Corizus viridicatus Uhler, Fifth Aun. Eep. U. S. Geol. Surv. for 1871, 1872, p. 404. 



This species is very widely distributed in Eastern Colorado : at least 

 that is the case with the variety which I described under the name of 

 viridicatus. It lodges in the flowers of various weeds and flowers, and 

 seems to be common upon the plains, foot-hills, and parks in the mount- 

 ains. It was less abundant in Clear Creek Canon, but was found every- 

 where west of Denver, around Colorado Springs, and near Manitou. It 

 lived singly in the crowns of small flowers in Manitou Park, and was com- 

 mon upon weeds in the Arkansas Valley and near the mouth of the canon 

 of the Arkansas from August 4 to 19, I failed to find it on the plains 

 near Bijou, Dr, Packard found it at Golden July 3, and ou Arapahoe 

 Peak, 11,000 to 12,000 feet above sea-level, on July 1.
