ENTOMOLOGICAL NOTES FOR 1902.

The weather all the collecting season was very broken and varied, 
but I managed to get through a good lot of field work, my chief 
occupation being the somewhat neglected groups of water insects. 
Starting with the Aculeate-Hymenoptera as usual, I record a new 
Wasp for Britain, Odynerus bifasciatus, Linn. I took specimens of 
both sexes as long back as June 1895 and 1897, but Mr. Edward 
Saunders has only recently identified them, as they were mixed up 
with a large colony of Odynerus sinuatus, to which they bear 
a striking resemblance. This brings the list of Suffolk Wasps to 17. 
At Cromer, in August, I found the large Ant, Formica fusca in 
plenty, together with the winged sexes of another, Lasius umbratus, 
which does not appear in Mr. Bridgman’s list. The next day, 
August 16th, being very fine and sunny, I took two females of 
Tiphia femorata upon Wild Carrot ( Daucus carat a) in the same 
locality that the late F. Smith found it twenty-live years ago. 
Close to the old Station, I took a scarce Bee, Andrena nigriceps, 
together with its parasite, Nomada jacobaeae, which were flying 
around its burrows and entering them. At Plumstead Lake, on 
June 7th, I took on Hawthorn bloom a male Bee, new to Norfolk, 
Andrena ambigua, which I have twice before taken at Tostock. 
I added ten Beetles to the list for Suffolk, published by 
Claude Morley in 1899; of these Homalota ravilla and Quedius 
obliteratus were both in an old nest of Vespa vulgaris, which 
I opened March 13th. I understand that the obscure genus of 
“Quedius” in Coleoptera still needs much revision.
