I HAVE again to thank Mr. G. V. Hudson for a further contribution of 

 interesting material. It is evident that there must be a large number of 

 species still awaiting discovery, and New Zealand entomologists should 

 lose no time in searching them out. Many are obscure and easily overlooked 

 from their resemblance to others ; some are probably very retired in habit ; 

 and some also are doubtless now rare, and verging on extinction. There 

 must also be large areas of promising ground where no entomologist has 

 yet set foot, especially on the west coast of the South Island and towards 

 the northern extremity of the North Island. 



Caradrinidae. 

 Aletia fibriata n. sp. 



<S. 44-46 mm. Head and thorax whitish-fuscous mixed with fuscous 

 hairs. Antennae brownish- ochreous, bipectinated almost to apex, pectina- 

 tions a 3, 6 4. Forewings elongate-triangular, costa almost straight, apex 

 obtuse, termen obliquely bowed, somewhat waved ; light fuscous, irregularly 

 strewn with whitish-ochreous and brownish or fuscous scales ; costa some- 

 what marked with fuscous and dark fuscous ; first and second lines very 

 fine, dentate, formed of fuscous and dark-fuscous irroration, first very 

 indistinct, second fairly distinct, dentations sometimes tipped with pale 

 dots ; orbicular and reniform somewhat paler, partially edged with dark- 

 fuscous irroration, which sometimes forms a spot between them, orbicular 

 oval, reniform narrow-transverse, somewhat oblique ; claviform obsoletely 

 indicated ; a terminal series of indistinct dark-fuscous dots : cilia pale 

 fuscous, tips whitish. Hindwings light fuscous ; cilia whitish-fuscous. 



Mount Richmond, 4,500 ft., in December (F. G. Gibbs) ; two specimens. 

 An inconspicuous species, but apparently quite distinct. 



Hydriomenidae. 



Phrissogonus laticostatus Walk. 



Larentia laticostatus Walk., 1196 ; Scotosia canata, ib., 1357 ; Phrisso-

 posterior edge more or less marked with black, upper | rather strongly 

 curved and forming two slight angles, indented on fold, on upper half 

 partially preceded by ochreous-brown suffusion : cilia whitish obscurely 

 barred with grey. Hindwings with termen rounded, in (^ grey- whitish, 

 in $ pale whitish-grey, marked towards dorsum with numerous short grey 

 lines ; in rj a large patch of black irroration extending along costa from ^
