around tlie wing-border strongly outlined and thickened witli 

 black. The whole of the forewing is heavily marked with 

 irregular grevish-black streaks, spots, and blotclies, tending to 

 form oblique fascia* across the wing. Ptpvostiyma well-formed 

 in both wings, spotted with black along costa. Tip of forewing 

 more evenly rounded than that of Sp. disseminafo, and costal 

 area of same wing more abruptly dilated near the base; costal 

 cross-veins more irregularly placed, and much branched. Iliiid- 

 wimj not speckled, venation testaceous along Sc, R, and Rs, dark 

 grey to black on the rest of the wing: in 9, M,, M„, and the 

 three liranches of Rs above them, are provided with scales over 

 a moderate-sized area in the middle of the wing. 



[Note. -In figuring tlie two species of Spermopliorella, 1 have 

 omitted the short, bristly hairs whicli are present on all the 

 veins, in order to show up the venation more clearly.)

Hab. -One-Tree Hill, Brisbane: two males and two females, 

 taken on a hot afternoon, disturbed while resting on the face of 

 a cutting about half-way along the road to the summit. Sep- 

 tember. 



The four specimens captured were put separately into pill- 

 boxes alive. The same evening, both females laid a number of 

 stalked eggs, from twenty to thirty apiece. These were very 

 similar to those described for Sp. disseminata, but the eggs had 

 a slight greyish tinge. They hatched on the tenth day after 

 being laid. During the embryonic period, the eggs darkened 

 to a semiopaque grey, through which a double band of black 

 markings made itself visible on the developing larva. The young 

 larva, when hatched, resembled that of Sp. disseminata in size, 

 shape, and actions: but it was of quite a different colour, the 

 ground-colour being pale grey, with large blaci< .spots on alter- 

 nate segments. It would seem, then, that this larva inhabits 

 the darker rocks which are so common around Brisbane, and 

 probably preys upon Lepidopterous caterpillars, which feed on 

 the lichens of the rocks. I was unable to obtain suitable food 

 for my larvae, and they all died.
