Mo. Maf?., Series IT, i, 193 ; xv, 254). All three spots lie within a radius of about 

 one-sixtli of a mile from a point taken between the two that are furthest apart, and 

 I hope the day may come when I shall succeed in discovering the head-quarters of 

 the species— if, indeed, it has any more definite head-qnarters in this district— and 

 get some clue as to its food -plant. — Id. 



Retarded emergence of Leiocampa dictxoides. — I see that Mr. Eustace Bankes 

 in his note on the emergence of Leiocampa dictxoides considers July 14th 

 a remarkably late date. In this district the insect is fairly common, and I have 

 bred and taken some hundreds during the last twenty years. I find that the bulk 

 of emergences and captures occurred in the first fortnight in July, although I have 

 taken it as late as September 3rd, and as early as April 30th. I took one last year 

 on August 12th. If kept under as natural conditions as possible and not forced 

 they almost invariably emerge during the first three weeks in July. There is, I am 

 practically certain, no second brood here, as T have on several occasions obtained 

 early larvae, which pupated about the middle of July and did not emerge until 

 the next year. — Richard Feeer, Rugeley : Fehruary^ 1906. 



Rhyacophila munda, McL., and Halesus guttatipennis, McL., in Scotland. — In a 

 small lot of Trichoptera recently submitted to me by my friend Mr. William Evans, 

 there was a Rhyacophila which at once aroused my curiosity. It proved to be 

 Rhyacophila munda, McL., just about the last species that I should have looked for 

 in the east of Scotland, having regard to its previously recorded distribution. It 

 was discovered by McLachlan in 1861 in South Devon, and in 1863 he again found 

 it in North Wales. It also occurs at the Exmoor streams. For a long time it 

 remained in the position of a species apparently peculiar to our Islands, but this 

 was hardly likely to be the case, and its discovery by M. Eene Martin in the De- 

 partment of Indre, I'rance, put an end to its claims to be considered exclusively 

 British (Ent. Mo. Mag., vol. xxiv, p. 262, 1888). Further, it was taken by Mr. 

 Theobald in the Island of Sark in 1890 (Ent. Mo. Mag., vol. xxviii, p. 74, 1892). 

 These records all seem to point to a southern and western distribution, and its 

 occurrence in the east of Scotland is certainly as unexpected as it is interesting. 

 The precise locality where the single ^ was taken is Cowie's Linn., a deep ravine 

 near Eddleston, Peeblesshire, and the date September 24th, 1904. 



An almost equally interesting capture has been made by Mr. Evans this 

 autumn. While collecting at Cobbinshaw Eeservoir on November 8th he met with 

 a Trichopteron in considerable numbers, and secured over a dozen specimens. The 

 day was cold but sunny, and about noon the insects were taking short flights, rising 

 from and alighting on the stones and grass at the sides of the loch. The species, 

 as Mr. Evans had supposed, is Halesus guttatipennis, McL. 



This insect has a somewhat curious history. It was described by McLachlan 

 in 1865 from a single <? example taken somewhere in the North of England. Stein 

 applied the name to a different species taken by him in Silesia. Mr. McLachlan, 

 with an undue want of confidence in his original description, and not being able to 

 re-examine the type, accepted in his Monograph the Silesian insect as guttatipennis, 

 while the true insect, which had become known from Switzerland, "was called mu-
