a course midway in the space between the second obhque and stigraatic 

 veins, and forks about half-way to the tip of tlie wing. Tlie stigmatic cell 

 is long and slender. The wliole wing is very narrow, but its exact pro- 

 portions are uncertain ; probably it is more than three times as long as 

 broad.

Anconatua Buckt., Monogr. Brit. Aphides, IV, 177 (1883). 



Head rather small, subquadrate, broader than long, the front entire 

 and straight. No frontal tubercles. Antennas apparently much shorter than 

 the body, very slender, separated by twice the width of the basal joint, the 

 first and second joints quadrate and successively smaller, the third half the 

 width of the first. Wings narrow, the stigmatic vein arising at about the 

 middle of a pretty large and long stigma, so that the stigmatic cell is 

 generally about a third the length of the wing. Cubital vein very feeble, 

 once forked before, generally considerably before, the stigmatic vein and 

 at a moderate distance from its own origin, wliich is in the second fourth of 

 the space between the first oblique and stigmatic veins. Second oblique 

 vein arising about twice as near the first oblique as the cubital vein, diverg- 

 ing considerably from the first oblique vein which is unusually transverse, 

 but the first discoidal cell is only three or four times as broad on the hind 

 margin as at the base. Legs moderately stout but long, the middle femora 

 being nearly as long as the width of the body, the hind femora as the length 

 of the abdomen. Abdomen stout ovate, considerably broader than the 

 thorax, broadest behind the middle, somewhat pointed apically, with no 

 Cauda, and only short cornicles.

Cubital vein forkiug a long way before the stigmatic vein, and arising only a little before the middle 

 of the space between the first obliqne and stigmatic veins 1. A. dorsuoam. 



Cubital vein forkiug only a little before the stigmatic vein aiul very far from its origin, which is at 

 p,bout the middle of the proximal half of the space between the first obliq[uo and stigmatic veins.
