42 FAUNA HAWAIIENSIS 



Two basal joints of antennae dark, the other joints infuscate, sHghtly paler at their 

 bases. 



Expanse i6 mm. 



Hab. Haleakala, Maui (5000 ft.); i % taken in Oct. 1896. 



(11) Nesomicromus longispinosus, sp. nov. 



Dark brown or blackish, antennae, including the two basal joints, testaceous, the 

 apices of the joints lightly infuscate. Legs testaceous, front and intermediate tibiae 

 largely fuscous. 



Anterior wings brownish-grey, nervuration for the most part dark, but interrupted 

 by pale spots, radius very distinctly alternately light and dark. At the extreme base of 

 the dorsal margin and about the cubitus towards its base, there is more or less dark 

 infuscation, and one or both of the series of gradate nervules are more or less infuscate, 

 and form dark lines. The wings are rounded at the apex, and the radius gives off 

 6 sectors. 



Posterior wings hyaline, nervuration pale, but darker along the outer series of 

 gradate nervules, so as to form an evident dark line. Radius connected with the sector 

 by several transverse nervules. 



Z appendices pale, narrow, the spines unusually strongly developed, and very finely 

 spinulose along one edge, very long, extending far behind the apices of the appendices, 

 and crossing one another. (Plate IV. fig. 15.) 



Expanse of ^ 13 mm.; $ 15 mm. 



Hab. Kilauea, Hawaii (4000 ft.) ; i t and i % taken. Remarkable for the long 

 spines of the Z appendices, and the additional transverse nervules in the posterior wings 

 of both sexes. 



(12) Nesomicromus haleakalae, sp. nov. 



Female closely allied to the preceding, rather larger and with the anterior wings 

 more grey, less tinged with brown. 



The black markings of the wings are more distinct, the dark markings along the 

 cubitus forming with the blackish suffusion along the gradate nervules of the inner 

 series a distinct curved blackish line. The radius gives off 5 sectors, and the elongate 

 cellules formed between the two series of gradate nervules, are evidently less narrow and 

 numerous than those of the preceding species. 



Posterior wings very much as in N. longispinosus, nearly hyaline, the radius and 

 sector connected by several transverse nervules.
