MICROPTERYX AUREATELLA. 159 



just above the feet, has two, one in front of the other. The 8th 

 abdominal segment has one appendage in this row, but above this has 

 two transverse rows of two on either side ; the 9th segment has three 

 on either side, and the 10th segment carries the two seta3, which 

 appear to be rather homologous with cerci, than with any ordinary 

 tubercles or processes of lepidopterous larvae. It appears also to have 

 a similar sucker to that of M. calthella, but I did not happen to see 

 it obviously used in the living larva (Chapman, in litt., 25/3/98). 



Habitat. — This appears to be somewhat of a moorland species, 

 although also recorded from wooded districts, and Barrett notes it 

 as occurring in a swampy copse near Haslemere, on sedge-blossoms. 

 Edleston reports (Ent. Ann., 1855, 1st Ed., p. 52) having seen 

 many hundreds of specimens, invariably among Vaccinium myr- 

 tilhis, flying over and settling on the plants. Madam Lienig 

 records it as occurring in small woods in Livonia, flying in sunny 

 places over F» myrtillus gregariously at the end of May. Meyrick says 

 that it is abundant on the hills at Philippeville and Bougie, resting on 

 flowers in the sun. (Probably this record refers to M. algeriella, Bag.) 

 Wilkinson says that at Scarborough it loves to fly about the flowering 

 spikes of wood-sedge (Carex sylvatica) in the sun. Frey gives the 

 species as being found on the highest Alps, and Zeller says that it 

 occurs in the Silesian mountains, near their summits, in wooded 

 thickets, but is rare. Among grasses and sedges at Wilsden (Butter- 

 field) ; abounds in woods near Huddersfield among bilberry (Porritt) ; 

 in moist woods and meadows at Carlisle (Wilkinson) ; among bilberry, 

 but settling on leaves of nut in the early morning sunshine, in North 

 Devon (South) ; flying among the heather at Witherslack (Shuttle- 

 worth) ; flies over the moors at Witherslack, but occurs also in damp 

 woods at Windermere (Threlfall) ; beaten out of small birch trees in 

 damp spots in Tilgate Forest (Vine) ; on flowers on mountain-ash at 

 Airthrey (Stainton). 



Time of appearance. — Stainton gives May and June for Britain ; 

 Zeller, at the end of May and beginning of June in the Silesian 

 Mountains ; Zetterstedt says that the species is not rare from July 

 3rd-22nd in Bjoerkvik in Lapland ; Tengstrom gives June and com- 

 mencement of July for Finland ; whilst Madam Lienig gives the end 

 of May for its appearance in Livonia. In Algeria at Philippeville, 

 etc., it occurs in April (Meyrick). Other recorded dates are : —
