G. The American Species ok Stknoisothkl-s. 



I have 1 1 1 ) n i< rous specimens of Stenobothrus from weal of the Missis- 

 sippi and east of the Siena Nevadas, including Dallas Co., Iowa (All 



Nebraska (Dodge), Colorado, 5500' and 8 1' (Morrison). Ft Collins. 



Col. (Baker), Morris Ranch, Larimer Co., Col, 8500' (Baker), Garland 

 Col-.Aug. 28-29 (Scudder), Salt Lake Valley. Utah, Aug. 1-1 (Scudder), 

 Spring Lake Villa. Utah Co., Utah (rainier), ami Yellowstone Park, 

 Sept. (i-12 (Scudder). These agree perfectly with eastern examples, and 

 do not have in any case all of the characters on which .McNeill sepan 

 S. color adensis, on the basis of a single female specimen from Ft. Collins, 

 Col. All the points on which lie separates this species vary to B certain 

 extent, except perhaps the length of the antenna' (in which he may have 

 been mistaken if the antenna' were curled), and I am therefore inclined 

 to think that S. coloradensis must be placed as a synonym of S. curti- 

 pennis. My Yellowstone Park specimens, all males, are of a smaller 

 size than is usual; while specimens collected by K. Thaxter in Bphagnum 

 bogs at Salmonier, Newfoundland, Aug. l-lo. are unusually green and 

 have a very peculiar aspect, hut 1 have not discovered any good specific 

 distinction from S. curtipennis. 



On the other hand, -Mr. A. P. Morse bronpht home from Oregon 

 (Corvallis, Cordley, Portland, Sept. is. Divide- Cottage Grove, Sept 12, 

 Drain, Sept. 11, Roseburg, Sept. 10, Glcndale. Sept. :». Grant's Pass, 

 Sept. 8, and Ashland, Sept. 7), and California (Gazelle, Sept. •">, Si-son, 



Aug. 29, Baden, Aug. 24, Berkeley, Aug. 21, and San Francisco, Aug. 19), 

 numerous specimens of a closely allied hut more heavily marked spei 



which seems to he distinct and may hear the name Stenobothrus oreg 

 As compared with S. curtipennis the antenna of the male are shorter 

 than, instead of as long as, the hind femora, the middle joints narrower 

 than the narrowest part of the frontal costa, instead of being at least as 

 broad as it; the fastigium of the vertex has a distinct median carina in 

 the anterior portion wanting or hardly discernible in S. curtipennis ; the 

 disk <>f the metazona is marked distinctly and generally broadly at the 

 sides with black, instead of being generally immaculate or narrowly mar-
