Appendage s. — Superior and inferiors of same length, 3'5 mm., somewhat

Larval Types: c??, Coll. Tilly ard. (Waroona, Jan. 4th, 1912.) 

 From the figures and description there can be no doubt that the unnamed 



" ^schnine-larva C " described by Dr. F. B,is on p. 446 of his " Fauna 



S.-W. AustraJiens^^ belongs to this species.

AUSTEO^SCHNA ATRATA, Martin. 



A single male of this fine species was found by me emerging at Guy 

 Fawkes, N.S.VV., on Dec. 22nd, 1911. The following is a description of the 

 exuviae : — 



Larva (c^). — 'Total length 37 mm., greatest breadth 8 mm. across eyes. 

 Head. — 6 ram. ; eges large ; postocular lobes well rounded, very dark, with 

 a pale crenulated outer patch. Labium. — Mentum 6 X 5"2 mm., reaching 

 only just to mesocoxse, where it narrows to 3"3 ram. (Plate 6. fig. 7). Median 

 lobe very flatly bilobed, carrying a row of hairs, a pair of large tubercles and 

 a pair of smaller tubercles, the latter being closer to the median depression. 

 Lateral lobes of medium breadth, tips truncate ; outer apical angle rounded, 

 inner toothed ; inner margin crenulated ; movable hook 1*6 mm., sharp 

 (Plate 5. fig. 13). T h o r a x. — Prothorax 2x5 mm., with very blunt dorso- 

 lateral and two pairs of sharper sublateral spines. Meso- and metathorax 

 strongly built, with very flat lateral spines ; wing-cases S'D mm. Legs very 

 large and strongly built, very dark, slightly spotted ; hind femur 8x1-2 mm. 

 A b d o m e n. — Of the usual shape, very rounded above ; no dorsal spines ; 

 lateral spines on 5-9 ; very small on 5, medium on 6-9. Appendage s. — 

 Superior and inferiors 3 mm., somewhat hairy, strongly pointed, tips slightly 

 incurved. Involucres : cJ superiors 1"2 mm., pointed ; c? inferior 0*7 mm., 

 broad, bluntly rounded (Plate 7. figs. 8, 20). 



Larval Type: S, Coll. Tillyard. Guy Fawkes (Ebor), N.S.W., 

 Dec. 22nd, 1911. 



Easily distinguished from all other known larvse of the genus by its broad 

 massive labium with two pairs of median mental tubercles and its exceedingly 

 large legs. 



Habitat. This somewhat rare species is confined to the mountains of 

 Victoria and N.S.W. I have taken it at Alexandra, Vic. ; on the Blue 

 Mountains and at Guy Fawkes, N.S.W. Although the dead specimens
