therefore is left out, and the larva hauls them gra- 
dually in as it consumes them. The pupa state 
continues for thirty-eight days, the moth appearing 
in the end of February. It frequents banks of 
rivers, ponds, and deep gulleys; these being the 
places where the trees it feeds on are usually 
found. 
C, PuLTEN-E. — Wings silvery-white, the anterior pair \rith 
three small black spots in the middle and a marginal 
row at the extremity ; hinder wings black in the male, 
white in the female, with a series of angular black marks 
at the hinder margin : abdomen with a square spot of 
bright red towards the base. Expansion, male one inch ;

The larva bores doAvnwards a cylindrical chamber 
in the centre of the stem of Pultencea villosa, Willd., 
having the entrance arched over w^ith a fabric of 
web and excrement, under which, having taken its 
food thither in its nightly excursions, it feeds during 
the day in secret security. 
Lewin informs us tliat all the larv» of the genus 
Crjptophasa seal themselves in by an agglutinated 
covering across the cell or chamber where they 
transform to pupee, through which, however, the 
moth can force its way from below; yet it is a 
strong bulwark against external foes, and effectually 
supplies the purposes of the old covering at the 
mouth of the cell, which falls off soon after the 
larva's final retirement. The group is named Cryp- 
tophasa, from the secret and secure manner in which 
this new and evidently natural division of moths
