656 [December 



regularly ridged transversely, with a medial impressed line having mo- 

 derately elevated margins — its trunk raised by one-half its diameter 

 from the breast, the tip applied to the breast and slightly bulbous ; the 

 buried portion of the tongue-case smooth, extending to the tips of the 

 wing-cases, which are also smooth. Anterior leg-case with a prominence 

 over the femur. First segment with a smooth dorsal spot, from which 

 wrinkles radiate. Second segment moderately rounded, with inter- 

 rupted transverse wrinkles dorsally. Third segment with a dark brown 

 central transverse fold, interrupted dorsally. Central segments broader 

 than the thoracic region, moderately punctulated, with dorsal wrinkles 

 and depressions. Eleventh segment with a small dursal protuberance. 

 Terminal segment quite tapering. Spine short, blunt, wrinkled and 

 bifid. 1 S . 



The Imago frequently enters houses in July, attracted by lights. I 

 have often captured it at twilight, taking its food from the Italian Ho- 

 neysuckle (^Lo)n'cera Capri/olimn), upon a couple of vines of which, a 

 young lad took, in one evening, ten or twelve, without a net, by simply 

 throwing over them a handkerchief, while a larger number escaped 

 from his rude method of collecting. 



A. gentleman who had pinned a fresh $ of this species upon a fence, 

 where it was forgotten at the time, the following morning found a % 

 in copulation with it. A second one, exposed during the night as an 

 experiment, also drew a mate, which was captured in the morning. 

 Pterec/oii inscriptum Harris, Thi/rcus Abhutii Swainson, Darapsa 

 Myron Cramer, and Smerinthus tjeminatus Say, from the breeding cage, 

 are known to have been fertilized in this manner, and broods of the 

 imago reared from their eggs. 



It is probable that many, if not all of the Sphinges, when newly 

 emerged, possess the faculty, in common with the Saturnians, although 

 perhaps in a lesser degree, of attracting the S ; and as several of the 

 species have been known to deposit eggs after being pinned, an excel- 

 lent opportunity is thus aiforded of becoming acquainted with their 

 larvae, of obtaining bred specimens for our collections always so highly 

 prized, and of ensuring a number of duplicates for exchange. 



When the $ is of such rarity that its possessor would be unwilling 

 to subject it to the risk of injury from fluttering during a night's ex- 

 posure, the precaution may be adopted of fastening the wings together
