DESCKIPTIONS OF AUSTRALIAN ^SCHNIN^. 17 



bases of femora brownish beneath ; all tibise with two rows of short even 

 cilia, the inner row on protibiag fine and closely set like a comb. 



Abdomen. — 1-2 swollen, 3 scarcely pinched at all, 4-10 cylindrical, 

 7-10 only very slightly widened. Genitalia of segment 2 with the spines of 

 anterior lamina bluntly pointed, the anterior hamuli not pointed, irregularly 

 rounded and lobed, carrying hairs on posterior border ; posterior hamuli 

 small, placed vertically against the tergal folds, tips carrying hairs ; auricles 

 large and rounded, with posterior border carrying a set of small spines or 

 teeth ; tergal folds prominent, oval in ventral view, with fairly denticulate 

 margins; in lateral view they rise up posterioidy to a fairly sharp pro- 

 minence ; penis with a pair of long curved end-filaments, projecting ventrally 

 far beyond the level of the folds ; sheath of penis placed completely in front 

 of penis and scarcely enclosing it at all (fig. 4, also Plate 9. figs. 10, 21). 

 Colour. — 1, brown ; rest dark brown marked with green (yellowish in 

 immature specimens) as follows : 2, a touch of green on each side of dorsum, 

 auricles yellowish green ; 2-8 with very distinct transverse central carinse ; 

 3-7 with a pair of basal dorsal lines reaching to carina, a pair of sublateral 

 spots, and a pair of central spots wider apart, lying just distally from carina ; 



8 with similar markings, but basal dorsal lines short, and central spots 

 enlarged with a pair of lines covering the apical three-fifths of the segment ; 



9 with basal lines, a pair of very small basal sublateral spots, and a pair of 

 fine dorsal lines ; 10, a pair of thicker dorsal stripes. 



Appendage s. — Superior 1'2 mm., thin, very slightly waved, blackish ; 

 inferior 2*3 mm., large, trifid ; the central tip truncate, projecting far beyond 

 superiors ; lateral tips small, rather pointed, and upturned so as nearly to 

 meet tips of superiors ; colour semitransparent brown in centre, shading to 

 blackish along edges (Plate 9. figs. 8, 9). 



Types : c? ? , ('oll. Tillyard {S type, Katoomba, Nov. 16th, 1912). 



Larval Type*: ? unique, Coll. Tillyard. 



Habitat. Blue Mountains, N.S.W., from 2000-4000 feet; especially around 

 Katoomba (above 3000 feet), October and November. 



There are very few records of captures of this very rare insect. In 

 November, 1903, Mr. G. A. Waterhouse captured two females at Leura (one 

 of these is the type ? , the other is said to have been sent to Cambridge, 

 England). On Nov. 9th, 1908, Mr. K. Brown discovered a^larval skin and 

 newly emerged ? imago at the Leura Cascades. They were just about to 

 be washed away by the quickly rising water during a heavy storm. Each 

 year a sharp look-out is kept for it by collectors, bat no further captures 

 were made until Oct. 6th, 1912, when Mr. Gr. J. Waterhouse captured 

 another ? in his garden at Woodford (2000 feet). On Nov. 10th, 1912,, 



* The term " Larval Type " is here used to indicate the actual specimen (be it exuvi* or 

 full-fed nymph) from which the description is made. It is, of "course, not a "type" in the 

 sense of fixing the species.
