three mostly pale brownish, the tubercles of other segments of 

 the sam>e color; spiracles circular, pale brownish. 



Pupation takes place in a tough cocoon in a tunnel in which 

 the caterpillar has lived, it being either near the outside, or else 

 has one end near the outside so that the moth may readily emerge. 

 The empty pupa cases may be seen projecting from these after 

 moths have emerged. The pupa (Plate II, Fig. 12) is about 10 

 mm. long; quite similar to that of imniiscula except that it is 

 larger and has two conical teeth wide apart ventrally on cremaster 

 instead of four close together as in uiiisciila; and the frontal 

 protuberance is more prominent, in lateral view the ventral point 

 is about a right angle, and there is but one carina extending 

 dorsally. 



Ercunctis pilosata n. s|). 



Male, 9 mm. Antennae whitish-ochreous irregularly marked above with 

 dark fuscous, basal segment dark fuscous, with pecten below. Palpi 

 cinereous-fuscous. Head and thorax cinereous-fuscous. Forewings irre- 

 gularly mixed with white and fuscous, and a sprinkling of black scales, a 

 few pale brownish scales along dorsum and a spot at apex; cilia cinereous 

 fuscous : apex upturned. Hindwings pale ochreous ; cell on upper surface 

 clothed with pale ochreous elongate scales ; space between cell and costa 

 clothed with long yellowish hairs ; an oval transparent spot at base below 

 lower margin of cell ; cilia pale cinereous-ochreous, a few dark fuscous 

 scales at apex. Abdomen fuscous mixed with ochreous, especially on the 

 seginental margins. Legs fuscous, hind tarsi marked with whitish. 



Two males, British New Guinea (Muir). The larva feeds in 

 cane similarly to what E. Hm'isfriafa does in Hawaii. 



ErciDiefis iiiuiriella n. sp. 



Female ; 10 mm. Antennae whitish-ochreous faintly marked with 

 fuscous. Palpi ochreous. Head pale grey. Thorax greyish-ochreous with 

 a black spot posteriorly. Abdomen shining greyish-white. Forewings pale 

 ochreous grej^; a narrow black line on basalthird of costa; a small black 

 spot beneath costa near base ; a black dot about the middle of fold ; a 

 tiny black dot in cell; four tiny black dots beneath outer half of costa; 

 apical portion of wing with several suffused dark fuscous spots, cilia grey, 

 spotted with dark fuscous around apex. Hind wings and cilia pale shining 

 grey, a few fuscous scales at apex ; oval transparent area below cell at 

 base. Legs grey, tarsi fuscous-marked. 



One female. British New Guinea (Muir). The larva feeds in 

 cane similarlv to what E. flavistriata does in Hawaii.
