Zamarada delosis sp. n. 



(Text-figs 39, 40; PI. 8, figs 483, 484) 



Externally similar to small specimens of deceptrix ; in some examples the hyaline area of each 

 wing is irregularly suffused with black. 



£ genitalia (Text-figs 39, 40). Distinguished from deceptrix by the asymmetrical dorsal 

 processes of the valves ; that on the right valve is closely similar to the corresponding process in 

 deceptrix ; the process on the left valve is twice as broad in the basal half as that on the right 

 side and is then shaped as in Text-fig. 39. 



$ genitalia (PI. 8, figs 483, 484). Distinguished from those of deceptrix by the presence of an 

 acicular projection from the right-hand posterior margin of the sterigma. 



Measurements. Fore wing: 11-12 mm; $ n-o— 12-5 mm. Antennal pectinations: £ 11 x,

The PULVEROSA -Group 



Species included in the group are small, with a fore wing length of 8 '5-15-0 mm; 

 the non-hyaline terminal areas of the wings are usually greyish yellow to sepia. 

 In the male genitalia the uncus is short, with long setae dorsally at base; the ventral 

 plate of the gnathus is well developed; the valve is simple and membranous with 

 a tapered dorsal process, which is either dilate or bears a projection at one-half 

 to two-thirds; the projection may be serrate-edged and the processes are sometimes 

 asymmetrical; aedeagus usually spined or toothed at one side near apex (smooth 

 in ochrata); fulcrum well developed, except in melasma. Vesica with a short, 

 thorn-like cornutus. In the female genitalia the sterigma is well developed; the 

 corpus bursae is almost entirely membranous with a stellate signum. In the male
