erichsonii var. longiclavus Lee, many Bryaxis conjuncta Lee, 

 and Bry. albionica Mots, in rubbish under logs at Cceur d' Alene, 

 Idaho. Tychus cognatus and Batrisus zephyrinus Casey (which 

 runs in collections as albionictis Aub6) occurs in moss at Victoria, 

 Vane. L ; the latter species also at Tacoma. 



Batrisus monticola Casey came to hand only once in the Cas- 

 cade Mountains, Yakima Co., Wash., where Bry. albionica was 

 also taken. A single $ of Bry. albionica also occurred at Vic- 

 toria. At Portland, Oreg., I got a specimen oi Faronus cavifrons 

 Casey under bark. Bry. ftindata is found at the Spokane Falls 

 late in July, under logs, and in the Rocky Mountains at MuUan, 

 Mon., I took a beautiful example of Tyrus corticinus Casey. 



Mycetina hornii occnvs occasionally under bark throughout the 

 Northwest, but I found in one case a colony of over severity-five 

 individuals under a single log in a burnt district of the pine forests 

 covering the Cceur d' Alene region. Byrrhidae seems to prefer 

 burnt logs for protection, as they were always more numerous 

 where the timber had been charred by fires. Calochromus di- 

 midiaia has the same habit. 



In a swamp at Cceur d' Alene I found Aphodius occideiitalis in 

 unlimited numbers in little ditches which ran through the soft 

 earth. They were there by thousands, dead and living, a half 

 hour's work supplying me with above seven hundred of them. 

 The beetles were burrowing at random in the mud, which was 

 apparently rich enough for them to live and luxuriate in, full of 

 decaying vegetable matter. Toads had been attracted to the feast 

 in numbers, and, to judge from the quantity of wing covers in 

 their excrement, had made the most of their opportunity. 



Amphicoma canina and A. rathvoni are day fliers, and may be 

 found flying in the hot sun during the early part of July, fre- 

 quenting the flowers of the ' ' Yarrow, ' ' which grows abundantly 

 near Tacoma, where I made my observations. I do not know if 

 the occurrence of Cremastochilus under bark has ever been re- 

 ported. I took a few of them in such a situation at Cceur d' Alene, 

 but they were in the company of their hosts — ants. I have called 

 the species pilosicollis Horn, but there may be some little doubt 

 as to the correctness of the determination. 



The electric lights of Spokane Falls attract great numbers of 

 Ergates spiculatus and Prionus calif ornicus , so I made it my 

 business to go around every night to pick them up. They come
