Underside as in celerio, but washed with green, and the ground-colour only 

 very slightly reddish on forewing and without a red tint on hindwing. 



Length of forewing : 28 mm. 



Hab. Njoro, British East Africa (A. T. Cholmley). 



1 S in the British Museum (the six other species here described are in the 

 Tring Musenm). 



The specimen stands intermediate between Hippotion and Basiothia. It has 

 the look of being a hybrid between H. celerio and B. medea. But as the hindwing 

 is more extended black than in either species, and as there is no trace of yellow 

 in the basal area of the underside of the forewing, we believe H. chloris to be an 

 independent species. 



7. Rhagastis rubetra spec nov. 



(??. Third segment of palpus triangular, as in R. acuta Walk. (1856), the 

 apical tnft both on the outer and inner surface longer than in that insect. Centre 

 of head and thorax and the markings of forewing, on upperside, mummy-brown. 

 Underside of wings and sides of breast ferruginous ; underside of abdomen pinkish. 



Wings, above. — Forewing similar to that of R. velata Walk. (1866), the 

 markings prominent ; three subbasal lines, more or less coufluent, the interstices 

 being filled in with mummy-brown, a patch distally of apex of cell, followed before 

 inner margin by some clots representing lines ; halfway between this patch and 

 apex a large costal patch composed of three lines with the interstices partly filled 

 in, these lines continued by some dots situated on the veins, more numerous and 

 merged together at sinus of inner margin ; snbmarginal area more evenly greyish 



than in velata, the distal edge of wing and fringe mummy-brown. Hindwing 



brown, a small, ill-defined patch near anal angle clayish ; fringe white between 

 the veins. 



Underside as in R. acuta, deeper ferruginous. 



Clasper of <? with two or three large friction-scales. Penis-sheath without 

 free processes ; on left side an oblique row of small teeth. 



Hab. Nias. 



One pair.
