 the leaves of a palm tree, in the " compound " of the Indian 

 Museum, Calcutta {Indian Jlhiseum CGllecior, July 28th, 1909,

The antennae of this species are very vai'ial)le; in three speci- 

 mens the second and third a-ntennal joints weie equal in length ; 

 one example possessed only three joints to the antenna^ ; and 

 another specimen had three joints to the right antenna and 

 four to the left. These anomalies are most likely to be explained 

 as being due to the results of regeneration after an injury. 

 The specimens were in each case, so far as could be ascertained, 

 quite mature. 



Pseudosira indrct does not agree fully with the diagnosis of the 

 genus given by Schiitt. The chief points of difference are : 

 («) the jireseuce of teeth to the superior claws of the feet ; 

 (6) the relative length of the joints of the antenn£e ; and (c) the 

 great length of the fourth abdominal segment. As 8chott erected 

 the genus on a single specimen only, some of his generic 

 chai-acters will, I believe, pro\e to l)e of nothing more than 

 specific value. 



Burner* separates Pseiidoxira from *SV/;-« principally by the fact 

 that the dentes are scaled ventrally in the foi'mer and not so in 

 the latter genus. This character along with the hook-like mucro 

 renders the genus Pseudosira easy of I'ecognition.
