N'OVITATES ZOOLOUICAE XXII. 1915. 293 



Long. al. ant. : 2U et 2S mm. 



Hab. He Anglaise, Cbagos I., Halomou Islands, Indian Ocean, June 2!', 1905 

 (T. B. Fletcher), 1 ? (type), and Cliago-s Is. (J. S. Gardiner), 1 ?. 



Upperside of body and forewing Front's brown (Ridgway, Nomencl. Colours, 

 j)l. 3. no. 11) shaded with drab, tail slightly darker, nearly burnt umber colour like 

 the marginal band of the hiudwing ; abdomen with three moderately large orange- 

 yellow side-jiatches, lateral tufts of segments .3 and 4 tipped with white, the white 

 pencil of the fourth segment particularly distinct. Palpus below greyish white, 

 breast and centre of abdominal segments grey, sides of venter diflPusely dark brown, 

 in large specimen the venter somewhat worn, creamy-bufF shaded with tawny. 



The generaj coluralion of the iippermde of the wings similar to that of 

 M. conjthiis Walk. (lSo6), but the shape of the forewing differs, the ape.\ being 

 more obtuse and the distal margin more conve.x ; moreover, the drab shading is not 

 quite the same in the outer half of the wing : the brown submarginal band con- 

 tinuous from costal to hinder margin, broadest costally and gradually narrowing, 

 being posteriorly scarcely half as wide as costally, ontside this band the marginal 

 area shaded with drab continuously from ajiex to hinder angle ; none of the markings 



prominent. On hiudwing the yellow band sharply defined, continued to base in 



costal half and to apex at costal margin, in ceutre two-thirds the width of the 

 marginal border. 



Underside paler than in M. cortjtkus ; forewing Mars brown (Ridgway, Xoinenel. 

 Colours, pi. 3. no. 13) shaded with drab, cell and area surrounding it slightly darker, 



extreme base yellowish, on disc a vestige of a line. Hiudwing somewhat brighter 



brown than forewing, suffused with orange-yellow except outer margin, abdominal 

 area pure orange-yellow with the exception of a narrow abdominal edge and a 

 broader anal border, this orange-yellow patch not strongly contrasting witli the rest 

 of the wing on account of the orange-yellow suffusion of the latter. 



The .small specimen (type) collected by T. B. Fletcher has the appearance of 

 being bred, which would account for its small size as compared with the large and 

 somewhat worn specimen obtained by J. S. Gardiner. 



5. Hippotion aurora gloriosana subsp. nov. (PI. XX. fig. 4). 



S. Minor quam //. a. aurora R. k J. (1903), alarum auticarnm margine 

 externo brcviore et linea submarginali magis conspicua. 



Long. al. ant. 31-32 mm., marg. ext. 154-16 mm., lat. 11|-12 mm. 



Hab. Gloriosa Island, N.W. of Madagascar, March 10, 1906 (Meade-AValdo), 

 2 6S. 



The oblique double line which joins the black basal patch is rather less promi- 

 nent than in H. a. aurora from Madagascar, while the subbasal line is deeper 

 olivaceous black. The hiudwing is a trifle paler red, and the black submarginal 

 band a little narrower. On the underside both wings have a row of vein-dots in the 

 clayish butt' area, but no lines. 



The outer margin of the forewing is appreciably shorter than in //. a. aurora, 

 and slightly more angulate before the centre at R-. 



0. Hippotion aurora delicata subsp. nov. 

 S. Praecedenti similis, pallidior, alarum auticarnm lineis una submarginali 

 altera abbreviata obliqua apicali conspicuis, fascia rosacea submarginali alarum 

 posticarum ad marginem oostalem usque continuata.
