138 FIORHSTIA KEWENS1S. 



rounded convex ; pure white and composed externally 

 of a closely felted material which at the cephalic 

 extremity extends in woolly filaments. Larval exuviae 

 at cephalic extremity, yellow or yellowish brown, are 

 often covered by the felted secretion. The removal of 

 the felted secretionary covering reveals the highly 

 chitinised exuviae of the second-stage female, which are 

 of a pale castaneous colour, or sometimes yellow or dull 

 crimson. At the posterior extremity of the second 

 exuviae (fig. 17 below) is a transversely ovate valve which 

 affords a means of escape for the imprisoned larvae. 



Long. '75 1 mm. 



Adult female elongate; much smaller than the insect 

 of the previous stage, and is completely enclosed with- 

 in the moulted skin of the latter. Antenna with 

 three long spiny hairs. Spiracles encircled by minute 

 parastigmatic glands. Pygidium (fig. 17 above), without 

 circumgenital glands or tubular spinnerets, is furnished 

 with about eight long spiny hairs at the margins, and 

 four to six others on the dorsal area. Anal opening- 

 central. Position of vaginal opening not ascertained. 



Puparium of male very elongate, without carinae, 

 rounded convex ; widest immediately behind the larval 

 exuviae, and almost pointed at the posterior extremity. 

 A number of woolly filaments occur at the anterior 

 extremity as in the puparium of the female. Larval 

 exuviae at anterior extremity pale yellow or light 

 castaneous. 



Long. "50 *70 mm. 



Pupa yellow, with black eye-spots. 



Larva somewhat elongate, has six-jointed antennae, 

 of which the first joint is very broad ; two, three, four, 

 and five equal, six about as long as the three latter. 

 Formula 6, 1 (2, 3, 4, 5). Along the margin at the 

 sides are a series of six to seven chitinous discs sur- 

 mounted by a minute spine. 



Habitat. On Howea Forsteriana, intemperate house 

 at the Royal Botanic Gardens, Kew, March, 1898.
