ON THE LARVAL FORMS OF SEVERAL EXOTIC CERATOCAMPII) 



MOTHS. 



BY A. S. PACKARD, PROVIDENCE, R. I. 



The larvae here described are of 

 moths heretofore referred to the family 

 Satuniiidae. They are however mem- 

 bers of quite another group, a great 

 family or superfamily of which the 

 Ceratocampidae of the older authors 

 (Citheroniidae) Agliinae and perhaps 

 four or five otiier groups are compo- 

 nents. For example, Nudaurelia, of 

 which there are about twenty species, 

 and which were confounded with Anth- 

 eraea, until separated by Rothschikl, is, 

 though an African genus, both in its 

 iroaginal and larval characters allied to 

 our American Ceratocampids. 'I'his is 

 also the case with Gynanisa I's/'s, and 

 Urota siitflpe. I might also add that 

 after a prolonged study of the venation 

 and other characters, besides what liltle 

 we know of the larval histories, I iiave 

 come to the conclusion that many other 

 genera heretofore referred to the Saturn- 

 iidae, will have to be removed from that 

 family, and placed in this group. Ap- 

 parently none of these genera are spin- 

 ners but, like Citheronia, Eacles, Ani- 

 sota, Sphingicampa, etc., enter the earth 

 to finish their transformations, and spin 

 no cocoon. 



The group as we are now disposed to 

 limit it is divided into about si.x sub- 

 families, and comprises about thirtv five 

 genera, including the five genera {Sys- 

 sp/iinx, Sphingicampa, Aiiist>fa,-Eac/ti and 

 Citlwronia) usually referred to the Cera- 

 tocampidae. The Eurasian genus .-/^//(7 

 is a type of the subfamily Agliinic\ and 

 does not belong with the Saturniidae, 

 thougli universally referred to that family, 

 but falls into the group under consider- 

 ation. The following genera \\\\\\ the 

 six provisional groups referred to, by 

 their imaginal characters, /. e. the vena- 

 tion, antennae, etc., as well as what we 

 know of their transformations, should he 

 taken out of the Saturniidae and associ- 

 ated with the Ceratocampidae (Cither- 

 oniidae) : — 



Besides ( I ) tlie (Jitheroniidae, there is 

 3. A groin 1 '■'ipresented by Micratta- 

 cus. Lugia, IJolo'-'-Ta, and Sagana. 



3. A group (A'j;liinae) represented 

 by Arsenura, Rhescyntis, Aglia, Cer- 

 cophana, Cirina, and Usta, with a side 

 genus Polythysana. 



4. A group comprising Dysdaemonia 

 and Copiopteryx, and perhaps Titaea 

 and Loxolomia.
