Pleurarius brachyphyllus, Stoliczka. 



Pleurarius brachyphyllus, Stoliczka, 1873, pp. 152-153. 



This species is not represented in the Van de Poll collection. 



Since compiling the list of localities in my " Account of the Oriental Passalidae " I have 

 •collected specimens in Cochin at Kavalai, ca. 1,300-3,000 ft., and between miles 10 and 14 

 -on the State Forest Tramway, 0-300 ft. M. Guy Babault has presented specimens from near 

 Mahé on the Malabar Coast, and from Kodaikanal in the Palni Hills ; he has also sent for 

 examination specimens from Wallardi in Travancore and from the Coorg region. 



It is doubtful whether P. pilipes, the only other species of the genus described, is really 

 distinct from P. brachyphyllus, although the former is supposed to come from Sumatra and 

 not from India (see Gravely, 1914c, p. 320).
