<S ? . Differs from Mao-oglossnm in the end-segment of the antenna being short, 

 in K'-' of the hindwing arising from below centre of cell, and in W and M' being 

 stalked together. 



Earl}' stages not known. 



Hub. Africa. 



Two species. 



Erroneousl}' associated by Butler and otliers with the American Sesia taiitidas on 

 account of the white abdominal belt. The two insects are true }f'K:roglo.isun except 

 in the points mentioned above. The white belt is an e.^aggerated developmeut 

 of the grey side-spots found in Macroglo.^nitm xtellatarum, which species comes also 

 iu the shortness of the last antennal segment nearest to Ltucostrophas The pattern 

 of the forewiug, above, is as in Macroglos.snm. The hindwing is shorter than in 

 Macroglossutit, with the costal vein distinctly curved in front of the end of the cell, 

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

 also rather shorter.

6 ? . 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 niedio-basal and apici- 

 lateral bluish spot on the fifth tergite. 



6- Tenth tergite sinuate at end as in hirunilo (I'l. XLV. f. oj, long, slender 

 with long hairs; steruite also long, simple. C'lasper without friction-scales ; harpe 

 umall, curving upwards at end, dilated, edge of dilated jiart sliglitly denticulated, 

 Bnrface with setiferous warts (I'l. L. f 22). I'enis-sheatii as in Itiramki, rather more 

 strongly dentate.
