I9I4-] E. Ellingsen : Indian Ps&udoscorpions. ir 



Cheiridium muscorum, lycach. 



India. Calcutta, i ? , taken in the Museum buildings from a nest of Cypse- 

 liis affiiiis, 27-vii-i909, M. No. ifp. — Dehra Dun (ba.se of W. Himalayas/, 

 i(^, on the wall of a bathroom in Dehra Dun College, M. No. -\\-. 



There is no doubt that this species, of common occurrence in 

 Europe in museums and other buildings, has been imported into 

 India. 



Olpium birmanicum, With. 



Syn.: '.' Olputni biaroliatum, Tomosvar>-. 

 '.' Olpiitm Ortonedae, Ellingsen. 



India. Bomba\-, \$, June, 1911, M. No. if^J ; Bombay: Girgaum, i jun. 

 ( ??), 4-viii-i9i2, M. No. J-ff^. 



Assam. Kannyhati, Shamshernager, Sylhet, 2 ^, collected by G. Mackrell, 

 June 17, 1911, M. No. -ff^- The label in the tube was inscribed; "Caught in 

 box of old books, etc., Kannyhati bungalow, feeding upon the mites which were 

 in abundance round some dead Coleoptera." 



These four Indian specimens (3 & and i immature) certainly 

 belong to With's species. The noteworthy feature as With points 

 out is " a broad transverse stripe " on the cephalothorax. This 

 " transverse stripe" is absolutely invisible as a transverse groove, 

 and is scarcely to be seen when the animal is in a dry state; 

 in alcohol on the contrary- it is more or less visible as an inner 

 division, but also in that case nearly invisible in the middle, 

 though more distinct towards the lateral margins. I observed 

 just the same thing in my specimens of Olpium Ortonedae (from 

 Ecuador, see my description of this species), and on comparing 

 my specimens from Ecuador with the Indian ones, I can find no 

 specific differences between them. Three of the Indian specimens 

 are males ; among the specimens from Ecuador there are also 

 females ; these have their palps somewhat more robust and their 

 galea a little longer. 



The reason that I do not employ the name of Olpium Ortone- 

 dae for the Indian specimens is because another question arises. 

 Are not both species synonymic with Olpium biaroliatum, Tomos- 

 vdry ? With has himself not been without the same sentiment, 

 but finds that Tomosvary's description is "too insufficient for 

 a sure determination." In this he is certainly right, but Tomos- 

 vary's description, short as it is, agrees nevertheless remarkably 

 well, and that Tomosvary may possibly have believed he saw 

 another '' obsolete " transverse stripe, can easily be understood. 

 I should be inclined to unite the three species, and then Tomos- 

 vary's name would have the priority. That I, in spite of this, do 

 not do it, is because With's name for the species is at all events a 

 safe one. Tomosvary's species was from " India orientalis." 



To With's description I shall add the following remarks : I 

 will not, like With, say that the palpal femur wholly lacks a stalk, 

 but that it is rather indistinct, and that all tergites may be divi- 

 ded longitudinally, except the last one. 



The young specimen from Girgaum agrees in all respects with 

 the adult ones, but is of a paler colour and smaller size, and with
