incision in the plant cuticle is longitudinal to the leaf and 
takes place rather by separating the plant cells than by cutting 
any through, with the result that it closes up again, and 
makes it impossible on close examination to be certain that 
one sees any trace of the opening by which the egg was 
inserted. 
The photographs are by Mr. A. KE. Toner. The stereoscopic 
figures enable the structures to be seen in high relief. 
VARIATION IN PIERIS NAPI, var. BRYONIZ.—Mr. A, Har- 
rison and Mr. H. Marn exhibited four broods from females of 
Pieris napt, var. bryonix, captured on the Kleine Scheidegg 
Pass, Switzerland, in July 1906. 
20 males. 
Brood A, 16 females. 
24 females.

Brood B. { Ip males. 
Brood C. { 
48 males. 
Brood D. { 59 females, 
The larve pupated at the end of July and beginning of 
August 1906, and the insects emerged between May 2nd and 
June 14th, 1907. 
There was a considerable amount of variation in the females 
of all the broods, but especially was this noticeable in Brood 
B, where some had the ground colour of a decided yellow and 
the black markings well defined, whilst others were uniformly 
grey with the markings almost absent. This grey form 
occurred also in Brood C, but not in Broods A or D. The 
males showed only slight variation, and like the females were 
larger than the English Spring emergence. 
Lycaus EQUEsTRIS, Linn. — Prof. T. Hupson Brare 
exhibited a specimen of this rare bug, which Mrs. Hudson 
Beare found on a flowering umbel on the cliffs at St. Mar- 
garet’s Bay on August 29th last. There are only four previous 
records of its capture in this country: Bath, 1837; Devizes, 
1864; Dover, September 7th, 1886; Sheppey, September 
22nd, 1906. Mr. Saunders is of opinion that it is a doubtful 
native, and is most probably only an occasional visitant.
