The discovery of Chopardina importata, which possibly also breeds 

 in hot-houses, since a half -grown larva has been captured with the type, 

 shows that additions to the fauna of English greenhouses may still be 

 expected. It is possible, also, that specimens of Chopardina are 

 commonly mistaken for Tachycines, but the above-given characters 

 render their separation easy. It must be, however, borne in mind that 

 other species of both these genera, as well as additional genera, may 

 occiu-, and the author will be glad to help with identitication of 

 specimens*. The S of Chopardina also remains to be discovered, and it 

 is worth while to look for it. Moreover, it must not be forgotten that 

 Tachycines is an insect which does not like daylight, and Chopardina 

 possibly shares in this aversion ; they must be looked for in the darker 

 corners of greenhouses, where they are hiding for the day, being active 

 in the night.

A black variety of Papilio machaon in Norfolk. — The following- article, 

 under the heading of " An all-black butterfly," appeared in our daily 

 press on August 11th ;— "Mr. J. P. Lloyd, of St. Giles's Vicarage, Norwich, 

 informs The Daily Mail that he has captured a black specimen of Fayilio 

 viachaon, the swallow-tail butterfly, on the Norfolk Broads. lie adds: I 

 believe this is the only black specimen in existence. The swallow-tail is 

 practically confined in this country to the fens of Cambridges-hire find the 

 broads of Norfolk, especially the neighbourhoods of Wicken I'en and Hick- 

 ling Broad." This insect is doubtless referable to ab. viyer Heyue-If iihl 

 (1892-95) of Staudinger and Eebel's " Catalog," 1901.— Eds.: Avymt 192]. 



Heptaulacus villosus Gyll. and other Coleoptera in North Yorkshire. — I am 

 much pleased to be able to record the recent occurrence of Heptaulacus lillo&us 

 Gjll. in Yorkshire. I found a single specimen of this rare species on the toast 

 sandhills at Redcar on June 24th. StenusfoveicoUisKv. occurred in Sphaymnn on 

 the moor above Reeth, Upper Swaedalle, in May last, and this year the same 

 species turned up on the moor near Ingleby Greenhow in the Cleveland district 

 at the same elevation (1400 ft.). Last September, Stenus fuscicornis Er. was 

 taken in Sphaynum at Brignall Banks, Barnard Castle : a northern locality for 

 this south country insect, not previously met with in Yorkshire. In a moorland 

 wood at Kildale in July, Hajmlaraea pyytnaea Gyll., also rare in the north, and 

 Epuraeajlorea Er. were taken on mountain-ash, with Tetratoma ancora V. 

 from the Scotch hrs growing close by. Choleva morio F. dropped from a dead 

 grouse found lying on the adjacent moor. The cosmopolitan beetle, I'tinus 

 tectus Boield. has recently been found in some numbers in the bathroom of a 

 dwelhng-house at Middlesbrough. I am indebted to Commander J. J. Walker 

 for his kindness in identifying most of the above-mentioned inescts. — M. 

 Lawson Thompson, 40 Gosford Street, Middlesbrough : August 1921.
