 ently rare. 



Genns Ichthyuea, Hiibn. 

 316. /. anachoreta^ Fabr. 

 Sikhim, 5,500 feet. 1 reared two males from pupas taken at Tukvar. 

 The cocoons were formed of the leaves of Salia; halnjlonlca drawn 

 together, on which tree the larva probably feeds. The moths emerged 

 in November. Mr, Elwes has specimens taken in February and May.

 wing irrorated with fuscous ; a pale oblique sulibasal line bent outwards 

 en median nervure ; a pale oblique slightly sinuous antemedial line ; 

 a pale oblique line across the apical area angled below vein 4, then 

 inwardly oblique and sinuous to inner margin ; a dark brown patch on

 Sikhim and Bhutan, 1,800 to 5,500 feet. I have taken the larva of 

 this commonly feeding on the leaves of Salix Jiah/flonica, a non-indigenous 

 tree. It occurs in the perfect stage in June, July, August and Octo- 

 ber. This species is variable, two males and two females have the 

 medial outwardly-curved line replaced by an oblique line from the 

 middle of the antemedial line to the postmedial line at the inner 

 margin. This is possibly the form described by Mr. Moore as I.ferru- 

 ginea from North-east Bengal.
