INSECUTOR INSCITI^ MENSTRUUS 101 



Types, male and female, No. 21545, U. S. Nat. Mus. ; "In- 

 dian Henry's," Mount Rainier National Park, Washington, 

 larvse June 13, 1917, in a mountain meadow. Old specimens 

 of this small species, Mount Rainier, Washington, August 3-4, 

 1906 (Dyar & Caudell). 



I owe the discovery of this species to Mrs. W. P. Allen, my 

 faithful nurse, and Mr. J. B. Flett, Forest Ranger in the 

 Mount Rainier National Park. Undaunted by the rain and 

 soft snow, these indefatigable people tramped up 1,300 feet 

 of altitude to Indian Henry's, only to find the whole meadow 

 deep in snow. However, they searched for a wet place, and, 

 finding it, scooped out the freezing mixture with their hands. 

 Their perseverance was rewarded by some 20 larvae of altius- 

 culus, in the first stage, which were kicking about in the water 

 under the snow. 



I would express my obligation to both Mrs. Allen and Mr. 

 Flett for their kindness in making this arduous ascent, which 

 I was prevented from undertaking personally by physical 

 disability.
