SUBFAMILY APHINAE 245 
Ovipara. Apterous. Color same as in apterous summer vivipara but measurements rang- 
ing somewhat smaller and hind tibia, though hardly swollen covered for nearly entire length 
with rather large scattered sensoria. 
Male. Apterous. Head brown; abdominal segments with short dorsal dashes and laterai 
areas dark; otherwise same as apterous vivipara. Body length 1.5-2; across eyes .50; antenna 
about 4; hind tibia 2.20-2.30; cornicle .60; rostral IV+V .15-.17, attaining 3d coxa; cauda 
.15-.20 on median line, .25 entire length. 
Collections. On Rubus sp., on undersides of leaves and on tender stems. 
Colorado: Grand Mesa, Cameron Pass and Eldora. Apterous and alate summer 
viviparae June 25 to Aug. 21; rare. | 
Type. U.S.N.M. Paratypes, Hottes and Colo. Agr. Exp. Sta. Collections. 
Chief Distinguishing Characters. Slender cornicle with narrowest part 
hardly wider than base of III and widest part hardly twice narrowest part, dark 
color and absence of reticulation on cornicle, rather long rostral IV+-V (.18), 
number of hairs on cauda (4-5 lateral pairs) and presence of sensoria on III of 
apterous vivipara. 
This species differs from A. rubi in the dark cornicle and antenna, the 
longer rostral IV-+V (.18-.19 not .14-.15). This species may seem to be a syno- 
nym of A. amurensis (Mordvilko), appearing to differ only in smaller size 
(length less than 3) and the absence of swelling next to flange on the cornicle. 
However, Mordvilko in correspondence with Hottes declared tigwatensa 
“doubtless new and unlike any species on Rubus which he knew.”

Fig. 291. Amphorophora urtica 
Alate Vivipara. (Cleared and mounted on slide), body colorless with dusky lateral areas 
on all abdominal segments, inconspicuous on I and VIII and small dorsolateral spots on pos- 
terior margin of III, IV and V; head and thorax dark; entire antenna, except base of III 
lighter, cornicle, cauda, rostrum and tibiae dusky; tarsi and tips of tibiae dark. Body length 
about 3; antenna about 3.50; hind tibia 2.40-2.75; rostrum attaining 3d coxa. Hairs blunt to 
slightly capitate; on side of abdomen .02-.025 long; moderately numerous on abdomen. Cauda 
tapering, broad and blunt, bearing 4-7 hairs on each side and 2 dorsal ones. 
Collections. On grass (probably accidental)*. Utah: Lincoln. Alate vivi- 
parae June 2. 
Type and Paratypes. Essig Collection (Bartholomew Collection); type of 
alleni, Knowlton Collection. 
Chief Distinguishing Characters. Long rostral IV+V (.10), hairiness of 
rostral IV++V and of cauda, absence of reticulation on cornicle, length of corn- 
icle (about equal to IV and shorter than III) and number of sensoria on III 
(about 15-18). 
Amphorophora utahensis Knowlton and Allen 
Amphorophora utahensis Knowlton and Allen, 1945a:114. 
Alate Vivipara. ‘‘Green.’’ (Mounted on slide), pale with the following parts more or less 
dusky: Head, thorax, antenna (especially I, II and III), tarsi, -cornicle and tips of tibiae and 
of rostrum. Body length ‘1.53’’-1.80-2; across eyes .50-.55; antenna about 3; hind tibia 2-2.8; 
rostrum attaining to about abdominal III. Cauda with slight neck then nearly parallel-sided, 
bearing 3 pairs of lateral hairs and 2 dorsal ones. Cornicle moderately swollen, smooth with 
reticulations composed of closed imbrications at tip. 
*Essig described this species from numerous examples both alate and apterous vivi- 
parae taken on Urtica gracilis var. holoserica.
