﻿NOTES ON THE DRAGONFLY SEASON OF 1911. 173 



I took two males on the River Mole. Platycnemis pennipes has 

 been very scarce there this year ; but one or two Erijthromma 

 naias were about at the beginning of July. On July 24th I saw 

 a large Jischna, which I am pretty sure was (jrandis, hawking 

 up and down amongst the motor-buses in Cornhill. On the 

 previous day I saw on the Mole an ^. grandis pounce on a 

 Pieris rapcB which happened to fly near. It quickly bit off the 

 wings of the butterfly and departed with the body in its mouth. 

 During the latter half of August and September I was shooting 

 in Achill Island, co. Mayo, and was surprised to find that the 

 Odonata there were chiefly conspicuous by their absence. How- 

 ever, one or two S, striolatum were to be seen, and also an 

 occasional I. elegans. The weather was not good, and this may 

 account for their scarcity to a certain extent." 



Though the fine weather continued into the autumn, late 

 records for dragonflies were disappointing. On October 1st, 

 near Bedford, I saw one example, which was no doubt S. strio- 

 latum, while at the Black Pond, Surrey, on Oct. 28th, I watched a 

 few which, with still less doubt, belonged to that species. These 

 were the last I saw. Mr. G. T. Lyle, however, found that species 

 common in the New Forest on November 5th. Miss A. Sharp 

 tells me that on November 1st she saw a big one in the New 

 Forest, but could not name it. Assuming it to have been an 

 Mschna, a certain record of it would have been very interesting.

NOTES ON THE DEAGONFLY SEASON OF 1911. 

 By F. W. AND H. Campion. 



Notwithstanding the long and brilliant summer of 1911, 

 dragonflies did not seem to be particularly abundant on the 

 few occasions when we had opportunities for observing them. 

 However, twenty-four species were met with during the season 

 by ourselves or by our fellow collector, Mr. H. J. Watts, and a 

 certain number of the captures made seem to be worthy of 

 mention. 



On August 14th Mr. Watts showed us a male of Sympetrum 

 flaveolum which he had taken the day before at Wisley, Surrey. 

 We visited the same pond ourselves on August 26th, and took 

 two more males, all the specimens which were seen. Again at 

 Wisley, on August 20th, Mr. Watts obtained a female of *S'. dancB, 

 Sulz. (= S. scoticum, Don.) exhibiting a very interesting mal- 

 formation. The tips of both fore wings presented the appearance 

 of a piece of soft paper which had been twisted into a screw 

 between the thumb and forefinger, and the abnormal condition 

 was no doubt due to incomplete inflation of the wings, through
