finer glandular hairs. Lateral margins of pro- and mesothorax prom~ 

 inently lobed. Lobes of mesothorax reaching second abdominal seg- 

 ment. Eyes prominent, reddish. Antennae white, slightly more than 

 one-third length of body. Rostrum white tinged with brown, reaching 

 third pair of legs. Legs white, tarsi tinged with brown. 



Fifth stage nymph. (Plate VII, fig. 7.) Length 2.2 mm. Shape 

 broadly oval. General color dark brown, almost black. Outer angles 

 of prcthoracic lobes with conspicuous light spot; median portion of 

 mesothorax light; light band extending across metathorax, first ab- 

 dominal segment and posterior portions of the mesothoracic lobes. A 

 pair of prominent tubercles on dorsal surface of head and one in mid- 

 dle of vertex, a divided tubercle on apex of hood, one on the outer 

 angle of margin of prothoracic lobe, one on either side of light spot on 

 mesothorax, one on lateral margin of mesothoracic lobe, one on lateral 

 margin of each abdominal segment beginning with the fourth, a pair 

 on the median dorsal surface of the fifth and sixth abdominal seg- 

 ments. Each tubercle bears 3 or 4 spines. There is a pair of spines 

 on median dorsal portion of second and eighth abdominal segments. 

 On the lateral margin of the prothoracic lobe there are three spines 

 anterior to the tubercle and two anterior to the tubercle on the meso- 

 thoracic lobe ; a median pair on the mesothorax posterior to the hood. 

 Eyes distinct, granular, dark brown, showing just beyond lobes of 

 prothorax. Antennae white, about one-third length of body, last two 

 segments bearing number of long fine hairs. Rostrum extending to 

 middle pair of legs. Legs white, tip of tibia and tarsus suffused with 

 light brown, each segment bearing several minute hairs. 



Adult. Corythucha spinulosa (Plate VII, fig. 8). 



Edmund H. Gibson, Trans. Amer. Ent. Soc. xliv, p. 79 (1918). 



"Hood twice as high as median carina and noticeably longer. Height 

 of hood equals about two-thirds the length of hood and not much 

 greater than length of median carina. Median carina with two rows 

 of areoles. Reticulation of hood large. Costal margins of elytra 

 nearly straight. Spines on membranous margins normally long, not 

 numerous on nervures. Size 4 mm. long, 2.5 mm. wide. 



"Hood embrowned on top. Nervures of paranota yellow, with only 

 trace of brown spots. Dark brown band across base and apex of 

 elytra. Apical band slightly less in width than one-third length of 

 elytra. Two or three large hyaline areoles in apical band and sev- 

 eral partial hyaline. . 



Differs from associate! Osb. & Dr., in having a lower hood, 

 fewer spines on nervures, two rows of areoles in median carina 

 and a narrower apical band across elytra. Distinguished from 

 cyrta Parsh., in having crest of hood more acute and angulate 

 and top from crest forward nearly straight.
