BUTTERFLIES FROM THE INDO-MALAYAN REGION. 375 



pp. 43 and 44 (1890), both described from unique male examples, 

 S. chalybtia from Chang Yang, and 8. pratti from Ichang, in Central 

 China. A fourth species from the Khasi Hills will probably have 

 to be added, as I have recently received an undoubted female 

 Satsuma from the Rev. Walter A. Hamilton, by whose native 

 collectors it was obtained last year. Most unfortunately, ants, 

 those horrible pests of the tropics, got at this and other specimens 

 of mine on the journey from Bombay to Calcutta, and completely 

 devoured the abdomen. I have, however, had the specimen, which is 

 otherwise quite fresh and perfect, drawn (Plate F, fig. 17, $ ), 

 but owing to its mutilated state, and the females of two out of 

 the hitherto known species of the genus being undescribed, shall not 

 give it a name. It may be described as follows : — Female. Upper- 

 side, both tcings pale blue. Foreicing with the costa broadly black, 

 that colour reaching to the subcostal nervure, the apex very broadly 

 and the outer margin also broadly but decreasingly black. Hindwing 

 with the costa and apex rather broadly, the outer margin narrowly 

 pale fuscous ; a fine black anteciliary thread ; the cilia cinereous. 

 Uxderside, both tcings ferruginous, rather darker on the hindwing. 

 Foreicing with an irregular darker discal line, commencing on the 

 costa and ending on the first median nervule, outwardly defined with 

 whitish ; the inner margin broadly pale fuscous. Hindwing with 

 very indistinct discal and submarginal lines ; the abdominal margin 

 and anal lobe heavily sprinkled with black scales. The upperside 

 of this species agrees with the description of 8. chahjbeia, but 

 the underside is ferruginous not grey, and the forewing has no 

 discoidal spot. The markings and ground-colour of the underside 

 are almost exactly as in Japanese males of 8. frivaldszkyi in my 

 collection, but the latter is considerably paler and the former are far 

 less distinct : whether these are specific or sexual differences I am 

 unable to say. Lederer's figure i ppears to portray a very small 

 female specimen, though he describes it as a male. The figure is 

 very rough and barely recognisable. 



As regards the genus Satsuma I think it should be sunk as a syno- 

 nym of Thecla, Fabricius, as restricted in " The Butterflies of India, 

 Burrnah and Ceylon," vol. iii, p. 207. In neuration it is practically 

 identical with true Thecla. Mr. Murray in his diagnosis of the genus,
