one female, E. cyathigerum one male and one female, S. strio- 
latum and S. scoticum very common, also an Aschna or two; 
October 11th, HL. cyathigerwm one male, S. scoticum very common, 
S. striolatum ; October 18th, S. striolatum common, S. scoticun 
very common. 
As regards late occurrences Mr. F. W. Campion tells me of 
the capture of a male L. depressa on September 7th at Ching- 
ford in Eissex, and I took a male ZL. quadrimaculata on August 
7th near Beaulieu River in the New Forest. My last dragonfly 
experience for the season was on November 1st when several 
S. striolatum were seen in the New Forest. 
ON THE TRIMORPHISM OF PYRRHOSOMA NYM- 
PHULA (FEmate). 
By F. W. & H. Campton. 
Two important variations from the normal decoration of 
P. nymphula (female) have been known to entomologists for 
many years, and at one time each form was accorded separate 
specific rank. In one of them (var. fulvipes) the black markings 
on the abdomen are greatly reduced in extent, and in the other 
(var. melanotum) they cover practically the whole of the dorsal 
surface. 
Var. fulvipes (Steph.). 
Agrion fulvipes is thus described by Stephens :— 
“Sp. 11. fulvipes. Sanguinewm, nigro-eneo pictum, pedibus rufo- 
fulvis. (Long. corp. 17 lin.; Exp. Alar. 24 lin.) 
“Ag. fulvipes. Steph. Nomen. 2d edit. col. 113. 
‘Head brassy, front red, with two black streaks; thorax brassy 
above, with a slightly interrupted yellowish-red streak on each side, 
the sides themselves and beneath reddish-yellow, with brassy sutures ; 
abdomen blood-red, the five basal segments each with two transverse 
brassy streaks at the apex, the remainder brassy above, with the sides 
and apex red; legs tawny-red ; wings hyaline, stigma pale red. Some- 
times all but the two basal segments of the abdomen are brassy above. 
“Taken at Coombe wood, and near Ripley, in June.”—Ill. Brit. 
Ent. vi. Mand. p. 75 (1836). 
A practical interpretation of this description is afforded by a 
very immature female of P. nymphula contained in the Stephens 
Cabinet in the British Museum (Natural History) ; attached to 
it is the printed name ‘‘fulvipes Step.,” and the well-known 
small oval ticket which distinguishes Stephens’s own specimens. 
Fulvipes varies a little in detail, but it may be separated 
from the normal female by the reduced markings on segments - 
two, three, and four. On two the mid-dorsal black line is very 
weak, and the apical crown-shaped spot is replaced by a wide
