is dusky-black excepting the base which is olive-green; only slightly 

 narrower than the prothorax. The eyes are dark red or brown with 

 well developed lateral tubercles. The antennae are dusky brown 

 or nearly black with numerous concentric rows of short dark spines 

 as in the stem mother and all other forms of this species; 6-articled; 

 few normally long spines. The lengths of the articles are as fol- 

 lows: I, 0.055 mm.; II, 0.05 mm.; Ill, 0.23 mm.; IV, 0.13 mm.; 

 V, 0.12 mm.; VI, 0.14 mm.; total, 0.725 mm. The length varies 

 with the size of the adult and the measurements may differ consider- 

 ably from those given above. The sensoria are large, transverse 

 and vary somewhat In number and location. Of a large number 

 of specimens examined the following tabulations are normal: III, 

 from 8 to 15; IV, from 1 to 5 ; V, 1 ; VI, 2. The thorax is dark 

 olive-green with the muscle lobes black. The abdomen is dark 

 olive-green with irregular dark-brown or nearly black markings as 

 shown in Fig. 6. In the living forms a white cottony wax is secreted 

 from the sides near the cornicles and partially hides the body. The 

 cornicles are very short, wider than long, hairy and black. The 

 wings are hyaline with dusky-amber veins. The primary wings are 

 2 mm. long and 0.7 mm. wide. The venation is shown in Fig. 6. 

 The secondary wings are narrow, 1.2 mm. long and 0.3 mm. wide. 

 The legs are rather small, dusky-brown with few hairs. The cauda 

 is broadly rounded with long spine-like hairs. 



Winged Viviparous Female 

 The size, color, shape and general appearance are much the same 

 as the winged oviparous female just previously described. The 

 white waxy secretions of the abdomen, howev^er, are wanting and 

 the dark markings on the dorsum of the abdomen are often very 

 indistinct. In some specimens the tips of the middle and hind tibiae 

 are noticeably enlarged. 



Immature Forms 

 The immature forms are almost transparent and colorless when 

 first born, but gradually assume a yellowish-green and finally an 

 amber or dark olive-green color with the markings of the adult 

 forms.
