was therefore agreed that as previously a publishing committee should 
be formed to deal with the matter. 
Wimbledon lepidoptera. —Mr. May exhibited Triphaena subseqna 
(comes), two banded forms, and one with the hindwings sufl'used ; a 
specimen each of Ayrochola pistacina and A. litura, with dark bands 
across the primaries ; an example of Glaea vaccinii of a peculiar grey 
tint, somewhat corresponding with a form known to occur in Wales. 
Exotic Spiiingid^:. —Mr. Kaye, a number of Sphingidae, which 
included Wallengrenia aper from Columbia, Ambulyx substriyilis with a 
tine dark var. from Assam, with Anyonyx testacea (ella) from the same 
locality. Polyptichus pusillus from Natal, and Pseudosphinx incisa and 
Ambulyx palmeri from Rio Janeiro. 
Folkestone lepidoptera.— Mr. Pickett, Ayrotis tntici taken at 
sugar in July, 1899. Cosmotriche potatoria bred from larvae found at 
Whitsuntide, 1899, also Smerinthus ocellatus bred from a Tottenham 
larva. 
Agrotids. —Mr. Prout, fine series of A. tritici, A. obelisca, A. 
aquilina, A. niyricans and others ; also A. tntici from Berlin, and 
A. aquilina and A. obelisca from Vienna; A. niyricans from 
Gratz, and A. crassa from Vienna. Mr. Dadd, many species of the 
genus Ayrotis. Of the European, A. niyricans, A. perpoleta, A. tritici 
and villeripennis were shown ; of the American, A. subyothica, A. 
heriiis, A. introjevens and A. quadridentata were exhibited. 
Discussion on the Agrotis tritici group.— The President said that 
the first question to be asked was, how many species have we? A. 
cursona he thought, was one of the most difficult species. He 
personally had found that generally this insect had narrower forewings, 
which character might be of use for separating it. As to whether this 
species occurred on the Kentish coast there was much doubt. On the 
Lancashire littoral it was, however, easily separated from A. tritici, the 
coloration there being very distinct. A paragraph was read from 
British Noctuae and their Varieties, where Mr. Tutt gives it as his 
opinion that only parallel forms to A. cursoria, of A. tritici exist on 
the Kent coast and that true cursoria is unrepresented. The same also 
applied to A. obelisca. Mr. Dadd followed, and said that A. cursona 
was generally more sandy-coloured than A. tritici. He believed that 
local variation w r as strong, but that in some localities all forms were to 
be found together. Several of the North American species v r ere 
discussed, and the remarks of Speyer concerning A. aquilina were 
introduced. Speyer affirming that the few A. aquilina from the south 
of France are different from A. tritici, the antenme being longer and 
more pectinated. Mr. Kaye asked if A. aquilina had its status solely 
on the characters of the perfect insect, to which the answer was in the 
affirmative. The Rev. C. R. N. Burrows, who was not present, sub¬ 
mitted that what we call A. aquilina is really only a marsh form of A. 
tritici, and that while A. aquilina inhabits the marshes, A. tritici 
frequents downs and such-like dry situations, and that the tw r o are 
never transposed in habitat. 
Feb. 6th, 1900. —Exotic Spiiingid^r.— Mr. Dadd exhibited two boxes 
of foreign Sphinyidae, and Mr. Bacot also showed some exotic species of 
this family. The specimens included Thyreus abbottii, Choerocampa 
schenkii, C. porcellus, Elibia doliclius, Deilephila lineata and D. licornica, 
with many others.
