NoVITATES ZoOLOGtCAE XXV. 19I.S. 87 



straight, very faintly bicurved ; a very fine pale olive-bufif terminal line, accom- 

 panied proximally by slight olive-buff vein-dots and an indistinct darkened line 

 between them ; fringe paler in distal than in proximal half, with very slight 



pale dividing-line. Hindwing rather broad, termen strongly convex, bent 



in middle ; first line w anting ; ceU-dots small, black ; postmedian very slightly 

 (scarcely) curved ; termen and fringe as on forewmg. 



Underside more vinaceous ; both wings with small dark discal dot and 

 Ul-defined, rather thick, distally pale-margined postmedian line. 



Calama, Rio Madeira, below Rio Machados, August — October 1917 (W. 

 Hoffmanns). Type in coll. Tring Mu.seum. 



Lipotaxia gen. nov. 



Face smooth. Palpus rather short, second joint with appressed scales, third 

 joint short and slender. Antenna hi both sexes ciliated. Pectus hairy, o 

 hindtibia with strong hair-pencil, hindtarsus short ; $ hindtibia witii terminal 

 spurs only. Forewing with termen smooth, curved, oblique ; areole double, 

 SC" from ceU, R^ from middle of DC. Hindwiag with abdominal margin rather 

 long, termen convex, nearly smooth ; SC* not stalked. 



Tjrpe of the genus : Lipotaxia rubicunda (Warr.) = Lipomelia rubicunda 

 Warr., Novit.'^tes Zoologicae, xii. 324. 



Probably a direct development of Semaeopus, differing in the absence of 

 the median spurs on the ? huidleg. 



25. Lipotaxia (?) segmentata subvestita subsp. nov. 



o. Differs from name- typical segmentata Warr. (Novitates Zoologicae, 

 xiv. 220), from Peru — which, although the 9 is unknown, wUl almost certainly 

 have to be transferred to Lipotaxia, being manifestly a near relative of rubicunda 

 — in having the outer line of the hindwing close to the termen, the grey shade 

 beyond at its widest point considerably less than 1 mm. in breadth, and especiallj' 

 in having the hindwing beneath clothed nearly throughout with rough oehreous 

 hair-scales, a patch along the medians developed uito longish haii'. 



Fonte Boa, Upper Amazons, July 1906 (S. M. Klages). Type in coll. Tring 

 Museum. 



Should perhaps be regarded as a separate species. 



26. Dithecodes mys sp. nov. 



<J, 23 mm. Face red. Vertex and base of antenna white. Antenna with 

 minute ciliation. Occiput narrowly reddish. CoUar oehreous. Thorax and 

 abdomen grey above, whitish beneath. 



Forewing broad, termen smooth, oblique, slightly curved ; both areoles 

 rather narrow, SC" from stalk of SC'"" , R^ from appreciably before middle of DC ; 

 uniform mouse-grey with strong gloss, changing accordmg to the fall of the 

 light to slate-grey or almost pearl-grej' ; costal edge slightly darker ; fringe 

 paler. Hindwing with terinen rounded ; as forewing. cxcejit costal edge. 



Underside the same, or scarcely paler.
