RILEY REMARKS ON CANKER-WORMS, ETC. 



277 



VERNATA. 



No white band, and rarely any 

 marginal dots. 



Under surface with a more or less 

 distinct dusky spot on each wing, 

 the front wing having in addition a 

 dusky line along median vein and 

 spot on costa toward apex. No pale 

 bands. 



Female — AntenncE generally with 

 but few inore than 30 joints, the 

 longest about thrice as longaswide, 

 faintly constricted in middle, and 

 pubescent. (Fig. 16, c.) 



Body and legs pubescent, clothed 

 with whitish and brown, or black, 

 dentate scales or hairs ; general co- 

 loration not uniform. Crest of pro- 

 thorax and mesothorax black. A 

 black stripe along the middle of the 

 back of the abdomen, often inter- 

 rupted on the second to seventh 

 joints, with a whitish patch each 

 side of its front end. (Fig. 16, i.) 



Abdomen tapering rather acutely 

 behind, and with an exsertile, two- 

 jointed, conspicuous ovipositor. — 

 (Fig. 16, e.3 



Two rows of spines on back of the 

 first seven joints more prominent 

 than in the male, and often giving 

 the dorsum a reddish aspect. (Fig. 

 16, ^.) 



Of a rather smaller size than 

 pometart'a, the wings of the male 

 expanding from 0.86-1.30 inches, 

 and the female measuring 0.20-0.35 

 inch in length. 



POMETARIA. 



In most specimens a curved white 

 band runs across the wing, and the 

 veins inside this band and on hind 

 border are generally dotted. 



Uftder surface with a dusky dis- 

 cal spot on each wing, and with 

 the outer pale band on upper sur- 

 face of frQnt-wings as well as that 

 of the hind-wings showing distinct- 

 ly, the former relieved by a dusky 

 spot inside at costa. 



Female — AntenncB with over 50 

 joints, the longest hardly longer 

 than broad ; uniform in diameter; 

 without pubescence. (Fig. 20, c.) 



Body and legs smooth, clothed 

 with glistening brown and white 

 truncate scales intermixed, giving 

 it an appearance of uniform shiny 

 dark ash-gray : somewhat paler 

 beneath. (Fig. 20, b, d.) 



Abdomen tapering rather bluntly 

 behind, without exsertile oviposi- 

 tor. 



No spines on abdomen. 



The wings of the male expand 

 from 1.05-1.35 inches ; and the fe- 

 male measures 0.25-0.40 inch. 



From the above detailed descriptions of the two species it is 

 evident that, as alread}' remarked, pometaria alone can be refer- 

 red to the genus Anisopteryx., and this doubtfully. It agrees with
