GEOMETBID NOTES. 79 



7. Semiothisa richardsi, mihi, sp. nov.* 



Male, 25 or 26 mm. Pale fawn-colour, with extremely faint indi- 

 cations of somewhat darker, more ochreous transverse lines or shades. 

 Fore wings with a pale outer hne at just beyond two-thirds, nearly 

 parallel to hind margin, but curving very slightly outwards at inner 

 marginal end. In the region of this line and bisected by it are some 

 blackish marks, namely: between veins 2-3, 3-4, 4-5 rather large 

 wedges, the one between veins 4-5 the smallest, that between 3-4 the 

 largest, further interrupted (as is also that between 2-3) near its outer 

 extremity by another very fine pale line ; between veins 5 and 8-9 

 smaller and more irregular dark spots, inclining to form a row of 

 three each longitudinally. Hind wings also with pale post-medial 

 line (which is here very indistinct), and with small irregular blackish 

 markings on either side of it between veins 2 and 4. Fringes con- 

 colorous, fuscous-spotted. Under side bright golden brown, vaguely 

 spotted with whitish, the whitish markings somewhat inclined to 

 dispose themselves in transverse lines. Margins of wings almost 

 even throughout, hind wings very slightly produced at vein 4. 



Female unknown. 



Tientsin ; one male, in my collection. 



In its ground colour and the general pose of the markings this 

 species reminds somewhat of the least strongly-marked examples 

 of Semiothisa oniataria, Leech (Ann. Mag. Nat. Hist. ser. 6, xix. 

 310) from Moupin, but besides the absence of the spot on costa 

 towards apex and other slight differences of arrangement the 

 shape of the wings and the scheme of the under side are quite 

 different, agreeing with those of Tephrina murinaria, Schiff., in 

 its brightest coloured forms. The antennal ciliations are normal 

 for Semiothisa. 



8. Stegania honesta, mihi, sp. nov. 



Sexes similar. 26 mm. Fore wings reddish buff or pale testa- 

 ceous, somewhat variable in different individuals, rather thickly but 

 smoothly scaled, glossy. Two indistinctly darker transverse lines 

 following practically the same course as in Stegania triviaculata, Vill., 

 and starting from dark costal spots (deep red-brown or blackish), as 

 in that species, but rather larger on the average. No third costal 

 spot. The second line accompanied distally by a narrow paler line, 

 which renders it more conspicuous. Outer margin very slightly 

 darkened. Fringes concolorous with wing internally, grey externally, 

 intersected with whitish at vein-ends. Hind wings much paler, 

 especially interiorly, and traversed by a single darker line (sometimes 

 very indistinct), following the same course as in S. triviaculata. 

 Under side almost without markings, or (in some individuals) with 

 the outer line of all wings more or less well expressed. Face deep 

 buff, vertex white. Antennae of male with rather long pectinations, 



^= Dedicated to my friend Mr. Percy Richards, to wliose kindness I am 

 indebted for this pretty little species, as well as for the one next to be 

 described.
