Q.: Brisbane — N.S.W.: Sydney, Bulli, Mittagong, Bathurst — 

 Vic: Gisborne, Dimboola(Lyell) — ^Tas.m.: Launceston, George's 

 Bay — S. AusT.: Mount Lofty — W. Aust.: Albany, Perth, York; 

 in October, November, January, March, and April. The species 

 varies a good deal, even in form of wing; some specimens may be 

 said to have the costa moderately arched, others slightly; the 

 Bathurst example is the largest (9, 16 mm.), with the longest 

 palpi, and has the terraen of forewings sinuate, but I am unable 

 to regard it as distinct; no two specimens are quite alike. I 

 was, however, accustomed to meet with the species commonly, 

 and never had any doubt of its identity. I mention these par- 

 ticulars because they contribute to the ditficulty of what follows. 



I have bred this species from the larva under circumstances so 

 singular that I cannot interpret them to my own satisfaction, 

 and therefore give tlieui at length in the liope that local workers 

 will make investigations on the subject. 1 found some extra- 

 ordinary larvae, of which I made the following description : Larva 

 apodal, slender, cylindrical, head small, semicircular, segments 

 2-4 (especially 2) much swollen, all incisions well-marked, anal 

 segment pointed and with short spines towards apex; positions 

 of all legs indicated by feeble sucking-bases; ordinary spiracles 

 absent, but two dorsal spots on eacli of segments 2-4 greatly 

 enlarged and furnished with a longitudinal .slit; rather dark 

 fuscous, reddish-tinged; head and back of segment 2 blackish, 

 segments 2 and 3 with a i-eddish dorsal line; large dorsal spots 

 of segments 2-4 light ochreous; all other spots obsoletely repre- 

 sented by slight depressions ; anal segment blackish towards 

 apex : mines a long rather broad gallery down leaves of a large 

 coarse sedge like plant growing in dry bush at Botanj' Ba}-, in 

 August; the last three segments of body are held at a right angle 

 and used as a lever for motion within the gallery; pupation out- 

 side the mine, amongst refuse. From these larvae I bred one 

 rather small and pale female specimen, with somewhat less 

 ferruginous suffusion than any other example possessed, fore- 

 wings hardly dilated posteriorly, costa slightly arched : I have a 

 captured male from Sydney which hardly differs from it, and
