587. Macroglossum mediovitta si)ec. nov. (PI. IV. f. in, S). 



fT. Differs from heliopJiila in the following points : Forewing more elongate, 



distal margin less convex, proximal edge of antemedian band not distinct, the basal 

 area being darker than in heliophila ; pinkish white median band very prominent, 

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

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

 scarcely visible, the disc ontside the white band being so deep brown tiiat the line 

 is obscured, the blackish brown area gradually shading off distally ; no sharjily 

 defined postmcdian costal grey space, R^ not grey, subapical spot .SO'' — R' small, grey 



postdiscal line vestigial. Hindwing : distal border evenly convex, narrower than in 



hrliopliila. Structure of genital armature of d as in hi'liophila.

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



?. Avery dark-coloured species. Abdomen with two prominent white basal 

 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

Wings, tippersidc. — Forewing : a wliitc or grey, narrow, straight, median band 

 as in .1/. kirioulo hirundo, the olive-black band at its proximal side dilated basail 

 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' aud 

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

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

 which is interrupted between H' aud R', area outside this band slightly greyish like 



the postmedian costal space and the basal area. Hindwing : distal iiorder 



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, sharply defined. 



Length of forewing : ? , 23 to L*5 mm.
