and succeeded in getting several larvae past ist moult, and one past 2nd, 

 but all died. Tlie stages were very tedious, and the longest lived larva 

 reached about 40 days from egg. 1 think if I had let the eggs stay in 

 Ohio two months longer, I might have got some of the larvae to imago. 

 It will be seen then that eggs may in many cases be sent on long 

 journeys. Even the eggs of such species as hatch in 3 to 5 days may be 

 sent from Maine to Coalburgh, or from Florida^ or from Colorado. But 

 if placed in glass tubes or bottles, or in tin boxes, and sent by mail, with 

 leaves of the food plant, a journey of 6 to 12 days may be ventured on. 

 The eggs of L. Nais, from Arizona, were 12 days in the mail and the 

 larvae were in part just hatched when they reached me. I had 60 young 

 larvae of C. Eurydice come last month from San Bernardino, Cal., corked 

 up in a 2 oz. morphine bottle, which was inside a tin case. The plant, 

 Amorpha Californica, in the bottle was perfectly fresh, and the larvae, as 

 hatched, had fed on it. So Dr. Wittfeld, from Indian River, Fla., has 

 repeatedly sent me eggs in tin, which have been out 6 to 10 days. Gen- 

 erally the larvae have hatched on tlie way, but the plant has kept fresh. 

 The only trouble I remember has been with cruciferous plants, mustard, 

 radish, etc., or with passion-vine. These do not bear the journey, but 

 are apt to come decayed. But experiment has proved that such plants 

 keep well in a corked bottle, even in the hottest weather. Eggs ought 

 never to be sent in a wooden or paper box. Apart from the danger of a 

 crush in the mail bag, the plants dry up and larvae will starve. Nor 

 should cotton ever be laid with the eggs or among the leaves. The young 

 larvae get entangled in the cotton, and the leaves will dry up the sooner 

 for the presence of the cotton. There are several species of eggs of 

 Canada butterflies that I should exceedingly like to get, as Qixz.'^X.z. J-album, 

 Grapta Faunus, Argynnis Atlantis, Lye. Sciiddcrii, L. Coiiperi, Pieris 

 Virginiensis, Colias of any species, except Philodice, F. Tarqumms ; and 

 I shall be very much obliged to any person who will send me these or any 

 of them. 



Mimicry — I recently observed an interesting instance of mimicry in 

 the Phalsenid moth, Tetrads /orata Grote. While examining the 

 flowers of a bed of May apples ( Podophyllmn peltatum) I found one of 

 these white moths adhering to the stamens of a flower, its head towards 

 the center and the wings being easily mistaken for the petals. By a 

 little search another was discovered in exactly the same position.
