DORYCAMPA* REGALIS. 



PLATE XVIII. 



Bombyx regalis, Fabr. — Phal. regia, Abbot and Smith, Lepid. 

 Georg., ii. pi. 61. — Cerocampa regalis, Kirby. 



This moth is among the largest of the nocturnal 

 Lepidoptera of America, and in many respects a 

 remarkable one. From the thickness of the body 

 and general aspect it is not unlike a gigantic Cossus. 

 The figure on the annexed plate is that of a female, 

 somewhat reduced in size. The antennae of the male 

 are pectinated, those of the female setaceous. The 

 wings are rounded on their external margin, but 

 considerably more so in the female than the male. 

 The ground colour of the upper wings is greyish- 

 brown, of a deeper or lighter tint in different indi- 

 viduals, with a series of large yellow patches rather 

 behind the middle, others of smaller size at the base, 

 and two or three towards the centre ; all the ner- 

 vures are accompanied with a regular reddish stripe. 

 The under wings are reddish-brown, the nervures 

 red, a few yellow clouds anteriorly, an indistinct 

 yellow band beyond the middle, and a series of 

 black angular spots towards the hinder extremity. 

 Head yellow; thorax reddish-brown, with a band 

 in front, two diverging dorsal stripes, and two spots 

 * A«£t/, hasta, and *s«^<t», eruca.
