m Louis B. Front on the 
concave, accompanied by dark marks along the veins; postmedian 
line obsolescent at costa, very oblique outwards from SC^ to R*, 
obsolescent distally to cell, very strongly concave from R^ to anal 
angle, dark-marked on R^, and 
Puente del Inca, type and two co-types (one dated 
January 14, 1904) in coll. L. B, Front, one $ in coll. A. F. 
Bayne; all collected by W. M. Bayne. 
Mr. A. F. Bayne is strongly of opinion that this species 
is distinct from T. mihmnbrcda. of the lower altitudes, and 
the structural differences favour this view. The great 
variability of Dognin’s species, however, has already been 
commented upon, and must not be lost sight of, and even 
the position of its lines sometimes shows an approach to 
T. subsc7'i2}ta ; so that possibly some systematists will 
prefer to regard the latter as a local, mountain race. On 
the other hand, it is just possible tliat there are tw'o oi 
three very closely allied species mixed up under S7(huinhrata.

(Plate XLVIII, fig. 26.) 
d. 20 mm. Face fuscous, lighter above. Palpus fuscous. Antenua 
much as in the preceding species, with rather thin, sessile fascicles 
of moderately long cilia. Legs light brown-grey, spotted with 
fuscous; fore- and midtibiae and tarsi fuscous anteriorly, the latter 
ringed Avith light brown-grey ; hindtibia much dilated. Body fuscous 
above, light brown-grey beneath. Wings somewhat tawny browm, 
the ground-colour being formed by a mixture of brown-grey, tawny 
and whitish scales, irrorated with dark fuscous (more sparsely on 
hindwing). Forewing with lines blackish fuscous ; a subbasal line 
from one-fourth costa, strongly outcurved in cell, weaker and 
more slightly outcurved in posterior half; antemedian from 
two-fifths costa to just beyond one-half inner margin, entangled 
on M and SM2, accompanied distally by a diffuse dark grey 
shade ; postmedian line reduced to a thick, oblique streak from 
two-thirds costa as far as R* ; subterminal commencing as a Avhite 
streak from costa, obliterated beyond R', where it meets a longi¬ 
tudinal white streak running to the end of postmedian ; an ill- 
defined taAvny blotch in median area distally to cell; some ill-defined 
dark markings in sub terminal region, the most distinct being a dark 
spot on each side of R^, like the “ twin spots ” of many Larentiids ; 
marginal line dark, thickened between the veins ; fringe intersected 
by a weak dark line. Hindwing with an indistinct dark antemedian, 
which traverses the extreme distal margin of cell, and is angled at
