comparison of the numbers of each species taken during the summer 

 months turns out the following : June, 3 cuprascens and 21 macra ; 

 July, 202 cuprascens and 122 macra; August, 26 cuprascens and 10 

 macra. Many of these were taken at the electric lights. 



In the fall of 1902 I had the privilege of taking a trip into western 

 Kansas with my father. We found cuprascens, punctulata and mi- 

 cans at the lights at Dodge City, August 31. The next day, Septem- 

 ber 1, we found the type formosa in abundance in the sand-hills across 

 the river south of town, and the closely-related venusta in much less 

 numbers. One or two scutellaris were also taken. In an alkali ditch 

 near the river three examples of fulgida were found, in company with 

 vulgaris. A few cuprascens were taken on the sand-bars, and a fine 

 specimen of micans was found on a dry road across the prairie on the 

 hills north of town. 



At Coolidge, September 2, over forty specimens of pulchra were 

 taken on bare clay flats on the high prairie. Near the river two speci- 

 mens of nigrocperulea, the first taken in the state, were found amongst 

 the salt-grass by irrigating ditches. On September 3 a number of 

 fulgida were taken on saline spots near a slough in the low prairie ; 

 on sand-bars in the Arkansas were taken a pulchra, a few vulgaris, 

 some very close to obliquata, and several each of venusta, ponderosa, 

 micans, and cuprascens. The venusta chose the fine drifting sand in 

 the hot shelter of the bank, the vulgaris and ponderosa the flat open 

 sand-bar, and the micans and cuprascens the wet sand next the water. 



On September 4, at Coolidge a single prasina was taken in the 

 dried bed of a rain pool, several micans at the edge of fresh rain 

 pools, and a number more of pulchra on the bare ground near the 

 pools, on the high prairie north of town. At Ness City, September 5, 

 was taken a single formosa with markings similar to the variety 

 manitoba. 



A second trip to western Kansas, toward the last of September, gave 

 the following results : 



At Oakley, September 24, graminea and audubonii were found in 

 plenty along unused roads across the prairie, averaging about three of 

 the former to one of the latter. When frightened they would often 

 rise to a great height, and fly far off with the wind. It was noticed 

 that audubonii generally chose depressions in the prairie, where the 

 road was damp and the ground dark. A single specimen each of 

 pulchra, scutellaris, and formosa, and several micans and vulgaris were 

 also taken. The next day, at Salina, September 25, we found a few 

 purpurea, graminea, splendida, and amoena, along an earth-ballasted 

 railroad- track, on the path between the rails. 



In an hour's collecting, September 27, at Clearwater, south of 

 Wichita, over sixty specimens of scutellaris, all immaculate, were col-
