310 IJOVITATES ZOOLOOIOAB XXV. 1918. 



ON A NEW SPECIES OF STICHOPHTHALMA. 

 By lord ROTHSCHILD, F.R.S., Ph.D. 



IN NovTTATES ZooLOGiCAE, vol. xxiii. p. 307. pi. iv. f. 6, I described and 

 figured a 3 Stichophthalma which I considered was the undescribed cJ of St. 

 sparta Nicev. Major Tytler, who has recently returned to England, has brought 

 a considerable series of this insect with him and among them a ? which agrees 

 almost exactly with the 3 and proves my supposed 3 of sparta to be a new 

 species. In describing this fine insect I have much pleasure in naming it after 

 Jlajor Tytler. 



Stichophthalma tytleri sp. nov. 



This species is intermediate between howqua and louisa in position, and 

 between mathilda and louisa in appearance, though it differs from these two latter 

 very much by the cream suffusion of the outer three-fifths of the forewings. I 

 described the S as quoted above, but repeat the description. 



(J. Basal two-fifths of forewing rufous orange, with lines of underside show- 

 ing through, outer three-fifths cream colour with a submarginal row of small 

 arrow-shaped or chevron-shaped sooty brown-grey patches and a marginal 



band of long lunate spots or streaks, apex sooty bro\vn-grey. Hinduing 



basal two-thirds rufous orange, outer tliird rufous buff with large deep black 

 arrow-shaped chevrons. Underside much yellower than in louisa and the lines 

 are much straighter and less crenulated. 



?. Larger ; differs above in the dark basal area of both wings being more 

 brownish orange less rufous ; and in the dark apex, submarginal chevrons, and 

 marginal lunules being larger and more extended. Below it differs in the basal 

 two-fifths and the outer one-sixth of both wings being less orange more cinnamon 

 brownish buff, and the area beyond the Une of oceUi being much more green. 



Length of forewing : o 08 mm., ? 76 mm. Expanse : o 1'13 mm., $ 161 mm. 



Habitat. 1 S Kindat, Burma ; a series of S3, 1 ? Sebong, Manipur, April 

 1913 (Major Tytler), (<J Tring Museum, Sebong, Type).
