Carolmaia^ n. gen. 



This genus is closely related to Cerosipha in that the alate forms have 

 six segments in the antennae, while the apterous forms have but five. 

 Antennae shorter than the body, and not placed on antennal tubercles. 

 Venation of fore wing regular, hind wings with but a single cross-vein. 

 Nectaries about one-fifth the length of the body, and swollen in the middle. 

 Cauda one-fourth the length of the nectaries and tapering. 



Carolinaia caricis^ n. sp. 

 Alate viviparous f 6771 ale. — General colour greenish-yellow, head and 

 thorax black, antennae, legs and nectaries dusky yellow. Antennas shorter 

 than the body, six-segmented and not on antennal tubercles. Sixth 

 antennal segment slightly shorter than the spur, and about half as long as 

 the third segment. Third with seven to eight round slightly raised 

 sensoria. Wings long and slender, fore wing with regular venation, hind 

 wing with but a single cross-vein. Nectaries one-fifth the length of the 

 body and swollen in the middle. Cauda very short and tapering.
