My next stop was at Medicine Bow, fifty miles northwest of 

 Ivaramie. This station was my closest railway point to the old 

 station of Aurora, on the edge of Lake Conio, where I wished 

 to look for Cicindela tvillistoni Lee. From Lookout to Medicine 

 Bow the old railway line was abandoned and taken up, and one 

 must walk back east eight miles from Medicine Bow to reach 

 Lake Como, situated in a small mountain basin. In the eight 

 miles walk you do not .see a single habited house, but at Lake 

 Como is the Berry ranch, near the abandoned station site. A 

 brisk walk from Medicine Bow, Sunday morning, June 23rd, 

 with a few stops to look for insects under the old ties along 

 the dismantled road-bed, brought me about eleven o'clock to 

 the southwest point of the mountain lake, covering something 

 near one hundred and sixty acres. On the maps the lake is 

 nameless, but is known locally as Lake Como. The water is 

 charged with alkali and has a soapy appearance. From the 

 old road-bed a small rivulet leads into the lake some seventy- 

 five yards away, and the alkali wash towards the lake is either 

 bare of vegetation or scantily covered. On this alkali soil near 

 the edge of the lake, S. W. Williston, the latter part of June, 1 877, 

 while hunting fossils in the adjacent mountains for Yale Col- 

 lege, accidentally found a species of Cicindelidae that was unde- 

 .scribed. Dr. Leconte described the species as zvillistoni, naming 

 it for the discoverer. Some fifty or sixty specimens were taken 

 by Prof. Williston, and up to this year, with the possible excep- 

 tion of a dozen specimens, this has remained a record of the 

 catch of this species. 



On my arrival at the lake I was not long in locating its haunts, 

 and soon had my first specimen in the cyanide bottle. Collect- 

 ing was good until 3.30 p.m. . when the lateness of the hour and 

 the continued use of my net had reduced the numbers visible to 

 an occa.sional specimen, I found they occurred only over a 

 small area of bare pr scantily reed-covered white alkali soil,
