I have already pnintcti mit (11)140, p. 2g3 f«>ot note) that .1. /*/t'o»/«/ii«A. from Sout hem 

 Tena-sMTim, is not really distimt from .1. hi'lfrri from further north. The series from 

 Ttmkin .nhow.s in addition that ./. timnnnt'iisi.i, and .1. himuUnjcimix are no more tlijin 

 in'perfoetly .Heparate<l lo«al races of the same form. Sperimens from northerly liH-alitieH 

 (m'v pi. i, ■' Arrraius, tdln-r sj)p. ) ordinarily have mmh xpiarer and le.s.s slender left outer 

 tuben-lcs than have speiimen.s from further south. But the shape of this tulierele is not 

 altogether eonstant in specimens from a single locality ; and the gradation of the soiithei-n 

 form into the northeni seems t«i he so ••omplete as to render impossible the separation of the 

 spifies even into two definite races.

 One sjM'cimen fp'in I'eiak and one from Borneo. .Mr. ('. Ilolman-lliint has presented 

 It specimen from Bukit Kutu in the Malay Peninsula. Length 35-4 39-5 mm. 



The shape of the left outer lulien le of this species i.s the same as that of the mo.st 

 extreme foim founti among southern specimens of the preceding, of which it is little more 

 than a Io«al ra«e. The size of the posterior convexity of the upper margin <if the left 

 mandible, and the faint median groove on the anterior part of the mentiim, appear. h«»\vever, 

 to afford constant ilistinctive characters liy whicii if may he recognized.
