c??. Second segment of palpus (PI. LIX. f. :.'ii) not narruwfr towards 

 base, Iciiig-er tliaii Iji'oad, but uot so louj;- as in iiiirij'i-rri, cavity of first segment 

 distiui-t. I'j.\tfriuil row of spines of first protarsal seg'tneut simple, or iloubled 

 only at base. Metanotum without black mesial dot : abdomen witliout oehrcous- 

 lawiiy lateral stripe, or (rarely) the stripe vestigial on the last segments. The four 

 discal lines of the forewiug above, of which two or three are generally strongly 

 dentate, foi'm at internal margin a conspicuous pulrli, which is often continued 

 costad, joining the i>ateh situated near stigma, this latter [>atcli not always marked. 

 Underside of both wings much mottled with brown scales, forming mostly short 

 transverse lines ; the brown border of the forewiug widened before 11', sometimes 

 almost extended to basal area. The clayish buff band on the u[)perside of the 

 hindwing always narrow ; it is best marked in the individuals which have the 

 distal part of the disc of the forewiug above buHish and the marginal border distinct, 

 while it is vestigial or absent from the more evenly coloured individuals. It 

 is peculiar that aarifcra, ucata, velula and monijoliaiia each have two forms ditfering 

 in the same way. 



S . The large scales of the clasper stand in pairs ; liarpe as iu acuta, rather 

 more curved. Penis-sheath (PI. JjVlII. I'. 20j isi/mmctrical, both processes with 

 several irregular rows of small teeth at the pro.ximal edge. Tenth sternite long, 

 sides jiarallel, ape.N obtusely rounded.

S ¥ . Second segment of palpus strongly narrowed towards base, triangular 

 (PI. LIX. f. 17), entirely different from the segment of celata, aurifcra, etc. ; 

 compare also the inner surface of the palpi of acuta, velata and aurijera 

 (PI. LIX. f. 1!). 2U. :il) ; cavity of first segment large. E.xternal row of spines of 

 the first protarsal segment doubled and trebled. In colour resemljling aarifcra, 

 the subdorsal tawny-ochreous stripe of the abdomen at least vestigial ; underside of 

 thora.K antl abdomen buff, less white than in aurifcra, the discal dots of the 

 forewing below smaller, the marginal area not joined to the basal one ; the 

 marginal area of the hindwing narrower, not so much dilated before W. There 

 are two foiTUs connected by intergradatinns, but the intermediate exam]des are 

 comparatively rare. In one form the ochreou.s-buff band of the hindwing is reduced, 

 being often just indicated near anal angle ; the forewiug has scarcely a yellow 

 tint, and the underside of both wings is dull clayish ochraceous with a tint of 

 brick-red. In the other form the forewing has here and there an ulive-yellow
