little more than half the length of the honej-tubes. Total 

 length of the body, 1.99 mm. 



This form was taken July 12, on the dorsal side of the tender- 

 est leaves of burdock (Arctium lappa) . It is gregarious in 

 habit, but not very numerous. Its colonization of the burdock 

 lasted only a short time this last summer.

Head black. Antennir dark, imbricated, and bare ; length of 

 segments: 1,0.03 mm.; II, 0.05 mm.; Ill, 0.25 mm.; IV,

 tal length, 1.25 mm., or about the length of the seventh joint 

 shorter than the body. Sensoria circular, giving the antennae

 ones. Eyes black, with a purple tinge ; ocular tubercles promi- 

 nent ; ocelli prominent. Beak dark, 0.36 mm. long, extending

Prothorax short and dark. Thorax black and well developed. 

 Wings subhyaline, venation dark, discoidals quite straight. 

 Stigma not as dark as the veins, 0.54 mm. long and 0.12 mm. 

 broad. Total wing expansion, 5.12 mm. Legs slightly hirsute ; 

 tarsi, distal part of the tibia, and all but the proximal part of 

 the femora black. 



Abdomen dark green. Honey-tubes black, incrassate, ex-

 Total length of the body, 1.63 rara. 



This form was taken June 6, on the honeysuckle (Lonicera 

 sempervirens ( ?) ) . It is gregarious in habit and colonizes the 

 ventral side of the leaves. The colonies have not been very 

 prosperous here while this collecting has been done.
