This species is common in the same situations as the last; 

 it is apparently more numerous in the eastern portion of the 

 state than in the west. The series exhibits considerable varia- 

 tion, but the majority of the specimens are of the liictuosus 

 type. 



Oecanthinae 



Occanthus qnadnpunctatus Beutenmuller. — Devils Lake, 

 July 20-Aug. 14. 1920, 48 males, 35 females, 10 juveniles; 

 Sheyenne River, Eddy Co., Aug. 8. 1920, i male, 4 females; 

 Fargo, Aug. 31, 1920. 3 males, 7 females; Buford, July 23, 

 1920, I juvenile; Amidon, Aug. 21-27, 1920, 26 males, 17 

 females. 



This species was common throughout the state in grassy

 brushy margins of woods in the eastern part of the state. 

 Although nymphs were very abundant during the earlier part 

 of July, the first adult was not taken until the 28th of that

 August. This species was common on the upper flats around 

 Devils Lake, among the tall herbaceous growth and low 

 bushes; it seemed to be especially fond of the sticky flowers 

 of Grindelia squarrosa, and in a patch of these plants almost 

 every other blossom would have an Oecanthus stretched out 

 across its disc. Nymphs were seen at Bottineau, but no adults 

 were taken there. 



All of the specimens in this large series (78 males, 63 

 females, 11 juveniles) are very light in coloration, without 

 or with only the faintest traces of the fuscous markings char- 

 acteristic of Oecanthus nigricomis. They tuidoubtedly all 

 belong to the same species. Nevertheless, the antennal mark-
