YI. 
CONTRIBUTIONS TO THE KNOWLEDGE OF THE ENTOMOLOGI¬ 
CAL FAUNA OF HERTFORDSHIRE. No. 1.—LEPIDOPTERA. 
By John Hartley Durrant, F.EJ.S., Memb. Soc. Ent. de France. 
Read at Watford, 31s£ January and 8th May , 1888. 
During the past year I have devoted some considerable time to 
collecting notices of the occurrence of Lepidoptera in our county. 
I think it will be found that the following compilation contains 
nearly all the references to Hertfordshire. At present I am unable 
to obtain access to other works likely to add to our list, but I hope 
to give a continuation of this paper at no distant date. 
To prevent re-duplication of work I give a list of the serials and 
separate works which I have searched, with the number of species 
mentioned in each as occurring in Hertfordshire.

The arrangement followed is that of Doubleday’s List, and where- 
ever the nomenclature has been altered the original name is given 
in brackets. The species are given under localities with a view of 
obtaining fresh additions to each town by showing residents how 
little is known of their district.

Herts.”—Rev. H. Harpur Crewe.
