Rare Corteorrera at St. Marcaret’s Bay.—Professor T, 
Hupson Beare also showed specimens of Hypera tigrina, 
Boh., taken in some numbers on the wild carrot at the foot 
of the cliffs at St. Margaret’s Bay, between August 25th and 
September 5th last ; he was unable to find a single specimen 
on the numerous wild carrot plants growing on the top of the 
cliff. This is a very local insect, and there are but few 
records of its occurrence; it seems to be confined to the 
extreme §8.E. corner of England. 
He also showed specimens of Apion semivittatum, Gyll., 
taken during the same period at St. Margaret’s Bay off plants 
of Mercurialis annua. This species was found in abundance 
more than sixty years ago by Mr. Walton near the Tivoli 
Gardens, Margate; no further specimens were taken in this 
country until 1905, when Messrs. Chitty and Tomlin swept up 
one specimen on the Deal sandhills, and this year, in June, 
Mr. Bryant also swept a specimen in the same locality. 
Mercurialis annua is a garden weed which grows freely in 
many localities in the south-east of England ; it seems to be 
very fond of old potato patches ; the plants in such a habitat 
did not, as a rule, produce the beetle, which was found more 
freely on plants growing in uncultivated spots, hedge-sides, 
etc. Mr. Donisthorpe, who, during the same period, took 
the insect freely off its food plant, at Deal, had the same 
experience. He was able to confirm the statement that the 
larva is an internal feeder, for, on cutting open a stem of a 
vigorous plant showing by knots the presence of the larve, he 
discovered a pupa which was imbedded in a kind of cell; this 
pupa eventually hatched out. 
TRANSITION BETWEEN My.oruris cHLoris, Fasr., anp M. 
AGATHINA, Cram.—Dr. F. A. Dixry exhibited typical speci- 
_mens of the African Pierines Mylothris chloris, Fabr., and JM, 
ayathina, Cram. ; together with a long series of forms, transi- 
tional between the two, from the neighbourhood of the Victoria 
Nyanza. 
He remarked that he had previously called attention to the 
fact that the West-African J/. chloris and the East- and South- 
African M. agathina, which had always been looked upon as 
distinct species, intergraded with one another in the region of
