The males have the thorax more ample, and the front legs 

 longer; a beautiful series of eight examples, one with blaek 

 elyira. These Sumatran examples MÜh steel-blue elytra, should 

 aecording io Kraatz be referred to L. potaturia Wiedeni. Zool. 

 Mag. II. 1825 p. 45 (ef. Kraatz in Deuts. E. Z. 1899, Heft 11, 

 p. 345). I think in iliat cavse Crotch's name must sink as a 

 synonym, and also Hrn. Kraatz's P. speyri. The colour of the 

 metasternum is very liable to Variation.
