of the nioutli-pnvts to be the same as in that ^emis;, in which, tlierefore, it must 

 be placed. A very closely allied species, at present uiidescribed, occurs in the 

 vicinity of Port Darwin (N. W. Australia) and in Sino^apore, in a similar

The. asaociitfion between the Hemiptern- Heferoptera and vef/ptdtion : nn 

 addendum. — The publication of my paper on this subject has brought me the 

 record for which I have for years been loolnns: in vain, that of the occurrence 

 of a heteropterous bug on an orchid. Mr. AV. Evans, of Kdinburyh, has called 

 my attention to a paper of his on insect visitors to certain orchids, which was 

 ])ublished last year in the "Transactions and Proceedinrrs of the Botanical 

 Society of Edinburgh." In this paper he records lindinfr, in August 1909, one 

 specimen each of Pithanns maerJceli and Li/gus liicornm on a plant of TAstera 

 ovata. As these two species are. t;re«rarions on their r?a:ular food-plants, while, 

 in this instance, only one specimen was found in each case, the nccuiTeuce is 

 scarcely likely to have been other than casual ; but still it forms the exception, 

 and it is interesting to note that it come.? from Scotland, which has been much 

 less Avorked for Hemiptera than England. I may add that those Heteroptera 

 that frequent flowers may occasionally serve as agents in pollination, as thev 

 are sometimes found with pollen-grains adhering to them. — E. A. Butler,

Snpyga chtvicornis L. and other Hymenoj^tera, in old posts at Oxford. — 



I am pleased to be able to record the capture of a male of this rare Fossor on 



an old pc/St in my garden, Sonthfield Road, late in the afternoon of June 1st. 



For some years past I have kept under observation, mo.stly at week-ends, a 



couple of old willow-posts, which had formerly done duty as clothes-posts, but 



becoming unsuitable for that purpose, they were lied to the fence, one on 



either side of the garden ; consequently one is more or less in shade, and the 



other, which gets all the afternoon sun, is always the more attractive. Into 



them I have bored a number of gimlet-holes of various calibre, w^hich attract 



large numbers oi Aculeata and other Hymenoptera. The following rough and 



ready list will give some idea of the success of the method adopted. I have 



no doubt that many more species could be attracted if materials for nidificating 



purposes, to suit all tastes, were provided. Apart from their interesting 



habits, it is an endless source of amusement to watch the many species at 



work or on pleasure bent. On a bright sunny day in June it is no unusual 



siirht to see VI to 20 species on or about the posts at one time.

FossORES. — Sapyga qtiinqiie punctata, both se.ves seeii^ every year. 7'/?/- 



po.^ylon Jiyulus and clavicerum breed regularly. Stiymiis solshyi, breeds every 



year in some numbers, appropriating the small borings left by Anobium. 



Pemphredon, three species, occasionally nidilicatiug. Diodontus, all three 



species, sparingly. Passaloecus, one or more species sometimes. Pseyiulvs 



jiullipes, occasionally nidificating. Q-abro, seven or eight species ; the^e 



include both large and small forms. Spilomena troglodytes has just been taken 



b}' me. This minute Fossor nidificates in the small burrows of Anobium) 



■which I have seen it enter with its prey, an immature Aphid. 



DiPLOPTERA. — 0(ZywerM5, several species ; many individuals are attracted 

 but seldom nidificate.
