NOTES AND OBSERVATIONS.

distinctly gregarious, and an interesting point in this connection was 

 noted. Two batches of ova hatched on different days, but all the 

 larv£D were placed in the same small box. Althougli this mixing had 

 taken place, at the end of twelve hours, two distinct colonies were 

 formed ; and this arrangement was maintained until the second 

 moult was completed. A few days elapsed between the corresponding 

 moult of each colony, indicating the different ages of the same. The 

 colony was always formed on the under surface of the leaf, and care 

 was taken by the larvae to devour the parenchyma but to avoid the 

 production of holes in the pabulum. In the third instar the larvae 

 tend to w^ander further afield and to seek solitary shelter in the curled 

 edges of a leaf. At night they issue further and travel rapidly over 

 the leaves, but always return to the under surface or rolled margins 

 by day. — (Di'-) Beckwith Whitehouse ; 52, Newhall Street,

Cyanikis argiolus and L. arion. — A short time ago small black 

 marks were noticed on some unexpanded ivy buds. On examination 

 these marks proved to be small circular holes, varying from about -^^ in. 

 to yV i'^- ill diameter, the whole of the interior of each bud having been 

 cleaned out. On searching the bush at night (about 8), eight larvae of 

 C. argiolus were found feeding upon the flower-buds, the small heads 

 and necks of the larvae being thrust through an astonishingly small 

 hole. During the daytime no larvae could be found by the closest 

 searching. On beating the bush into a tray at 9 p.m., however, about 

 twenty larvae were taken, varying in length when at rest from 3-% in. 

 to Y^e in. Is this larva exclusively a night feeder ? Since the fore- 

 going notes were written, one C. argiolus larva has eaten two other 

 larvae and four pupae, nothing but the shells of the latter being left. 

 There were originally seven larvae in a roomy glass-bottomed pill-box, 

 and they were well supplied wnth ivy flower-buds ; these buds had, how- 

 ever, apparently been neglected. Does the larva of L. arion during 

 any stage feed upon the larvae of Formica rufa'^ — G. B. Kershaw. 



Eare Coleoptera at Hindhead, Surrey. — I should like to 

 record having taken at Hindhead, amongst other rare beetles, Ontlio- 

 phagus taurus and Monochammus sutor. — A. Richards ; c/o Lady

Lampides BffiTicus IN GUERNSEY. — As I Write (September 19th), 

 L. baticus is still disporting itself in view of my window. There 

 has been a considerable number of this species with us since the 

 beginning of the month. On August 11th I first saw some worn 

 specimens of an earlier bi'ood, probably immigrants, including females, 

 flying round a bush of Colletia arborescens, close to my study window. 

 I was therefore on the look-out for a September display, and have not 

 been disappointed. Though not so common as in the year 1899, it 

 seems to have bred very extensively in the island ; I have taken some 

 forty specimens in my garden, and could have easily taken as many 

 more. I placed two females in a muslin cage, with food-plant, and 

 have got a fair supply of eggs, but hardly expect that I shall bring 

 them to a successful issue at this late time of the year. — F. E. Lowe ;
