followed by much waved parallel lines of dark ashen and light gray four 

 of each, the lighter spaces slightly the wider. Then beginning % dis- 

 tance to apex a broad dark ashen band narrowing much posteriori}- with 

 indistinct lighter bands within; then two waved bands, first one light 

 gray, second one dark waved, parallel with margin; then a light line, then 

 a marginal brown ashen band. Fringes alternating light and and dark 

 gray. A faint russet yellow tinge sub-basally and in sub-marginal bands 

 beyond discal spot. 



Hind wings light at base with three ashen bands, the inner faint, the 

 outer distinct and marginal. 



Beneath almost uniform light ashen.

Habits of the larva of Rhodophora Alaria 

 florida, Qvm. 



Man}- have long known that the larva of Rhodophora florida, feeds on 

 the evening primrose, but few have succeeded in finding it, common as 

 it is, and it has escaped even experienced collectors searching for it. They 

 have all construed the expression "feeds on the evening primrose!', to 

 mean the leaves of that plant, while as a matter of fact our larva lives on, 

 and partially in the buds. The modus operandi is as follows: A small hole, 

 of a diameter barely equalling that of the larva is cut near the tip of the 

 bud, and the larva then feeds downward, exposing itself less as it gets to 

 the lower part of the bud. When one is emptied another is attacked, and 

 so on until the larva is full fed. If it happens that the buds are all gone 

 before that time, it still avoids the leaves, but attacks the seed capsules, 

 which much resemble the buds, both iu size and form, and leaves the em- 

 1 pty capsule with a small hole near the tip, to explain matters to the in- 

 itiated. The color of the larva is green like the bud it feeds on and with 

 the same velvety appearance: the part outside of the bud or sded capsule 

 is always extended longitudinally along it, so that it is not readily preceived. 

 They are easily raised, and although I have been signally unsuccessful my- 

 self it was not because of any difficulty with the lame, but because I neg- 

 lected the pupae. The imagines are found early in the morning in the 

 flowers of the preceeding evening.
