8«. Danaida juventa Cr. kvakatmiae subsp. iiov. 



Differs from juventa from Java in the much heavier 

 black fuscous markings and larger size. In this respect it 

 is similar to sitah from the Anambas and Malay Peninsula. 

 Differs from sitah in having the fore wing slightly narrower 

 and more pointed, the two large greenish-white spots 

 between the median nervules broader and less elongate ; 

 the white spots forming the double submarginal row in 

 both wings smaller and more similar to those in juventa. 

 Underside fuscous black, lacking the brownish tinge visible 

 in sitah. The Engano form longa' has the discal spots 

 beyond the cell in the fore wing more elongate. The West 

 Sumatran form, robinsoni, is stated to be intermediate 

 between longa and phana from Lombok, and to differ 

 from longa in having all the pale markings on both wings 

 whiter and larger. 



Exp. al. 72-75 mm.

Fruhstorfer describes the " very rare race of the Malay 

 Peninsula " as sinopion (I.e.). His description fits Distant's 

 figure (I.e.) of this species, but neither the figure nor the 

 description agrees with a long series from the Malay Penin- 

 sula examined by me. The localities given above are taken 

 from a series of 84 specimens from the F.M.S. Museums 

 and 20 from the Raffles Museum. I have since examined 

 others from Pahang, Kuala Lipis, and Negri Sembilan, Bukit 

 Tangga (F.M.S. Mus.), and from Selangor, Ginting Simpah 

 and Kuala Selangor (F.M.S. Agric. Dept.). It may there- 

 fore be regarded as a comparatively common species in the 

 Malay Peninsula and well distributed. The rarity of the
