 and part of luidtarsus. Cell of forewing either entirely scaled, or the vitreous

 hindwing scaled beyond end of cell. 



S. Tenth tergite truncate, tip of each jirocess sinuate, essentially as in 

 fucijormii \ sternite (PL XLIII. f. 25) asymmetrical as in gracilis, the vestige of 

 the right lobe {>■) rather more obvious than iti other species. Left clasper 

 (PI. LL f. 17, I) very slender, somewhat spatulate, rounded dilated ventrally near 

 base, process of harpe (//) represented by a short jirojection accompanied by a 

 broader and lower hump which bears some bristles ; right clasper (/■) also slender, 

 shallowly emarginate ventrally beyond middle, harpe ending in a club-shaped 

 process which bears long spines on the upperside at apex. Penis-funnel (I'-f) 

 smooth, not granulosa ; penis-sheath (p) ending in a long, but not sharply pointed, 

 process. 



Larva green, with a rather sharply defined reddisli ventral band, which is often 

 restricted to the last segments, dorsal mesial line accompanied at each side by a 

 white line ; a yellowish dorso-lateral line ending at horn. — Food-jilants : Vihiirintm-. 

 Symjjhoricarpus ; Primus ; Crataegus ; etc. 



A variable sjiecies. We distinguish three principal forms, which ai'c connected
