over the surface of the water, close to the banks, but the specimens thus taken 

 were nearly all males evidently in search of the females. I netted four couples 

 paired, all tlu^ males mature, biit three of them paired to immature females, 

 showing that the latter are paired soon after emergence. On the previous days, 

 when I had taken them on the banks, females were greatly in the majority. 

 When flying in the smi the matiu-e insect is a very striking Agrion and cannot 

 be mistaken for any other British species ; the green on the front and posterior 

 segments of the abdomen shines like emeralds, and is more brilliant than is the 

 blue in Agrion piiella, A. pulcheUuvi, &c. I took one specimen, a female, in 

 which the green was entirely replaced by a beautiful clear blue, forming 

 a striking contrast, but it was the only mature specimen I saw which departed 

 from the green marked, and evidently ordinary form in the Broads.* My friend 

 Mr. W. J. Lucas will, I am sure, forgive my pointing out that his figiu-e of 

 segments 1 and 2 of this species (" Entomologist," February, 1904) is not quite 

 accurate in its details. The two black marks are there shown as being on the 

 dorsal part of the segment ( J ), whereas in reality they are on the sides, and 

 can scarcely be seen at all when the insect is looked at from above. Then the 

 neat conical mark in the figvu'e, which ptirposes to represent the male, is 

 characteristic of the female only ; in the male tlie mark is almost square and 

 occupies the entire Avidth of the segment. 



Other early dragon-flies were mucli in evidence. Lihellula quadriinaculata, 

 Erythromma naias, Pyrrhosoma nymphula,, IscJmura elegans, and Agrion pul- 

 chelluni were all plentiful ; Brachytron pratense was common, and Lihellula 

 fulva was getting nicely out, but the specimens as yet, of covu-se, immatiu'e. 

 Of Trichoptera, Phryganea striata, Glyphotxlius pellucidus, Agrypnia pagetana, 

 and Limnophilus xanthodes were all abundant ; and Liynnophilus niarmoratus, 

 Molanna angustata and several other species were less common. No evening 

 work was attempted, as I had to leave the Broads in the middle of the after- 

 noons to catch my train, or probably the list of these insects could have been 

 considerably lengthened. Nor was any attention given to Le'pidoptera, but 

 Papilio machaon was getting oiit, and hibernated Vanessa io were not imcommon 

 depositing eggs on the large patches of nettles. — Geo. T. Poebitt, Dalton,

A street blocked by a moth. — The following rather amusing incident is 

 extracted from the '• Gibraltar Chronicle and Official Gazette," dated May 4th, 

 1910 : — " A very large moth was the means of drawing quite a large crowd, and 

 causing some commotion in the Main Street, just outside the ' Welcome,' about 

 9 o'clock last evening. It was a remarkably large and rare-looking specimen, 

 and somewhat resembled one of the larger sized bats, which most of the 

 spectators took it to be. Attracted by the glare of the electric street lamp, it 

 fliittered about before it was detected by some boys, who were hastily on its 

 track. After a few minutes' diversion on the wing, it settled on the wall of the 

 Spanish Pavilion, about twenty feet from the ground, where it became an 

 interesting target, and had to stand the bombardment of hundreds of caps,
