260 Short Communicatioris : — 



and spring water, three specimens of Z)5'ticus (or Dytiscus) 

 glaber, two of D. minutus, two of Notonecta glauca, and one 

 of N. striata. On the 1st of March, one specimen of Z). 

 glaber had disappeared ; and another had its head severed 

 from its body, and a Z). miniitus feeding on its entrails ; the 

 N. striata was also dead. On the 3d of March, the other, D. 

 glaber, had also disappeared : whether it had taken wing 

 during the night, I cannot determine. The N. glauca, from 

 time to time, deposited its eggs : they are about one six- 

 teenth of an inch in length, as thick as a pin, of a whitish 

 yellow colour, and so heavy that they fall to the bottom of 

 the water. — Willimn Gardiner^ jim, Dundee, April 6, 1833.

Lepidopterous Insects. — iQf Sphinx {Deilephila P) nerii. 

 (V. 154.) " a fine larva was taken in a lady's garden at Teign- 

 mouth, Devon, in August, 1832. . . . The periwinkle [Finca, 

 probably major, perhaps minor] is abundant in the garden." 

 (C Blamer, in Ent, Mag., vol. ii. p. 116.) Early in Sep- 

 tember, 1833, a lady residing in Dover captured Deilephila 

 nerii. " From the state of the specimen, which I have ex- 

 amined, it must have been very recently disclosed." {J, F, 

 Stephens, in Ent. Mag., vol. i. p. 525.) These two facts ad- 

 mirably elucidate the excellence of the arguments of W. A. B., 

 in our V. 149 — 156.; and more particularly that of those 

 touching the S. n^rii, in 154, 155. In V. 155., line 16., for 

 " birdweeds," read " bindweeds ; " the British species of 

 Convolvulus and of Calystegia are meant.] 



Deilephila linedta Stephens. ( V. 1 5 1 . ) — Of this extremely 

 rare and beautiful moth a fine individual was captured in July, 

 183 J, in the garden of T. Wells, Esq., of Bromley, Kent. 

 Its sex I have not determined ; but I am satisfied of the iden- 

 tity of the species, from a comparison of the specimen with 

 the figure in Stephens's Entomology, and with a specimen in 

 the collection of Mr. Ward of Wellclose Square. — George 

 Penny, lA.L.S. Milford Nursery, near Godalming, Surrey."} 



Colias Hijale. \_C. Edusa, Vanessa, Antiopa, and CynthiB. 

 cardui. — The appearance, in more than usual abundance, of 

 Colias Edus«, in particular seasons, is a fact well known to 

 entomologists, and has often been made the subject of remark. 

 Our other native species *, C. Hyal^, seems also to be subject 

 to the like irregularities. This is justly esteemed a very rare 

 insect ; its principal, if not its only, habitat in this country being 



* I venture to speak of the native species of the genus Collar as being 

 two only. C. Europome, it is now pretty generally admitted, has been 

 introduced into the list on more than questionable authority. C. Chry-
