10 LEMA SEPARATA. 



another oblong larger one occupies the posterior third of 

 the elytra. Underside and legs black , covered with fine 

 greyish pubescence. 



District of Rawas (Sumatra-Expedition). — Two speci- 

 mens of the variety. 



This species which I also possess from Borneo seems 

 closely allied to L. pramsta Fabr. and L. terminata Lac. , 

 from both of which it is separated by its black underside 

 and legs and the want of the anterior transverse groove of 

 the thorax. 



Lema Wallacei, n. sp. 



Black below. Above dark metallic blue. Elytra deeply 

 transversely depressed , strongly punctate-striate. — Length 

 12/3 line. 



Var. a. Entirely black. 



Var. b. Legs fulvous , tarsi black. 



Head impunctate, with a short longitudinal central 

 groove at its anterior portion , the space in front of the 

 eyes finely rugose and opaque. Antennae of half the length 

 of the body, filiform, third and fourth joints equal , black. 

 Thorax not longer than broad , the basilar groove distinct 

 and rather shallow, surface with a few very fine punctu- 

 res. Scutellum oblong, rounded. Elytra deeply transversely 

 depressed below the base, each elytron with ten regular 

 rows of very distinct punctures visible to the apex , the 

 interstice between the 8th and 9th row wider than the 

 others. Legs rather slender. Underside covered with fine 

 greyish pubescence. 



Soepajang and Mesauw (Sumatra-Expedition). — Two 

 specimens of the typical form. 



The small size of this species in connection with its 

 colouration will distinguish it from those found in the 



r^otes I'rom the Leyclen IVIuseuin, Vol. VI.
