27. Synanthedon sanborni Hy. Edw. Dickinson Co., one, Aug- 
ust, 1915. Compared with the type by Dr. Barnes and 
said to be the same species. 
28. Melittia satyrinij ormis Hbn. Sioux City. Undoubtedly more 
generally distributed than this indicates. A number of 
other species are known to occur in the state but my 
material offers no other records.
