(Elgar). At the same time another specimen was secured; both 

 were males. Two days later I captured a female in the same neigh- 

 bourhood. 



Cicendela campestns, which is recorded in ' History of Kent, 

 Insects," as " abundant in sandy places," occurred in great profusion 

 on the chalky paths near Crundale, quite as abundantly as in sandy 

 localities. — H. C. Efflatoun ; Wye, Kent. 



Notes from North Wales. — In Porthtre Castell Bay, about 

 two miles from Ehos Neigr (Anglesey), Sericoris littoralis was fairly 

 common from September 10th to 17th. It is very well protected 

 by its coloration when at rest on the rocks. Between this Bay 

 and Rhos Neigr were a good many plants of Sesile viaritima, some 

 of them covered with larvee of Pieris brassicm (I do not think 

 I have seen the plant previously mentioned as one of its food- 

 plants) ; and all of them swarming with the rather local little 

 beetle Psylliodes marcida. But insects of every kind were extremely 

 scarce. I saw one male Colias editsa at Ehos Neigr ; but the only 

 common butterflies were Pararge inegcera and Chysophaniis phlcsas. 

 Later in the month, in a swamp (about 1000 ft. above sea level) 

 between Capel Curig and Llyn Crafuant, Ambhj'pttUa acanthodactyla 

 w^as swarming; every step put up half a dozen of them, and I had 

 as many as twenty in my net at once. I had never seen it so before. 

 This abundance, however, was confined to one small bog ; in the 

 neighbouring bogs there were only scattered specimens. — A. W.

Gelechia obsoletella.— In the November ' Entomologist ' Mr. 

 J. W. Heslop-Harrison at the end of his notes upon Cecidomyidae, 

 pp. 244-5, states : " It is well to note here that Gelechia obsoletella, 

 an insect not on record for Durham, occurs in practically the same 

 patch of plants." This statement, " an insect not on record for 

 Durham," is incorrect, as a reference to the Lepidoptera of Northum- 

 berland and Durham, vol. ii, p. 160, will satisfy Mr. Harrison. Under 

 obsoletella, after Robson's remarks upon the species he concludes : 

 " Mr. Gardner has met with the true obsoletella at Grantham his 

 specimens having been verified by Mr. Bankes." I may state that 

 my friend Mr. J. W. Gorder, of Sunderland, has quite recently bred 

 obsoletella from larvae feeding in the stems of Clienopodium collected 

 on the sea banks near Sunderland— J. Gardner ; Laurel Lodge, 

 Hart, West Hartlepool. 



Libellula depressa. L. — There were several specimens of this 

 species, in both sex, hovering over small ponds near Yate,West Gloster, 

 on June 15th, 1917.— Ida M. Eoper ; 4, Woodfield Eoad, Eedland,

Apples attacked by Larv^ of Porthesia SLAiins.—Like Mr. 

 Adkin, I noticed larvae of Porthesia similis attacking apples this 

 year in the garden of a friend at Bockhampton as early as June 13th. 

 Although I looked carefully I could not see that any fruit was 

 attacked in my garden, where the larvae were also plentiful on the 

 trees. The larvte, of course, at that season were almost full-fed and 

 single, and had eacli bored a small rounded cavity in the fruit. I
