whether it may uot be identical with one of Lord Walsingham's 

 genera ; 1 can only affirm that it has structures which are not 

 mentioned as characteristic of any of his genera. 



Titanomis, n. g. 



Head shortly rough-haired on crown (face denuded) ; ocelli 

 present ; tongue well-developed. Antenna? with joints closely 

 set (partly broken). Labial palpi (in female) moderate, 

 obliquely ascending, second joint shortly rough-scaled beneath, 

 terminal joint short, stout, obtuse. Maxillary palpi moderately 

 long, folded. Thorax with a slight double posterior crest, 

 beneath densely short-haired. Forewings with vein 1 strongly 

 furcate, 2 from near angle, 3 and 4 stalked, 7 to hindmargin, 

 11 from middle, secondary cell well-defined. Hindwings broader 

 than forewings, oblong-ovate, cilia ^ ; towards inner margin 

 wholly clothed with very dense long hairs ; veins tolerably 

 parallel, forked parting-vein well-defined. 



Tit. sisyrota, n. sp. 



Female. — 65 mm. Head, palpi, and thorax whitish suffusedly 

 irrorated with dark fuscous (partly defaced). Antennae fuscous. 

 Abdomen rather dark fuscous. Anterior legs dark fuscous, apex 

 of joints obscurely whitish (middle and posterior pair broken). 

 Forewings elongate-oblong, costa gently arched, apex rounded, 

 hindmargin rather oblique, slightly rounded ; rather dark 

 fuscous, irrorated with white except on an irregular posteriorly 

 dilated median longitudinal space ceasing before hindmargin, 

 and somewhat sprinkled with black on veins ; a black streak 

 along submedian fold from near base to beyond middle, inter- 

 rupted before its apex by a subtriangular white spot : a black 

 longitudinal streak in disc from before middle to about ^, inter- 

 rupted by a small round white spot at f : cilia rather dark fus- 

 cous, barred with white (imperfect). Hindwings and cilia fuscous. 



Wellington, in May ; described from a specimen in poor con- 

 dition, taken by Mr. (1. V. Hudson, who lias since obtained a 

 second. It is much the largest Tineid of New Zealand. The 

 larva is probably a wood-feeder. The discovery of the male is 

 very desirable. 



HYPONOMEUTIDJ-:. 



Head with appressed scales ; tongue developed. Forewings 

 with vein 1 furcate, 11 from before middle of cell. Hindwings 

 with veins 3 and 4 separate. 



The following genus is most allied to the South Pacific 

 Cyaihauia. 



Lysiphraoma, n. g. 



Head with loosely oppressed scales, side- 1 lilts more or less 

 rough ; ocelli present ; tongue short. Antenna 1 f, in male with
