c? . 22 mm. Head whitish-fuscous, face ochreous-whitish. 

 Palpi light fuscous. Antennal ciliatious 1. Thorax light fuscous. 

 Abdomen light grey. Forewings elongate, moderate, costa gently 

 arched, apei obtuse, termen almost straight, vertical ; fuscous, 

 with slight purplish tinge ; three light greyish-ochreous lines 

 crossing wing, first at f, bent near costa, closely preceded by a 

 light greyish-ochreous fascia narrow on costa and gradually dilating 

 downwards, second and third bent above middle, third running to 

 tornus, a light greyish-ochreous patch extending along costa from 

 second to apex : cilia purplish-fuscous, tips grey-whitish on termen. 

 Hindwings grey ; cilia piile grey, faintly purplish-tinged.

APHANOXENA, n. g. 



Head with appressed scales, sidetufts roughly spreading ; ocelli 

 present ; tongue developed. Antennae f , in c? moderately ciliated, 

 basal joint moderate, without pecten. Labial palpi long, curved, 

 ascending, second joint thickened Avith appressed scales, terminal 

 joint somewhat shorter than second, stout, pointed. Maxillary 

 palpi very short, filiform, appressed to tongue. Anterior tibiae 

 very short, tarsi as long as tibiae, stout, scaled ; posterior tibiae 

 clothed with dense hairscales above. Forewings with 2 from angle, 

 sometimes faint and almost obsolete, 2-5 approximated towards 

 base, 6 to apex, 7 and 8 stalked for more than half length or 8 

 absent, 11 from middle. Hindwings much over 1, ovate, cilia ^ ; 

 3 and 4 short-stalked, 5 closely approximated at base, 6 and 7

 subcostal hairpencil above. 



Type 2iMocoma Meyr. This genus is obviously in every respect 

 closely allied to Antaeotricha, and cannot possibly be placed in a 

 different family, but the stalking of veins 7 and 8 breaks down the 

 distinction from the Xi/Joryctidae ; neither can one be maintained 

 on the position of vein 2, in which there is a complete ti-ansition 

 with numerous intergradations in various groups ; therefore after 

 consideration of the extensive material now available (including 

 such forms as Bolidiria, Falculina, and the hitherto problematical 

 Aeolanthes and Tludamarchis) I revert to my original view that 

 the group which I separated as the Stenomidae must now be merged
