78 Lloyd's natural history. 



silvery grey, more or less speckled with black and white, and 

 with coppery-brown bands ; on the fore-wings is a large 

 coppery-brown blotch, enclosing two oval transparent spots, 

 giving the moth some resemblance to the Saticrjiiidce. The 

 habits of the larva, however, more resemble those of the 

 Psychidce^ for it constructs itself a case composed of fragments 

 of wood and grains of sand, and the pupa is enclosed in a 

 large silken cocoon. 



Perophora (Harris) is another American genus, which is 

 found as far south as Buenos Aires. The type of the genus, 

 P. viehheiineri (Harris), is also its most northern repre- 

 sentative, being widely distributed in the United States, 

 though far from generally common. It is a stout-bodied 

 moth, with strongly-pectinated antennae, and measures about 

 an inch and a half across the wings, which are rather short and 

 broad, the costa of the fore-wings being arched, and the tip 

 moderately hooked. It is reddish-grey, dusted with black, 

 with a dark oblique stripe running from the costa of the fore- 

 wings, before the tip, to beyond the middle of the inner 

 margin of the hind-wings ; there is also a black discoidal spot 

 on the fore-wings. The habits of the larvae oi Perophora are 

 curious. They construct for themselves a tough case of 

 leaves, about an inch long, and open at one end. These 

 narrow open cases are so characteristic as to be instantly 

 recognisable as belonging to this genus.
