conspicuous on the wing, so that I seldom saw them approaching 

 or departing, and it will be realized that I had pretty exciting sport. 

 When the flight was over, I introduced three males into the cage, and 

 two pairings were readily obtained. The previous removal of the 

 females from their cocoons seemed to be no obstacle. — Louis B. Prout,

Perizoma bifaciata (Emmelesia unifasciata) four winters in pupa. 

 — It is well known to breeders of Perizoma bifaciata (tinifasciata) that 

 it not infrequently passes three winters in the pupal stage, and the 

 fact has occasionally been recorded ; but I have never met with any 

 record for a longer period either with this or, so far as I can remember, 

 with any other Geometvid species. It may therefore be of value to 

 report that on August 2nd and 15th this year (1905) I bred two 

 perfect specimens from pupte which resulted from Sandown larvae 

 collected in 1901. My friend, Mr. .J. E. Gardner, also bred one earlier 

 this year (indoors) from a pupa which had passed the same abnormal 

 nuiBber of years. One cannot help suspecting that the wretched 

 summers of 1902 and 1903 may have had some influence in this, as 

 certainly an unusually large percentage of the 1901 stock went over 

 two and three winters. — Louis B. Prout, 246, Richmond Road, N.E.

Immigration of Pyrameis atalanta and Euchelia jacob^^. — There 

 has been an immigration of Pi/rameifi atalanta and Kuclielia jacobaeae 

 this year. That of P. atalanta was on a much smaller scale than that 

 of last year, but details concerning it and JhJ. jacobaeae would be very 

 interesting. Would entomologists who have observed movements of 

 these species in their districts please publish notes '? K. jacobaeae 

 appeared in inland localities near Chester-le- Street, Durham, during 

 the first week in June. This is fully sixteen miles from its nearest 

 habitat in Northumberland and Durham. Normally it is a coast 

 insect in these counties, and one can only rely upon taking it on the 

 Northumberland coast from CuUercoats to a little north of Wark worth.

Ovum of Melangaria galathea var. procida, and comparison with 

 THAT of M. galathea. — Upright Q§,g, fairly globular in shape, diameter 

 to length of inicropylar axis as 1 to 1-02. Micropyle on the 

 summit in a minute depression. The base, opposite the micropyle, has 

 a small but well-defined depression, on which the egg will stand 

 perfectly upright. Height l-17mm., diameter l-14mm. Colour, pale 

 whitish -buff, normally without markings, but many of the ova bore 

 ochreous, evidently accidental, stains. Smooth and dull to the unaided 

 eye. ScidptHre: The whole surface of the eg^ is very minutely pitted. 

 At the base of the egg little bosses may be observed like minute points; 

 from these run minute ridges which, about halfway up the walls of the 

 egg, arrange themselves into vertical lines. These lines soon commence 

 forming cells, either by branching out or running together. Gradually, 

 as the cells approach the summit, they become more and more clearly
