Fara. VII. Tineidse. 
Genus 32. Euplocamus, Latr. 
Euplocamus ursella. 
Tinea ursella, Walk, in Melliss’s St. Hel. 100 (1875). 
Expanse 11-13 lines. With the fore wings of a rich 
velvety mottled brown, and having a very glossy or silken 
appearance on the first emergence of the insect from the 
chrysalis, which, however, the mere fact of flight (more so, 
perhaps, in this particular group than in any other) tends 
greatly to destroy. Most frequently, indeed, it is captured of 
a palish brown hue, dappled more or less with very dark 
velvety brown, a dark blotch on the inner margin being then 
generally the most permanent marking, although sometimes it 
is altogether absent. Along the outer margin is a row of five 
or six remote yellowish spots, more or less apparent in dif¬ 
ferent specimens, being sometimes conspicuous and at others 
nearly absent. Hind wings of a pale glossy subhyaline 
whitish cinereous, gradually becoming more smoky towards 
the apex, and with the extremely long fringe of the same 
hue as the rest of the surface. Thorax concolorous with the 
anterior wings, body with the posterior ones. 
Var. /3 with the basal article of the antennaa thicker than 
in those of the type. Indeed I should have been inclined 
almost to have considered it even a distinct species, had not 
Prof. Zeller (who has kindly examined my specimen) pro¬ 
nounced it to be merely a variety of the present species. The 
fore wings are certainly of a more uniform brown (or less 
clouded with coarse black scales) throughout and more 
rounded at the apex; the fringe too of the posterior wings is 
appreciably darker. On measuring a series of the typical one 
(although varying greatly, which, indeed, is quite characteristic 
of this group), it does not in any instance exceed 15 lines, 
whereas the var. /3 is exactly 17 lines when expanded. Un¬ 
fortunately, however, I only met with a single example, the 
chrysalis of which, I believe, I secured from the interior of a 
rotten log of the u cabbage-tree ” wood. 
Var. 7 with the fore wings somewhat narrower and of a
