236 APHIDS OF THE ROCKY MOUNTAIN REGION 
Type. U.S.N.M., No. 41922. Paratypes, Colo. Agr. Exp. Sta. Collection. 
Chief Distinguishing Characters. Comparative lengths of III and IV (about 
coequal), number of sensoria (14-26) on III of alate vivipara, smooth, unreticu- 
lated, slightly swollen slender cornicle (hardly wider than hind tibia), hairy, long 
(.25) rostral IV+V, rather bushy cauda (6-7 hairs on a side) and length of 
cornicle (about the same as III). 
Amphorophora goldamaryae Knowlton 
Amphorophora goldamaryae Knowlton, 1938a:13. 
Apterous Summer Vivipara. (Mounted on slide), pale on entire body; cornicle, cauda 
and legs pale except tips of tibiae and tarsi which together with antenna beyond proximal 
two-thirds are more or less dusky. Body length ‘‘2-2.5’’; across eyes .48; antenna about 3; 
hind tibia 1.80-‘‘2.10’; rostrum attaining between 2d and 3d coxae. Cornicle slightly swollen, 
imbricated with imbrications closed just before tip. Cauda slender, tapering, bearing about 
3 pairs of lateral hairs and one preapical one.

Fig. 277. Amphorophora goldamaryae 
Alate Vivipara. Same as aptera except antenna, especially beyond proximal tenth of III, 
and tips of cornicle and tibiae dark to black. Body length 2.50; across eyes .50; antenna 
about 4; hind tibia 2.3-‘'2.5” ; rostrum hardly attaining 2d coxa.

Cotypes. U.S.N.M. and Knowlton Collection. 
Chief Distinguishing Characters. Moderately swollen cornicle (at widest 
portion less than twice diameter of narrowest part), length of cornicle (about 
.75 long, shorter than to equal to III), length of reticulated area on cornicle 
(.03-.05), length of rostral IV+V (.13), number of sensoria on III (not more 
than 20 in alate vivipara, 3-4 in aptera) and their absence on IV, length of III 
(.75-.95) and length of IV (.50-.75, not longer than seven-tenths of III). 
From A. brevitarsis this species differs only in the shorter cornicle (shorter 
than III, not .80-1.10 in aptera and not 1-1.05 in alate vivipara) and the shorter 
area of reticulation (not .06-.08). The two species are doubtfully distinct but, 
since the host plants differ radically, the two forms must be considered distinct 
awaiting transfer tests and migration observations.
