THE entomologist’s RECORD. 
Aneurism. — My only experience of saccular distention of wings was 
in the case of Nofiagria typhcB. Nearly all of a series bred in 1889 
were thus affected ; but, as I found that by pricking the distention 
they soon became all right, I took no further notice of it. — E. W. 
Brown, Shorncliffe Camp. May^ 1891. 
Variation. 
Folia chi and its Varieties. — You ask me for information 
concerning the var. olivacea in the Castle Eden district. I regret I 
am unable to say anything about it as I never took anything but the 
type there, and very few of that. Thirty years ago I took v. olivacea 
here in some numbers, along with the type, but it seems to have dis- 
appeared for I have seen neither for quite twenty years. Olivacea 
is comparatively common about Newcastle-on-Tyne, whence I obtained 
all the specimens I have had of recent years. It passes the winter 
in the egg state, which are of the usual Noctua form, like a tiny limpet 
shell, and deposited so that one overlaps the other. It is an easy 
species to rear, and a bred olivacea is something very different to the 
faded specimens captured, being much darker and not so green. The 
first I ever bred appeared to be something I did not know, and thoughts 
of a new species came into my head, but quickly proved vain thoughts. 
In the west of the county of Durham — perhaps I should say the south- 
west — the type occurs commonly but I have no knowledge of olivacea 
occurring there. If the species occurs in the north-west, I should 
expect it to be olivacea rather than the type. In the Cleveland district 
of Yorkshire the type form is also very common, and may be taken in 
any number at rest on the stone walls that form boundaries on the 
moors. In West Yorkshire another form occurs, distinct enough to 
have a varietal name. Instead of the pure white of the type, it has the 
ground much suffused with grey. It is scarcely so dark as captured 
olivacea^ and is entirely without the greenish hue of that variety. 
Suffusa would be an appropriate name for it. I know little of the 
species from other places. The few Scotch specimens I have seen, 
all have the pure white ground of the type. I have no acquaintance 
with it from the south of England, nor from Ireland. — John E. Robson, 
Hartlepool. 
Variety of Argynnis paphia. — The form of A. paphia with pale 
spots on the wings is, I believe, a well-recognised variety of the male 
in the New Forest, several were taken there the same year as mine. 
The spots vary very much ; sometimes the white spots are present on 
all the wings as in my specimen, sometimes on only two of them ; in 
some specimens, also, the spots are much more distinct than in others. 
I believe mine to be a fair type of the variety with regard to the 
distinctness of the white markings. It would be interesting to have 
the opinion of several entomologists, as to the cause of these 
markings. — E. C. Dobree Fox. Aprils 1891. 
Varieties of Apamea basilinea and Noctua rubi. — On May 
28th, I took a very nice var. of Apa??iea basilinea^ either imicolor or 
nebulosa, but whichever it may be, it is quite distinct from any that I 
have ever taken before. At the same time I got some good variations 
of Noctua rubi, varying from quite a light reddish colour to dark brown
