15-20. X. 1915 (FlefcJier); Shillon<?, 5.500-(J400 ft., 29. viii.-5. ix. 

 1915 (Keynj)); Maiigaldai, Assam-JJIiutan Frontier, J31. xii. 1910 

 (Kemp). A short series of both sexes in the; Britisli IMuseum 

 from tlie lo«er ranges, Khasi Hills, Assam, 1878 i^ClicnneU). De 

 Meijere redescribes the species from a single $ from Pattipola, 

 Ceylon, 2000 metres (Biro), in tlie Ilnngariau Museum, arid records 

 the species again from three localities in Java, adding a very 

 useful table of 15 Javanese species (Tijd. v. Ent. Ivii, p. 160, 

 1914). Coquillett records it from Japan. Originally described 

 from China, 



Some specimens of both sexes have the abdominal markings 

 narrowed down to rather line lines of a blue-grey or plumbeous 

 colour, and in these the legs appear to be more brownish than in 

 the more normal specimens. Of this form there are a d and $ in 

 the Indian IMuseum, respectively from Painsur, Garhwal District, 

 W. Himalayas, 7500 ft., 20. iv. 1914 (Ti/thr), and Almora, Knmaon 

 District, W. Himalayas, 5500 ft., 30. ix.-4. x. 1911 (Faiva). 



This species has a very close resemblance to S. adligatas, Wied., 

 which extends from Abyssinia to the Cape and shows a tendency 

 to form races. The chief difference is in the band on the 3rd 

 abdominnl segment, which is broader in adligatus and occupies 

 completely the anterior border, but which in serarius is placed 

 distinctly behind the border. A minor character is in the stigma, 

 which in the African species is more cons]Mcuously black at its 

 inner tMid than in the Eastern one.
