Legs very pale cinereous ; hind tibiee very pale cinereous, shaded

Type, S $ Bactylota Jtinkerella, Snell. 



The name Bactylota, given by Snellen to this genus, being pre- 

 occupied by Brandt in the Echinoderraata (1835), I have thought 

 it desirable to change it to Bidactylota, a name which if read in a 

 certain sense is sufficient to indicate its origin, but which equally 

 applies to the structure of the genus.

Antennae jtale fawn. 

 Palpi very pale fawn. 

 Head and thorax rich fawn-brown. 



Fore ivings rich fawn-browu to very near the middle, beyond 

 fuscous speckled with pale cinereous ; the margin of the two coloiirs 

 is straight and distinct across the wing, but with no dividing-line ; 

 cilia pale cinereous, with a line of fuscous scales along their middle. 

 Hind wings pale greyish fuscous ; cilia long, purplish grey. 

 Abdomen fuscous, pale cinereous beneath ; the protruding anal 

 claspers white. 



Legs pale cinereous, with long greyish hairs on the hind tibiae 

 above, projecting over the spurs ; hind tarsal joints barred with 

 fuscous.

This is the third species of the genus now known. The hind 

 wings distinctly divided to one fourth into two separate lobes, seems 

 to justify its position. In a single specimen I am unable to examine 

 critically the neuration, but it appears to be in all respects similar to 

 Jiinkerella ; the wings, however, cwing to their very long and closely 

 packed cilia, have a squarer appearance, which makes them look 

 wider in proportion to their length ; this, however, is not the case 

 when the shape of the wing itself is examined. In this and the 

 American species (snellenella, Wlsm.) the second lobe of the hind 

 wings is somewhat more decidedly developed than in the European 

 type.
