" pale un peu jaunitre," and calls its "tubercules" not black but " bruns ;" while 

 Corydon " se diatinguera toujours assez facilement au premier coup d'oeil par sa 

 "couleur d'un vert fence, et par la petitessc de ses stigmates ;" and this is directly 

 contrary to what we saw in our examples, viz., the deep green in Adonis, and the 

 yellowish-green in Corydon, and the spiracles of the same size and form in both. —

Hybrids between Smerinthus ocellattis and S. populi. — Mr. Henry Stephenson, 

 of this town, has just reared a good brood of the liybrid between Smerinihns ocel- 

 latus and populi. I have seen a large number of them on the setting boards, and 

 very nice they are ; the markings and colours of both species coming out very 

 distinctly. Mr. Stephenson tells me the larvce also equally partook of the characters 

 of both species. — Geo. T. Porbitt, Huddersfield : September 5ik, 1874. 



Capture of Noctua sobrina. — I had the pleasure of taking at sugar, while 

 staying at Loch Rannoch this summer, two beautiful examples of Noctua sobrina. 

 By a curious coincidence, they occurred upon the same tree, a small birch about the 

 thickness of a man's arm. The fore-wings of the first specimen I captured have the 

 red ground colour much suffused with grey ; in the second they are of a purplish- 

 rosy shade. — J. B. Biackbuen, Grassmeade, Southfields, Wandsworth, S.W. :

Description of the larva of Acidalia straminata. — For the opportunity of 

 studying the history of this species, the larva of which, I believe, is hitherto un- 

 described, I am indebted to the kindness of Mr. G. B. Corbin, of Ringwood, who 

 sent me eggs with the female moth on July 23rd of last year. The eggs are rather 

 large for the size of the moth, oblong-square with the corners rounded, in colour 

 reddish-brown, — deposited loose ; they hatched on the 29th of the same month, and 

 the newly emerged larva; are long and slender,— in colour a very dark brown. They 

 were fed on Polygonum aviculare, and grew slowly until autumn, when they hiber- 

 nated, and re-commenced feeding early in March of this year. A great many of 

 them died during winter and spring, and at the end of May I had only four left. 

 These were nearly full-grown on the 18th of June, when I described them as follows : — 



Length about an inch, and ratlier slender ; head rather narrower than the second 

 segment, and deeply notclied on the crowu ; the body is rounded beneath, but rather 

 flattened above, not so conspicuously, however, as in some other Acidalia larvse ; the 

 second, third, and fourth segments are the narrowest, and are of about equal width ; 

 from the fourth they gradually become wider until the 10th, which is the widest 

 segment, is reached ; the eleventh, twelfth, and thirteenth are of about equal width, 

 but narrower than the tenth. The segments overlap each other, rendering the 

 divisions distinct, and, as in other species of the genus, each segment is conspicuously 

 ribbed transversely ; the skin has a tough appearance. 



The ground colour of the dorsal surface is pale slaty-grey ; the head is grey, 

 with the sides and the notch dividing the lobes dark brown ; medio-dorsal line very 

 narrow and pale, edged on each side in the centre of the fifth, sixth, seventh, eighth, 

 ninth, and tenth segments, with a narrow black streak, — on the other segments the 

 black edging is continuous, but narrower and much less distinct. On the middle
