Alate viviparous female : General color in balsam deep brown. 

 Antennae and legs dark brown, with the tarsi tips of the tibiae and 

 distal three-fourths of hind tibiae deep dusky brown. Antennae 

 long and slender ; the third segment has ten to twelve round sen- 

 soria which vary more or less in size. The fourth segment has 

 two or three sensoria and the fifth one small and one large one 

 near the distal end. Rostrum long and slender reaching nearly to 

 the tip of the abdomen. Wings long and broad with the angle 

 formed by m^m^ extending well beyond the base of the radial 

 sector. Hind tibiae long and slender and slightly curved but not 

 so much so as in the apterous forms. Cauda bluntly angular. 

 Antennae, body and legs with short stout spines.

Alate viviparous female : Specimens in balsam show no distinct 

 coloration of antennae and legs, these parts appearing to be light 

 dusky throughout. Third antennal segment approximately equal 

 in length to the fourth and fifth segments, fourth segment shorter 

 than the fifth, fifth and sixth about equal. Third segment with 

 about six round sensoria of irregular size and not in alignment; 

 fourth segment with two and fifth with two. Beak extending to 

 the tip of the abdomen. The antennae are quite distinct from 

 those of the other species in this genus and the cornicles are much 

 broader at the base than those of Schizolachmis tomentosus. 

 Cornicles with a wide sloping base. Cauda rounded, anal plate 

 angular. Antennae, legs and body with a moderate number of 

 medium hairs. 



Measurements: Length of body, 1.8 mm. Length of antennal 

 segments, iii, 0.37 mm. ; iv, 0.166 mm. ; v, 0.187 mm. ; vi, 0.187 mm. 

 Total length, 1.02mm. Rostrum, iii, 0.21 mm.; iv, 0.21 mm.; v, 

 0.07 mm. Total length, 1.82 mm. Length of hind tibia, 

 1.36 mm. ; hind tarsus, 0.083 mm. and 0.21 mm. 



Food plant : Juniperinus virginiana.
