S ? . Uitters from Macroylossmn in the ciid-segrueiit of the antenna being short, 

 ill 1{- of the hinilwing arising from below centre of cell, and in ii" and M' being 

 stalked together. 



Early stages not known. 



llab. Africa. 



Two species. 



Erroneonsly associated by Bntler and others with the American Scsia tantalus on 

 account of the wliite abdominal belt. The two insects are true M'u.-rot/lossum except 

 ill the points mentioned above. The white belt is an exaggerated development 

 of the grey side-sjiots found in Mncroylo-'isum Mellatarum, which species comes also 

 ill the shortness of the last antennal segment nearest to Leucostroplius The pattern 

 of the forewing, above, is as in Marroylossiim. The hiudwing is shorter than in 

 M'icrO(/lossum, with the costal vein distinctly curved in front of the end of the cell, 

 following the curve of the subcostal. The tarsi and the small (external) spurs are 

 also rather shorter.

S ? . The belt is bluish white and mesially excised in front. The bluish white 

 area of the fourth tergite does not (juite reach the apical margin ; it is of even 

 width, narrowing, however, a little laterally. There is a medio-basal and apici- 

 luteral bluish spot on the fifth tergite. 



S . Tenth tergite sinuate at end as in hivmuh (PI. XLV. f. .3), long, slender 

 with long hairs; sternite also long, simple. Clasper without friction-scales ; har])e 

 small, curving upwards at end, dilated, edge of dilated part slightly denticulated, 

 surface with setiferous warts (PI. L. f. "^2). Penis-slieath as in hinoulo, rather more 

 strongly dentate.
