Paedisca agricolana. (Plate LXIX. fig. 8.) 



Head, palpi, and thorax milk-white ; the head tufted above ; palpi thickly clothed to the 

 apex : antennae faintly annulated. Fore wings — more than twice as long as wide — milky 

 white, with ochreous fawn-coloured streaks or reticulations : the appressed costal fold at the 

 base in the male is ochreous faw^n-colour ; and there are numerous pale streaks of the same 

 colour along the costa, the first acutely angulated beyond the middle and sometimes forming 

 with a straight horizontal line towards the base an arrow-shaped mark ; two or three others 

 on the costa towards the apex assuming the form of the Greek y, the tails pointing outwards 

 towards the very oblique apical margin : in some varieties the markings are so much blended 

 as to be scarcely traceable, giving to the wing a more suffused appearance : the apical margin 

 is narrowly ochreous fawn-colour, with a line of black scales at the base of the ciha, and a few 

 black dots above and within the anal angle : underside brownish fuscous. Hind wings pale 

 brownish grey ; cilia milky white. 5 ^. Expanse of wings 13-20 millims.
