Fore wings with costa faintly concave in middle and 

 slightly convex before apex, which is blunt ; hind margin 

 evenly curved. Hind wings round, with well-rounded hind 

 margin. Antennai of male filiform ; the basal joint long and 

 swollen, subdentate at the top, the shaft thickened at its base 

 and apparently articulated to the basal joint; tongue and 

 ocelli present; labial palpi porrect, broad, flattened, terminal 

 joint blunt and scarcely protruding beyond the scales of the 

 second ; maxillary palpi slender, upcurved. Neuration 

 normal. 



Type Arthriobasis lactiguttalis, sp. n. 



There is no hollowing out of the shaft of the antennas above 

 the basal joint, as in Coptobasis. 



Arthriobasis lactiguttalis, sp. n. 



<$ . Wings greyish black, with the exterior line denoted on 

 the costa by a large milk-white blotch, the denticulations of 

 the same line below being more or less marked with white 

 scales ; in the cell are four small white spots, of which the 

 third is conspicuous ; the submedian fold is interruptedly 

 white, and a whitish spot on the inner margin marks the end 

 of the two transverse lines ; base of the fringes with round 

 white spots at end of the veins, the two above the anal angle 

 lengthened. Hind wings with the exterior line picked out 

 with white scales, forming three rounded teeth in the middle; 

 fringes as in fore wings. Head, face, thorax, and abdomen 

 blackish ; basal segments of the latter varied with whitish. 

 Underside much whiter; the cell of the fore wings white, 

 showing two ocelloid stigmata.
