Apterous Oviparous Female. — Prevailing color cinnamon brown to 

 brownish black, shining, with head and pro- and meso-thorax a sordid 

 pale yellowish green to light brown; beneath, pale greenish yellow, 

 darker posteriorly and at lateral margins of abdomen; a heavy covering 

 of white secretion upon the tergum and pleuras of the abdomen back of 

 the cornicles to the tenninal scginent, which is exposed; cornicles black, 

 moderate in size of basal enlargement; antenna? with tips of joints 3, 4 

 and 5 and all of G black; beak nearly attaining the tip of the abdomen; 

 forni rather elongate; legs colored as in apterous viviparous female; 

 hind tibise, with many small sensoria; hind legs very short; tibias but 

 little swollen; length of bodv 3; antenna, 1.50; joints: III, .51; IV, .28; 

 V, .29; VI, .20; hind tibiae, 2.50. See figures 11-13. 



Eggs. — They are deposited in single rows on the upper surface of 

 the needles and are covered \\ath a rather coarse, waxy material from 

 the abdomen of the oviparous female. As soon as an egg is deposited, 

 the female rubs her hind tarsi in the waxy secretion on her abdomen and 

 then rubs them over the egg and continues this ])rocess till the latter is 

 well covered with the short, broken bits of wax as shown in figure 14. 



Alate Male. — Described from alcoholic material taken by Mr. 

 L. C. Bragg from Engelmann spruce at Fort Collins, Colorado, Novem- 

 ber 9, 1900, along with the oviparous 9 9 • 



Black parts, proportions of antennal segments, and cornicles as in 

 alate viviparous 9 ; length of body about 2.70; wing, 3.90; antenna, 

 1.45; hind tibia, 2.12; sensoria of antennas numerous on joints 3 to 6, 

 circular in form and varying much in size. The numbers upon the 

 segments run about as follows: III, IS; IV, 14; V, IS; VI, aside from 

 the rather scattered cluster of small sensoria about the permanent one, 

 there is 1 or 2 on the basal half. See figure 15. 



This is a common species upon Engelmann and blue spruces 

 in Northern Colorado, which we have been taking for the past 

 eight years. It is a bark feeder and has always been found by 

 us attacking small limbs where the lice insert their beaks in the 

 crevices of the bark. As in other species treated in this paper, 

 the color markings of the young lice are very distinctive.
