before in Hampshire, or am 1 now adding a new locality for 

 it? — J. Anderson, jmi. 



Diajithcxicia Albimacula. — Two specimens, a male and a 

 female, of this lovely species, were caught near Folkestone, 

 on the 11th ult., by Mr. Purday, of that town. They are now 

 in my possession, and are not yet dry. No others have been 

 taken up to this date. — E. G. Meek; 56, Brompton Road, 

 S.W., June 15, 1874. 



Geometer Lame Eating Oak-g(dls. — A day or two ago I 

 happened to find some galls (of which I enclose two specimens), 

 of what I presume is Cynips lignicola {s. Koliari), in a young 

 state of development, on some oaks near here. On arriving 

 at home I deposited some of these teuiporaiily in a glass jar 

 containing a few Geometrine larvas, of what species I cannot 

 say. On looking again at them in the evening I was surprised 

 to find these larvae busy eating into the soft, succulent mass 

 of the young gall, and apparently enjoying this strange 

 repast. Whether this habit has been observed before I cannot 

 say, but I have brought it before the notice of readers of the 

 'Entomologist' in the hope of acquiring further information 

 on the subject. — W. A. Forbes; 35, South Castle Street, 

 Edinburgh, Jane 4, 1874. 



Congeries of Diplera. — Reading an article in the 'Ento- 

 mologist' (Entom. vii. 14), on "Insect Congeries," reminded 

 me of a remarkable instance which came under my observation 

 at Whitmore Park about thirty years ago. In a newly-built 

 wing of this house, in one room, I discovered an infinite 

 number of small flies, of which I preserved some specimens, 

 hoping to obtain a name. So numerous were they, that after 

 fumigating the room with tobacco, which quickly brought 

 down the insects Irom walls and ceiling, they lay so thickly 

 on the floor that they were removed by shovelfulls at a 

 time. I did not perceive them in any other room in the 

 house, and to my knowledge have never seen the insect since. 

 Tiie specimens, I believe, are damaged by mites; but if you 

 could name it, from those I enclose, I should be much 

 obliged. — F. J. I'liillips; ff'hitnwre Park, Coventry, June 

 8, 1874. 



[The little flics are Chlorops lineata. This habit of 

 assembling in vast numbers has often been recorded; 

 indeed, Mr. Walker has mentioned it in his 'Diptera
