According to Abbot the caterpillar is pale green, with white lateral oblique stripes, and a pink tail. It is said to feed on the potato, tobacco, red pepper (Capsicum?), &c. One of these caterpillars, observed by Abbot, went into the ground on the 19th of June, and came out on the 15th of July; whilst another went in on the 8th of July, and came out {48}on the 1st of August. The caterpillar is stated by the same author to be very destructive in plantations of tobacco, the cultivators being obliged to pick them carefully off the young plants. The chrysalis is of a chesnut colour, with a long nearly straight tongue case, extending to the middle of the breast, and clubbed at the end. The moth is generally seen in an evening, sucking the James-town weed and gourd blossoms, and continues breeding all the summer; the moth is common in the West Indies, as well as in Georgia and Carolina. Dr. Brown says it is called the musquito hawk, from its appearing at that time of the evening when those insects abound, and being vulgarly but erroneously supposed to prey upon them. _Abbot and Smith, loc. cit._ Specimens of this American insect have from time to time been captured in this country. "It unquestionably cannot," however observes Mr. Stephens, "be considered as indigenous, and ought to be rigidly excluded from our cabinets; otherwise the most perplexing consequences must inevitably arise, to the total confusion of our inquiries into the geographical distribution of insects. If this be admitted, as well might 'the noble monarch of the forest,' because a captive lioness which had escaped from her prison was retaken on Salisbury Plain." SYNTOMIS PHEGEA. Plate XXV. fig. 2.
