194 [August. 



collecting at Chmin Loch, foiu' miles to the west of Blairo^owrie, on June 13th, 

 I took a single ^ example of Porphyrops nasuta, Fall., a species added to the 

 British List by Mr. Verrall in the volume of this Magazine for 1894, p. 141, 

 upon a ^ specimen, without data (but probably taken at Deal), in the late Dr. 

 P. B. Mason's collection. From Mr. Verrall's •' List of British Dolichopodidse " 

 (Ent. Mo. Mag., 1905, p. 112) I gather that the species has not been met with 

 again, and the present record is therefore of some interest as further establishing 

 the claim of the species to a place in our List. 



Porphyrops clegantula, Mg., occurred at the same spot in some numbei'S and 

 in both sexes, but most of them rather worn. This is another rare species, and 

 I am glad to add it to the Perthshire List, as I know of no other record beyond 

 the two given by Mr. Verrall, Tarrington and Aviemore (Col. Terbiiry). Both 

 species are easily identified from Mr. Verrall's valuable paper before referred 

 to. — A. E. J. Carter, Blairgowrie : June, 1910. 



Time of emergence of Neiv Zealand Lepidoptera. — In studying the habits of 

 some of the Lepidoptera native to this country, I have been much struck with 

 the fact that the emergence of the imago seems almost invariably to take place 

 during the hours of darkness, the only exceptions I know of being the butter- 

 flies, and a day-flying moth, Nyctemera annulata, Boisd., which is distastefvil to 

 birds. This habit would appear to be an important factor in the preservation 

 of the species, as it affords the individual protection from the attacks of in- 

 sectivorous birds at a very critical stage of its existence, by giving time for the 

 wings to expand and harden, and for any protective coloration or structure to 

 come into operation, before the birds are astir. 



It Avoixld be interesting to know if similar habits have been observed among 

 the Lepidojitera of other lands. — E. M. Stjnlet, Macdonald Street, Karori,

The South London Entomological and Natural History Society : 

 Thursday, June 9th, 1910.— Mr. J. W. Kaye, F.E.S., President, in the Chair. 



Mr. Edwards exhibited a large number of si^ccies of American Pierinx. 

 Captain Cardew, a short series of Epione advenaria, including a unicolorous 

 specimen from Godalming. Dr. Hodgson, the imagines bred from a brood of 

 Pieris napi from ova laid in May, 1909. Some emerged in July and August, 

 1909, but most of the insects did not appear till the spring of 1910. Mr. Har- 

 rison reported the assembling of 21 c? s of Amphidasys hetularia, 14 of which 

 were v. doubledayaria, at Woodford. 



June 237-d. — The President in the Chair. 



Mr. Ashdown exhibited a specimen of ^Egeria culiciformis and the rare 

 Coleopteron, Anthaxia nitidula from the New Forest in May. Mr. Newman 

 a very long bred series of Ematiirga atomaria, with a large proportion of 

 melanic specimens. Mr. West, specimens of Coleoptera and Hemiptera taken
