ACULEATE-HYMENOPTERA AT TOSTOCK, NEAR 
BURY ST. EDMUND’S. 
By W. H. Tuck. 
Read 81st October, 1899. 
The fine dry season of 1891) was an unusually brilliant one for 
field work, and although I was unable to get out before the end of 
May I added the following to tny list of Aculeate-IIymenoptera : — 
Formica fusca, Linn. I found a small colony on the heath in 
July, and again in September on Bungay Common. 
Lasius alienus, Forst. I took several workers upon the heath 
in July under stones. I believe this species is generally overlooked, 
as it oidy is a little paler than Lasius niger. 
Mutilla rufipes, Ltr. July 8th, two males in bright sunshine on 
a sandy bank. 
Pompilus rufipes, Linn. August 27th, a female on a sandy bank. 
Diodontus tristis, Y. de Lind. July 11th, a female on Cow 
Parsley. 
Cerceris ornata, Fab. August 27th, several on a sandy bank. 
Sphecodes longulus, Y. llag. May 28th, on ground which 
I have worked often before. A female in company with other 
common species. This is a new record for Suffolk. 
Dasypoda hirtipes, Latr. July 9th, a fine male, highly coloured, 
on Dutch Clover. 
Anthophora retusa, Linn. I took a female of this rare Bee on 
the White Nettle, June 1st. 
My list, therefore, now stands : — Ants 12, Fossores 62, Wasps 13, 
Bees 122: total 209; and compares favourably with our county 
list of 282 species, which includes all Kirby’s captures. 
On May 28th I took a male Sphecodes, which Mr. E. Saunders 
and Mr. F. Sladen both agree is S. similis, and no doubt
