116. AdENA XANTHIALIS. 



Adena xanthialis, Walker, Lep. Het. xxvii. p. 168(1863). 

 Coll. J. D. Enys, Esq. 



This genus certainly has no business among the Cramhites ; it 

 should be placed among the Hypenida. 



TORTR ICITES. 

 TORTRICID^. 



117. TeRAS J5NEA, n. sp. 



Primaries with the central area brassy, gradually merging into 

 cupreous towards the borders, which are silky brown ; secondaries 

 brown, subcostal area yellowish, costal area pale stramineous ; body 

 above dark brown : wings below shining brassy yellow, the primaries 

 becoming greyish brown at the borders, the secondaries becoming 

 golden towards the outer margin ; body below creamy whitish. Ex- 

 panse of wings 1 inch. 



Mountain form. Coll. J. D. Enys, Esq. 



Found at 3000 to 4000 feet elevation. 



118. Teras flavescens, n. sp. 



Primaries straw-yellow, very indistinctly reticulated with deeper 

 lines of the same colour ; a spot at the extremity of the costal 

 nervure, a second less distinct at the end of the second subcostal 

 branch, and the apical half of the fringe, tawny ; secondaries white, 

 tinted with stramineous towards costa ; thorax ochraceous ; abdomen 

 (probably white) : primaries below whitish, with the basi-costal area 

 and apex ochraceous, crossed by orange reticulations ; apical fringe 

 tawny ; secondaries pale stramineous, reticulated with orange ; 

 pectus silvery white, legs ochraceous. Expanse of wings 1 inch 

 4 lines. 



South Island. Coll. Dr. Hector. 



This species seems to me to belong to the T. hoscana group. 



Several genera are confounded by Walker under Teras ; his T. ob- 

 longana and T. inaptana are probably also variations of one species ; 

 and I believe his T. servana, T. priscana, and T. contractana to be 

 synonymous ; but the specimens are in poor condition, which ren- 

 ders their accurate determination difficult. 



119. Cacoecia vilis, n. sp. (Plate XLIII. fig. 15.) 



Allied to C. herana of Felder. Primaries above shining sordid 

 testaceous ; subbasal area, base of inner margin, and external border 

 silvery grey ; a V-shaped basi-subcostal marking, an oblique bracket- 

 shaped line from the cell to the inner margin, and two or three dots 

 near the outer margin black -brown ; a semicircular costal brown 

 patch, a diffused brownish patch bounded within by the bracket- 

 shaped line ; secondaries white, the apical and abdominal areas 

 feebly tinted with testaceous ; head white, thorax brown : primaries 

 below reddish, markings indistinct ; secondaries sordid white, reticu-
