LETTER OF TRANSMITTAL 



Smithsonian Institution, 



United States National Museum, 

 Washington^ March 17, 1890. 

 Prof. G. Brown Goode, 



Assistant Secretari/ Syniihsonian Institutioii, 



In charge of National Museum: 

 Sir: I have the honor to transmit the accompanying paper, which 

 was largely prepared by Professor Smith while associated with me, and 

 was, in fact, begun with the intention of i)ublishiug a coujoijit and 

 complete monograph. My time having been too much occupied other- 

 wise, the original plan was abandoned, and I turned the matter all 

 over to him when he left the Museum with the understanding that he 

 would finish individually the synoptic and descriptive parts. The result 

 is the present paper, and I strongly recommend that it be published as 

 a Bulletin of the Museum. 

 Sincerely yours, 



C. Y. ElLEY, 



Curator of Insects.
