below ; hind tibioe in % short, without spurs, with strong hair pencil, 

 and the whole tibia with a fringe of hair ; tarsi short. Wings even, 

 the hind wings below with a fringe of hairs bent backward at base 

 of vein 8, and a smaller fringe at vein la. 



I have the S only, and can give a diagnosis from it alone. 

 Species. — S.formosa Hulst, n. sp. 



S. ft>rniosa n. sp. — Expands 18 mm. Palpi ochreous, with a reddish tinge: 

 front dull reddish ochreous; thorax light violet lavender. Abdomen ochreous : 

 fore wings light violet lavender, with some scattered blackish scales ; fore wings 

 with costa dull red ; cross-lines broad, faint, yellow ocher, one intra-discal. a 

 second extra-discal, a third outer, and a fourth submarginal ; the outer line is 

 undulate with a rounding outward at cell and vein 2; the submarginal line runs 

 into the outer margin at vein 3 ; margin rather darker reddish : hind wings cor- 

 responding to fore wings, but third line becomes submarginal, and fourth line is 

 wanting, all very faint as in fore wings; beneath fore wings light reddish ochre- 

 ous, hind wings yellow ocher at base, light ocher outwardly.

12. CHAROMMAT^A n. gen. 

 Type ella Hulst. 



Palpi moderate, porrect, rather stout, long scaled below ; tongue 

 developed ; front close scaled, smooth ; antennae simple, fascicled 

 ciliate ; thorax and abdomen smooth ; hind tibiae of S swollen, 

 rather short, with pencil or fringe of long fine hairs clothing inner 

 side ; no spurs present ; upper tarsus swollen, lengthened ; also edged 

 with long fine hairs, end tarsi slightly developed ; hind tibiae in $ 

 with two pairs of spurs ; fore wings rounded, even, two accessory 

 cells, 12 veins, 6 separate from 7 ; hind wings rounded, with a slight 

 tendency to angulation at vein 4, 8 veins, 3 and 4 separate or at a 

 point. 



Easily known by the unique shape and pencilings of the hind legs 

 in % . The only species is very different in coloration from any of 

 our other species, and would scarcely be taken for a Sterrhid.

 reddish ; thorax bright golden-yellow. Abdomen fuscous yellow. Wings bright 

 clear yellow ; fore wings with faint, rather broad blackish basal line showing in 

 three or four spots; a faint extra-discal line, and an outer row of spots showing 

 between the veins ; this is followed by a submarginal band of spots, larger and 

 more strongly marked, the ones at anal angle and middle of the wings being 

 much larger and more distinct ; a marginal row of black dots between the veins; 

 discal spot large, round, distinct, blackish ; hind wings with the lines of the fore 

 wings continued, except basal line; beneath as above, but washed with purple
