202 THE ENTOMOLOGIST. 



tions of the species in the Cotswolds, for which I propose names 

 as follows : — 



(1) Ab. pseudo-alcon. — Aberration of male with the wings dn the 

 upper surface unspotted, and formerly erroneously considered to be 

 the true alcon of Continental Europe. Eare. 



(2) Ab. imperialis. — Aberration of female. An exceedingly fine 

 form, generally of a brilliant blue, with the black spots on the upper 

 surface of the anterior wings elongated into pearl-shaped streaks, 

 giving them the appearance of a diadem or crown. Not uncommon 

 here. This is of frequent occurrence in the South of France. 



(3) Ab. muUo-maculata. — Aberration of male and female with the 

 posterior wings on the upper side possessing a corresponding series 

 of spots as on the anterior wings, though much smaller and more or 

 less indistinct. This is almost as plentiful as the typical form, which 

 is without them. 



(4) Ab. marginata. — Aberration of male and female with all the 

 wings possessing very broad black margins. Not uncommon. 



(5) Ah. cotswoldensis. — Ahevva.tior). of male and female with all 

 the wings more or less thickly sprinkled with black scales, giving it 

 a very dusky or melanic appearance, constituting an approach to the 

 alpine var. obsciira of Professor Christ. Scarce. 



(6) Ab. pallida. — Aberration of male and female of a pale washed- 

 out appearance. Not uncommon. • 



(7) Ab. occidentalis. — Aberration of male and female. Very dwarf 

 undersized specimens, some not larger than L. agon. Of fairly 

 frequent occurrence. 



(8) Ab. oolitica. — Aberration of male and female of under side 

 exhibiting fewer spots than in the typical form, some of them 

 coalescing. Eare. — Champion le Chamberlain ; Cheltenham. 



Neuropteea from the South op Feance.^ — In January last Dr. 

 T. A. Chapman gave me a small collection of Neuroptera taken by 

 him at Gavarnie from the 9th till the 30th of July, 1907, whose names 

 appear below. Mr. K. J. Morton was good enough to assist me with 

 the identification of some of the specimens : — 



Odonata. — Gordulegaster annulatus, -"C bidentatus, '''-Platycnemis 

 latipes, PyrrJiosoma nympJmla, Agrion mercuriale. 



Perlidia. — Perla maxima, Ghloroperla grammatica, Nemoura sp., 

 Amphinevioura sp. With the last three there must be unfortunately 

 a little doubt as regards identification when males are not present. 



Planipennia. — ■■'■Ascalaphus longicornis, *^. coccajus (a consider- 

 able number, all but one being females), -'^Panorpa mcridionalis, 

 ■■'Megalomus tortricoides , M. hirtus. 



Trichoptera. — Ecclisopteryx guttulata, -''-Drusus monticola (or 

 nearly allied to it), '"D. rectus, "^Sericostoma pyrenaicum, Hydropsyche 

 pelkicidula, Philopotamus viontanus, ■•'Rhyacophila tristis. 



With these were also two insects taken at Cauterets from the 1st 

 till the 8th of July — one Ghloroperla grammatica, which is subject to 

 the same doubt as the specimen above ; and one female Ascalaphus 

 coccajus. The insects with which an asterisk ('•') is placed are non- 

 British species. — W. J. Lucas ; Kingston-on-Thames.
