very large pond in the woods there. A few specimens were still 

 about on June 28th. Cordidegaster anmdatiis is frequent every 

 year. I saw Anax imperator first at Trigon on June 20th. 

 Later I noted two specimens at Moreton. Brachytron pratense 

 was in evidence at Holme about the end of May. In June I 

 took it on damp ground covered with rank growth by the 

 Frome at Iford. Feeling certain that I can distinguish 

 Mschna mixta from M. juncea on the wing, partly by its 

 smaller size, but more especially by its very different habit of 

 flight, I can all but positively record three specimens — one at 

 Bindon Abbey, one at East Stoke, and one at East Lulworth. 

 j^. juncea is fairly distributed year by year from Galton to 

 Parley and Arne. AL. grandis occurred at Holme near East 

 Burton, and at Bindon Abbey. Calopteryx splendens is ever in 

 profusion in open flowery tracts by the Frome and its branches. 

 Lestes sponsa is common here, as is also Pyrrhosoma nymphula. 

 P. teiiellum was met with, as is the rule, at TadnoU marsh. It 

 was frequent, too, on Studland Heath. Ischnura elegans, Agrion 

 puella, and Enallagma cyathigenim were once more in force in 

 their haunts. 



I may add that I took eight specimens of A. mercuriale in this 

 immediate neighbourhood, doubtless near the Frome, a few 

 seasons ago. Not distinguishing the species at once, the 

 precise place of capture is unknown to me and I have never met 

 with it again. 



I do not work the Odonata in my leisure more than other 

 orders, and the species named above, with M. cyanea, are all I 

 identified here last season.

July 8th was a very hot day — eighty-one degrees in the shade 

 at noon. Three T. apiformis were taken on poplars, I have 

 lately been breeding a number of Pleris napi from South of 

 Ireland ova — no particular varieties, but some very bright and 

 clearly marked specimens. 



The 11th was fine, bright and hot, with a fresh north- 

 easterly breeze. I went to the distant woods, as I wanted some 

 fresh Argynnis adippe, but I only saw one specimen of that 

 species, seven or eight Limenitis sibylla, and about a couple of 

 dozen A. paphia ; these three species used to swarm in these
