DESCRIPTIONS OF AUSTRALIAN ^SCHNIN^. 53 



Ovipositor reaching to middle of 10 (Plate 6. fig. 11). Colour. — Blacky 

 with rich mottling of paler brown markings ; usually, conspicuous oval 

 dorsal spots on 8-9, sometimes a smaller one on 7. 



Larval Type: ?, Coll. Tillyard. National Park, N.S.W. ; emerged 

 January 6th, 1905. 



Habitat. This beautiful and graceful species is nowhere common, but is 

 very widely distribated throughout Eastern Australia and Northern Tasmania. 

 I have it from Mount Lofty Ranges, near Adelaide ; Cataract Gorge, Laun- 

 ceston, Tas.; Alexandra, Vic; Hill Top, Heathcote, National Park, Glenbrook, 

 and Medlow Bath (3400 feet), N.^.W. ; Guy Fawkes (4000-5000 feet), 

 N.S.W. ; Herberton (3000 feet), N. Queensland. The Herberton specimens, 

 taken by Mr. F. P. Dodd, differ somewhat from the type, having shorter 

 bodies and appendages, and might merit the rank of subspecies, though I do 

 not propose to name them until I obtain more material. 



Types : (^ ? , Coll. Martin ; Victoria (probably Alexandra).

This is undoubtedly the commonest species of the genus on the Blue 

 Mountains, N.S.W., and also in Victoria. I have kept a number of the 

 larvse in my aquaria, and succeeded in breeding out several. The general 

 account of the life-history given for A. longissima holds good also for this 

 species, but with the following important differences : — 



The perfect insect is the first of the genus to appear, my earliest record 

 being November 28th (Dorrigo), but they are seldom seen until the second 

 half of December. They remain on the wing until April. The larvse are 

 very different in appearance from those of A. longissima, being of a dirty- 

 brown colour. Instead of living on submerged sticks, as ^4. longissima does, 

 they hide in accumulated trash in the deep pools, or_, more frequently, cling 

 to the matted tangle of projecting roots and weeds that fringe the steep sides 

 of the pools. In such situations they are not uncommon. When dredged 

 they are usually slightly covered with sand or mud, especially on the 

 appendages, which are very hairy. They are rather inactive, and usually 

 feign death when handled. Their spines are small and harmless. The female 

 oviposits in twigs or matted roots along the sides of deep pools in the 

 mountain-creeks. 



Larva. — Total length 37 mm., greatest breadth 7' 5 mm, across eyes. 

 H e a d. — 5 mm., ocelli very prominent ; postocular lobes roughened, regularly 

 rounded. Labium. — Mentum 7-5x4 mm., reaching to between meso- and 

 metacoxse, where it narrows to 2 mm. (Plate 6. fig. 6). Median lobe some- 

 what projecting, bilobed, with a row of stiff short hairs and two small black 

 tubercles. Lateral lobes narrowed, truncate, outer apical angle well rounded, 

 inner one strongly toothed ; inner border distinctly crenulated, movable hook 

 1-4 mm., sharp (Plate 5. fig. 5). Thorax. — Prothorax 1-8 x 5*5 mm., with
