154 NOVITATKS ZOOLOGICAE XXII], 1916. 



beyond this, on forewiag close to it, though receding somewhat posteriori}-, on 

 hindwing strongly excurved beyond the cell-dot. 



Underside with almost black, usually thick, postmedian line, its position almost 

 corresponding with that of the vein-dots of upperside. 



French Guiana: Nonvean Chantier, November (type c?), December (1 ?); 

 St. Jean de Maroni, November (2 ? ? ). Type in coll. L. B. Prout. 



Antenna of $ dentate, with the cilia a little longer than diameter of shaft ; 

 hindtibia of $ with hair-pencil : hindwing of $ with a tuft of hair on abdominal 

 margin opposite an orifice and flap on the pleura of the third abdominal somite. 

 Possibly a separate species ; of subrufa subrufa I know only Warren's two originals, 

 both ? , but the shape and the characteristic venation (see Gen. Ins. fasc. 104, p. 83), 

 as well as the subapical markings and other points of agreement, induce me to unite 

 the two forms. 



7. Achlora doris sp. nov. 



S ? , 30-32 mm. Exceedingly like cuprinaria Guen., and zoii Prout, but 

 considerably smaller. Structure of the latter, but with the antennal pectinations 

 little longer than in the former (in cuprinaria about three to three-and-a-half times 

 diameter of shaft, in doris about four times, in zoe six to seven times). Differs 

 from both in that the gronnd-colour is more rufous (less purple), especially in the 

 distal area, and that the postmedian line of the forewing is more strongly curved 

 about the radials, being oblique inwards at the costal end, not (as in all the other 

 known species) about vertical to the costa. 



Brazil: Para (Stuart), type <3 and two others (c? and ?) in coll. Tring Mus., 

 one dated November 17, 1892. A c? from British Guiana, July 17, 1902 (C. B. 

 Roberts) in coll. Brit. Mus. 



8. Achlora euctenachlora sp. nov. 



c?, 43 mm. Akin to inju?ictaria Hb., and belonging to the same structure- 

 group — hindwing with R 3 -M' separate and without hair-tuft beneath. Larger, 

 the antennal pectinations considerably longer, about ten times diameter of shaft, 

 and reaching more nearly to the apex (extreme tip lost). Ground-colour slightly 

 more reddish, with the postmedian and subterminal lines rather more deeply dentate, 

 the latter (especially on the under-surface) more sharply expressed. Termen of 

 hindwing rather markedly straightened from apex to R 3 (almost as in coenobiatct 

 Feld.). 



"Brazil" (probably Amazon region). Type in coll. Tring Mus., ex coll. 

 Felder. 



I feel no doubt this is the specimen on which Warren founded his genus (sub- 

 genus) Euctenachlora, for Felder's unique type of coenobiata has lost the antennae 

 (except the extreme stumps, which have not sufficiently long pectinations) and 

 possesses the hair-tuft on hindwing beneath ; but if his statement that the antenna 

 is bipectinate to apex was founded on accurate observation, a slight breakage must 

 have subsequently occurred. No other specimen extant in the Tring Museum would 

 have met the requirements. 



9. Macrotes commatica sp. nov. 



6, 66-74 mm. Closely allied to netrix Cram., but larger, the S antenna 

 without the specialised hairs on the distal third.
