especially noted the identity of the three separate setae at 

 base of abdominal feet, and the position of the tubercles 

 on 9th and 10th abdominal segments. 



Larva 18 days old. 



Length ^-^ inch, very slender in proportion to length. 

 Pale cream colour, head pale brown. As regards the 

 number and position of tubercles on the thoracic and 

 abdominal segments; these correspond with P. ccrvinata 

 at fifty-one days old, except that the subspiracular tubercles 

 of first abdominal segment are not coalesced. It may be 

 "worth while to point out that the anterior dorsal tubercles 

 of the meta-thorax are anterior to the supraspiracular 

 tubercle, whereas on the abdominal segments the anterior 

 trapezoidal tubercles are above the supraspiracular in 

 position. 



The hooks of the abdominal feet appear to be one 

 strong inner row, and one outer row of minute points (or 

 spines). Four separate hairs at base of abdominal feet. 

 The entire skin is covered with minute pimples, but 1 

 cannot detect hairs as on the skin of P. ccrvinata. The 

 tubercle setae are minutely thorny. 



Larva 39 days old. 



Length -| inch. Head pale mahogany brown. Eighth 

 abdominal segment pale, all other segments dark, of a 

 rather greenish shade. 



Subspiracular tubercles of first abdominal segment are 

 not coalesced. Cannot detect hairs on the "pimples" 

 which cover the skin. Abdominal feet have a strong 

 inner row of hooks, and several rows of minute spines. 

 Claspers incomplete posterior terminal margin. 



Jjarva 81 days old. 



Length | inch. Colour dark oiley greenish. Coalesced 

 subspiracular tubercles on first abdominal segment. Can- 

 not detect hairs on the " pimples," Claspers incomplete, 

 marginal hooks p< sterior. Setae thorny, 



Imngo labelled Llhamma signata, Walk., var. umhra- 

 culata, Gn., in the British Museum collection. Described 

 by E. Meyrick, " Trans. New Zealand Institute," vol. xxii, 

 with synonymy, as P. mnlraculata. I am convinced that 

 P. umhraculata and P. signata are specifically distinct, 

 and have noted a difference in the scale structure of the
