414 Mr. A. G. Butler on Heterocerous Lepidoptera 



Phibalapteryx, Stephens. 

 A genus very easily confounded with Hemerophila, 

 but differing in the simple, or almost simple, antennae 

 of the males, whereas in Hemerophila they are dis- 

 tinctly pectinated. 



112. Phibalapteryx edna, n. s. 



^ . Almost exactly agrees in pattern with the 

 " Tephrosia " disperdita of Walker from Sydney ; upper 

 surface shining greyish white or silver-grey ; black- 

 speckled ; primaries crossed by two or three ill-defined 

 and interrupted irregular oblique blackish lines ; the last 

 of these lines runs from the outer margin near apex to 

 about the middle of the inner margin, is widely bisinuated, 

 and its upper half forms a strongly-defined black stripe ; 

 external border slightly darker than the ground colour, 

 and traversed by an undulated white -edged submarginal 

 line ; secondaries striated with dark grey to the middle, 

 excepting upon the costal area, and traversed beyond the 

 middle by a slightly irregular slender black line, followed 

 by a dark grey line ; border and submarginal line as in 

 the primaries ; primaries below sordid shining grey, 

 black- speckled, with a black disco-cellular dot and slender 

 marginal line ; secondaries shining white, speckled with 

 black to the middle ; a slender dark grey marginal line. 

 Expanse of wings, 38 mm.

113. Phibalapteryx jacintha, n. s. 



Allied to P. perfectata of Sydney, which it resembles 

 in size and in its pearl-grey colouring and blackish mark- 

 ings ; the belt across the primaries is, however, very 

 oblique, its outer edge being obtusely and widely zigzag, 

 more like P. anguligera of New Zealand ; the double 

 discal line of secondaries is also more prominent, owing 

 to the indistinctness of the other lines on these wings ; 

 all the wings have a small black disco-cellular spot and 

 slender sinuated marginal line ; under surface shining 

 white, sparsely black-speckled, with black disco-cellular 

 spots and marginal line as above, also a discal series of 

 black dots on the veins ; primaries with a faint brownish
