it possessed. The first batch of specimens reached 

 me on January 27th, the second on February 15th; 

 after selecting a series from them for study the 

 remainder were placed in a cardboard box, and set 

 aside in a perfectly dry place until the September 

 following, when I found one of the females still alive, 

 and apparently looking none the worse for its lengthy 

 fast of eight months ! Certain of the Monophlebids 

 have been known to survive long-extended fasts, and 

 I believe the late Mr. Maskell was the first to call 

 attention to this peculiar trait in the Coccidae, but this 

 species survived a longer fast, by many months, than 

 any other known species.
