would pronounce it to be that species, I naturally became very much 

 interested. 



I carried the moth with me to Washington, where it was carefully 

 examined by Dr. Dyar, who pronounced that it belonged to the genus 

 Pygarctia, as it had an accessory cell. 



Before venturing to describe it, I determined to obtain as many 

 of the species of the group as possible, and through the kindness of Mrs. 

 Slosson was able to add a specimen of Pygarctia Abdoniinalis to my 

 collection, and obtained by purchase several other species. 



In Neumoegen and Dyar's " Preliminary Revision of the Bombyces 

 of America north of Mexico," published in 1S03-94*, all the moths for 

 which the name Euchaetes had been used were embraced in Hiibner's 

 genus Cycnia, which that author had also used for Hyphantria Cutiea, 

 but in September, 1897, Dr. Dyar published in the Canadian 

 Entomologist " A Generic Revision of the Hipocritidse (Arctiidae)," in 

 which the moths in question were divided into three genera, Cycnia 

 characterized as having " veins 7 to 10 of primaries stalked," Pygarctia 

 with "accessory cell present," and EuchaHes "accessory cell absent/' 

 and in the list of genera and species these moths were distributed 

 among these three genera as follows : 



Cycnia, Hiibn. scepsifonnis, Graef. 



tenera, Hubn. aibicosta, \\*alk. 



sciurus, Boisd. Euch.ctes, Harris.

When, however, I came to study the venation for myself, I got into 

 difficulties at once, as I found that while Tenera had the veins 7-ic 

 stalked as described, Abilominalis had no accessory cell, while Eg/e had 

 it. I therefore immediately wrote to Dr. Dyar, who admitted that he had
