larvae and eggs that I could find on Triosteum and transplanted 

 to my garden a lot of the plant. Some of these larvae pupated 

 by the iyth of June, attaching together leaves and debris on the 

 surface of the ground, the pupa being enclosed in a loose cocoon 

 of purplish brown silk ; the others all spun up by the 24th, and 

 between July 5th and i8th. All emerged ; most of them were 

 the typical serrate-inner-marginal Hcmaris diffinis, two or three 

 had the whitish-yellow coloring of tennis, but the wings of 

 diffinis, and one was the form ccthra. I had taken these 

 pupae South with me, and so was forced to kill the imagines, 

 as I had no chance to tie out a female, but on my return to 

 Virginia I visited a patch of Triosteum, and after some search 

 found a female H. dijfinis flying in and among the plants, ovi- 

 positing. I gathered what eggs I saw her lay and then cap- 

 tured her, getting altogether about forty eggs. This was oil 

 August ist, '99. This female is in every way a typical H. 

 diffinis, and is Fig. i in the accompanying plate. 



I kept these eggs carefully to themselves. The larvae differed 

 in no particular from any of the other larvae I had before obtained 

 from the Triosteum. By August 2yth all had pupated. I kept 

 these pupae in the same breeding cage, all to themselves, marking 

 the case ' ' Pupae from Eggs of diffinis, ' ' so as to avoid any mis- 

 take. On May lyth, 1900, the imagines commenced to emerge, 

 and most of them I succeeded in killing before they had a chance 

 to flutter, thus preserving the smoky appearance due to the cov- 

 ering of scales on the vitreous spaces. All were typical H, tennis, 

 those that were scale-covered being Strecker's fumosa. It was 

 interesting to notice how quickly the wings became clear if the 

 moth fluttered. One buzz, and presto ! H. fumosa became 

 tennis, with the clear vitreous spaces. In the plate Figs. 2 

 to 8 inclusive are specimens selected from this brood, from eggs 

 of diffinis. 



I selected two females, each being as true tennis as I could 

 find in the brood, and tied them out. From one I had no re- 

 sults, but from the other I obtained sixty odd eggs from which 

 I obtained fifty-nine larvae. Descriptions of eggs and larval 

 change are appended to this article. These eggs were laid on 

 June ist and commenced hatching on the 6th ; the moults were
