HETEROCERA AMERICANA. 



Bv Richard H. Stretch, E.M., 



West Seattle, Wash. 



A quarter of a century ago the writer had in preparation a mono- 

 graph of the Bombycidae of North America, intended as an enlarge- 

 ment and completion of his Zygaenidae and Bombycidae of North 

 America, published in 1S72. Various causes prevented the comple- 

 tion of the work at that time, but the plates were nearly all prepared 

 and in part printed. So much work has been done on the group in 

 the interim that the " Heterocera Americana " as prepared is obso- 

 lete ; but I have turned the plates over to the editor of this Journal, 

 who thinks them worthy to present to our readers. The plates illus- 

 trate the xVrctiidas and their allies. I wish to express my acknowledge- 

 ments to the gentlemen who assisted me with material and otherwise 

 in former years while the work was in preparation, Messrs. Henry Ed- 

 wards, B. Neumoegen, E. L. Graef, F. Tepper and others.
