26. Oxyambulyx matti Jord. (Fig. 27, <$ holotype). 



Oxyambulyx matti, Jordan, 1923, p. 188 (North Kanara). 

 Oxyambulyx substrigilis matti, Seitz, 1928, p. 534. 



Seitz (1928, p. 534) regards this insect as a subspecies of 

 0. substrigilis (Westw.), but as it occurs in the same area 

 (North Kanara District of S. India) as 0. substrigilis aglaia 

 Jord., it appears to be more than a geographical race or sub- 

 species. 



Imago. — <£. Intermediate between 0. belli and 0. substrigilis 

 aglaia. Upper side of body and fore wing with a pink tint, 

 less cold grey than in 0. s. aglaia <$, and much less warm tawny 

 than 0. belli. Abdomen with a very faint median line. Fore 

 wing with two blackish- olive subbasal spots, the posterior 

 one larger than the costal spot, its diameter rather longer 

 than the distance of the spot from the fringe of the hind 

 margin ; costal portion of outer antemedian line as oblique

as in 0. s. aglaia, running to lower cell-angle and appearing 

 a,s a continuation of the dark vein R 3 ; proximal discal line 

 just outside upper cell-angle, the second discal line (which 

 is very faint) crossing the stalk of the subcostal fork about 

 1 mm. from SC 5 , both these lines being more proximal than in 

 O.s. aglaia, the two outer bars before hind margin near tornus 

 distant from each other, slightly curved, not forming a horse- 

 shoe mark as in 0. s. aglaia ; before this group of bars no 

 rounded spot, as is usually the case in the $$ of 0. substrigilis 

 from India. Hind wing narrower than in 0. substrigilis ; 

 ground paler yellow, the dark brown basal patch smaller ; 

 abdominal area less shaded with grey ; dark brown median 

 band very distinct, touching lower cell-angle, second band 

 less distinct than in 0. s. aglaia, less crenulate, extending 

 forward to R 1 ; submarginal band vestigial inclusive of its 

 anterior portion, which is present in 0. s. aglaia as a subapical 

 spot or short band ; long scales of fringe more or less extended 

 white or whitish between the veins as in 0. s. aglaia. Underside
