tins country. Tliey are about one-third smaller than the normal queens of fusca, 

 and differ also in having Iho abdomen pubescent like the workers. In all these 

 nests only microgyne insects were to be seen, and 1 do not know to what cause the 

 production of these microgynes can be ascribed ; but it may be worth mentioning 

 that in one nest an example of Atemeles emarginatus was found. The first nest 

 which I found was a very small one, containing only 9 s and ? s, with some larvse 

 and pupoe. The other two nests, however, were crowded with examples of all sexes, 

 as well as larvse. The <? s obtained from these did not differ in the least from tiie 

 normal type /wsca. — G. Arnold, University, Liverpool : November I5th, 1909. 



Aculeate Hymenopter a in the London District. —GoWecting in two localities of the 

 above district, Heme Hill and Wimbledon Common, in sucli fitful sunshine as there 

 was during the past summer, a total of 110 species of AcuJeata was met with. 

 Among those worth mentioning, the localities being possibly so far unrecorded for 

 them, were two (? c? of Crabro gonaqer, captured in the garden here (Ilerne Hill), 

 also a (? of C. podagricus and five C. varies, two curious dark varieties of the c? 

 with the normal type. In a small hole in one of the wooden posts enclosing the 

 railway I found in June a ^ Sapt/ga quinquepunctata. 



I think the most productive parts of Wimbledon Common are to be found, 

 rouglily speaking, on the golf links ; with the exception of Erica, bramble and 

 hawthorn blooms in their seasons, it is practically destitute of flowers, so attention 

 was chiefly paid to such pits and more or less bare patches of sand where the 

 insects breed ; a large one of the latter at the windmill end of the links was all the 

 season very full of the burrows of a number of species. 



Among the 17 species of Andrena found were A. clarkella, a colony of A. 

 cineraria, confining themselves to a space of a few feet, both sexes of A. angustior, 

 fairly common, and A. similis and A. nana in May ; of this last I took a modified 

 9 having three Stylops under the 4th abdominal segment. 



Two A. argentata g <? were taken on Erica in August and a pair of Nomada 

 jacobieie also. I believe too that Wimbledon is an unrecorded locality for Sphecodes 

 longulus, of which I got one ? . Odd ? ? of Diodontus luperus, Gorytes tumidus 

 and a (? of Nysson dimidiatus were also obtained and several specimens of both 

 sexes of Crabro panzeri. 



In two places on the Common, one being the bare sandy patch before referred 

 to, Mimeaa shuckardi and M. bicolor were fairly plentiful, as was also Myrmosa 

 melanocephala^ 9 , more abundant after the sun began to lose power about 4 p.m., 

 only one $ was caught. In both places the Myrmosa confined themselves to a 

 small area, with them I took two 9 9 of Methoca ichneamonides about 11 a.m., on 

 separate days, one of these as compared with the other being very small and dark, 

 almost black. 



I found Halictus punciatissimus in the garden here, and also at Wimbledon. 

 I am indebted to Mr. E. Saunders for much kind help with the identifications,
