ANNALS OF THE QUEENSLAND MUSEUM, No. 2. 23 
66. Pristliesancfius dorycus, Boisd. Voy. Astrol. Ins. 2, p. 644, 
2, pi. ii., fig. 22 (1835). Loc : St. Joseph Eiver (A. C. English). 
Note. — The four examples referred to this species illustrate its variable nature, 
already alluded to by Stal (op. cit., p. 17.) In the case of one of two female 
insects, the thorax and post-ocular portion of the head arc pale chestnut. In that 
of two males, the same colour prevails in these regions, and also at the apex of 
the corium ; but the head (including the rostrum) anterior to the insertion of the 
antenna?, tne tubercles on the fore-lobe of the pronotum, and the venter are yellowish- 
white. Possibly, however, the latter two insects represent a distinct species. They 
measure but 15 mm. in length. 
67. Euaqoras dory cm, Boisd. Voy. Astr. Ins. 2, p. 645, pi. ii., fig. 
21 (1835). "Loc. : St. Joseph River (A. C. English) ; Milne Bay (C. 
Hedley); St. Aignan (5-7-1891) ; Taputa, Chad's Bay; and Roko. 
Note. — The New G-uinea representatives of this species agree in every particular 
with examples from Cairns, North-east Queensland. 
68. Polydidus armatissimus, Stal. O.V.A.F., 1859, p. 376, i. Loc. : 
Fergusson Island (A. C. English). 
Note. — Stal records the occurrence of this insect in the Philippine Islands, in 
China, and Ceylon. The Queensland \Iuseum possesses an example also from 
Herberton, North-east Queensland. 
69. Velitra rnarginata, Signoret. Ann. del. Mus. Civ. di. St. Nat. 
vol. xv. 1880, p. 544. Loc: St. Joseph River (A. C. English); 
Laloki River ; Fairfax Harbour. 
70. Sastrapada novcdguinensis, sp. nov. Female : Allied to the 
common Queensland species, S. australica, Stal ; but thus distinguished 
therefrom. S. novceguinensis is relatively narrower, with more elon- 
gated legs ; the prothorax is much longer ; the postero-lateral angles 
support sharp-pointed tubercles ; there are small teeth present on that 
portion of the outer wall of each fore acetabulum which extends as 
ridge to the hinder margin of the prostethium ; there are three or 
four ill-defined light fuscous vittse along the sides of the head and 
thorax, instead of the single fuscous vitta along each side of the pro- 
stethium. The two sub-contiguous vittse on the venter are also replaced 
by centrally- situated spots, one on the anterior border of each segment.
