April, 1915 Bulletin of the Brooklyn Entomological Society 37 



I have never found, however, more than two or three specimens 

 during any one season. 



Phaneus carnifex is the common species in this region but I 

 find difformis is fully as common. These vary considerably in 

 size and even the color variation in some cases is quite striking. 

 In 1886 I found my first specimen of Bradycinetus fossator in 

 Rooks County along the south fork of the Solomon River. I had 

 never seen any other specimens of this species in the state until 

 1913 when three specimens were taken on sand dunes near Medora, 

 the latter part of May, but no specimens were found last season. 

 This species is considered to be quite rare and is found in com- 

 paratively few collections in the United States. Serica curvata 

 is taken occasionally, but never in large numbers, in the sand 

 blow-out region in Reno County. They are found hidden beneath 

 the sand during the day and I have taken a very few that were 

 attracted to light in the early evening. Anomala ludoviciana 

 Schaefifer is taken but rarely in the sand hill region by sweeping 

 vegetation and is evidently a nocturnal flier. 



Cotalpa suhscrihrata Wickham is a form of the beautiful gold- 

 smith beetle and occurs over this portion of Kansas, extending 

 northward into the sand hills of western Nebraska. It appears in 

 early May and even the first specimens may be found in April. 

 They continue into June. Some years it is not found at all, and 

 other years, during a day's collecting, I have never taken more 

 than a dozen specimens. In 191 3, however, it swarmed in large 

 numbers over the sand hill region near Medora and every clump 

 of willows harbored from a half dozen to a score or more. 

 During the day they are found clinging to the willow foliage, and 

 are occasionally found on cottonwood leaves, and they may be 

 picked up from the bare sand, many of them dead but in perfect 

 condition. They fly rather lazily and noisily during the day time 

 but their full activity is evidently developed during the early part 

 of the night. They were much more numerous in 1913 than any 

 year I have observed them during my collecting in this region and 

 while they were still fairly common last season it is probable that 

 the present season will see their almost complete disappearance. 



Dascinetns trachypygiis is the common species over this region
