One apterous viviparous female was also taken at Orono on Alnus 

 incana on June 26, 1909 (Maine No. 45-09), and one in 1904 (Maine 

 No. 48-04 Sub. A).

This is the type species of the genus. The type slide (bearing 

 tliree apterous viviparous females) exists in the British Museum. 

 Frederick Laing writes that segment III of these specimens have 

 from 30-34 sensoria, reaching nearly the length of the segment. 

 Drawings kindly loaned by him show the hairs of III to be less than 

 half the width of the segment and capitate. The cornicle is shown 

 to be about three-fifths as long as III, moderately slender, conspic- 

 uously swollen, and with no reticulations or imbrications. 



As explained on page 3, this species is known only from the type 

 slide. 



AMPHOROPHORA AMURENSIS Mordviiko 



Acyrthosiphon (AmpJwrophora) rubi amurense Mordvilko, Fauna de la 

 Russie, vol. 1, liv. 2, 1919, p. 267. 



Mordvilko described this form as a subspecies of ruhi Kalten- 

 I)ach. I have not seen it, but judging from his description it is a 

 good species. It may be separated from its near relatives by the 

 characters given in the key on page 54. I quote herewith a trans- 

 lation of Mordvilko by A. J. Bruman. 



Apterous viviparous female. — Body spindle shaped. Depth of frontal fur- 

 row is two-sevenths to one-third the distance between the bases of the antennae. 

 Antennal tubercles quite convex. The projection of the vertex is distinct. 

 Antennae only slightly longer than the bodj' (one and one-twenty-fifth to one 

 and one-fourteenth times). The third segment is one and one-fourth to one 

 and one-third times longer than the fourth, and the fourth nearly that many 

 times longer than the fifth. The base of the sixth segment is one-sixth to 

 two-thirteenths the length of the third, and the tip of the sixth is only very 

 slightly less than the length of the third segment (for instance eleventh-twelfths 

 of that length). The capitate hairs on the third segment reach four-fifths to 

 three-fifths the diameter of the proximal part of the segment. Near the base 

 this segment has 6-12 secondary sensoria. The cornicles reach two-ninths to 

 one-fourth the length of the body. At a distance of one-third from the end they 

 are swollen. From here toward the base they first become narrow and then 

 at the very base they widen considerably. In front of the flange there is another 

 slight (hardly noticeable) swelling. No sculpture is seen on the walls of the 

 cornicles. The cauda is two to two and one-half times shorter than the cor-
