NOTES ON COLLECTING. ae 
Both at Guildford and at Bourton-on-the- Water, in the Cotswolds, 
I saw several pairs of Zygaena filipendulae on grass stems, the 3 
always being below the ?, and tried to induce them to fly, but in 
vain; failing in this I threw them up into the air, to see which would 
carry the other when compelled to fly. Owing doubtless to the weight 
of their bodies they were unable to fly more than enough to guide their 
descent and prevent themselves from falling; when only thrown a short 
distance it was invariably the g that spread his wings and guided the 
descent, but if thrown to a greater height the ? also spread her wings 
and helped to act as a parachute. I tried the experiment a good many 
times but always with the same result. close WuerEter, BT,

VaRIATION IN CoccINELLIDAE.—Mpilachna corrupta, Mulsant, which 
abounds at Boulder, Colorado, is one of the comparatively few plant- 
feeding Coccinellids, and is extremely destructive to beans of the 
genus Phaseolus. It is very constant in its elytral markings, with 
eight spots on each elytron. Ihave not found the variety juwncta, 
Johnson, which has the apical spots confluent. There is, however, at 
least, in the second generation, a distinct-looking variety with the 
ground-colour deep brown instead of yellowish, with a distinct metallic 
coppery lustre on the elytra. It may be called var. cuprea, n. var.—

LiMEnITIS sIBILLA IN SurREy.—Mr. P. A. H. Muschamp, in the 
July number of the Record asks if there are other records of this 
species for Surrey. Last summer (1917) I was in hospital at Holm- 
wood, near Dorking, and on July 17th I saw a single specimen in the 
woods between Holmwood and Coldharbour. I have also seen the 
species in several woods in Sussex.—(Lieut.) Harotp 8. Witiiams, 
Victoria Barracks, Belfast. July 80th, 1918. 
SUBSTITUTES FOR NATURAL FOOD oF PyRAMEIS caRDUI, ETc.—I found 
the larvee of Pyrametis cardui at Cibali, Catania, Sicily, enclosed in 
webs on thistle leaves. As I could nof get thistles often enough, the 
larvee were practically reared on lettuce leaves. It is very strange how 
almost any caterpillar will eat lettuce when one cannot get their proper 
food. I had about six of these larvee in a box, and on one occasion 
when they were short of food I found that they started eating one 
another. In my garden—where I grow vegetables and flowers—I 
have left a fennel plant to go to seed (the root is eaten here as we do 
celery in England). On it the other day I found the Lee) of Papilio 
machaon. —Perrcy Sxetcutey, Catania, Sicily. 
A GynanpromorH or AGRIADES Said *< Or August 8rd last, whilst 
collecting with my wife on the downs in the Blandford district, I had 
the good fortune to take a perfectly halved gynandromorphous Agriades 
coridon, the left wings being male, and slightly smaller, and the right 
side female. The colouring of the body and head on each side follows 
the wing. The insect is in perfect condition and was apparently in its 
first flight. 
Tutt, in his British Lepidoptera, records three similar specimens,
