This species is nearly allied to C. jyallidana (Zell. Isis, 1847, p. 74.2), but appears to differ

the wider dorsal patch. 
Cochylis parvimaculana. (Plate LXVII. fig. 5.) 
Head, antennae, and palpi greyish fuscous. Fore wings not three times as long as wide 
— the costa slightly arched — dull whitish, faintly mottled with pale greyish fuscous j a small 
greyish-fuscous basal patch is projected along the costa to one fourth of its length, followed by a 
greyish-fuscous spot on the middle of the costa ; the whole apical portion of the wing from the 
costa to the anal angle, as well as the cilia, irregularly streaked, mottled, and suffused with
