ODONESTIS POTATORIA. (Frontispiece.) Drinker Moth. 

 In this species the male is reddish-brown, the anterior wings 

 having a patch of ochre-yellow at the base, and the disc 

 slightly suffused with that colour; a rust-coloured line 

 extends from the tip to the inner edge ; there is also a faint 

 line near the base, and another towards the hinder margin ; 

 on the disc are two white spots, one of them stained with 

 yellow ; the inferior wings are unspotted, but there is an 

 indistinct transverse streak on each, darker than the surface ; 

 the female is of a pale ochre-yellow, sometimes nearly white. 

 The caterpillar has two long, conical tufts, and on each side 

 a series of black velvety spots, followed by a line of yellow, 

 and, beneath these, tufts of white hairs. Like many of the 

 tribe, it rolls itself into a ring when alarmed ; it feeds on a 

 variety of grasses, and is plentiful in many situations.
