302 THE entomologist's record. 



Fauvel records L. Inctnam from near the Grande Chatreuse. 

 Captain Deville, who possesses two or three examples, bat was unable 

 to lend mo one as his collections were all packed up to be removed to 

 Paris, writes that "Here L. luctuosa is a mountain species, it is known 

 from the Alps, Auvergne, and Pyrenee?." 



I could no doubt have obtained more specimens, but just about the 

 time I captured it a very thick white mist rolled up, and I found I had 

 lost my bearings, my compass went wrong, and the rest of the day was 

 spent in a frantic endeavour to find my way home. Eigg is a small 

 island near the Isle of Mull, in the inner Hebrides, off the West Coast 

 of Scotland. 



j^ClENTIFIC NOTES AND OBSERVATIONS. 



Dwarf Aberrations of Pieris napi. — Nomenclature. — I have read 

 in the Kntomdoiiht's Fwcord, vol. xxiii, no. 10, p. 273, Mr. Muschamp's 

 remarks on " The Abundance of Pieris napi, etc." The author speaking 

 in his note of Pieris napi of small size, 29-31mm., makes of it a new 

 aberration under the name niini)iia. In 1902, in my work on the 

 Butterflies of Behiinin, p. 18, I gave the name «fl/**'ZZrt to those examples 

 of P. napi, measuring 28mm. in expanse. This was repeated in my 

 Cataloqiie of tlie Butter flies of Ijelgium in 1903 and 1907. In the same 

 year (i902J Baron de Crombrugghe, in the Ann. dela Sac. Ent. de Belg., 

 vol. 46., p. 20., gave the name of var. minor to examples of P. napi 

 measuring 30mm. This was after my own name napella had been 

 published. Thus there are three names for the same aberration of 

 P. napi, ab. napella, Lambil. = ab. minor, Cromb. = ab. )uiniiua, Musch.

Pieris napi ab. napella (minima, Muschamp) anp other dwarfs. — On 

 August 17th, when idling in one of our Guernsey lanes, I came across 

 two delightful specimens of buttertiies of an extraordinary diminutive 

 size. The first was a perfectly fresh /'. napi J. This specimen 

 measures only 28mm. in wing expanse, or lY^iin. according to our 

 English scale. It is therefore as small as the smallest of Mr. 

 Muschamp's interesting captures at Stilfa, but I saw no others. The 

 coloration and markings are as in the spring brood, not as in the late 

 brood, as might have been expected. Both last year and this year the 

 " whites" have been excessively abundant. The same day, and within 

 a few yards of the same place, I took a male I'aran/e ae^eria var. 

 intermedia, our Guernsey form. This measures only 31mm. across the 

 wind's. P. aeijeria, too, has been unusually abundant with us this 

 autumn, as has also /*. meijaera, the latter is still on the wing in a few 

 places (October 19th). But both these two species have been singularly 

 line, indeed, it was while watching and admiring the special beauty of 

 a number of /'. aeijeria clustering on a bramble bush, that I noticed 

 the above dwarf. In the spring, and therefore before the influence of 

 the long drought had been felt, I took a very perfect freshly emerged 

 Celastrina an/iidus ?, which would be small for Saditantides baton, 

 measuring only 22inm. So far as I saw, specimens of other species 

 came up to the normal standard of size. It seems probable that the 

 individual experience of larvas— especially of the sluggish sort — has 

 more to do with stunted growth than climatic considerations. Either 

 because feeding on an isolated plant, which affords too little food, or
