was very common. These insects were more abundant on the 

 banks of a lane adjacent to the pool than at the margin of 

 the water. I found no other Agrionidse in North Wales. 



Of Lihellula depressa, Linn., one fine male was caught on 

 the golf-links near the sea-shore, two or three miles from any 

 pool which looked a likely breeding-place. 



From July 5th to the 12th I was at Llanbedr, Merioneth. 

 Here in the ditches which intersected, the Morpha C orduleg aster 

 assulatus, Latr., and Orthetrum cceridescens, Fabr., were common. 

 Of the former I caught several males, but no female ; whether 

 I saw one or not I do not know. Both sexes of 0. canilescens 

 were common, but all were rather damaged. On a very narrow 

 reed-bordered mountain stream both sexes of Calopteryx virgo, 

 Linn., were common. C. annidatus was also found in the same 

 situation. 



In a small glade in one of the woods, half a mile from water, 

 a newly-emerged C. virgo was found. The wings lacked the 

 blue pigmentation except for a beautifully metallic costa. In 

 this same small glade were found L. depressa, $ and ? , 

 0. cceridescens, 3" and ? , and C. annidatus, ^ . This female 

 L. depressa was the only one I have ever seen, aud unfortunately 

 I could not catch it. I have caught the male m four different 

 parts of tbe country, but in each case it has been a solitary 

 specimen, no other being seen in the neighbourhood. 



With the exception of Calopteryx splendens, Harr., and 

 Platijcnemis pennipes, Pall., taken later on the Severn, this 

 completed my collecting for the year. The smallness of the 

 record was due in great measure to the unfavourable weather 

 conditions prevailing during the time at my disposal.
