SUBFAMILY APHINAE 43 
Cinara idahoensis Knowlton 
Cinara tdahoensis Knowlton, 1935b:283. 
Alate Vivipara. Body length about 2; across eyes .50; antenna -80, III .24, without sen- 
soria, IV .10, with one secondary sensorium, V .14, VI ‘.13-+.02”; cornicle .17 in diameter at 
base; rostral IV .15, V .07, attaining nearly to tip of abdomen; hind tibia 1,253) hind tarsal 
II .23. Hairs on hind tibia at angle of over 45 degrees, .14-.18 long, about twice as long as 
diameter of tibia; on antenna short, sparse and inconspicuous. 
Apterous Summer Vivipara.* Indistinguishable from C. winonkae. 
Collections. On Thuja sp. Idaho: Twin Falls. Alate vivipara (a single 
specimen) and apterous viviparae April 12. 
Type. Knowlton Collection. 
This species is distinguished from C. winonkae only by inconspicuous hair 
on the antenna of the alate form and that only a single specimen. Study of a 
larger number of alatae may settle the status of this form.

Cinara juniperensis, Gillette and Palmer, 1931:858. 
Alate Vivipara. Head and thorax blackish, abdomen light greenish brown; slight pul- 
verulence on thorax and on abdomen on intersegmental lines and lateral areas anterior and 
posterior to cornicles; appendages yellowish with dusky tips on segments, hind tibia dusky on 
distal third to half. Fore wing with radial sector and Ist anal vein ending in smoky brown 
area. Body length 4; hind tibia 3.2; antenna 1.75; cornicle about .40 in diameter at base. 
Hairs on hind tibia 1.5 times as long as the diameter of tibia; on antenna and body .12. 
Rostrum attaining about middle of abdomen. Fore wing with media only once-branched. 
Ovipara. Apterous. Yellowish to dark brown throughout with abdominal VII and VIII 
pulverulent; appendages dusky except proximal half of III; cornicle black. Body 3.5 by 2; 
hind tibia 1.6-2; antenna 1.3; cornicle .25-.40 in diameter at base of cone. Hairs as in alata. 
Hind tibia hardly swollen but bearing scattered sensoria along almost entire length. 
Egg. Black; naked. Size 1.4 by .6. 
Collections. On Juniperus sibirica, on bark of twigs. Colorado: Rocky 
Mountain National Park and Pingree Park. Alate viviparae Aug. 20, oviparae 
Aug. 24; rare. 
Type. U.S.N.M., No. 41944. Paratypes, Colo. Agr. Exp. Sta. Collection. 
Chief Distinguishing Characters. Pulverulence generally slight but heavy 
on tip of abdomen of ovipara, moderately long tibial hairs (.13) and long hind 
tarsal II (in alata .44 about twice as long as rostral IV). 
This species needs further investigation, as very few specimens have been 
taken. The difference in length of hind tarsus in the two forms studied seems 
strange. No life cycle observations have been made.
