fuscous. Abdomen grey-whitish. Legs ochreous-whitish; middle 

 tarsi annulated with fuscous; anterior pair mostly fuscous. Forewings 

 with basal ^ of costa folded on lower surface to form a pouch, in- 

 cluding a large tuft of scent-scales; costa bisinuate, apex acute, termen 

 sinuate, scarcely oblique; pale-green; a brownish-fuscous patch on 

 base of costa; a suffused, bisinuate, fuscous line from i costa to f 

 dorsum, preceded by some fuscous irroration above dorsum; an out- 

 wardly-oblique, oval, discal spot beneath mid-costa, brownish outlined 

 with fuscous, a short dark-fuscous longitudinal mark beneath this, 

 and a broad bar of brownish-fuscous suffusion extending to termen 

 immediately beneath apex; a finely dentate, fuscous line from f costa 

 to i dorsum, curved outwards in middle; an interrupted dark-fuscous 

 terminal line, enlarged to form elongate marks beneath apex; ci\ia 

 greenish, apices grey. Hindwings with termen sinuate; ochreous-grey- 

 whitish; cilia concolorous. 



Q., National Park (2500 to 3000 ft.), in December and January; two 

 specimens. 



Fam. CRAMBIDAE. 



Crambus ammoploceus, n. sp. 



" A spinner of sand." 



(^ 24-27 mm. Head ochreous-whitish. Palpi 2; pale-grey; basal 

 joint ochreous-whitish. Antennae grey, towards apex darker, towards 

 base whitish. Thorax pale-grey. Abdomen ochreous-grey. Legs whit- 

 ish grey. Forewings somewhat dilated posteriorly, costa straight, 

 slightly arched before apex, apex rounded-rectangular, termen slightly 

 bowed, scarcely oblique; whitish-grey more or less irrorated with 

 darker-grey; an ill-defined whitish streak on basal half of fold; some 

 fuscous terminal dots; cilia whitish with a pale-grey ante-median line. 

 Hindwings whitish-grey, cilia whitish. 



N.Q., Dunk Island; two specimens received from Mr. E. J. Ban- 

 field, who has also sent larval galleries and cocoons with pupae, which 

 unfortunately did not survive. From these and from information 

 received from Mr. Banfield, I gather that the larvae inhabit galleries 

 several inches in length in the sand under Casuarina trees. The gallery 

 is lined with grains in the sand fastened together with silk; the larva, 

 emerges from the gallery, seizes the end of a piece of casuarina stem 

 that lies on the surface, and, biting off a convenient length, backs 

 down to the bottom of the gallery, carrying the fragment with it. In 

 captivity the pupae are found in egg-shaped cocoons of sand and 

 silk. 



Gen. Notocrambus, nov. 



Frons flat. Tongue present. Labial palpi moderately long,, 

 broadly dilated with rough scales, not hairy; terminal joint moderate; 

 antennae short (about i); ciliations in <^ imperceptible. Thorax and 

 abdomen stoutly built; thorax hairy beneath. Posterior tibiae, with 

 two pairs of spurs. Forewings with 2 from f, 3 from before angle, 

 7 from upper angle, 8 and 9 stalked. Hindwings with 2 from |, 8„
