Of the twenty-three eggs and three small larvae collected 

 May the ist, sixteen were brought to pupation, the chrysalids 

 being of the following colors and numbers : 5 green, eight 

 light brown, 2 red and i yellow. The proportional number 

 of green ones is much greater in the first (spring) brood 

 than in the later ones. 



Throughout May and June other eggs and larvae were 

 collected, and the first marccllus imagoes from chrysalids were 

 given June 7th. Each day thereafter to the I7th, gave a few 

 butterflies. Stragglers continued to emerge through July, per- 

 haps half a dozen in all. Then there seemed to be an end 

 to the "hatching." 



On September ist another marcellus imago was found in the 

 box. 



There were left over sixteen pupae from the May and June 

 eggs and these are at this writing giving winter forms of 



imagoes.

Preparing Lepidoptera for the cabinet in short order. 

 H. H. BREHME, Newark, N. J. 



It has been the custom of collectors of Lepidoptera up 

 to the present time to spread their specimens and let them 

 remain on the spreading boards all the way from two to six 

 weeks. 



First of all, a collector needs a lot of spreading boards 

 and plenty of space to store them, which is inconvenient to 

 many if not all collectors of Lepidoptera. This is not all: 

 many of the specimens get destroyed while on the boards, 

 losing the bodies either by mice or by destructive insects. 



I also found, as other collectors undoubtedly do, that no 

 matter how long a once papered specimen remains on the 

 board after being relaxed, it will always spring back again in 

 a short time ; and to get it in proper shape it will have to be 

 relaxed again, making double the work. I have been 

 making experiments for three years in baking the specimens 

 on the board and find it a great success. 



I am now glad to let the Lepidopterists know all about
