small patch of red. Var. 3. — No triangular patches of yellow or brown &c. along the 

 sides, not so thickly spotted with yellow as the others : dorsal line very slender, and 

 in some individuals entirely missing, its place being left in black : the oval lateral 

 yellow patches are often tinged with pink, especially the lower ones, which are some- 

 times quite pink : the head, generally retains the two black patches, which the others 

 only have when young : the abdomen and prolegs are generally quite black, and the 

 thoracic legs are generally tipped with black, and often entirely of that colour. This 

 handsome larva grows to nearly three inches in length, and is found from the middle 

 of June to the end of October, and invariably on Euphorbia Cyparissias, or Cypress 

 spurge, which grows on dry banks. I have found as many as 150 or 200 larvae in one 

 spot, often fewer, but never solitary. They gnaw the lower leaves of this spurge from 

 their apex to their base, and eat very rapidly. It is extremely common in Switzer- 

 land ; the little children of that country all know the larva by the name of Chenille de 

 Tithymale, and have often brought me their caps and hats full of them. The next 

 Deilephila that comes in order in the ' Index Methodicus ' of Dr. Boisduval, is D. 

 Esulae. This, according to Mr. Anderregg, is the scarcest of all the European Deile- 

 philae. D. Galii I have once seen in the larva state ; it was found on the common 

 vine, on which it fed, as well as on Galium verum and Mollugo. It is seldom met 

 with in the canton of Vaud ; I met with it in the neighbourhood of Lausanne. The 

 following is its description. Caterpillar smooth, elongated, attenuated anteriorly, of a 

 fine olive-green colour, more or less speckled with yellowish green ; an interrupted dor- 

 sal line of dull pink, and on either side one of bright green, meeting the dorsal one at 

 the head ; the lower half of the body and abdomen pale yellowish green; a series of 

 large pyriform patches of a yellow colour, bordered by black, with a brown-red spot in 

 the middle of each, these spots lie on the dorsal lines which meet on either side of the 

 horn ; those on the middle segments are the brightest and largest ; a lateral line of 

 yellow, having on the segments a pinkish red speck, on which are the stigmata; a pale 

 yellow ventral line : legs yellowish ; thoracic legs tipped with dark brown : head slate- 

 colour, with the mandibles black : labrum green: palpi yellow tipped with brown: 

 escutcheon fine green, with a slate-coloured semi-oval patch on it : anus with a slate- 

 coloured patch above : horn brown, tipped and granulated with black : stigmata light 

 orange bordered with black. I have also had much pleasure in rearing the larva? of 

 D. lineata in the canton of Vaud, at Lausanne, where it is reckoned a great rarity. It 

 was found on the 19th of June, 1846, in a vineyard near Clermont, on Les Mousquines 

 (Lausanne), and fed on Galium Mollugo. The caterpillar is smooth, elongated ante- 

 riorly ; ground colour apple-green, more or less speckled with yellowish ; an olive-co- 

 loured dorsal-line, dilated into a triangle on the first segment ; lower half of the body 

 and all the abdomen of a yellowish uniform olive colour; a series of large oval patches 

 of shining light yellow on either side of the dorsal line, two on each segment, of which 

 those of the middle segments are the largest, brightest and most round ; each of these 

 patches is circled with black ; a brownish interrupted lateral line, on which are placed 

 the stigmata : abdomen yellowish olive, with a darker ventral line : all the legs are of 

 the same colour as the abdomen ; the thoracic legs tipped with shining brown : head 

 greenish olive, with a triangular brownish patch over the maudibles ; mandibles and 

 lower part of the head black : horn of a yellowish green colour granulated and tipped 

 with black: stigmata pale orange surrounded by black: a pale lateral line between the 

 dorsal and lower lateral line. — //. L. de la Chaumette ; Church St., Stoke Newington,
