S26 * ZYG^NID^ AND BOMBYCIDJE 



gin of 4th median ; a triangular submarginal spot in tlie same inter- 

 space ; six marginal more or less triangular streaks in the interspaces, 

 two being near the apex, one at the anal angle, and the other three in 

 the interspaces of the median nervules ; of these the longest are the 

 anal spot, and the third from the anal angle. There are also two simi- 

 lar spots near the costa midway between the apex and the spot on the 

 discal vein ; a long streak just above the submedian reaching from the 

 base nearly to the outer margin, and a short basal stjeak below the 

 same vein. 



Secondaries whitish, clothed with pink hairs on the basal portion, 

 with a distinct very narrow vermillion marginal band from the apex 

 nearly to anal angle, and marked as follows with dusky black. Two 

 geminate marginal spots on apical half of outer margin ; a submar- 

 ginal row of three spots, the first of which lies between the geminate 

 spots, the second and largest on 4th median, the third on the sub- 

 median nervule. Also a spot on the discal vein, and some blackish 

 markings on the costa. 



Beneath the wings are whitish. On the primaries the spots are re- 

 produced but the discal area is entirely black, while the costa is ver- 

 million, as is also the outer margin very narrowly, and the top of the 

 veins especially towards the apex. Secondaries very much as above 

 only wanting the pink basal hairs. 



? . — Similar to male. This species varies much in the ground 

 color of the wings, being often dirty white and all intermediate grada- 

 tions to flesh color ; and many of the spots, especially on the second- 

 aries are frequently obsolete, as will be seen in the figure of the ? . 

 The latter is drawn from a Texan, and that of the 3 from a New 

 York specimen.
