wide as long." As a matter of fact the width is barely twice 

 the length in both hirticollis and hoppi?igi, and it is probable 

 that both authors have given the relative dimensions from a 

 vertical view point, in which case there would be considerable 

 fore-shortening. I take pleasure in dedicating this fine species 

 to friend Hopping, whose explorations in the Californian 

 Sierras have brought to light not a few new and interesting 

 species. 



Notes on Moths. 

 By Caroline Gray Soule. 



At one time there was some discussion of the cause of dif- 

 ference in the forms of cocoons of Attacus cecropia, and some 

 very positive statement that the baggy cocoon was always 

 found low on the shrub or tree and in damp lowland places. 



Last September I found three huge cecropia larvae feeding on 

 red-berried elder by the roadside, in a dry, sunny place. They 

 were so large that I took them, put them in a large box with 

 twigs fastened vertically and horizontally, and the larvae spun 

 the next day. 



One made a normal, slender cocoon on a horizontal twig : 

 another made a very baggy cocoon on a vertical twig ; the 

 third made a rather baggy one, of a green color except on one 

 side where the normal brown predominated. This cocoon was 

 on a horizontal twig, and against the side of the box. 



On June 9th were laid eggs of Hemileuca budleyi from moths 

 descended from two pairs of moths received in 1903. 



Their egg-period was 36 days ; 1st stage, 7 days ; 2d stage, 

 5 days ; 3rd stage, 8 days ; 4th stage, 7 days ; 5th stage, 10 

 days ; 6th stage, 10 days ; 7th stage, 16 days, making 63 days 

 from egg to cocoon, and a sixth moult, which had not occurred 

 in any former brood. Although " bred in " for three genera- 

 tions they were very large, fine specimens, but very slow in all 

 their stages. One correspondent, to whom I had sent eggs, 

 wrote that his brood left the wild cherry tree on which he had 

 placed them, and marched eight or ten feet to a small apple 

 tree where he found them feeding and thriving.
