15. Bathrotoma, n. g. 



Thorax smooth. Antennae in male ciliated, with an excavated 

 notch immediately above basal joint. Palpi moderate, porrected, 

 second joint rough-haired beneath and towards apex above, 

 terminal joint distinct. Posterior tibiae fringed with hairs above. 

 Forewings elongate, narrow, costa in male with a strong basal 

 fold, almost straight, hindmargin sinuate. Hindwings trapezoidal, 

 broader than forewings, posterior angle prominent, apex pro- 

 duced. Forewings with veins 7 and 8 separate, 7 running to 

 hindmargin, secondary cell distinct. Hindwings with veins 3 

 and 4 coincident, 5 approximated to 4 at base, 6 and 7 stalked. 



Belongs to the group of Strepsiceros ; distinguished from 

 Strepsiceros by the stalking of veins 6 and 7 of hindwings, and 

 the position of the notch immediately above basal joint of 

 antennae, from Tmetocera by the costal fold of male, from 

 Hendecasticha by the 12 veins of forewings ; the peculiarly shaped 

 prominent-angled hindwings are a special feature. 



Of the three species described below, only the first two belong 

 truly to this genus ; the third, B. scopulosana, is only kno\ n to 

 me in the female, and is placed provisionally in this genus, to 

 which it has an evident affinity, until the male is known ; but it 

 is discordant in the separation of veins 6 and 7 of hindwings, 

 and cannot remain here. 



The three species described may be thus separated : 



a. Forewings with a subquadrate dark blotch on 



inner margin at one-third. 



1 . Dorsal spot beyond middle erect, triangular 1 . constrictana. 



2. Dorsal spot beyond middle flattened, semi- 



oval . . . . . . . . . . . .3. scopulosana. 



b. Forewings without dark dorsal blotch ..2. ruficomana. 



1. Bathr. constrictana, n. sp. 



<$ $ . 5"-6J". Headochreous-brown on crown and face, behind 

 whitish finely irrorated with grey. Palpi deep ochreous-brown.
