lieinarks oii L'oenonympha Typhon and C. Davus. — Some time ago I sent speci- 

 mens of C. Typhon to Prof. Hering, who informs me they are the var. Rothliehii of 

 German writers, and that similar examples had been taken near Hamburgh. 0. 

 Typhon is not rare in Argyleshire (where I have found it scarcely above the sea- 

 level), and all that I have seen differ from C. Davus in having the white streak on 

 the u. s., f. w. far more oblique and directed towards the anal angle ; while in all the 

 specimens of C. Davus I have seen it is directed towards the inner margin, at some 

 distance from the angle. Typical C. Davus, from Germany, more resemble Scotch 

 than English specimens. — A. Wilson, Edinburgh, January, 1865. 



Note on the manner in which the females of the genus Leuctra carry their eggs. — 

 In the autumn of 1862, when entomologizing along the banks of one of the impetuous 

 streams of south Devon, my attention was attracted by one of the small PerZidce, which 

 when Hying, seemed to have the abdomen of a pale yellowish colour. On catching 

 this, I found that it was a female of Leuctra geniculata, of Stephens, and that the 

 apparent paleness of the abdomen was owing to a mass of eggs which the insect 

 carried. In Leuctra the last abdominal segment is curved upwards, and the mass, 

 composed of many hundreds of small eggs, extended from the up-curved last 

 segment to near the base of the posterior wings, along all the dorsal surface of the 

 abdomen. I have since repeatedly captured females of this species, carrying their 

 eggs in a similar manner, and have remarked a like habit in the females of a 

 smaller species, L. fusciventris, of Stephens. I have in my collection females with 

 the mass still attached in sitH. 



This interesting fact is not mentioned by previous authors as far as I know 

 but it has long been noticed that the females of the large species of Perla carry 

 their eggs about with them after being extruded, in the form of a little rounded 

 mass, and the females of the Phryganidce do the same, until a fitting time or opportu- 

 nity arrives for their deposition. In the case of these latter insects the eggs are enve- 

 loped in a jelly-like substance, and it has struck me that they may carry them until 

 this secretion is sufficiently hardened to resist the immediate action of the water. —

Notes on Nepticulee at York. — N. atricapitella. — I have found the larva of this 

 species making slender galleries in the leaves of the oak. Cocoon reddish. 



N. pygmceella. — In whitethorn. Larva yellowish. Cocoon brown. Plentiful. 



N. pomella,. — I have met with this species from October to December, chiefly 

 in the leaves hanging from the lower branches of the apple-tree, and very gre- 

 garious in its habits. I have found a leaf with as many as nine of the orange- 

 coloured larvae in it. Cocoon of a rich brown. The imago, which makes its 

 appearance in the latter part of June, or the beginning of July, flies at sunrise ; 

 and is to be found on the trunks of trees during the day. So far as my observation 

 goes, I have not found this species double brooded. 



N. oxyacanthella. — The larvae of this species, which are rather plentiful, are of 

 a bright green colour and mine in whitethorn. I have also found them in the wild 

 apple. The cocoon is purplish-brown. 



N. anumaldla. — I'leutifiil in wild rose ; hii-va yellow.
