dorsal stripe clearly defined, either of a shade of green^ 

 darker than the ground colour, or else purplish-brown [ 

 subdorsal lines faintly grey; raised dots minute, black- 

 ocellated spots large, white, encircled with black ; spiracles 

 minute, brown ; ventral surface uniformly of a paler shade 

 of the ground colour. (G. T. Porritt.) 



August, September, and sometimes October, on Bahola kali 

 (saltwort), feeding on the shoots and seeds, under a silken 

 web ; but when young burrowing into the shoots, and giving 

 their tips a withered appearance. Abroad said to feed also 

 on Salicomia hcrhacea and Atnpla: hortensis. 



Pupa about two-fifths of an inch long, evenly rounded 

 broadest at the thorax, and tapering gradually to the anal 

 point ; the whole surface semi-translucent and polished, and 

 all the parts well defined ; eye, leg, and wing cases bright 

 green ; thorax and abdominal segments yellow ; abdominal 

 divisions brown ; and a distinct green "line, which shows 

 through the translucent covering, extends through the dorsal 

 area. (G. T. Porritt.) 



In an ovate cocoon of silk mixed with grains of sand, 

 lying loose in the sand tlirough the winter, and indeed for 

 ten months of the year. 



The moth is not often captured, its colour and faint 

 markings render it so accurately like the sea-sand, prostrate 

 on which its usual food-plant grows, that a keen eye is 

 required to distinguish it ; but the larva is not hard to find, 

 or to rear, and most of our cabinet examples are obtained in' 

 this manner. So far as this country is concerned it seems t& 

 be restricted to the sea-side, and there to the loose sands a 

 little above high-water mark ; and to be found only in the 

 Southern and Eastern Counties ; but it must surely be, in 

 some suitable localities, overlooked. Common in Hayl'ing 

 Island and other parts of the coast of Hants, and found in 

 similar situations in Kent, Sussex, Dorset, Essex, and Suffolk, 

 but so far as can be ascertained not known elsewhere in these
