122 Mr. K. I. Pocock on the 



Thelyphonus (Latr.). 



The British Museum has examples of the following species 

 of this genus : — 



Thelyphonus caudatus (Linn.). Java, Hong Kong. 

 ■ linganus, Koch. Sumatra. 



lucanoides, Butler. Borneo. 



johorensis, Oates. Malacca, Singapore. 



■ Schimkewitschii, Tarn. Siam. 



sepiaris, Butler. India, Ceylon. 



donee, Thorell. Sarawak. 



manillanus, Koch. Manilla. 



insulanus, L. Koch. New Hebrides. 



Hosei, sp. n. {Cf. infra.) Borneo. 



anthracinus, sp. n. {Cf infra.) Borneo. 



Tarnanii, sp. n. (Cf infra.) Billiton Island. 



Moreover there is but little doubt that the following species, 

 which are unknown to me, also belong to this section : — 

 Th. asperatus, Thorell, Th. papuanus, Thorell, and Th. aus- 

 tralianus, C. Koch. 



Thelyphonus sepiaris, Butler. 



Thelyphonus sepiarts, Butler, Cist. Ent. i. p. 131 (May 1, 1873). 



Thelyphonus nigrescens, id. ibid. 



Thelyphonus indicus, Stohczka, Journ. As. Soc. Bengal, xlii. p. 138 



(May 28, 1873). 

 Thelyphonus Beddomei, id. ibid. p. 142. 



This species, of which the British Museum has examples 

 from Ceylon, Madras, and Tenasserim, is closely allied to 

 Th. caudatus (Linn.). The males of sepiaris, however, may 

 be readily recognized by the coarse coriaceous texture of the 

 abdominal sterna and by the approximate equality in size of 

 the spines upon the trochanter of the chela. 



Thelyphonus lucanoides, Butler. 



Thelyphonus lucanoides, Butl. Ann. & Mag. Nat. Hist., Sept. 1872, 

 p. 205. 



The male of this species differs from that of Th. caudatus 

 (Linn.) in having the tibial apophysis of the chela long and 

 slender. It is so long, in fact, that when the " hand " is 

 closed against the apophysis the tip of the latter reaches 

 almost as far as the tip of the immovable digit ; moreover 

 the chelae, which are coarsely and closely punctured, are much 

 less robust distally, the tarsus or hand being narrower than 

 the tibia. In addition there are six well-developed spines on 

 the trochanter.
