to another predaceous animal, for a mutilated female of that 

 species was found lying upon a growing leaf ; the contents of the 

 thorax had been entirely abstracted, but the abdomen was left 

 intact. Var. rufescens occurred sparingly at Staines on June 12th, 

 but was quite common at Hartford on August 1st. Specimens 

 were also met with at Byfleet on August 7th ; in one of them the 

 black of segment nine had strongly invaded the blue of seg- 

 ment eight, and formed a large spot of symmetrical outline 

 occupying the apical third of the segment ; a little black from 

 segment seven had also encroached upon segment eight basally. 

 The form of the female known as infuscans was also present at 

 Byfleet on the same date. 



A large colony of Agrion imlchellum, reported to us by Mr. 

 Watts in 1909, was met with at a stagnant pond at Staines 

 on May 22nd. A living male was found there on June 12th 

 entangled in a spider's web, from which, apparently, it was 

 unable to escape. A remarkably small female was also taken ; 

 it measured only 32 mm. in length, and 40*5 mm. in expanse. 

 At Holme (June 20th) a teneral female had a good-sized 

 water-mite lodged on the inferior surface of the tibia of the 

 right fore leg, an unusual situation for such a creature. As 

 early as June 28th (Hartford) some specimens had their wings 

 much frayed, and were obviously very old. Other localities which 

 may be mentioned for the species are Wolvercote, Eamsey, and_ 

 Byfleet. Localities recorded for Agrion puclla were Staines,' 

 Lechlade, Burnham Beeches, Holme, Eamsey, Hartford, and 

 Byfleet. A remarkable male from Gloucestershire, having the 

 lateral branches of the U-shaped spot on segment two entirely 

 separated from the transverse line, has been already mentioned 

 in this magazine (vol. xliii. p. 331). Captures of Enallagma 

 cijathigerum ranged from May 22nd (Staines) to September 13th 

 (Black Pond) ; Lechlade, Wolvercote, and Holme were also 

 among the places at which they were made. Teneral specimens 

 were met with at Byfleet as late as August 4th, and the species 

 was still emerging at the same place on August 7th. A male 

 was obtained having the spot on segment two entirely discon- 

 nected from the posterior circlet (Byfleet, August 4th). On the 

 same occasion a female, without an attendant male, was observed 

 to be getting out of the water of the Basingstoke Canal with the 

 aid of weeds floating on the surface. When taken, it proved to 

 be a female of the straw-coloured form, and quickly resumed its 

 normal appearance and activity. Blue females were obtained at 

 Byfleet (August 7th) and the Black Pond (September 13th) ; the 

 first-named specimens included one in which the antehumeral 

 stripes and the prothoracic spots and border were distinctly brown.
