Alate Vivipara. Head and thorax brownish; abdomen pale yellowish green; appendages 
pale with knees, tips of rostrum and of tibiae dark, antenna annulated. Wings hyaline, veins 
not conspicuously bordered or unusually heavy, radial sector subobsolete on proximal half. 
Body length 1.30-1.60; across eyes .39-.40; across head before eyes .27; hind tibia 1.03. 
Cornicle narrower in middle, broader at base and with pronounced flange. Cauda knobbed; 
anal plate indented. 
Apterous Summer Vivipara. Pale yellowish green; appendages pale with tarsi, tips of 
tibiae and of rostrum dark; antenna annulated. Body length 1.6-2.2; across eyes .42-.45; an- 
tenna 2.3-2.7; hind tibia 1-1.2; rostrum attaining or surpassing 2d coxa. 
Ovipara. Apterous. Same as apterous vivipara except hind tibia, proximal three-fourths 
or more of which is moderately swollen and covered with numerous small sensoria and anal 
plate which is entire. 
Male. Alate. Head and thorax brown; abdomen pale yellowish or greenish with short 
dorsal bands which are often coalesced into a black dorsal patch; appendages pale to brown- 
ish with knees, tarsi, claspers, tips of rostrum and of tibiae dark; antenna annulated; wings 
hyaline. Body length 1.6-1.7; antenna 2.5-2.7; hind tibia 1.15-1.25; rostrum attaining between 
lst and 2d coxae. ; 
Collections. On leaves of Betula sp. Colorado: Fort Collins, and Colorado 
Springs. Alate viviparae June 19, apterous viviparae June 19 and Sept. 9, sex- 
uales Sept. 9 (in Minnesota), oviparae Oct. 11 to 23; rare.

Chief Distinguishing Characters. Location of sensoria on III of aptera which 
is unusually close (.04) to base of segment, shortness of antenna (2.3-2.7) espe- 
cially IV and V (not exceeding 2.5 x base of VI), short rostral IV+V, (.09- 
.11), absence of noticeably heavy anal and cubital veins or smoky tips of veins 
of fore wing and pale body color without vittae in alate vivipara.

described state of this form and contributing specimens from Minnesota. 
~ Genus Cepegillettea Granovsky

Characters. Frontal tubercles prominent; antennal I Macrosiphumlike. Ver- 
tex and antenna with short capitate hairs; alike in alata and aptera. Antenna 
longer than body; unguis longer than base of VI; III with secondary sensoria in 
all life cycle forms; permanent sensorium at base of unguis long-oval. Cornicle 
short, truncate, imbricated. Cauda spatulate, long, with evident neck and long 
basal portion; tip Calaphislike; anal plate moderately cleft. Fore wing with 
veins heavy and somewhat bordered, at least, smoky at tip; radial sector present 
or absent. Living on leaves of trees.
