December, 



Aeschna Juncea at Inishtrahull. 



Mr. A. O'Leary, keeper of the Inishtrahull lighthouse, has kindly- 

 sent me a specimen of this large dragonfly which he had caught on the 

 island late in October. The species is common in most parts of Ireland ; 

 and on account of its powerful flight, it is not surprising that it should 

 have been able to cross the wide sea-channel between the Donegal mainland 

 and Inishtrahull.

Lepidoptera from East Tyrone and elsewhere in 1920. 



On April 22nd a fresh example of Chloroclysiis coronata was beaten 

 out of Ivy, a very early datQ for this species here ; and on May 3rd a 

 single Enpithecia dodoneata was obtained flying at dusk along a Hawthorn 

 hedge and later a few larvae were beaten from the Hawthorn bloom. 

 Mamestva glauca was observed in some numbers at Vaccinium flowers in 

 the Lough Fea district on May 31st. About the middle of June Apamea 

 unanimis was abundant at dusk among Phalaris arundinacea ; and at 

 Lough Neagh Acidalia inornata was not uncommon, and a single specimen 

 of A crony eta leporina was found at rest on a birch trunk. 



Nearer home, at Roughan Lough, Drepana falcataria was flying over 

 the birches in the sunshine. During July a number of Perizoina bifasciata 

 emerged ; and numerous colonies of larvae of Vanessa io were found 

 on nettles. 



In August Noctua dahlii, Agrotis agathina and Dyschorista suspecta, 

 were all more or less abundant at heather blossom near Tamnamore ; 

 and on the 28th a beautiful female Argynnis aglaia was captured near 

 Grange ; this locality is over thirty miles from the coast. At Stuart 

 Hall in September, Hadena protea turned up again ; two specimens at 

 sugar, one in good condition, the second much worn, was not captured ; 

 at the same time A mphipyra pyramidea was also fairly abundant. 



Quite recently I received from Mr. L, W. Newman, of Bexley, an 

 example of Sesia formicaeformis, bred July, 1920, from Co. Kerry ; this 

 is an addition to the list of our native lepidoptera.

Leucophasia sinapis in Co. Dublin. 



We started collecting butterflies some time ago, and we caught three 

 specimens of the Wood White, which at the time we did not think very 

 rare. A short time ago Mr. Halbert of the National Museum suggested 

 that we should publish a record of the occurrence. We obtained the 

 specimen above Rathfarnham at tlic })lace called " The Little Dargle."
