320 THE CANADIAN ENTOMOLOGIST. 



of their observations will be differently expressed in our classifications. 

 The family " Zygaenidce" has shared the fate of disintegration with the 

 family " Bombycidse." Dr. Packard now recognizes three family groups : 

 Agaristidce, Castniidce and Zygaenidce. The sub-family Eudriiuce, as I 

 would consider it, the subject of the present notice, belongs, with the 

 sub-family A/ypiiuce, to the Agaristidce. The present sub-family seems to 

 be exclusively American ; at least I have met in literature with but one 

 extra limital form, the African genus Ovios, which may possibly belong 

 here. The general form of the perfect insect recalls that of the JVoctuidce, 

 so that Hiibner considers it one, while Boisduval proposes the genus 

 Endryas for the typical generic group and apparently recognizes its struc- 

 tural affinities to Castnia. The larva, as we now know, is closely allied 

 to that of Alypia. The genera of the Eudriina may be briefly distin- 

 guished as follows : — 



i. Structure of the male wings normal, 2. 



Structure of the male wings abnormal. Euscirrhopterus, Grt. 



2. Male antennae simple, 3. 



Male antennae pectinate. Ciris, Grt. 



3. Front smooth. Eudryas, Boisd. 

 Front horned. Copidryas, Grt. 



With regard to the geographical distribution Eudryas occurs in North 

 America (east and west coast), and in South America (Paraguay). 

 Copidryas in North America (New Mexico, Texas) and in South America.* 

 (? Buenos Ayres). Euscirrhopterus is Cuban and Ciris is from Texas. 

 With regard to the species, it is not entirely impossible that Walker's type 

 of Eudryas Stce. Johannis represents a Florida species else unknown. It 

 is pronounced by Prof. Smith to be an aberration of E. grata, and its 

 divergence from the type to have been probably produced by the " vicis- 

 situdes of the voyage." The former statement may not improbably be 

 the true solution of the matter, since so prominent an insect should have 

 been turned up by collectors in Florida ere this, one might think. But the 

 cause assigned for such an aberration I am unable to follow, or even to 

 understand. What is meant by " vicissitudes of the voyage ? " The 

 pupa (?) could not have suffered shipwreck or been washed ashore ! 

 What records are there in literature of extraordinary variations being pro- 

 duced through ordinary transportation by sea ? The chances against the 



See Papilio 3, 106. Berg's Platensis, as I understand his remark as to the front, 

 probably belongs to Copidryas.
