Meyrick. — Descriptions of New Zealand Lepidoptera. 109 



base dotted with dark-fuscous irroration. Hindwings light grey, darker 

 posteriorly ; cilia grey-whitish, greyer towards base. 



Otira Eiver, in December (Hudson), and I have an example from Grey- 

 mouth. Allied to the preceding. 



Atomotricha Meyr. 



I propose to merge the genus Brachysara in this, the difference of the 

 palpi being slight ; all the species (I now add three more) are very similar, 

 and have more or less slightly developed scale-tufts on forewings ; the 

 variation in development of the wings of the $ is specific ; the palpi are 

 alike in the sexes. 



Atomotricha versuta n. sp. 



<$. 23-28 mm. Head and thorax pale brownish-ochreous, shoulders 

 or front of thorax sometimes dark fuscous. Palpi whitish-ochreous, with 

 second joint exceeding base of antennae, rather rough towards apex beneath, 

 suffused with dark -fuscous irroration on lower | and a subapical ring, ter- 

 minal joint rather more than half second, more or less sprinkled with dark 

 fuscous. Antennal joints thrice as long as their apical width, ciliations 5. 

 Abdomen whitish-ochreous. Forewings elongate, rather narrow, slightly 

 dilated posteriorly, costa gently arched, slightly sinuate in middle, apex 

 obtuse, termen very obliquely rounded ; light brownish-ochreous, with 

 scattered black and dark -fuscous scales, in one specimen suffused with 

 fuscous except on dorsal third ; stigmata represented by brownish or fuscous 

 rings, usually incomplete beneath, plical obliquely beyond first discal ; 

 sometimes a fine angulated fuscous line from f of costa to tornus ; in the 

 largest specimen there is a strong black median longitudinal streak from 

 base to §, thence attenuated to f : cilia whitish-ochreous mixed with fuscous, 

 with a basal series of blackish dots. Hindwings pale whitish-ochreous 

 more or less tinged or suffused with light grey ; cilia pale whitish-ochreous, 

 with several fuscous basal dots. 



$. 17-19 mm. Forewings broad - lanceolate, acuminate; ochreous- 

 brownish or fuscous, dorsal area sufi isedly paler or whitish-ochreous ; 

 fold more or less suffused with dark fuscous on basal third ; stigmata 

 represented by pale - ochreous spots edged about with dark fuscous or 

 blackish. Hindwings rudimentary. 



Karori, in August (Hudson) ; eight specimens (5 S, 3 $). 



Atomotricha ommatias Meyr. 



c? broader - winged than versuta, ground-colour always fuscous, stig- 

 mata not ochreous. $ with forewings not acuminate, hindwings partially 

 developed, ovate -lanceolate. Only from Christchurch, in August and 

 September, other records being erroneous, and founded on confusion with 

 allied species. 



Atomotricha isogama Meyr. 



Distinguished from all the others by the $ being fully winged, as large 

 as <$. This species and ommatias have long palpi.
