Queensland and New South Wales. I sopeda dolosa L. Koch. Voconia dolosa L. Koch, Arach. Austr. 1875, p. 648. L. Kocli described this species from two dried specimens in the Museum at Stuttgart, labelled " Australia" only. The differences by which he says it may be distinguished from I. insignis Thor., are that. " the clearly smaller median eyes of the front row are more than their diameter from the rear median," and the joining by a dark longitudinal marking of tbe two median pair of muscle-spots on the back. The latter feature seems a by no means uncommon variation in any species, whenever the back spots are specially well developed, and the former is almost universally the case with females of I. insignis Thor. I have therefore great doubts as to it being really a separate species; if it is, the joining of the back spots is its only distinctive character. The Horn Expedition had several specimens from Central Australia, both male and female, with back-markings as described, very flat cephalothorax, but front row of eyes equal, and I have similar from Victoria, otherwise the same as I. insignis. I sopeda su b d o l a Thor. Holconia subdola Thorell, Rag. Mai. e Pap. vol. iii. 1881, p. 304. Thorell himself describes this as a doubtful species, the only difference from Koch's description of H. dolosa being in the coloration of the back of the abdomen. From Cape York, N. Queensland.
