conducted into the Obra. The occasionally high banks of the canal are 

 clothed on their slopes with an abundant grass-flora, but higher up are 

 only the fir woods with their scanty vegetation. 



The 29th op Mat. 



After a long period of very cold weather, which had totally 

 destroyed the orchard crops and partially injured the rye, at last for a 

 few days milder weather had set in. It had rained in the forenoon of 

 this day and was warm ; the sun, however, shone out before evening. 



In order to collect Gelechia superhella, and the larvae of Setina 

 Kuhlweinii, and to see the oviposition of the Lyccence Hylas and Medon 

 (Agestis), which I wished to rear, I went at 3 p.m. to the Judenberg. 

 As I did not stop on my way, I only saw, not far from the suburb, a 

 LitJiostege farinata (niveata) on the wing coming from the fields, and 

 afterwards, on a field, another. 



From the aspens of the Jews' burying-ground I beat a beautiful 

 female Cymatopliora or, and not unfrequently Phoxopteryx karpana, and 

 from the aspen bushes a beautiful Acidalia immutata £ . 



In the open places which were more grown over with Festuca and 

 Corynephorus, Orambus chrysonuchellus occurred in tolerable plenty, 

 these were already accompanied by a few G. pratellus. "Whilst I was 

 seeking amongst the lichen (which covers the ground here and there 

 like a grey efflorescence) for the larvae of Kuhlweinii, there flew up at 

 intervals a few bad Gelechia psilella, two G. desertella* and a quite 

 fresh G. umbrosella, Z.f I found by degrees 4 larvse of Kuhlweinii, 

 which sat partly concealed under a clod, and 4 larvae of Lithosia 

 arideola of medium size. To my surprise, 2 Kuhlweinii $ flew off 

 from grass stems, certainly quite fresh out, but after such a long period 

 of cold weather I had not expected them. 



Whilst poking amongst Thymus serpyllum, I turned up by degrees 

 20 Gelechia superhella, their white beads at once striking the eye, with 

 their antennae obliquely directed upwards, they flew rapidly for a short 

 distance and then settled again on the ground to take another hiding- 



* By desertella, I understand those specimens which are so similar to tcrrella that they might 

 readily pass for that species, but which are smaller, paler, and generally more sharply marked, and with 

 us first make their appearance as early as the last third of May. The characters given by Stainton 

 (Insecta Britannica, p. 113) are not always suitable; even the size is no constant character, and there 

 remains hardly any other of tolerable certainty, except the earlier periods of appearance.— P. C. Z. 



t This species, which is very abundant in June on sandy plains, and can be beaten out of juniper 

 and other bushes, is not Frey's Gelechia nffinis (tegulella), but has the opposite spots almost pure 

 white ; they vary in size and distinctness, and in many specimens, which I cannot separate as a distinct 

 species, they are quite faint. My remark on umbrosella in the Isis, 1839, p. 201, that it differs from 

 coronillella by its smallness, and by the shortness of the last joint of the palpi, is not sufficient to dis- 

 tinguish it Stainton gives July as the period of appearance of the wings of 6. qfflnis. The specimens 

 taken at that time we cannot for the most part refer with complete certainty to umbrosella, because 

 they are wasted. In no umbrosella do I see the pale yellow linear connection between the two black 

 discoidal spots which the uninjured tegulella shows, but at most some whitish scales on the exterior 

 &ide of the first spot.— P. C Z,
