MYRMECOPHILOUS NOTES FOR ISKHI. 15 



Catnlora nii/ita was fairly common, as usual at the street lamps (all 

 males Blackheath), also Ennonins tiliaria (alnian'a), and T/iera rariata 

 (last named locality). 



October, at Chislehurst, saw great numbers of On-limUa iaai>iii 

 both at sugar and at rest on the tree-trunks, a very fine series being- 

 secured, including most of the known aberrations. Only one specimen 

 of Onhodia liijiila was secured, though several hundred specimens of the 

 genus were examined. ScniH'ldsonia (Kii})silia) safellitia was very 

 common, but there were few J//.sx'//« o.vijacantliae, though both type and 

 ab. cajiiirina were taken. During both October and November, Hiiiiera 

 jicnnaria, including well-suffused examples, were attracted to light or 

 found at rest on birch twigs, as well as Hybernia defulian'a and H 

 aurantiaria, Chriniatobia hrtimata, ('. horeata, and Oporabia Jilutato. 



Myrmecophilous Notes for 1909. 



By H. St. .J. K. DONISTHORPE, F.Z.S., F.E.S. 

 [Concluded from vol. xxi., p. 291.) 



Chalc'idid.e. — SpalanctIa erythkomkra, Foerst. — This species 

 occurred with its usual host, Imsjiis fnliiii)it)^iis, at Darenth Wood, in 

 July. I have taken various other Chalcids in ants' nests, but have 

 been unable to get them named at present. 



HeTEUOPTERA. PlEZOSTETHUS FORMICETORUM, Boh. — I tOok this 



insect sparingly with Foriinca riifa at Nethy Bridge, in May. This is 

 another new locality for the species. It has now been found at 

 Braemar, Rannoch, and Nethy Bridge in Britain. 



Bracomd.e. — EuPHORUs BisTiGMATicus, Morley, Kut. Mu. Maij., 

 1909, p. 212. — T captured 2 s hovering over nests of F. rufa at Wey- 

 bridge and Bewdley Forest, in July. It was first taken in Britain by 

 me at Weybridge, in July, 1906 (see Ent. llec, 1907, p. 5), and I 

 bred a g in my F. rufa observation-nest, June 13th, 1907 (see Fnt. 

 Fiec, 1907, p. 256). Mr. Hamm has taken it over /''. rufa nests in the 

 New Forest. Wasmann has found it at Luxemburg with F. nifa and 

 F. pratensis. The 2 s hover steadily over the ant, gradually getting 

 nearer, and when they get the chance strike at it to lay an egg. The 

 ants often notice its presence, and reach up to try and drive it away. 



Spilom.ma falconivibrans, J^Jorley [Ent. Mo. Ma;/., 1909, p. 211). — 

 Morley has described this new genus and species from specimens, J s 

 and $ s, bred by me in an observation-nest of F. fuKca, from Porlock 

 (see Ent. Hec, 1907, p. 255). 



Pachylomjia buccata, Breb. — I captured a 2 hovering over a nest 

 of Lasias niijer at St. Helens, Isle of Wight, on August 29th. In the 

 Ent. Mo. Ma;/., 1909, p. 209, Morley records the few known British 

 examples. Marshall found the 2 s associating with Mi/nnica scabri- 

 nodis. Giraud found both sexes hovering over a society of very little 

 ants. De Gaulle found it associated with Lasius bnonwns and .W. 

 scahrinodis. 



AspiLOTA NERVOSA, Hal. 3 .—This is a small Braconid that I took 

 in a nest of Laaius fuliiiiiiosKs, last June, at Darenth Wood. I sent it 

 to Morley, who writes as follows : " I am satisfied that it is Aspilota 

 nervosa, Hal., of which Marshall gives a lot of vars., which he thinks 

 are probably all good species. Yours is var. 6, of which only the <? is 

 known." These Braconids are parasitic on diptera, and it is most
