Orono. The colony was feeding on the stem and was accompanied by 

 ants. Alate and apterous females and nymphs were taken at this 

 time. Later, August 24, in the same locality an apterous female and 

 nymph of this aphid were found. The body of the apterous female 

 was ghstening bronze and thickly hairy. The nymph was cinnamon 

 brown. This has not been compared with actual specimens from 

 Russia, but the figures accompanying the original description seem 

 in this case adequate for determination. There is no previous record 

 of this species for America. 



EASTERN APHIDS, NEW OR LITTLE KNOWN, PART II 



By Arthur C. Bakek, Bureau of Entomology, Washington, D. C. 



Genus Myzocallls Pass 



Myzocallis punclalellus (Fitch). (1855, p. 165.) This species has 

 been placed as a synonym of caryella by Oestlund (1887, p. 45). The 

 type specimen which is in the U. S. National Museum collection 

 proves this not to be the case. The type is not in perfect condition, 

 having lost the abdomen, one antennae, the unguis of the other and both 

 hind wings. However, enough of the specimen remains to make a 

 determination positive and this remnant has been well mounted by 

 Mr. Pergande. The antenna remaining on the type measures as 

 follows: III, 0.592 mm.; IV, 0.496 mm.; V, 0.368 mm. Segment III 

 is armed with seven rather large sensoria forming a row along the 

 segment. The vertex and crown are armed with a number of tubercles 

 on which spines are mounted. The wings are without markings 

 excepting a clouding around the edge of the stigma and bands of 

 brown bordering the veins. This bordering of the veins is rather 

 faint in the type which is no doubt somewhat faded. 



Mr. Davis kindly sent me specimens of an undescribed species 

 from the MoneU collection. These specimens, No. 370 X, are un- 

 doubtedly punctatellus. The banding along the veins is more distinct 

 and the specimens are in good shape. They are alate viviparous 

 females. The following description is drawn up from the specimens. 



Alate Viviparous Female: Antennae as follows: III, 0.576 mm.; IV, 0.432 mm.; 

 V, 0.336 mm.; VI (0.144 mm. + 0.32 mm.). Segment III, with usually five large 

 circular sensoria in a row. Labium short. Abdomen with two pairs of very promi- 

 nent finger-like tubercles and with several smaller ones. Length of the larger pair 

 of these tubercles about 0.16 mm. Cornicles about 0.065 mm. Length of fore wing 

 2.56 mm. Length from vertex to tip of cauda 1.44 mm. 



General color pale yellowish. Antennal segments ringed with brown at their 

 distal extremities; tarsi, abdominal tubercles and a spot near the distal extremity 

 of the femora dark brown; wings banded with brown as previously described.
