SCAEOSOPHIDAE 
The male genitalia of the genus Bathybalia which are described at some 
length below show a surprising resemblance with a type found in the 
family Cosmopterigidae. This similarity is so close, that we are compelled 
to regard the Scaeosophidae as nearly related to the Cosmopterigidae, in 
spite of the peculiar neuration of the hind wing in the former family. 
There are no clear indications, in fact, of a relation of the Scaeosophidae 
with the Oecophoridae, as surmised by several authors. We agree, there- 
fore, with Meyrick., who separated them from the Oecophoridae.

Head with closely appressed scales, side tufts spreading. Ocellus 
posterior. Proboscis developed, smoothly scaled. Antenna ^ / o , minutely 
ciliated in the male, scape elongate, clavate, with a pecten. Labial palpus 
long, recurved, rather thickened with smoothly appressed scales through- 
out, terminal segment 1, as thick as the median, acute. Maxillary palpus 
very small, appressed to the proboscis, scaled. Thorax smooth. Anterior 
tibia short, thickened with scales roughish below, tarsus short but longer 
than the tibia. Posterior tibia with appressed scales, slightly roughish at 
the apex above. Fore wing elongate, broadest at 1 / 3 , costa impressed in 
the middle, apex bluntly pointed; with large tufts of raised scales, lb very 
long-furcate ( 1 / 2 ), lower branch of the furca weak, 2 from beyond 3 / 4 ,
