Lymantria aurora, Wlk. ( ?) 



I describe this species by the name by which it is known 

 in Australian collections, but have not been able to discover 

 Walker's description. It is not contained in the British 

 Museum catalogue. 



Male, 52 mm. Head whitish ; posterior margin narrowly 

 red. Palpi dark fuscous; aipex whitish. Antennae black, 

 pectinations whitish. Thorax whitish. Abdomen bright 

 red; a whitish basal spot; a series of four median blackish 

 spots on apical segments; tuft ochreous. Legs v/hit:sh, mixed 

 with red, tarsi annulated" with black. Forewings triangular, 

 co'sta moderately arched, apex round-pointed, termen slightly 

 rounded, oblique; grey- whitish, markings dark fuscous; ex- 

 treme base of costal edge red ; a spot on base of costa, and 

 another on mid-base ; a spot beneath costa at one-eighth, and 

 another beneath it on fold ; a thick wavy line from one-fourth 

 costa to two-fifths dorsum ; a small median discal dot ; a thick 

 wavy sigmoid line from costa just beyond middle to dorsum at 

 two-thirds ; a fine acutely dentate line from costa at three- 

 fourths to before tornus, partly confl.uent with previous line 

 near dorsum ; a row of terminal dots ; cilia grey-whitish. Hind- 

 wings with termen rouiided; ochreous-whitish suffused with 

 pale red, especially towards costa and inner margin ; cilia 

 whitish, at apex and inner margin ochreous-reddish. 



Female with wings aborted ; whitish ; forewing crossed by 

 two interrupted dark fuscous lines beyond middle. Head and 

 thorax whitish. Antennae whitish, pectinations black. Abdo- 

 men very large; pale ochreous-brown. 



Closely allied to' L. antennata, Wlk., which has fuscous hind- 

 wings, and the markings of forewings more suffused. 



Townsville, Queensland, in June; a pair received from 

 Mr. F. P. Dodd, who says the larvae feed on Eucalyptus tessel- 

 laris and other trees, and to pujpate suspend themselves among 

 a few golden-colored thread^ under leaves or between loose 

 strips of bark. 



Laelia ostracina, n. sp. 



Female, 36 mm. Head, palpi, and thorax whitish. An- 

 tennae broken. Abdomen ochreous-whitish. Legs whitish.
