 broadly webbed and furnished with large dilatations, I refer these 

 larvce provisionally, though not Avithout doubt, to the present species. 



Body twice as long as broad ; spiraculum lateral, on the left side, 

 nearer the base of the tail than the end of the snout. Beak strono-, 

 upper mandible transparent, lower black ; lips much developed, their 

 inner surface lamellated. The adhesive ventral apparatus represents 

 a disk the anterior third of which is cut off ; it is situated imme- 

 diately behind the mouth, and its posterior border corresponds to the 

 vertical of the spiraculum ; the lateral and posterior borders are free 

 to a slight extent. The tail measures once and two thirds or once and
