510 Mr Warburton, On some new and obscure species 
Neumann has kindly furnished for examination. Therefore it 
appears to me that the species H. bispinosa, Neumann, should be 
restored and the additions made to its diagnosis from the Chinese 
specimens cancelled. Under the circumstances I have thought 
it better to re-describe H. bispinosa from numerous males and 
females taken from domestic animals in India. 
The two forms are so closely allied that unless seen side by 
side they might very easily be confounded, but when apposed the 
distinction is obvious, for there are various small differences 
besides size and chitinisation. Moreover the examination of many 
hundreds of Indian ticks has failed to reveal a single specimen of 
the large form ( H . hystricis ), whereas the small, feebly chitinised 
H. bispinosa (as I believe it to be) is fairly common. I have not, 
however, seen Supino’s type specimens, and only know H. hystricis 
from a specimen ( $ ) kindly lent by Neumann, and another (also 
$ ) in the British Museum named by him. 
Another somewhat obscure species of Haemaphysalis is H. 
papuana, Thorell, but the obscurity entirely arises from wrong 
identifications subsequent to the original description. We have 
received numerous specimens (from Sarawak) of a tick which is 
undoubtedly the true H. papuana, for though some points are 
missed in Thorell’s description, his excellent figures supply the 
deficiencies. Canestrini (1884) confused matters by identifying 
some Queensland ticks as H. papuana , and figuring the ventral 
surface of the female capitulum, but his identification was pro- 
bably quite wrong. The palp appears to be of a different shape, 
and there is no spine under the third article as there is in 
H. papuana. 
In the British Museum there are two gorged female ticks 
labelled H. papuana, which are certainly not this species, but 
apparently something not hitherto described. A diagnosis will 
be found below under the name of H. crassa. H. papuana and 
H. crassa both belong to the H. flciva group. 
Haemaphysalis flava, Neumann 1897. 
Syn. H. flava, var. armata, Neumann 1905. 
(Redescribed from specimens taken in Japan and kindly given 
by Dbnitz.) 
Male: dull yellow, 2 # 1 x 1*4 mm., broadest about the level of 
the spiracles; punctations numerous, of medium size, regularly 
distributed; cervical grooves faint, converging, then separating; 
lateral grooves beginning about half the body length and ending 
immediately behind the spiracles ; festoons long, curved. 
Venter: yellow; spiracles white, oval, with slight blunt dorsal 
protuberance.
