 latter minutely spinose ; wings whitish ; veins white ; stigma pale

Eab.—" New South Wales." 



Obs. — This description was overlooked by me until recently ; 

 and Walker does not mention the species in his " Notes" published 

 in 1874. The above-described does not appear, from the descrip- 

 tion, to be identical with any known species, but may possibly be 

 the same as B. pictijyes, Sk. 



Genus Scatopse, Geoffroy.

 Sk., P.L.S.N.S.W., III. (Ser. 2nd), p. 1383, pi. xxxix., fig. 9, 1888. 



Obs. — " I agree with you in thinking that your Scatop)se longi- 

 jjennis is the same as the common European S. notata. I have 

 received numerous specimens from New Zealand, which I cannot, 

 distinguish from *S'. notata. They are probably imported in ships." 

 — Osten-Sacken, in litt., 18th May, 1889.
