(Hi.i. — Til 1898, as quoted above, I descinbed and figured an 

 Argiopid, for whicli I proposed the name PoJtys vndtifiihercti- 

 h(ti(s. In tlie Girault collection there are two immature speci- 

 mens which, although different in abdominal ornamentation, 

 and having very microsco|)ic tubercles, I do not feel justified 

 in describing as new. Each of these specimens has a prominent 

 coniform tubercular projection at the summit of the abdomen 

 as in I'. f)iiiJtitiihevcnJi(tn;i, and numerous tiny tubercles dis- 

 tributed over its upper surface and sides, in much the same 

 manner as in the type of my Cooktown species. If the stu- 

 dent will compare fig. 43, pi. xxiii., given herewith, with that 

 quoted above, he will note both similarity and difference. In 

 the two specimens under discussion there is a large rich 

 brown longitudinal bar running down the middle for fully two- 

 thirds the length of the abdomen ; at its posterior extremity 

 it is joined by a concolorous transverse bar, the two thus 

 forming an inverted capital X. Both bars are somewhat wavy 

 in outline, and the apex of the pi'ominent abdominal tubercle 

 is slightly cleft. It is quite possible that the form under 

 review may be a distinct variety of P. imdtituherciiJutus, or 

 even an undescribed species, but as the larger of the two ex- 

 amples in front of me is probably only about half-grown, and 

 does not, of course, exhibit an epif/i/nKm, it is better to let the 

 matter remain in abeyance for the present. 



Hah. — Gordonvale, two specimens, both immature ; the 

 smaller one w^as collected by "sweeping" at top of coastal 

 range, at 1,500ft., May 29, 1913, and the lax'ger from an orb- 

 web in forest, August 31, 1912.
