﻿50 [August, 



doubt been blown by the wind from the aspens of the " Judenberg," 

 probably at five minutes' distance : there it may be freely beaten from 

 the aspen leaves, from which I have also bred it. 



On the leaves of a sallow bush 5 near the canal, I took a beautiful 

 <J of the rather scarce Acidalia deversaria, H. S., fig 305 — 308. On a 

 grassy place, I started some Anerastia lotella, mostly already worn ; 

 I also saw a $ Grambus luteellus and took a Sophronia parenthesella. 

 On dry saridy places, where Mieracium pilosella grows very abun- 

 dantly, Pterophorus tristis was already mostly in bad condition, showing 

 that the first brood was nearly at an end ; the Pterophorus ohscurus, 

 which occurred singly amongst them, showed by their freshness that 

 they certainly came out later than P. tristis. 



I then went to the other side of the canal, which has quite the 

 Bame soil and vegetation, in order to obtain some shelter from the wind 

 behind the embankment of sand at the side. On this embankment, 

 Gnaphalium arenarium and Artemisia campestris grow very plentifully ; 

 on the former plant flew JBotys cerealis and Thalpochares paula. By the 

 aid of my cigar smoke, I induced Bucculatrix gnapfialiella to come out 

 in numbers ; Gelechia inopella also flew out not unfrequently, yet already 

 the specimens were mostly very bad, it was much more agile than 

 the Bucculatrix, and was generally carried away by the wind. Some 

 Gelechia pictella also turned up here, though there does not appear to be 

 any Oerastium round about for the larvae to feed on. Of Stagmatophora 

 pomposella, which, viewed superficially, seems so similar to it, and which 

 probably came from the Gnaphalium, I took one specimen. Sophronia 



nivea," and "palpi albi," appear to me truly to refer to neglectana (Wilkinson, Heinemann). 

 The " alse basis" and the "fascia" designated as "fusca," which seems more applicable to 

 Wilkinson's dealbana, may be of less importance ; since Wilkinson also speaks only of " fascia basalt 

 mediaque cinereo-obscuris." Of much greater importance is Frolich's notice, "caput cinereum," since 

 he describes much too inaccurately, and may by the "palpis albis" also have intended to designate the 

 white colouring of the face. Probably he had confounded the two species, as so many Lepidopterists 

 hare since done I 



The observations of Wilkinson and von Heinemann do not agree with my experience. Neglectana 

 according to Heinemann should appear in July, dealbana from June to August. Of my 14 specimens 

 of neglectana, 7 have the date attached, according to which I took them at the end of May and begin- 

 ning of June; one 9 from Reinerz, thus at a considerable height above the sea level, I took June 29. Of 

 30 specimens of dealbana, Wilkinson, unfortunately only 4 have labels; these, however, are all in the 

 first ten days of July. 



I have both species from Livonia; the two specimens In my collection from Tuscany are neglectana 

 (Ent. Zeitung, 1849, S. 239, dealbana "at the beginning of May not scarce," which also agrees with my 

 own experience). 



I have reared the larva of this neglectana. I found it on aspen-twigs, which I had placed in water 

 in the room, in March, when the leaves were coming out ; it was in a bud, which was already drooping 

 from the effects of the larva feeding. It was about six lines long, rather thick, flesh-coloured, rather 

 inclining to dirty-yellowish. The head small, rather heart-shaped, with a faint depresssion above, 

 shining black, thoracic shield transverse, broad in the middle, attenuated at the sides, shining black- 

 brown with a fine pale longitudinal line in the middle. The spots are pale-brownish, two on each 

 abdominal segment, near the dorsal vessel, the hinder one farther from it than the anterior one; above 

 the similarly coloured spiracles are two perpendicularly one above the other, the upper one larger on the 

 middle segments; beneath the spiracles is the "Wulstrand ;" below which, perpendicularly beneath the 

 spiracles, is another spot. The anal plate is shining brownish. The pectoral legs blackish. The hairs 

 on the spots, which are imperceptible to the naked eye, are almost colourless. It crawled rather quickly 

 • long a smooth surface. When I had placed it again on a bud, it soon bored in between the leaf-scales 

 »nd closed up the place with a flight white web. The imago appeared in the room in April. — P. C. Z.
