﻿202 THE ENTOMOLOGIST. 



arranged according to frequency, were Tceniocampa gothica, T. stabilis, 

 T. incerta (many forms being almost as grey as T. populeti), and 

 T. pulverulenta (cruda). This was my most successful night with the 

 Taeuiocampidse, for cold east and north-east breezes set in, and lasted, with 

 little intermission, till April 21st, when the catkins were over. Star- and 

 moon-light also unusually clashed with the sallows, and materially aided in 

 keeping the moths "at home." I did not see T. gracilis at all, or, I might 

 add, Triphosa dubitata, which usually shows itself on the sallow-bloom, with 

 a brilliancy and gloss certainly not suggestive of a hybernated insect. On 

 the night of March 28th, Anticlea badiata was unusually abundant with 

 us ; and Cidaria suffumata, another catkin Geometer, appeared in force on 

 April 18th. Larva?, probably of Xanthia fulvago (cerago), have been 

 common this season. I usually got one or two in the changing the catkins 

 I used as food for larvae of Agrotis ashworthii. — J. Aekle ; Chester. 



Eotherham. — As there are no sallows within ten miles of this place, I 

 have not been able to devote more than one night to them this season. The 

 following insects were observed at the catkins : — Scopelosoma satellitia, 

 Cerastis vaccinii, Tceniocampa cruda, T. gothica, T. instabilis, T. stabilis, 

 these were very abundant ; T. rubricosa, T. munda, T. populeti, fairly so ; 

 and of Pachnobia leucographa, four or five were taken. A few trees sugared 

 in the neighbourhood of the sallows were visited by T. munda, T. stabilis, 

 S. satellitia, and C. vaccinii. — J. N. Young; 85, Fitzwilliam Road, 

 Rotherham. 



North Wales. — I have worked sallows on four evenings this spring ; the 

 captures were as follows : — March 27th and 28th : two very favourable 

 evenings, T. gothica was abundant, T. stabilis and C. vaccinii fairly so ; I 

 also took a few T. pulverulenta, two T. munda, and two T. gracilis. 

 April 6th : I did not get out till after midnight, when I found two 

 T. gracilis, one T. dubitata ; with gothica, stabilis, and vaccinii, as before. 

 The above were captured near Ruthin. I spent the remainder of April at 

 Bolton, Lancashire. East winds prevailed till the end of the month. 

 April 29th was a favourable evening, although the sallows were very nearly 

 over ; I took about two dozen P. rubricosa, and a few T. gothica. — 

 J. E. R. Allen ; Ruthin, North Wales. 



Aberdeen. — So far as my experience goes, this appears to be a poor 

 district for early moths. My captures at the sallows in April were : — 

 Pachnobia rubricosa, Tceniocampa gothica, Cerastis vaccinii, and Calocampa 

 exoleta. Larentia multistrigaria, Cidaria suffumata, Diurnea fagella, were 

 common, but did not occur at the sallows. — L. G. Esson ; 6, Stafford Street, 

 Aberdeen, N.B. 



Hypsipetes sordidata. — Mr. South, in reference to Hypsipetes 

 elutata, writes (Entom. 170) of " the sallow and bilberry forms." I assume 

 the Editor to be exact in his terms, but has he been explicit enough in his 

 paragraph? He speaks of " the smaller specimens, whose larvse feed on 

 bilberry," and of " the large sallow-feeding specimens " ; and he asks his 

 readers to make certain observations. But, surely, when collecting elutata in 

 a district where both sallow and bilberry occur, one is not to put down all the 

 small specimens as the " bilberry form," and the large specimens as " the 

 sallow form." I collect elutata in a locality where both sallow and bilberry 

 occur, but could make no useful observation as to whether one " form " has 

 passed its " zenith " before the other, if size alone is to be the criterion. If 

 there be any other mode of differentiating these forms, I should be grateful
