Female. — Differs from the female of variety angustior in 
the following characters; Parapsidal grooves more gradually 
convergent toward and more separated at the scutellum; med an 
groove distinctly but discontinuously indicated for one half the 
mesonotal length; anterior parallel lines not as distinct toward 
the pronotum; the smooth area on the scutellum is larger, more 
rugose, and connected to the mesonotum by a much wider 
isthmus; the transverse, rugose band across the mesopleura is 
considerably wider and less distinct in outline; the rufous area 
on the abdomen, dorso-basally, is larger and lighter; the areolet 
is a little smaller. 
Male. — Differs from the male of variety angustior only in 
varietal characters as described for the female. 
Gall. — Practically the same as the gall of angustior. 
Range. — Utah: Thistle (Weld), Price (Kinsey). Probably 
occurs throughout the Colorado Plateau country of parts of 
Utah, Colorado, New Mexico, and Arizona.

Female. — Differs from utahensis in the following characters: 
Parapsidal grooves make an abrupt curve in, and converge more 
closely at the scutellum; median groove is variable, from a 
mere indication at the scutellum to discontinuous indications 
for one-third of the mesonotal length, and is less distinct; an-
