The Natuealist. 



Adliena lideata. — One or two at Hawkswortli, where it occurs 

 annually. Very local. 



Eupisteria Jieparata, — A few about alders at Hawksworth and 

 Bingley. 



Vemisia camhricaria. — Not so abundant as in some years. I bad the 

 pleasure of taking one at Shipley Glen, which is a new locality for the 

 species. 



Acidalia scutulata. — A few near Cottingley. 



A. fumata. — Extremely abundant, but local, flying over heathy, 

 Bingley wood. 



Scodiona oelgiaria. — Common. 



Abraxas nlmata. — Has been rare at Hawksworth, where it usually 

 swarms. 



Eybernia leucopJiaaria, aurantiaria, progeonmaria, and defoliaria.— 

 The larvae of these species were to be seen in thousands at Shipley 

 Glen in the month of June, hanging by their silken threads from every 

 tree, every leaf of which they had devoured. Thousands must have 

 died of starvation, and a great number pupated long before they were 

 full-fed. In the month of* November the imagines of aurantiaria and 

 defoliaria were abundant enough— the latter in every conceivable 

 form, including one specimen of a dark unicolorous variety which is 

 rare. 



Gheimatohia, horeata. — Extremely abundant. 



Larentia salicata. — Two or three at Shipley Glen and Bingley wood. 

 In the former locality it is found in the day-time, resting on lichen- 

 covered rocks, with which it very closely assimilates, and is conse- 

 quently sometimes very difficult to detect. Newman says that this 

 species is "on the wing early in June, and again in August," thus 

 implying that it is double-brooded. Is it so ? We have taken it from 

 May 18th to the end of June, but have looked in vain for an August 

 brood. It seems strange if it should be double-brooded in more 

 northern localities. In some years it is very abundant. 



L. olivata. — Moderately common at Shipley Glen ; a few in Bingley 

 wood. In the former locality it is confined to a space of 309 or 400 

 yards by the stream side, and may be dislodged, in the daytime, from 

 the old walls with the beating-stick. My friend Mr. E. P. P. Butter- 

 field (to v^hom I am greatly indebted for a good supply of interesting 

 notes, which I have made free use of here) informs me that at the 

 latter place it is confined to one particular cave ! All the species of 

 the genus Larentia occur in Airedale.
