similar but smaller than the g, and somewhat more distinctly 
marked, it is, however, hardly so clearly and neatly fasciate 
as is the 2 of duplana Hb., moreover the direction of the 
fasciae is not precisely similar, and the dark scaling along the 
tornus of the fore-wings is a good distinguishing character 
in logaea. Specimens doing duty as duplana and posticana in 
British collections should be carefully examined—these will 
probably be found to be mostly loyaea. At present Mr. 
Durrant said he had only seen two specimens of dupluna. 
These were purchased from Meek by Lord Walsingham, as 
British, in 1868, and it would certainly be satisfactory to 
examine others with a better record. These two specimens of 
duplana, Hb., ¢ and 9, as also both sexes of posticana, were 
exhibited for comparison. 
CoLiaps FROM BerksHIRE.—Mr.J. H. Durrant also exhibited 
eighteen specimens of Colias taken by himself in a field of lucerne 
at Barcote, near Faringdon, Berks, from September 4-10, 1892. 
These comprised both /yale (2) and edusa (14) and two aber- 
rations of the latter, one of a very light orange colour (ab. 
helicina) and the other a fine ab. delice. All the specimens of 
C’. edusa were of a yellowish-orange tint. 
SyMPetRuM ronscotompu.—Mr. W. J. Lucas exhibited 
specimens of Sympetrum fonscolombii, and read the following 
note :— 
‘“On August 4 last, ata pond in the south of the New 
Forest, I saw some dragonflies of the genus Sympetrum, very 
much more brilliant than the common S. striolatum. After 
some time I managed to capture one, and found it to be a 
male of S. fonscolombii, a species very seldom taken in Britain, 
and quite new to the Forest. It isa restless insect, which settles 
very frequently, but, nevertheless, is very difficult to capture. 
I visited the pond again on August 7, 8, 25 and 29, and as a 
consequence of the five visits obtained a short series, all but 
one being males. SS. fonscolombii is usually considered to be 
a casual visitor only to our shores; but one or two things in 
this case seem rather to throw doubt on this supposition. 
For one thing the date is a late one, then the insects on my 
first visit to the pond were very fresh; again, one was a 
female, which looked even fresher than the males; further,
