Sywpcirum nibicunduliim oMrusum (Hag.). In the open area about 

 the camp on Siskowit Bay (V, 3) this species was very abundant. Eight 

 males and eight females were collected on August 11 and 12. A male 

 was also taken near the head of Siskowit Bay (VIII, '04) on August 

 13 ; and 3 males and 1 female were taken in the sedge zone of a tamarack 

 swamp (V, 5) on August 8. The number of specimens taken is not a 

 fair index of the abundance of this species as an effort was made only 

 to secure representative forms. The open areas where the heath and 

 jnnipercladonia plant feociety were the representative types of vegeta- 

 tion, seemed to afford feeding grounds for this species and they Avere 

 very abundant in such places, It is in just such situations that the 

 small forms of insect life are most abundantly seen on the wing.
