To the superfamily characters may be added the following as of only family or generic value: — Size very small; abdomen very slender, extending beyond the wings; petiolation of wings not clearly marked off by an indentation or angu- lation of posterior margin of wing; postnodals 5-6 in number, only normally 4 in the space posterior tc them,; pterostigma short, rhomboidal, covering a single cell; veins 1R2 and 1R3, together with some distal cross-veins, dis- tinctly hairy.

In forewing, there is a single oblique line formed between R and 1A by the following elements—(a) upper portion of arculus, (b) distal side of the open discoidal cell, (c) short distal side of subdiscoidal cell. In both wings, the anal-crossing, (Ac) is to be interpreted as a mere oross-vein impinging upon the vein 1A just after it leaves the posterior margin. A study of the tracheation of the nymphal wing indicates that at no time is any trachea present, and therefore this cross-vein cannot very well represent the previous crossing-over of such a trachea from the line of CuP to the posterior margin. It might, however, be interpreted as the homologue of the cross-vein which, in Kennedya and Permolestes, supports the downturned end of the primitive basal remnant of CuA from below. For a full understanding of the importance of the genus Hemiphlebia the Blackall Ranges, approximately 100 miles north of Brisbane. I have searched very large areas of suitable country in Eastern Australia for Hemiphlebia without success, except for the original locality discovered many years ago by Captain Billinghurst and recorded by Rene Martin (1904).— Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Royal Zoological Society of New South Wales; Royal Zoological S
