you leap. I made a photographic negative of a male and female 

 of the wonderful Arizona butterfly and printed it on platino- 

 type paper and sent it to Dr. Herman H. Behr of the California 

 Academy of Sciences. The male specimen I marked No. i 

 and the female No. 2. The following is part of Dr. Behr's 

 reply : " No. i of your drawing (photo) tallies perfectly with 

 my type (captured by the Baron Terloot de Popelaire) which 

 I still possess, but in a rather shattered condition. I have to 

 communicate to you something else. I have heard about a 

 caterpillar living in societies on a species oi A rduf?(s {Madrona). 

 These societies inhabit sacs of a paper-like substance almost 

 impervious to water. I had several of these sacs sent me, but 

 most of them contained only the exuviae of the former inhabit- 

 ants ; only in three of them were found dead chrysalids and 

 several butterflies crippled by the want of room for their de- 

 velopment. These butterflies were my N. terlootii, and the 9 

 answers to your No. 2. I do not know whether the fact is 

 generally known that the larva of A^. menapia feeds on conifers ; 

 therefore we need not be surprised to find another member of 

 the genus feeding on rather unusual food for a Pierid — the 

 Arbutus. In Java I found larva of Delias coronis on a species 

 of Capparis, analogously related to Cruciferse, like Delias to 

 Pieris. In Australia I found the larvae of two species of Delias 

 on Loxanthus preissii, a parasitic shrub on which I never would 

 have looked for Pierid larvae. ' ' 



As far as I am aware this butterfly has been unknown since 

 1869 until the present year. If Dr. Strecker had looked on 

 page 74 (No. 25) of his Synonymic Catalogue, published in 

 1878, he would have saved about ten dollars, kept out of the 

 synonymic consomme and given Dr. Barnes the pleasure of see- 

 ing his ViOxae Princeton ia in line number two. The synonymy 

 stands tiius, —
