420 Mr, Ambrose Quail on 



with one seta located on small posterior subsegment. Below 

 the antetrapezoidal the supraspiracular tubercle has one 

 long, one short, seta. The spiracle is below the supra- 

 spiracular tubercle — not on edge of intersegmental mem- 

 brane as in adult larva; posterior to the spiracle are 

 remote subspiracular sette ; below spiracle is an anterior 

 swelling Avith one seta; a subventral swelling with two 

 seta3. Abdominal 2 as 1 without the abnormal anterior 

 trapezoidal tubercle. 8, 4, 5, 6 have four hairs at base of 

 abdominal feet. 7, 8 as 2. 9 has two dorsal tubercles, 

 two subdorsal each with one seta, but the seta of one 

 subdorsal tubercle is long, that of the other is short. On 

 posterior edge of are two lateral tubercles with one seta 

 each, and a subventral tubercle with two setse. 



Abdominal feet have terminal hooks incomplete on 

 outer side, otherwise as in adult. Claspers have terminal 

 hooks only on inner side. 



Tubercle hairs have minute thorns. Skin covered with 

 minute pimples not so distinct as on P. uinhraculata. 



Figs. 13 and 14, PI. V, are from a larva, probably half- 

 grown, described in a paper published in " Proc. Roy. Soc. 

 Queensland," vol. xv, with illustrations; length 1^- inches. 

 A second larva about half-grown, length -|^ inch, differs 

 only in the colour being rather yellowish than red; I 

 suspect the colour of the larvic assimilates to the colour 

 of sap-wood in which they live. I note the smaller 

 specimen has spiracles distinctly on segment. I could 

 not discover subdorsal intersegmental thoracic hairs. Black 

 concavity of scutellum has two hairs, one very slender. 



Adult larva, length 2§ inches. 



Subspiracular tubercles of first abdominal segment are 

 not coalesced. Supraspiracular tubercles have one long, 

 one short setce. Spiracles are on anterior edge of seg- 

 ments if not actually on the intersegmental membrane. 

 Tubercles of abdominal 9 as before described. Abdominal 

 feet have two rows of terminal hooks which form a com- 

 plete margin, stems of first row of hooks almost reach 

 second row. Claspers have terminal hooks on inner side 

 only. 



Black concavity of prothoracic scutellum has one hair 

 only. Tubercle setae smooth. 



Most larvse have tubercles with definite area round the 

 base of seta, but none of the larvte of C. virescens have
