the southern rim of Grande Ronde Valley to Ladd Canyon, thence drops 

 into the Valley west of Hot Lake, and along the base of the rim to Le 

 Grande where it crosses the mountains. The old wagon road from Le 

 Grande through Meacham to Cayuse now marks this part of the trail. 

 In 1917, the trail west of Fort Hall was traced. It passed along Big 

 Butte to Big Lost River, thence up Big Lost to the vicinity of Arco, 

 Idaho, thence west to Antelope Creek and down the creek to Big Lost 

 River again, thence up Big Lost, the East Fork, and Wildhorse Creek 

 into Thornburg's Ravine. No pass being located here the party re- 

 turned the next morning to the north fork and crossed the Sawtooth 

 Mountains by the only pass in this vicinity, the pass now used by the 

 wagon road. M. W. Lyon, Jr., Recording Secretary. 



ENTOMOLOGICAL SOCIETY OF WASHINGTON 



The 313th meeting of the Society was held at the Cosmos Club, 

 May 2, 1918. The meeting was called to order by President Sasscer, 

 with thirty-two members and three visitors present. 



The following names were favorably acted upon for membership: 

 Mr. C. A.Weigel and Mr. Wm. A. Hoffman, both of the Bureau of 

 Entomology. 



The regular program was as follows : 



W. D. Pierce: Medical entomology, a vital factor in the prosecution 6f 

 the war. This paper, which will be published in the Proceedings of the 

 Society, deals with insects as disseminators of diseases of man and ani- 

 mals with special reference to the problems of army-camp sanitation.' 

 Following the reading of Dr. Pierce's paper the matter of the relation of 

 entomology and entomologists to the health of our army was interest- 

 ingly discussed by Dr. L. O. Howard and Mr. A. N. Caudell of the 

 Bureau of Entomology, and Major Alfred M. Lund, Captain Robert 

 H. Brown, and Lieutenant E. H. Gibson of the army Sanitary Corps. 

 The remarks of these army officers were especially appreciated, de- 

 scribing, as they did, actual experience in the practical handling of the 

 perplexing problems of sanitary engineering in its entomological phases. 



J. A. Nelson: A microcephalic drone bee. This interesting descrip- 

 tion of an extraordinary aberrant drone bee will be published in the 

 Society Proceedings. 



R. A. Cushman: A convenient method of handling large numbers of 

 individuals in life-history studies. Mr. Cushman described and illus- 

 trated the decimal system of keeping records of rearing experiments. 

 His remarks were discussed by Messrs. Hyslop, Pierce, Caudell, and 



ROHWER. 



H. G. Barber: The genus PlitUhisus Latreille in the United States. 

 Read by title. A. B. Gahan, Recording Secretary.
