[February,. 



species as the Argynnids, Pyrameis cardui or Danais archippits , 

 This season has proven an unusually productive one, and fully 

 twice the number of butterflies were on the wing this year than 

 appeared in either 1891 or 1892. 



Our climate and soil are so dry that no agriculture is successful 

 without irrigation, and I attribute this season's productiveness 

 in the Lepidoptera of this immediate vicinity to systems of artifi- 

 cial irrigation which have been in successful operation here only 

 the last two seasons, and no doubt all insect life so dependent 

 upon vegetation, will steadily increase as the amount and variety 

 of plant-life is multiplied year by year by the introduction of 

 agriculture under our irrigation systems along the Tongue and 

 Yellowstone River bottoms.
