IOWA STUDIES IN NATURAL HISTORY 



2. CHAEREPHON WRIGHTI 



Copaeodes ivrighti Edw., Can. Ent. xiv, 152, 1882. 



Wrighti is probably a synonym of eunus; the original description fits 

 eunus, the type localities are in the same part of California, and we do not 

 know of two species of these general characteristics. Both of these have 

 been erroneously placed in Adopaea in the past, whereas Adopaea is close- 

 ly related to Copaeodes and eunus is not at all similar in structure.

 This is one of our rarer species. I am indebted to Mr. Leussler for a 

 specimen taken in Sioux County, Nebraska, the only one in my possession.
