587. Macroglossum mediovitta si)pc. nov. (PL IV. f. Id, c?). 



c?. Differs from hcUojjIiila in the following points : Forewing more eloigate, 



distal margin less convex, pro.ximal edge of autemedian band not distinct, the basal 

 area being darker than in keliopkila ; j)inkish white median band very prominent, 

 more obliqne, sharply defined, the first discal line being well marked, forming the 

 discal border of the white band, the line not elbowed anteriorly, second discal line 

 scarcely visible, the disc ontside the wliite band being so deep brown that the line 

 is obscured, the blackish brown area gradnally shading off distally ; no sharply 

 defined postmedian costal grey space, 11' not grey, subapical spotSC' — R' small, grey 



j)Ostdiscal line vestigial. Hindwing : distal border evenly convex, narrower than in

588. Macroglossum albigutta spec. nov. (PI. III. f. 3, ?).

 spots on seventh tergite, side-tufts of sixth and seventh segments brownish black 

 or burnt-umber-brown ; seventh sternite with white mesial dot or line. Underside

 line above eye distinct. 



Wings, upperside. — Forewing : a white or grey, narrow, straight, median band 

 as in M. Inrando Iiirundo, the olive-black band at its proximal side dilated ba^ad 

 at hinder margin, not sharply defined proximally ; the discal band at the distal side 

 of the median white band broad, ill-defined distally, dilated distad between R' and 

 R^, thus joined to a rather broad postdiscal band which extends from the two 

 subapical patches SM^ — R' to hinder margin, bordered proximally by a grey line 

 which is interrniited between R' and R^, area outside this band slightly greyish like 



the postmedian costal sjiace and the basal area. Hindwing: distal border 



convex, broader than yellow band, this interrupted or entire. 



Wings below dark mummy-brown, or Mars-brown, with the distal borders 

 darker, lines quite indistinct, third the best marked ; abdominal area of hindwing 

 yellow, sharjily defined.
