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) Enjthromma 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 34-5 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 cyathigeruin 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) Aiia.v imperator was first seen on August 4th, and a 

 male was taken on the 15th of the same month. 



(10) Mschna 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 striolatiim. — 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) Caloptcryx spleiidens. — A visit was paid to the Eiver 

 Eoding on August 15th, and a fine male of this species was 

 secured ; a female was also seen, but not taken. 



(13) Mschna cyanca 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 30-5 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 Charpeutier's figure of his 

 Libellula nigripes (= sanguineum, Miill.). 



(15) Lestes sponsa was found to be present in some numbers 

 when Coopersale Common was visited on September 7th. In 

 view of the Abbe Pierre's discovery of the gall-making habit of
