*) Letters from a fellow-student inform nie that in my Tara che anpusti- 

 pennis from Colorado the costal vein is united to the subcostal on hindwings 

 as far as in the magority of Arctians. This distinction between Arctiidae 

 and Agrotidae will probably then not hold; it may be the weighticst 

 distinction will be offered in larval structure. I have long been of opinion 

 that angustipennis and probably another of my species were not congeneric 

 with aprica and the majority of our forma of Tarache. Por anguetipennis 

 I propose the genus Therasea, differing from Cerathosia in frontal structure, 

 but otherwise seemingly related. From the utter want of material to carry 

 out Ihese studies, 1 leave the type in Tarache where it will be naturally 

 looked for. According to Dr. Packard's studies on the larva, Cerathosia 

 belongs to this family and neither to the Arctiinae or my subfamily 

 Cydosiinae, to which latter group Mr. Smith has more recently referred 

 it after my correction of bis original observatioos on the structure of the moth.
