AND THEIR TUANSFORMATIONS. 15 



Sphinx Cingulata, Fabr., (Sph. Druraji, Donovan, Brit. Ins. Vol. 14, pi. 4(1!) ; Curtis, Stephens ; Wood, 

 Ind. Ent. t. 53, f. 24, figured by Abbot and Smith under the name of Convolvuli var.), is an American species, 

 closely allied to the Convolvulus Hawk-moth, and has been several times captured alive in the neighbourhood 

 of London. Its wings are clouded with ashy and brown, the fore ones with two central small stripes, and several 

 lines of black, the posterior rosy, with three black bands, the abdomen ashy, with alternate black and rosy 

 lateral bars. The expansion of the wings is from nearly three to nearly three and a half inches. The 

 caterpillar feeds on the Convolvulus Batatas. 



Sphinx Carolina, Linn:eus (Haworth ; Curtis, Brit. Entom. 5, pi. 19.5 ; Wood, Ind. Ent. t. 5.3, f. 22), 

 is another North American species, which has been several times taken in this country. Its wings are varied 

 with brown and ashy, and with several slender zig-zag streaks ; the hind wings pale brown, with three black 

 bars ; the middle one formed of two subconfluent ones ; and the outer one acutely dentate ; the abdomen brown, 

 with five or six large orange spots on each side, edged with brown. The expansion of the wings is four and two- 

 third inches. The caterpillar is green, with white oblique stripes on the sides, and a pink tail. It feeds on the 

 tobacco and potatoe. 



Sphi.\x tiUiNQUE-MACnLATUs, Ilawortli (Curtis; Wood, Ind. Ent. t. 53, f. 23; Spk. Carolina, Donov., XI. 

 pi. 361), is another North American species, which has not only been captured in the perfect state in this 

 country, but has been reared from the caterpillar, found near Leeds ; its wings are clouded with ashy and brown ; 

 the posterior having four bands ; the two middle ones confluent ; and tlic outer one entire ; the abdomen with 

 four large orange spots on each side, margined with brown. The expansion of the wings is four inches and 

 two-thirds. 



Sphinx plebeia, described by Fabricius as a native of the islands of America, and by Dr. Harris as inhabiting 

 the southern parts of the United States, has also been introduced as a doubtful native species, several specimens 

 having been found in old English collections, where it is supposed they were placed by mistake for Sph. 

 Pinastri : the wings are grey, with a central white s])ot, and several rather indistinct black lines ; the hind wings 

 light brown, with darker bands; the abdomen grey, with a black dorsal line; the sides white, margined 

 with black ; the expansion of the wings is rather more than three inches. It is figured by Wood, Ind. Ent., 

 tab. 53, tig. 25. 



Sphinx pcecila, Stephens (lUustr. H. 1, 122 ; Wood, Ind. Ent. tab. 53, fig. 26), is another species, of which 

 a single specimen is contained in the collection of the Zoological Society, lately belonging to N. A. Vigors, Esq., 

 obtained from Sir, Wilkins' cabinet, in which it was also placed as Sph. Pinastri. It is two and three-quarter 

 inches in the expansion of the fore wings, which are rather acute, hoary, clouded with brown, a white spot on 

 the disc, and several longitudinal and oblique black lines ; the hind wings brown, with a broad pale fascia, and 

 the sides of the abdomen spotted with black. Mr. Stephens does not hesitate to regard it as an exotic insect.
