LEPIDOPTERA HETEROCERA. 927 



Male, Ochraceous, slender, pale beneath. Head white about 

 the eyes. Palpi fawn-colour, porrect, broad, acute, pure white be- 

 neath, as is also the fore part of the pectus. Abdomen extending 

 for about one-third of its length beyond the hind wings. Fore legs 

 with brown bands. Wings pale luteous, broadly purplish along the 

 exterior border; lines brown. Fore wings acute, purplish along the 

 costa; exterior line much bent; orbicular and reniform marks brown, 

 the latter lunulate. Hind wings with the interior line obsolete ; 

 discal mark hardly apparent. Length of the body 4 lines ; of the 

 wings 8 lines. 



This species much resembles S. Largalis, but may be distin- 

 guished by its longer palpi ; its more stout antennae, and by the 

 exterior line of the fore wings, which is slightly curved inward, 

 whereas that of S. Largalis is curved outward.

 cas longe superans, fasciculo apicali albo bivittato ; aim sub- 

 cuprea, apud discum subpur pur ece, fimbria basiet extusalba ; 

 antica valde elongate, fascia opalina inleriore subfracta costam 

 non attingente, puncto contiguo maculaque exteriore oblonga 

 transversa opalinis ; posticce fascia postice attenuata slrigaque 

 postica opalinis. 



Male. Brown, white beneath. Palpi beneath and pectus snow- 

 white. Abdomen extending far beyond the hind wings, with a white 

 apical tuft, which has a black stripe on each side. Wings with a 

 cupreous tinge, more purple in the disk ; fringe white exteriorly and 

 at the base. Fore wings much elongated, with an interior opaline 

 white band, which is somewhat dislocated in front, and does not 

 extend to the costa ; it is accompanied by a white point on its outer 

 side, and by a more exterior oblong transverse opaline white spot. 

 Hind wings with an opaline band, which corresponds to the band of 

 the fore wings, and is attenuated hindward, where it is accompanied 

 by a white streak. Length of the body 7 lines ; of the wings 16 

 lines. 



This and the following species are nearly allied to D. orbalis 

 and to D. Tagesalis.
