Genera and Species o^Pyralidse. 133 



Idiostrophe, gen. nov. 



Closely related to Omiodes, but distinguished by the palpi 

 and the male antennas; the palpi are thick and upcurved in 

 front of face, with the third joint bluntly conical and well 

 separated at its base from the second. The male antenna? 

 are fine, filiform, with a thickened angulation near base, 

 above which the shaft is curved and twisted ; the patagia of 

 the male are produced as in Omiodes. 



Type Idiostrophe albipunctata, sp. n. 



Idiostrophe albipunctata, sp. n. 



Fore wings fuscous, with the lines darker ; first line curved, 

 thick, from one fourth of costa to one third of inner margin, 

 followed below the median vein by a small pale spot ; in the 

 cell are two indistinct dark fuscous spots, separated by a round 

 hyaline spot ; underneath this spot, below the first median, is 

 a similar hyaline spot, dark-edged at either end ; second line 

 thick, dark, vertical in its upper and lower thirds, forming a 

 rectangular sinus outwards in the middle ; it is edged with 

 dull whitish in lower third, with three white dots between 

 the veins opposite the sinus, and with two dots only above, 

 the costal space being without white dots. Hind wings with 

 a thick blackish discal blotch, with paler on each side; second 

 line as in fore wings, the white edgings broader and plainer, 

 the lower of the two white spots above the sinus large. 

 Underside paler, with the markings clearer. 



Expanse of wings 32 millim. 



One male from Mackay. 



Genus Coptobasis, Led. 

 Coptobasis? subamescens, sp. n. 



Wings wholly dull bronzy fuscous, with the lines and 

 stigmata all a little darker, but very indistinct, the ground- 

 colour beyond each being just a trifle paler; two stigmata in 

 the cell ; the exterior line thick at two thirds, curved inwards 

 along the first median ; fringes concolorous. Hind wings 

 like fore wings. Head, thorax, and abdomen all dark dusky 

 fuscous. Underside glossy, bronzy. 



Expanse of wings 32 millim. 



Two females from Queensland. 



Probably a Coptobasis, but the position must remain 

 doubtful in the absence of the male.
