 terior half partly, and posterior half wholly, suffused with brown ; six 

 sectors, the 4th and 5th connected, the 6th connected with cubitus ; ten 

 gradate veinlets in inner series, thirteen in outer, each series marked by a 

 dark- brown line angulated near costa ; a dark»brown spot on upper branch 

 of superior cubitus before 1st gradate series ; termen not very deeply ex- 

 cised, with two white marginal spaces. Hindwings iridescent ; costa 

 brownish-fuscous, darker on pterostigma ; outer gradate series and an 

 irregular dorsal spot fuscous. Legs pale brownish -ochreous. 



Length of body, 6 mm. Expanse of wings, 16 mm.

The nearest relation of this species appears to be the Australian D. 

 hinoculus, McL. 



Drepanepteryx humilior, n. sp. 



Light brownish-fuscous. Antennte ochreous, ringed with brown. Fore- 

 wings with apical margin only slightly excised ; subhyaline, faintly clouded 

 with greyish - brown ; nine gradate veinlets in inner, thirteen in outer, 

 series ; veins marked with brown ; numerous brown spots irregularly dis- 

 tributed, with a large brown spot on upper branch of superior cubitus before 

 1st gradate series. Hindwings hyaline, iridescent ; subcosta shaded with 

 fuscous, paler on pterostigma ; a fuscous line along outer gradate series, 

 and a light - fuscous dorsal suffusion. Legs pale ochreous. Abdomen 

 ochreous beneath. 



Length of body, 5 mm. Expanse of wings, 13 mm. 



Hab. — Wainuiomata River, Wellington. 



Quite distinct from the Queensland D. humilis, McL., which, in all 

 probability, has never occurred in New Zealand, and should therefore be 

 excluded from New Zealand lists. 



TRICHOPTERA. 



Genus Helicopsyche, Hagen. 

 Helicopsyche zealandica, Hudson, n. sp.

 pubescence ; 1st joint with longish hairs. Maxillary palpi stout, terminal 

 joint curved, ascending ; densely hairy. Wings with dense clothing of

 minal pair ; tarsal joints pale-tipped.

The species is structurally described here for the first time, I have 

 adopted the name suggested by Mr. Hudson.
