8 THE ENTOMOLOGIST. 



dark and the saffron strongly marked. On this occasion we 

 were able to confirm what we had observed in a previous year, 

 that the eyes of the female are wholly green, little if at all 

 inferior, in richness of colour, to the splendid eyes of the male. 

 De Selys is quoted in Mr. Lucas's book as stating that in the 

 female there is a "chestnut tint to upper surface of eyes," but, 

 so far as the adult insect is concerned, this statement is not in 

 accord with the observations here recorded. A female was 

 observed to be ovipositing on June 21st. By July 12th, when 

 the last specimen was obtained, the species had become very 

 scarce, and it was noticed that the eyes of the male then taken 

 were losing the translucent green observed so recently as a week 

 before, and were acquiring a tinge of chestnut. 



(3) Agrion puella, — The first specimens were taken on May 

 31st and the last on August 16th. On June 28th a male was 

 obtained while feeding upon a small moth, which had already 

 lost its head and its left hind wing. The prey was identified as 

 Tortrix viridana, and the identification was kindly confirmed by 

 Mr. E. South. The form of the female having cuneiform blue 

 spots on segments three to six occurred on June 21st and July 

 5th and 12th. 



(4) Ischnura elegans, first taken on May 31st, continued to be 

 met with until August 30th. The form of the female known as 

 riifescens was taken on July 12th and 26th, and the form named 

 infuscans on June 14th and 2l8t, July 5th and 25th, and August 

 30th. 



(5) Enallagma cyathigerum was found in flight from May 31st 

 to Sept. 12th. On June 8th a male was taken with the anterior 

 portion of the spot on segment two entirely disconnected from 

 the circlet behind ; the spot closely resembled the exceptional 

 marking numbered 1 on plate xxvii. of 'British Dragonflies.' 

 A female of the type (blue) form was collected on July 12th. 



(6) Lihellula depressa was first seen on the wing on May 31st, 

 but no specimens were taken before June 28th. The latest 

 capture was that of a single male on September 7th, an extremely 

 late date for the species. Notwithstanding the fact that this 

 year's specimens (four males) were obtained from widely separ- 

 ated parts of the Forest, they all differ in a marked degree from 

 those taken in other seasons in having the abdomen narrow and 

 strongly triquetrous, instead of broad and flattened, 



(7) Erythromma naias was met with by us for the first time 

 in Epping Forest on June 14th, when it was in fine condition and 

 fairly well distributed along the margins of one of the Forest 

 ponds. It was seen again on several occasions, at that and 

 other ponds, but specimens were then difficult to get, owing 

 to their usually flying well away from the banks, and resting 

 upon the floating leaves of Potamogeton. In such circumstances 

 they were very liable to be mistaken for I. elegans or overlooked
