THE DRAGONFLIES OF EPPING FOREST IN 1909. 295 
spects:—¢: The following parts are apple-green, not yellow— 
longitudinal stripes on thorax, sides of thorax and of segment 1, 
wing-bases and prominences between them. ¢ (Adult): Eyes 
blue above and brown below; sides of thorax and of abdomen 
apple-green. 
(7) Erythromma naias.—Two freshly emerged females taken 
on May 30th exhibited a dull-green coloration, with purple- 
bronze on the upper surface. The eyes of some fully adult 
females taken on August 4th were noted as being reddish- 
brown above and yellowish-green below. One specimen was very 
small, its length being only 84°5 mm., and its expanse only 
45 mm. It is interesting to compare this female with an un- 
usually large one netted in the same locality on June 14th, 1908 
(length 38 mm., expanse 51 mm.). 
(8) Enallagma cyathigerwm was not observed until August 
4th. On August 15th a blue female was obtained, as well as a 
male having the spot on segment 2 entirely disconnected from 
the circlet behind. A male caught on September 12th was dis- 
covered to have prey in its jaws, which turned out, upon exami- 
nation by Mr. Charles 0. Waterhouse, to be portions of a gnat 
(Culex sp.). 
(9) Anas imperator was first seen on August 4th, and a 
male was taken on the 15th of the same month. 
(10) Afschna grandis.—On August 4th a newly emerged 
female was found and mature specimens were seen in flight. On 
August 8th and 29th females were busy ovipositing. 
(11) Sympetrum striolatum.—On August 4th, when the species 
was first met with, a fully-matured male was found, as well 
as teneral specimens. A partially consumed insect, determined 
by Mr. Waterhouse as the remains of a Muscid fly, was extracted 
from the jaws of a male taken on September 5th. The last 
specimens, a male and female, were taken on October 24th. 
(12) Calopteryx splendens. — A visit was paid to the River 
Roding on August 15th, and a fine male of this species was 
secured ; a female was also seen, but not taken. 
(18) Afschna cyanea was taken for the first time on August 
15th, and for the last time on September 12th. 
(14) Sympetrum sanguineum. — Three males were obtained 
on August 29th. One of them was of the largest size, and 
another was exceptionally small, measuring only 380°5 mm. in 
length, and 49 mm. in expanse of hind wings. Some of the 
males taken this year, like others taken in previous years, show 
the strongly marked constriction of the abdomen, at the suture 
between segments 8 and 9, seen in Charpentier’s figure of his 
Libellula nigripes (= sanguineum, Mull.). 
(15) Lestes sponsa was found to be present in some numbers 
when Coopersale Common was visited on September 7th. In 
view of the Abbé Pierre’s discovery of the gall-making habit of
