M. several iiiiii lii'dail. tlic secoiid lietweeii 1\I' ami SM'-', tlie two separateil nr ciiu- 

 tigiioiis ; two c'liuall} iiiclistiuct and ill-defiucd hands or traces of such on disc, the 

 external one more or k'ss dentate, widened at costal margin, here ineliiding a white 

 Innule (which stands really at the jiroximal side of the dentate line proper) ; the 

 marginal area partly or almost totally filled up with brown scaling, especially 



between U- and M-, this brown area absorbing more or less the dentate line. 



Hindwing : the tawny red speckles large, becoming blackish brown at the abdominal 

 margin, the two bands formed by the speckles broad, the external one not always 

 distinct. 



L'ndrrsidc : speckles of both wings large. Forewing : bands as above, but 



those in the basal half red : subapical white i)at( h larger than above, more s(|uare ; 



fringe black at ends of veins. Hindwing: discal band not touching lower angle 



of cell, about 2 mm. broad ; the others nearly parallel to margin, not concave beyond 

 middle ; costal margin more th.an twice as long as abdominal margin. 



<?. Abdomen open behind owing to the peculiar develoj)ment of tlie claspers. 

 Tenth tergite (PI. XL. f. 11, ventral view) broad, sinuate, lobes rounded ; sternite 

 broad, strongly narrowed to apex, which is truncate, middle of sternite sunken. 

 Clasper (PI. XL. f. 8): dorsal margin produced disfally into a long process which 

 is armed with thin acute teeth ; ventral part of clasper reduced, rounded, densely 

 clothed with small scales ; a snbbasal rather slight fold, and another fold situated 

 more distally beset with bristles ; harpe represented by a long pointed process ; the 

 processes of the two harpes close together. Penis-sheath (PI. XL. f. 14) short, 

 stout, curved, ending in a short jirocess which ajipears clubbed in side-view, but 

 is compressed and therefore pointed in dorsal view. 



?. Vaginal plate (PI. XVIL f. 2) larger than in the other species; viiginal 

 orifice (F) on a kind of postament which is compressed to a ridge at each side, 

 the ridge truncate with the angles projecting ; behind this elevated structure there 

 is a deep cavity the hinder (or upper) wall of which is formed by the largo, strongly 

 chitinised, jiostvaginal jilate (/"'/>), this jilate niesially carinate within tlie cavity, 

 and transversely rugate or folded distally. 



Iffifj. Congo basin and East Africa ; its range extends probably farther noith. 



In the Tring Museum 2 c?c?, 3 ? ? from the Congo: P>opoto, August and 

 Deeemher (<>ram : K. Smith) ; and Portuguese East Africa. 



!>•?. Platysphinx phyllis spec. nov. (PI. I. f. 1, ?). 



?. AVings comparatively shorter and liroader than in the other species ; body 

 and wings paler. 



Wings, iipperside, speckles sparser, on hindwing in size midway between 



those of constrigilis and stigmatica. Forewing : hinder angle less rounded ; 



subbasal line indicated by an obli(iue indistinct line in cell in front of base of M- : 

 a line in apex of cell, broader than in co)isfri(//l/s, much narrower than the respective 

 patch in st>(j/mat/ca, iormiug as iu the latter species an obtuse angle with W, a short 

 elongate cusL.il mark at base of fork indicating a discal line, another narrower mark 

 hallway to apex, a browu apical patch, sharply defined behind, within it a trace of 

 the white spot of the other species ; speckles somewhat denser in marginal area 



between IV and M- and along R^. Hindwing: abdominal margin ])aler than in 



the other sp(>cies, with few speckles : the inner discal band vestigial, nearly straight, 

 the second and third ]iresent in roitstrii/illM not marked.
