01? NEW SOUTH WALES. 196 



ochreous, lighter towards inner margin ; extreme costal edge 

 narrowly white ; a straight rather narrow white sub-costal streak 

 from base to apex, sometimes emitting posteriorly two or three 

 slender white streaks to costa, or partially confluent with the 

 white costal line ; a rather strong white, above black-margined 

 posteriorly, central streak on sub-median vein from base to hind- 

 margin, sending from its lower edge four rather broad parallel 

 branches to hindmargin, separated by very narrow ochreous lines 

 (sometimes sprinkle(J with blackish), lowest branch often strongly 

 blackish-margined ; an elongate-triangular white subapical spot, 

 resting on hindmargin below apex and on posterior third of me- 

 dian streak, more or less distinctly cut by two rather obsolete 

 ochreous (sometimes mixed with blackish) longitudinal lines; 

 below median streak a white line from near base to anal angle, 

 and a white line from base to before middle of inner margin ; 

 inner margin whitish towards base ; hindmarginal line fuscous, 

 marked with seven or eight black dots ; cilia white, extreme tips 

 and a parting line greyish-ochreous. Hind wings whitish-grey, 

 marginal line dark fuscous ; cilia white. 



Differs from its allies by its broader wings, white head, and 

 greater breadth of the white streaks on the branches of the 

 submedian vein. Common round Sydney and Parramatta, es- 

 pecially in rather damp places ; also near Melbourne and Mt. 

 Macedon ; in December and March. 



It is possible that G. argyroneurus Zi. (described from a single 

 South Australian specimen) may denote a variety of this insect, 

 as it possesses many of its characteristics ; but Zeller describes 

 the head as yellowish, the first and second branches of the median 

 vein as not reaching hindmargin, the second and third as becom- 

 ing confluent beyond the middle, and makes no mention of any 

 white sub-apical spot. Considering the close affinity of the spe- 

 cies of this group, it would be premature to adopt the name for 

 this insect.
