Head, legs, pectus, and front of thorax above dark brown ; 
thorax grey, with a dusky median stripe, including a short 
black one in front; head behind the antenne, palpi, and 
abdomen yellow; palpi blackish on each side above. 
* Rossel Island, Oct. 18, 1888.” 
A single male. This insect may be the male of 7. Jamesi, 
Butl., described from a single female without further locality 
than New Guinea; but in this specimen the yellow is widely 
extended at the base of both pairs of wings above and less so 
below, and the outer half of the inner margin of the fore 
wings is blackish, instead of that of the hind wings. It is 
much to be regretted that insects of the genus Tenaris are 
often received singly, for it is impossible without large series 
from the same locality to be certain whether the numerous 
closely allied forms are really distinct or not, and we have 
therefore no alternative but to describe them provisionally as 
species. 
12. Tenaris affinis, sp. n. 
Exp. al. 93 millim. 
Male.—Extremely similar to the last species, but the base 
of the fore wings is slaty grey, extending from the base nearly 
to the end of the cell, conterminous with the dark costa, and 
then crossing the median nervure, and covering the whole of 
the wing between its lowest branch and the submedian, and 
likewise the hinder angle, leaving only the inner margin 
white, beneath the submedian nervure, which runs white 
through the dusky portion of the wing to its extremity; on 
the hind wings the costa and hind margin are moderately 
broadly blackish to below the upper branch of the median 
nervure ; the lower ocellus is larger and the outer rings on 
the underside are wider and darker. On the underside the 
yellow hair at the base is only visible between the median 
nervure and the inner margin, for the whole base of the fore 
wings and of the costa of the hind wings (for the costal 
edging is narrower between the base and the ocellus) is black. 
The thorax is darker grey than in 7. barbata, without 
black markings, and the palpi are black above. 
“ Rossel Island, Oct. 18, 1888.” 
If the single specimen had been a female J should certainly 
have regarded it as the female of the last. It has, however, 
more resemblance to 7. onesimus, Butl., in some respects.
