NOTE ON THE ABOVE. 



The occurrence of Diodontus friesei, Kohl, in the Channel 

 Islands is o£ great interest. I took a few in Jersey, hut did not 

 record it, as at the time I thought it was only minufus ; the ^ may 

 be easily known from that species by the form o£ the intermediate 

 metatarsi — in miniitus these are much produced and widened towards 

 the apex, in friesei they are bent but hardly widened ; like miniitus it 

 has the mandibles yellow. Hitherto friesei has only been recorded 

 as a South European and Mediterranean species. 



The capture of Coelioxys afra is I think still more interesting. 

 In this country I have sought in vain for any of the small red tailed 

 Coelioxys associating with MegncMle argentata. I was much pleased 

 to find Coelioxys hrevis with 31. argentata in Jersey, and now C. afra 

 turns up with it in Guernsey. 



It is curious that in each island 3Iegachile argentata should have 

 a different species to associate with it ; possibly, however, both of 

 them may yet be found in the two islands. These little species belong to 

 a group of which we have no exponents in Britain, and which is peculiar 

 in having the white bands of the abdomen formed of scale-like hairs. 

 They are both common in South Europe ; C. hrevis has occurred in 

 Central Europe, but I have always looked upon C. afra as quite a 

 southern form. — E. Saundeks. 



HALICTUS BREVICORNIS, Scheank, 

 AN ADDITION TO THE LIST OF BRITISH HYMENOPTERA. 



BY EDWAED SAUNDERS, F.R.S. 



I met with both sexes of this insect some years ago somewhat 

 plentifully in Jersey, and since then have kept a careful look out for 

 brevicornis in this country. It was not, however, till last summer, 

 when collecting at Southbourne, near Christchurch, Hants, that I suc- 

 ceeded in meeting with the species. On the wing it so closely resembles 

 villosulus, K., in the ? sex (the only one I wos able to get) that it might 

 be very easily passed over, and I feel sure that had I not made it a rule, 

 since my visit to Jersey, to examine suspected villosulus pretty care- 

 fully before rejecting it, I should have failed to recognise brevicornis. 

 The chief distinguishing character of the ? which appeals to one is the greyer
