style of the winged viviparous female and antenna of the wing- 

 less female are given on Plate III, figs. 46 to 50. As indicated 

 above this species appears to be a synonym of A. gossypii Glover. 



54. A. lonicerae Monell. 



55. A. lonicericola Williams. 



" Aphis lonicericola n. sp. No. 70. On Lonicera parviflora, 

 Ashland, May 14, 1890." 



Several wingless adults and immature on the slide, all in rather 

 poor condition. Antennal measurements of five antennae as 

 follows : 



Cornicles measure 0.204 ™^ ^^ length. Style short and tri- 

 angular, being not unlike that of A. lonicerae Monell. Camera 

 lucida drawings of the antenna, cornicle and style of wingless 

 viviparous female are shown on Plate III, figs. 51 to 53. 



56. A. lugentis Williams. 



" Aphis lugentis n. sp. Type No. 71. On Senecio lugens, War 

 Bonnet Cr., 6/23, '90." 



On this slide is one winged female, two wingless adults, and 

 several immature. 



Winged viviparous female: This species is remarkable in that the basal 

 one fourth of the hind tibia is swollen and bears 15 to 17 more or less 

 circular sensoria. Antennae on moderate frontal tubercles, and reaching 

 to about the base of the cornicles. Sensoria on antennal segments as fol- 

 lows, 28 irregularly placed on III, 11 to 15 more or less in a row on IV, 

 and 3 to 4, not including the usual distal one, on V. Antennal measure- 

 ments follow : 



It might be noted here that in his original description Williams says, " III 

 longer than VII, but shorter than VI and VII together," which is not true
