LEPIDOPTERA AT HITCHIN AND KNEB WORTH. 
APPENDIX. 
Notes on Mr. Durrani’s List of Lepidoptera. 
By A. F. Grifeith, M.A. 
Mr. Durrant lias kindly supplied me with information as to a 
few species included in the above lists which he has not obtained 
himself. 
Sesia formiciformis. —Two specimens taken by Mr. Christian at 
Norton near Baldock. 
Toxocampa pastinum. —Caught at Kneb worth by Mr. Benjamin 
Brown, formerly of Deard’s End Farm. 
Calligenia miniata. —Caught at Knebworth, also by Mr. Benjamin 
Brown. 
Melitcea Artemis. —Taken at Kneb worth Wood, by Mr. B. 
Christian, two or three years ago. 
The first two of these species might perhaps be expected to occur 
here, as they are found in the adjoining county of Cambridge, in 
the fens. Knowing, however, as I do, how easily any one forgets 
the exact locality of insects placed in his collection, unless a note 
of it is made at the time, I should feel disposed to ask for further 
information as to them before finally admitting them as distinguished 
members of our County List. If any member of our Society should 
be in the neighbourhood of Baldock or Knebworth about the middle 
or end of June, and would examine the dead twigs of sallow or 
osier for the pupa of S. formiciformis, which is concealed in a burrow 
within, and would also, just before dark, watch the marshy spots 
where Vicia Cracca grows, for the large pale T. pastinum , he will 
very possibly have the satisfaction of confirming these two very 
interesting additions to our list. 
The last two of these species, with Nrastria fuscula, are new to 
our list, and are also very interesting additions, and this prolific 
neighbourhood is certainly worthy of a careful examination. 
I may add that lists, including a considerable number of species 
new to our County records, have been received from Mr. F. J. H. 
Jenkinson (of insects taken in the neighbourhood of Berkhamsted), 
Mr. B. Piffard of Hemel Hempstead, Mr. A. E. Gibbs and Mr. A. 
Lewis of St. Albans, and Mr. Horley of Hoddesdon. A tabulated 
list of these will, it is hoped, shortly appear in our ‘ Transactions/ 
and I hope before then to receive further contributions.
