capture, its high flight and grandly rapid movements making it more of a 

 problem in that respect than most of its moisture-seeking congeners. But 

 the market value of the insect is such that, taken in connection with 

 others to be captured in that region (P. Machaonides being among them), 

 patience and hard living are sure to be well paid for. Should any col- 

 lector feel like attempting such a trip into the heart of that Vaudoux- 

 ridden region, I shall be glad to offer such suggestions as may occur to 

 me as useful to him. I shall also be glad to hear from entomologists who 

 are interested in the insect fauna of the Andean water-shed of the Amazon 

 tributaries, in Bolivia, Peru and Brazil, a region which I propose visiting 

 at an early date. Letters addressed as below will be promptly forwarded 

 to me. Eugene Murray Aaron,

ARGYNNIS EGLEIS. 



Sir, — With this I send you a piece of pine-cone with an egg of Argy fi- 

 nis Egleis on it. Yesterday, August 8th, being an unfavourable day for 

 collecting Parnassius Clodius, I went in an aimless way to find a new col- 

 lecting ground. When passing along the brov.~ of a rocky slope, I came 

 to a Pin us Murray ana tree (also called P. Contort a), and saw a female 

 A. Egleis walking over sticks and burs that were lying on the ground 

 beneath this tree. I halted for a moment to watch her, as she gave all 

 the outward signs of a desire to oviposit ; I had not to wait long, for she 

 walked to a pine-cone and, seizing it with her legs, curled her body and 

 fastened on an egg as far under the cone as she could reach. She then 

 flew about two feet and oviposited twice in succession under a stick on a 

 small stone, and on the piece of cone that I am sending you herewith. 

 As I was standing almost directly over her, she flew to my left foot and 

 oviposited several times under the shadow of my instep ; she came and 

 went several times to repeat her work. I lost a day's collecting, but felt 

 amply repaid by the novelty of the knowledge I acquired. What the 

 next female will teach me I cannot conjecture,, but trust it will be no less 

 surprising and interesting to the butterfly-loving world.
