smooth appressed scales, terminal joint distinct. Abdomen of 

 male with, very large tufted anal valves. Forewings broad, 

 unevenly dilated, costa in male simple, arched near base, in 

 female more or less concave beyond middle, apex in male obtuse, 

 in female produced, hindmargin hardly oblique, rounded beneath. 

 Hindwings rounded-trapezoidal, hardly broader than fore wings, 

 costa convex, apex in female very bluntly rounded. Forewings 

 with veins 7 and 8 stalked, vein 7 running to hindmargin. Hind- 

 wings with veins 3 and 4 rising from a point, 5 approximated to 

 4 at base, 6 and 7 stalked. 



Allied to Dicliclia ; differing by the short smoothly-scaled palpi, 

 and especially by the large tufted abdominal valves of the male, 

 and the peculiar distorted form of the wings in the female. In 

 form and in the difference between the sexes, the species approach 

 Cacwcia, between which genus and Dichelia they are in some sense 

 intermediate. The venation of the genus is however identical 

 with that of Diclielia. 



The sexes of the two species may be distinguished as follows : 



A. Forewings nearly rectangular at apex. 



1 . Forewings suffused with dark fuscous 



towards base . . . . . . 1 . simana, male. 



2. Forewings not suffused . . . . 2. similana, male. 



B. Apex of forewings produced. 



1. Hindwings grey .. .. .. 1. simana, female. 



2. Hindwings posteriorly yellow . . 2. similana, female. 



1. Anis. simana, n. sp. 



$ 7V', $ 8V'. Head, antenna), and thorax whitish-grey; 

 palpi pale greyish-fuscous, apex darker. Abdomen pale ochreous 

 grey. Legs ochreous-whitish, anterior and middle tibise and 

 tarsi banded with dark fuscous above. Forewings broad, oblong ; 

 in male costa strongly arched towards base, apex nearly 

 rectangular, hindmargin perpendicular ; in female costa very 

 strongly arched near base, posteriorly sinuate, apex strongly
