THE DRAGONFLIES OF EPPING FOREST IN 1905. 37 



June 4th in a much damaged and nearly dead state on the banks 

 of a pond which the species usually frequents. The left hind 

 wing was in a shrivelled condition, and the insect's presumably 

 imperfect powers of flight may have led to its destruction. 



(5) Lihellula depressa was first seen and taken on June 18th, 

 and afterwards became pretty plentiful ; it was not noticed later 

 than July 2'2nd. 



(G) Enallagma cijatJiifierum. — It is curious to note how far 

 from water this species, and especially the females, will some- 

 times travel. We have already recorded (Entom. xxxvi. 49) the 

 occurrence in 1902 of a female in our garden at Walthamstow, 

 which is fully halfa-mile distant from any sheet of water. -The 

 first capture of the past season was a solitary female found in the 

 Forest on June 25th quite a long way from water, and another 

 female was taken at rest in our garden at about 5.30 p.m. on 

 July 2nd. A male was taken at rest in one of the rooms in our 

 house on July 23rd, but no specimens were taken anywhere after 

 September 3rd. 



(7) Sijmjjetruvi striolatum. — A single immature specimen was 

 seen and netted on July 16th ; it had just emerged from the 

 water, and we found its empty nymph-case clasping a neighbour- 

 ing rush. Two weeks later the species was still immature. The 

 last specimens occurred on September 18th. 



(8) Mschna grandis. — The earliest specimen seen was a male 

 taken on July 16th. On the 22nd of that month we took a 

 female which was ovipositing in a pond, and found that more 

 than half the length of its abdomen — that is, part of segment five 

 and the whole of segments six to ten — had been thrust below the 

 surface of the water. The species was collected pretty frequently 

 until September 3rd. 



(9) Mschna cyanea. — The first representative of this species 

 was seen on July 30th. It appeared to be flying in a perfectly 

 normal manner, but, upon being taken, it proved to be a terato- 

 logical male. Both the wings on the right side looked as though 

 the tips had been scorched by fire, and the hind wing was con- 

 siderably shorter and broader than the corresponding wing on 

 the other side. Pterostigmata were absent from both wings. The 

 right hind leg was also malformed, the tarsus being represented 

 apparently by a single short joint divided at the extremity. 

 Another male, taken on September 18th (the latest date for this 

 species), had the left hind leg in a still more rudimentary state, 

 the tibia being abnormal as well as the tarsus. 



Not a trace of JEsclma mixta was met with, notwithstanding 

 the strictest search made at the proper season and in its favourite 

 haunts. Another and more remarkable omission from the year's 

 dragonfly list for this locality was the total absence from the 

 ponds which we habitually visit of the usually common little 

 insect, Lestes sponsa.
