312. Coes tiiptycha, n. sp. 



Minor, alis ant. flavis, basi, dimidio costse antico, fascia postica 

 recta, (interdum etiam altera angustiori antica,) inaculaque margin is 

 postici elongata saturate purpureo-fuscis ; post, saturatius fuscis. 



£ £. 15-18 mm. Head and palpi yellow, second joint with 

 lower § externally fuscousT Antennas whitisL-ochreous, annnlated 

 with dark fuscous. Thorax dark purple-fuscous, with a large 

 anterior yellow spot. Abdomen dark fuscous, segmental margins 

 yellowish. Legs fuscous, posterior pair ochreous-yellowish. 

 Forewings elongate, costa gently arched, apex round-pointed, 

 hindmargin almost straight, very oblique ; ochreous-yellow, mark- 

 ings dark purple-fuscous ; a streak along anterior half of costa, at 

 base extended to inner margin ; sometimes a narrow straight fascia 

 from middle of costa almost to middle of inner margin, but this is 

 generally quite absent ; a moderately broad straight fascia from | 

 of costa to anal angle, contracted above ; an elongate blotch along 

 upper half of hindmargin : cilia dark fuscous, beneath anal angle 

 yellowish. Hindwiugs and cilia dark fuscous. 



The variation of this species in the occasional presence of an 

 anterior fascia which is usually wholly absent is quite singulai', but 

 I have no doubt that the two forms really constitute a single 

 species ; the difference is not sexual. 



Helidon, Queensland; Sydney, New South Wales; Melbourne, 

 Victoria ; rather common in September, October, and January, 

 amongst Acacia decurrens.
