BV R. .T. TILLYARD. 429 



To the description and figures given, it is only necessary to 

 add that, although the type male has three apparent radial 

 sectors on each forewing, the second male in my collection shows 

 only two; while, in the left forewing, one of these (R 5 ) becomes 

 attached to M near the forking of the latter. 



T y p e : Eolotype <J, Coll. Tillyard; Stradbroke Island, Q. A 

 second male in my collection, from the same locality.

£. Total length, 23 mm.; abdomen, 11 mm.; forewing, 21mm.; 

 hindwing, 18 mm.; expanse, 17 mm. 



Very close to //. fulva (Till.), from which it differs in the 

 following points :— General colour pale ochreous, with a black 

 line behind the eyes in the suture between head and prothorax. 

 Wings very transparent, almost colourless, the veins very pale; 

 no tinge of mauve on them at all. Antennae with the basal 

 joints pale yellowish-brown, the rest gradually darkening to dark 

 brown towards tip (those of H. fulva are of a uniform rich orange- 

 brown). Appendages rather short, of normal forcipate type, but 

 somewhat broader than those of H. fulva when viewed laterally. 



$. Total length, 25 mm.; abdomen, 18 mm.; forewing, 30 mm.; 

 hindwing, 27 mm.; expanse, 66 mm. 



Closely resembles the male, but much larger and stouter. No 

 dark band between head and prothorax. Wings very broad, 

 with 7-8 descending branches from Rs, instead of 5-6, as in the 

 male. Sand-plough strongly cultriform in shape, the angle being 

 placed dorsally; the two gonopods very short and inconspicuous.
