this insect on a species of Salix ; they were then nearly full 

 fed, and all became pupae in less than a fortnight — the last 

 change occurring on the 13th August. I subsequently found 

 two pupae spun up among the leaves of the food-plant; they 

 remained about three weeks in pupa, and, with one exception, 

 emerged as perfect insects. I observed that the larvae fed 

 upon the light-green close-clinging leaves (near the top of 

 the twig), which at a little distance they much resemble. 

 Among other larvae found on the same plants were those of 

 Dicraiiura vinula ; in changing to pupa those taken by me 

 went under the earth in the breeding cage, making their 

 cocoons of grains of soil. — L. Dunbar ; Wick, Caithness. 



Identity of Heliothis scutosa, &c. — In the 'Entomo- 

 logist' (Entom. X. 34) the Editor asks whether anyone has 

 confirmed the identity of Heliothis scutosa, and other rare 

 species, reported by Mr. W. H. Thornthwaite as captured 

 near Norwich. To this question the latter gentleman asks 

 me to reply. A few months ago Mr. Thornthwaite's 

 announcement of the capture of these rarities came under 

 my notice, and as my name was mentioned in the communi- 

 cation I, after some hesitation, wrote to him for further 

 information, conveying, 1 fear, rather unpleasantly, my 

 extreme scepticism about their identity. However, after his 

 very courteous explanation of his mode of working, and the 

 particulars of their capture, I was satisfied of the bond fides 

 of the captures, made, as they were, in his absence, by 

 friends totally unaware of their value, but working under his 

 directions, and sending him up the specimens fresh and 

 unset. The identity of the species in the case of Heliothis 

 scutosa was settled by Mr. Thornthwaite's kindly sending me 

 a specimen which had been taken in the same place last 

 summer. It is abundantly distinct from our other species of 

 Heliothis, being whitish, with the bands and large distinct 

 stigmata dark gray. The gray fascia, before the dark marginal 

 band of the hind wings, is also very distinct. After seeing it 

 one feels astonished that any variety of H. dipsacea could 

 ever be mistaken for it. 1 have not seen Mr. Thornthwaite's 

 Noctua fiammatra, but hear from him that it has a black 

 collar, wliich seems conclusive. There is no doubt of the 

 identity of his Heliothis armigera, which I have seen. —
