FIELD NOTES. 

 ENTOMOLOGY. 



Cicindela campestris (L.) in Derbyshire. — We read with 

 ,s;reat interest Mr. J. M. Brown's note on the occurrence of 

 Cicindela campestris in Derbyshire. We noticed the insect in 

 August of this year (1918) on a saiidy, heather-clad hill-side 

 at Cathole about three miles west of Chesterfield (N. E. Derby- 

 shire). — E. and H. Drabble. 



Gonepteryx rhamni at Louth. — Two Brimstone Butter- 

 flies, usually uncommon in the Louth district, were seen in 

 the Kenwick area (2| miles from Louth) on the 3rd September. 

 A local problem with regard to this species is that no food 

 plant (either R. caiharticus or frangula) is known to occur 

 there, and locally, we suspect that the spindle-tree {Euonyntus 

 europacus), M^hich occurs abundantly in that area, may be the 

 food plant. Can any of your readers give any confirmation 

 of this surmise ? — J. Larder, Louth. 



Sciaphila sinuana in Yorkshire. — Last August, my son 

 Rosse and I took one specimen of Sciaphila sinuana in Bingley 

 Wood, which is a rare and local insect in Yorkshire, having only 

 recently been added to our county list. In addition to this 

 district it has been recorded from Doncaster. — E. P. Butter- 

 Field. 



[Sciaphila sinuana has proved to be common in the county, 

 now that we know how to find its larvae freely in the flowers of 

 Scilla nutans, the common bluebell. It has already been re- 

 corded from the Huddersfield district, where it is plentiful. — 

 G.T.P.] 



Plesiodema pinetellum Zett. in Northumberland. — I beat 

 a pair of this Scotch insect from Scots Fir in a large wood 

 bordering the Bellingham Road a mile or so north of Wark. 

 Several species of Psallus were common at the same time, and 

 Plesiodema might be passed over as a small example of one of 

 these, if not beaten from its true host-plant. The only other 

 record for England for this species is apparently from Cumber- 

 land by Mr. H. Britten {Ent. Mo. Mag., 1916, p. 279). Mr. 

 E. A. Butler kindly identified my specimens. — Jas. Murray, 2 

 Balfour Road, Carlisle. 



Polyommatus phlaeas in Yorkshire. — In connexion with 

 Mr. Butterfield's note on the distribution of Polyommatus 

 phlaeas, this species was abundant in a rough field at Shelley, 

 Huddersfield, in May last. When I first resided in the district 

 ten years ago, I did not meet with this insect. About 19 10 

 one or two were seen and it was never entirely absent, but 

 always uncommon, till 1915, when circumstances transferred 

 my observations to the other side of the Channel. Probably 

 this has been an unusually good ^^ear for the species, which has
