remaining segments they are separate; and there is an 

 additional tubercle with one seta above the base, and also 

 a fourtli hair on the base of the abdominal feet. There 

 is also an additional subdorsal tubercle with one seta on 

 the ninth abdominal segment : this may indicate the 

 morphological character of the two supra-spiracular seta?, 

 viz. really two separate tubercles which have coalesced. 

 Tlie subventrtil tubercles have two setpe. 



Ventrally, the abdominal feet have several rows of 

 rather weak hooks which form a complete terminal margin, 

 the claspers have several rows of weak hooks on inner side 



The skin is covered with fine hair. The tubercle setas 

 have minute thorns. 



Larva 8G days old. 



Not quite so slender, length about f inch. I noted the 

 spinneret is long and slender ; and that ventrally anterior 

 to each prothoracic leg there is a single hair, which is not 

 duplicated on the meso- and meta-thorax. The distribution 

 of hairs on the ventral surface is, one hair near base of 

 each leg on the posterior margin of the thoracic segments; 

 abdominal segments 1 and 2 correspond, the hairs being 

 inner to the two sub-lateral tubercles. 3, 4, 5, 6 have the 

 hairs on inner side of the abdominal feet. 7-10 have 

 corresponding hairs. 



I noted also that the middle and the inner hairs of the 

 second series of the prothoracic scutellum have a large 

 circular black area around the base of each. 



Larva 93 days old. 



I note the anal segment viewed laterally has one dorsal 

 tubercle, one anterior subdorsal, one posterior subdorsal, 

 above the anal orifice, three similarly situated below the 

 anal orifice, and four setse on base of claspers, one of 

 which is anterior and above the other three. The terminal 

 hooks of abdominal feet are numerous and form a com- 

 plete margin, the terminal hooks of claspers are strong on 

 inner margin, but weak posteriorly. 



Larva 135 days old. (PI. V, tigs. 14, 15, IG.) 



Considerably more robust, length from f to 1 inch. 

 The larvae appear to increase rapidly in length in their 

 early days, and subsequently increase more in bulk, and
