116 [October, 



On the same poplar I saw a few Phytocoris distinctus taking long courses with 

 the utmost rapidity up the trunk, ultimately ending their exercise in a crevice of the 

 bark, into which they squatted closely, and by their black colour were difficult to 

 distinguish from their " environment," as the covert would be termed in the modern 

 phraseology. The species was first detected at Blackheath on Populus alha, and 

 this tree seems to be its special habitat. Fh. tilia:, found resting on the dark bark of 

 the same tree, was by its light colour rendered conspicuous. — J. W. Douglas, 8, 

 Beaufort Gardens, Lewisham : Septemher 10th, 1885. 



Hymenoptera at Chohham in August. — Although I have not found this year a 

 good one for Hymenoptera on the whole, still I was fortunate enough in one morn- 

 ing's collecting at Chobham to secure several species worth recording. They were 

 all taken on the common, near what is known as Burrow Hill. 



Myrmica sulcinodis, Nyl., 1 $ running on the ground ; tliis is the only time 

 that I have met with the ? of this species. 



Methoca ichneiimonides, Latr., 1 ? running on the ground. 



Pompilus chalyheatus, Schiodte, ? on a bare sandy spot. 



Mimesa hicolor, Jur., rather commonly, together with the rarer M. unicolor, 

 Y. de L., but I only obtained females of either species. Both of the black species 

 have now occurred at Chobham, and although so very much ahke, are abundantly 

 distinct structurally ; the raised lines on the under-side of the 9th and following 

 joint of the antennae in the ^ , and the shining dorsal apical segment of the abdomen 

 with its strong lateral carin£e in the ? , at once distinguishing Dahlbomi, Wesm., 

 from unicolor, V. de L. 



Crahro scutellatus, Schev. — Of this rare species I took three females flying 

 about over the sand. I did not recognise it at the time, or should have tried to 

 get more. I have already recorded the $ from Chobham, having captured two in 

 1878, but from that time to this I have never met with either sex, but Dr. Capron 

 has taken it at Shiere. 



Andrena argentata, Sm., males common, flying over the sand close to the ground 

 and very difficult to secure. I only met with two females. 



Nomada alboguttata, H.-S. — Of this pretty little species, which is a parasite of 

 the above, I obtained two males and four females. Its flight is very similar to that 

 of the Andrena, but its bright orange coloured body will distinguish it, even while 

 flying. I may here remark that I have looked for Andrena lucens, Imh., every year 

 since I first captured it in 1882 on Burrow Hill, and although I have been in the 

 exact spot at the same season of the year several times, I have never again seen it. 

 I took originally three males in July, 1882, and on the Bank Holiday in August I 

 visited the spot, it was a very cloudy day, but I obtained a single female during a 

 short gleam of sunshine on almost the same plant of Erica on which I had taken 

 the males, and it does seem very strange that year after year one should search the 

 locality carefully and not be able again to meet with it. 



I hope other Hymenopterists will be able to give a better list of captures this 

 year than I am ; the weather has been so favourable that one would have expected 

 Hymenoptera to be unusually abundant. — Edwaed Saundees, St. Ann's, Mason's 

 Hill, Bromley, Kent : Septemher Ihth, 1885.
