MACROGLOSSUM. 387 



than in other species ; costal edge of hind wing dilated into 

 a lobe before middle. Expanse : ^2 49-54 mm. 



<£. Tenth tergite gradually narrowed, apex obtuse, slightly 

 curved downwards ; sternite rounded at end. Clasper with 

 friction-scales ; harpe (fig. 91 H) short, stout, upperside 

 excavated and edges dentate, looking like a tooth-brush in 

 a side-view. Process of penis-sheath (fig. 91 I) slender, 

 denticulate at proximal edge and at the rather obtuse tip, 

 a large patch of teeth at and near its base on the sheath. 



Hab. E. Himalayas to the Philippines. Rather rare, and 

 early stages unknown.

Imago. — <£$. Close to corythus luteata in colour. Three 

 small pale yellow side-spots on abdomen, the first reduced 

 to a transverse line, the second smaller than the dark brown 

 patch at its basal side, the third again more or less linear. 

 Underside of abdomen with the seventh segment grey, proximal 

 segments with grey mesial patches ; side-tufts tipped with 

 white, last two often somewhat ochraceous. Yellow area of 

 hind wing reduced, not extending so close to distal margin 

 as in most specimens of corythus, more sharply .defined 

 distally. Expanse : $ 60 mm., $ 66 mm. 



$. Harpe very short, hooked at end, obtuse, apical part 

 denticulate. Process of penis-sheath (fig. 91 J) shorter than 

 in corythus, obtuse, dentate at proximal and distal edges ; 

 teeth on sheath at base of process very numerous, extending 

 far proximad, sometimes arranged in two long rows ; rods 

 within sheath both obtuse. 



Hab. E. Himalayas and Ceylon to Formosa. Rather rare, 

 and early stages unknown.
