 black one in front ; head behind the antennae, palpi, and 

 abdomen yellow ; palpi blackish on each side above.

A single male. This insect may be the male of T. Jamesi, 

 Butl., described from a single female without further locality 

 than New Guinea ; but in tliis 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 tlie numerous 

 closely allied forms are really distinct or not, and we have 

 therefore no alternative but to describe them provisionally as 

 species.

Male. — Extremely similar to the last species, but the base 

 of the fore wings is slaty grey, extending from tlie base nearly 

 to the end of the cell, conterminous with the dark costa, and 

 then crossing the median nervure, and covering the wliole 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 tliorax is darker grey than in T. barbata, without 

 black markings, and the palpi are black above. 



" Rossel Island, Oct. 18, 1888." 



If the single specimen had been a female I should certainly 

 have regarded it as the female of tlie last. It has, however, 

 more resemblance to T. otiestmus, Butl., in some respects.
