a few more, one July day, near the upper end of a deep gully, washed 

 in clay soil by the rains a mile west of town. The time was about 

 four o'clock p. M , and the little fellows were apparently at rest in the 

 shade of the high bank, one pair in copula At Council Bluffs, on 

 the Missouri River, I had a few hours to spare between trains while 

 on my way to Denver in June, 1897, and went up the high clay hills 

 just back of the town, following one of the numerous paths Near 

 the top of one of these bluffs I noticed a C. celeripcs run across the 

 path, and careful work in the way of frightening them out by disturb- 

 ing the scattered grass-clumps (under which they seem to lie) was 

 rewarded by the capture of six or eight examjjles They seemed to 

 make instinctively for cover and at this time of day — it was just after 

 noon and very sunny — were so wonderfully agile that in spite of 

 inability to fly the chances of escape were many. On my return 

 about a month later I spent a short time, near the end of the after- 

 noon, at the same spot and found a few more. It is evident that the 

 insect is not entirely crepuscular in habit, though I had thought it 

 might be partially so. 



The variety ciirsifans Lee, has been taken by Mr. Hugo Soltau at 

 Covington, Louisiana. He found it in abundance on yellow sand in 

 open timber a little way from the banks of a small stream. I have 

 one specimen which was taken by my brother, climbing a stee]) bank 

 along the Iowa River near Iowa City. 



C. obsoleta Say. Has been taken, with its varieties, by Prof. E. A. 

 Popenoe in Meade County, Kansas, on roads or prairies of loamy or 

 clayey soil. It occurs in a straggling manner, not in companies, and 

 is shy. Short growth of vegetation docs not repel it, but it prefers 

 bare ground. Mr. Roland Hay ward took the variety viilturina Lee, 

 at Durango, Colorado, between July 25 and August 8, and in the San 

 Juan Valley, Taos County, New Mexico (4500 teet), between August 

 I and 4. It occurred on adobe soil on the plains, among the sage- 

 brush and greasewood, scattered or singly. 1 found an example 

 of the \2iX\eiy prasina Lee, at Seligman, Arizona, in July. It was 

 out on the dry open prairie in the brush. Mr. Knaus has it from 

 dried-up beds of lakes and pools near Coolidge, Kansas, August 12. 



C. unipunctata Fabr. This rather rare species I have met with only 

 once — on a dark rainy day at the end of May, in Cedar County, 

 Iowa. I had been collecting along the river bottom and saw this
