long. 



Length of body, 2.10 mm.; antenna, 2.90 mm. Joints of antenna 

 about as follows : III .60, IV .43, V .40^ VI .15, VII .90 mm. Cornicles, 

 .66 mm., and distinctly but not strongly clavate. Wing, 3 mm. long, ven- 

 ation normal, each nervure terminating in a small dusky spot on wing 

 margin. Stigma long and narrow, stigmatic vein very convex. 



A very abundant species on tender terminal twigs of wild and culti- 

 vated roses about Fort Collins now. Many viviparous females getting 



wings. 



Apterous Viviparous Female. — Differs from preceding by having the 

 body light green throughout, antenna with 7th joint black, and the others 

 light green annulated with black at joints and no sensoria on 3rd joint; 

 distal portion of tibii^e, femora and cornicles hardly dusky, if at all. Taken 

 along with the alate form above. 



Apterous Oviparous Female. — (Plate 3, figs. 4 and 5). On rose bushes, 

 Fort Collins, Oct. 17, 1907. 



Adult oviparous females are light orange-red in colour upon head, 

 anterior portion of thorax and terminal portion of the abdomen, including 

 the Cauda. The eyes are very dark red. The metathorax and all the 

 abdomen to the region of the cornicles is light to very dark dusky green. 

 Usually a broad pale yellow or yellowish-green area crosses the abdomen 

 in the region of the cornicles, this light colour sometimes extending to the 

 tip of the abdomen. In some specimens the entire body is pink in colour, 

 the dark markings being fairly uniform. The antenna is pale in proximal 

 half with distal ends of joints 3, 4 and 5, and all of joints 6 and 7 black ; 

 legs dusky yellow with tarsi and distal ends of tibiae black or blackish ; 

 cornicles also dusky yellow with extreme tips black, gently curved and 

 moderately clavate. 



Length of body, 2 mm.; antenna, 2.5 mm. Joints : III .60, IV .40, 

 V .43, VI .15, VII .80 mm. Cornicles, .68 mm.; cauda, .25 mm.; 

 antennae upon strong tubercles, prothoracic tubercles wanting, 2nd joint of 

 antenna gibbous upon inner side. 



A few light yellow viviparous females still on the leaves, but most of 

 the lice are oviparous females and winged males now. A few eggs,
