GENUS CRYPTOPHASA. {CryptophnsidiU?) 

 Cryptophasa, Lewin, Lepid. Ins. N. S.Wales, p. ii (1805); 

 Duncan, in Jardine's Nat. Libr. Exot. Moths, p. 1 17 (1841). 



The antennce are pectinated nearly to the tips in the male, l)ut 

 are simple in the female. The proboscis is obsolete, and the 

 palpi are cylindrical, curved upwards, and pointed. The wings 

 are glossy, with short fringes. The larva has sixteen legs, and 

 is long and cylindrical. It bores into the trunks of trees, and 

 emerges at night to provision its burrow with leaves, on which 

 it feeds. 



These Moths, though now referred to the Ttnecs, more 

 resemble Bombyces or Noctucc in size and aj^pearance ; and 

 they are among the largest Tincce known.
