156 FAUNA HAWAIIENSIS 



curved-linear or reduced to two dots or wholly absent, sometimes edged with pale or 

 white posteriorly, often connected with second line by a blackish longitudinal suffusion ; 

 subterminal fine, whitish, interrupted, bisinuate ; all lines sometimes (but seldom) 

 wholly absent. Hindwings from rather light to rather dark grey. 



113 specimens; 12 Kona, Hawaii, at 1500 — 4000 feet; 11 Olaa, Hawaii, at 2000 

 feet ; 10 Hilo, Hawaii, at 2000 feet ; i Kilauea, Hawaii ; 6 Haleakala, Maui, at 5000 

 feet ; 20 Mts. Waimea, Kauai, at 4000 feet; 24 Kaholuamano, Kauai, at 4000 feet ; 18 

 Waianae Mts., Oahu, at 2000 feet; i Panoa Valley, Oahu ; i Kaala Mts., Oahu ; 8 

 Molokai, at 3000 feet ; i Lanai, 3000 feet ; from January to December, apparently 

 throughout the islands up to 5000 feet. Also about 20 specimens received from 

 Mr Blackburn, from Mauna Loa, Hawaii, and other localities. An excessively 

 variable species, differing not only in colour and intensity of marking, but the lines 

 themselves appear to vary greatly in form owing to the obsolescence of certain 

 portions and the confluence of others, the first and second lines sometimes appear- 

 ing almost straight ; the dark spots often look like tufts, but there are no real tufts 

 as in H. cyanias. The lighter specimens are usually $, the darker $, but this is 

 not always the case. H. croceipicta Hamps., from Ceylon, approaches it closely, 

 but seems distinct. The European H. costistrigalis Steph. seems constantly separ- 

 able by the whitish hindwings, otherwise it does not differ perceptibly from light- 

 coloured Hawaiian examples. The form exsularis Meyr., occurring in New Zealand 

 and Australia, has also whitish hindwings, and is therefore distinct from altivolans, but 

 perhaps identical with costistrigalis. 



Nesamiptis, gen. nov. 



Head loosely scaled, with frontal tuft. Antennae in ^ ciliated, with longer setae 

 at each joint. Palpi in ^ rather long, in % very long, porrected, second joint 

 thickened with rough projecting scales, terminal very short, almost concealed. Thorax 

 with appressed scales. Abdomen without crest. Tibiae with appressed scales. 

 Hindwings : 5 parallel to 4. 



Type N. plagiota. Differs from Hypena especially by the absence of any crest 

 on abdomen. 



First line strongly and evenly curved (2) ohsoleta. 



,, straight on lower half, obsolete above {i) plagiota. 



(i) Nesamiptis plagiota, sp. nov.
