Scorpio bengaknsis of C. Kocli (loc. cit. ix., pp. 3-5, fig. 696) from 

 Bengal, was by Simon referred to the genus Palamnceus. The British 

 Museum has, however, five examples ( 1^ $ 3 (5 ) of a scorpion from 

 Beno-al which, to my mind, is certainly the species described by Koch 

 Two of these specimens present the reddish-brown colouring of 

 C. Koch's example, but this colouring , is purely a question of date 

 from the time of moulting ; the others have the characteristic deep 

 green tint more or less shaded with ferruginous. 



The sculpturing of the hand in this species calls to mind the reticu- 

 lated pattern of this segment in Sc. incUcus, but the ornamentation 

 is much coarser and more distinctly tubercular. 



Scorpio indims,lAmi:{Th.oxe]l, Ann. Mus. Genov., (2), YI, pp. 

 412-414) {=cyaneus and reticulatus, C. Koch, op. cit., III., p. 75 and 

 lY., p. 25) is typically a Javan species. I have merely included it in 

 the accompanying table on the strength of a specimen in the British 

 Museum collection, which is ticketed Ceylon. 



The only described oriental species of this genus which has not 

 been here considered, is Scorpio humilis of Simon (Ann. Soc. Ent. Fr., 

 (5), YII. (1877) p. 94-95) from Manilla. But judging from its distri- 

 bution and from certain characters that are mentioned in the 

 description, I am inclined to suspect that it is a young Palamnceus 

 and not a Scorpio,
