_Glenurus pulchellus_ is the commonest species about the coast, with a wing expanse of about 2½ inches; its general colour is chocolate brown, mottled and marbled with lighter tints; the fore wings are speckled with black; the apical portion of the hind pair deeply blotched with chestnut brown, encircling a white patch, with a second smaller one nearer the extremity. _Glenurus falsus_ is a shade smaller; the fore wings darker; and a single dark patch on the hind wings. _Glenurus striola_ is a slightly larger species with semitransparent wings, marked on the posterior margin of the hind pair with a narrow light brown stripe. I found this species very plentiful in some swampy flats near Brisbane, Q., in October, where they were resting on the rushes. _Glenurus fundatus_ is our largest species, often measuring up to 4 inches across the wings, and is of a general uniform mottled grey tint spotted with brown; it is common along the coast in North Queensland. _Glenurus circuiter_ is easily recognised from all the others by the shape of the fore wings, which are broadened to the tips, cut out behind at the extremities, and both pairs are irregularly blotched and spotted dark brown, giving it a very handsome appearance. _Glenurus erythrocephalus_ has semitransparent wings, elongate and rounded at the tips, the fore pair thickly covered with spots and blotches of dark brown, the hind pair usually only marked with three spots, but the spotting is very irregular and variable. It comes from the more northern parts of N.S. Wales and Queensland. * * * * * The ASCALAPHIDES are all moderate-sized, clear-winged insects with a stigma toward the tip, and curious long slender antennae clubbed at the tips; they might be likened to dragon-flies with butterflies’ heads. _Suphalasca sabulosa_ measures about 2½ inches across the wings; the head and thorax are fringed with fine hairs, the stigma on the wings black. It is generally found on bush land clinging to a grass stalk or twig, with the wings folded down, and the slender body sticking out at right angles. I have found the larvae living under the dry bark attached to dead tree trunks, their short hairy bodies covered with tufts of stout bristles, their large jaws pointing upward; and from their situation they probably capture the large sugar ants. In captivity they would remain for days resting against the side of the box without any movement, and lived for several months without taking any food, and finally formed a round cocoon. The female places her eggs in a double row along the edge of a blade of grass, and the young ones, when they hatch out, sit in the bottom of the eggshell, all head and jaws, waiting for something to turn up, and must often undergo long fasts.
