DESCRIPTIONS OF AUSTRALIAN ^SCHNINJS. 55 



long as in A. multipunctata, reaching just to end of 9. Involucre of male 

 inferior appendage more pointed. Labium and appendages apparently very 

 similar to those of A, multipunctata. 



Habitat. Mountains of South Australia and Tasmania, especially the west 

 and north. I have no definite records for Victoria or southern N.S.W. ; all 

 my captures at Alexandra and Mount Kosciusko w^ere A. multipunctata. It 

 occurs, however^ in company loith the latter, at Gruy Fawkes, N.S.W. 

 (4000-5000 feet), and I was very pleased to add a single male taken at Hill 

 Top, N.S.W., also in company with A. multipunctata, to my records on 

 March 30th last. Now that I have long series of both species, all doubt as 

 to their distinctness is removed. The chief differences have been pointed 

 out by me in a former paper*. Their occurrence together in the same 

 localities places the matter beyond the region of doubt, as they can no longer 

 be regarded as distinct geographical races. 



Types : r^ Coll. Selys, ? Coll. Martin. (Localities not stated.) 



AUSTRO^ESCHNA UNICORNIS, Selys. 



Only two exuviae of this very beautiful species have been fuund. The first 

 was found by me emerging on Jan. 13th, 1912, at Gruy Fawkes (Ebor), 

 N.S.W. ; the second was taken by Mr. G. A. Waterhouse at Stanwell Park, 

 N.S.W., Feb. 22nd, 1913. Both are females, and both belong to race pulchra, 

 Tillyard. As this race was originally described by me from Lily Vale, near 

 Stanwell Park, I have fixed Mr. Waterhouse^s specimen as the larval type. 



Larva (?). — Total lengtli 31 mm.; greatest breadtli 7 mm. across 

 abdomen at 7. Head. — Smallish, 4*8 x 6"5 mm.; postocidar lobes not 

 prominent, smooth, rounded ; front projecting, narrow, 2 mm. Labium. — 

 Mentum 7 x 3'5 mm., very long and narrow, reaching well up to mesocoxse^ 

 where it is narrowed to 1'7 mm. (Plate 6. fig. 4) . Median lobe very flat, slightly 

 bilobed, carrying two small tubercles. Lateral lobes narrow ; tip rounded, 

 nodding ; inner margin finely crenulate ; movable hook thin, sharp, 1'2 mm. 

 (Plate 5. fig. 3). Thorax. — ProtJwrax l'5x4'5 mm., with one pair of 

 blunt dorso-lateral and two pairs of sharper sublateral spines. Meso- and 

 metatliorax smooth, with slight indications of incipient spines ; iving-cases 

 ^•b mm. Legs short, fairly strong, dark brown, much spotted with pale 

 brown. Abdomen shaped as usual, with no dorsal spines ; lateral spines on 

 5-9, those of 6 small, 7-9 medium ; 5 with a tiny spine. Appendage s. — 

 Superior 2'9, inferiors 3 mm., shaped very much as in A. mnltipvnctata, but 

 less hair}' ; tips of inferiors sharper and slightly bent inwards (Plate 7. 

 figs. 4, 16). Involucres, ? , 0'4 mm., sharp. Ovipositor large, reaching 

 loell beyond end of 10, and curving up between inferior appendages 

 (Plate 6. fig. 10). Colon r. — -Hark brown, mottled with paler brown ;
