1^2 THE CANADIAN ENTOMOLOGIST. 



Leaving out those species not found in America north of Mexico, the 

 following is his arrangement : 



Ammalo, Walk. 



Insulata, Walk. (Halesidota), = Pareuchcetes Cadaverosa, Grote. 

 Tenera, Hiibn., = Se/urus, Boisd. 

 Eg/enensis, C'em. 



Pvgarctia. Grote. 

 Sftraguei, Grote. 

 Vivida, Grote. 

 Abdominalis, Grute. 

 E/egans, Stretch. 



Euch/Etes, Harris. 



Antica. Wa'k. (Halesidota), = Zoualis, Grote. 

 A/bicosta, Walk. ( Phragmatobia), = Seeps ifon/i is, Graef. 

 Perlevis. Grute. 

 Afurina, Stretch. 

 Bolteri, Stretch. 

 Eg/e, Dm ry. 

 Oregonensis, Stretch. 

 Pudens, H. Edw. 



It should be noted that the genus Ammalo is not regarded as being 

 at all closely related to Pvgarctia or Euchaetes, but rather very much 

 separated from them. It is treated of on pp. 82-86, while Pygarctia is 

 described on pp. 415-417, and Euchtetes on pp. 417-420. 



Whether a fuller examination of a larger series of these moths would 

 not again upset their arrangement and necessitate a new classification, the 

 future alone can tell, but I feel very strongly that far too much classifica- 

 tory work is done on very insufficient material, and after too superficial a 

 study of the material available.* 



*In Ent. News, XIII., 192, reference is made to Psychophora Fasciata, Skinner, 

 one specimen of which received by Dr. Dyar was found to agree with the N< Cluidae in 

 venation, while the next one received had the venation typical of the Geometridse, thus 

 showing the sometimes unsatisfactory nature of ihe.-e characters.
