Apterous sexupara. — Length of body about o.6"""-. Shape 

 elongate-ovoid. Color whitish, pale yellow or greenish-yellow, 

 with the members and warts dusky. ' Eyes dark purplish-red. 

 Surface of body densely covered with minute points. The dorsal 

 warts are normally placed, though faint, those on the thorax 

 round, with the intermediate one each side on pro- and meso- 

 thorax obsolete, leaving on each of these joints but two trans- 

 verse rows of four each, while the single row on metathorax has 

 six. On the abdomen the two medial rows are transversely 

 elongate. In some specimens these warts are very distinct and 

 readily observed, while in others they become more or less obso- 

 lete, and on the abdomen they are more or less confluent towards 

 tip. Antennae short and very similar to those of the stem- 

 mother; the third joint scarcely longer than the two basal joints 

 combined, somewhat curved, thinnest at base, with but few and 

 indistinct annulations ; the thumb rather stout and close to the 

 tip of the joint. When young the rostrum projects beyond the 

 end of body. 



Sexual female: — Length of body slightly less than 0.2"'"''. 

 Shape broadly ovoid, with the last two segments much narrower 

 than the test of the body. Mouth rudimentary, broad and 

 rounded at tip. Color yellow ; eyes purple ; antennae and legs 

 faintly dusky. The antennae are extremely short, the third joint 

 but slightly the longest, and the second slightly shorter than the 

 first. Joint i stoutest, of uniform diameter, truncate anteriorly ; 

 joint 2 but slightly narrowing at base; joint 3 also narrowest at 

 base, bluntly rounded at tip and provided with a slender hair, its 

 surface faintly annulate ; the thumb minute, though distinct and 

 placed close to the apex. 



Male. — The male is about one-fourth smaller, and narrower 

 than the female. Antennae, legs and genital armature rather 

 stout. Color pale yellow ; eyes brown. 



Winter-egg.— Length slightly less than 0.2""-. Shape ovoid, 

 sometimes faintly curved, somewhat flattened, dark, dull, grayish- 

 yellow or green, ornamented with rather coarse and deep, more 

 or less irregular, transversely oval pits. 



During the summer of 1902 another effort was made by me to 

 discover, if possible, the winged migrant of this species, though
