 of Eumacus have been discussed by Mr. Samuel 11. Scudder,* but he 

 hardly refers to the life history of the species. Another description 

 of the earlier stages seems to be given by F. Poey in his work on the 

 Lepidoi)tera of Cuba, but I have not been able to consult the work. 

 It is not quoted by Scudder but may contain a full account of the life

 to place on record the following short observations made independently 

 last year during a stay at Cocoanut Grove, Dade County, Fla.

Tlie species is so frequent and so tame in the pine woods between the

 in tlie world to gather some observations on its natural history. Its

 be generally known that it furnishes almost the only means of subsist-
