 sal area of segments seven to twelve, which is white ; the ends of the segments 

 crossed by several stripes of black and fulvous, the latter very pale on seven to 

 twelve, almost fading into white ; the sides mottled with fulvous, blaclv and bluish 

 white, and Miarked by two irregular longitudinal fulvous lines, one below the 

 spiracles, the other above, this last interrupted and not always distinct ; furnished

1 The female last described is that to which I formerly <;ave the name Silrius. I suspect it am! the male are 

 seasonally-dimorphic with Ruslicus ; but these two are the only examples I have met with, and this relation- 

 ship is but conjectural. The female was bred from the larva figured in Vol. I., Plate 40, Fi;^. 8, a drawing of 

 which was sent me labeled Zephyrus, and so published. Unfortunately the male was afterwards destroyed in 

 transit to Mr. II. Edwards, and only the description remains.
