One specimen ticketed " Flooded area, King River, N.T.; W. 

 McLennan ; 24.12.15." Among the specimens sent by Mr. 

 Kershaw, as taken at the same place and time, was a specimen of 

 L. doddi of typical form. In L. doddi, the number of foveas in 

 the juxta-sutural row varies (in one of my specimens there are 

 only two fovese); therefore it is possible they may be altogether 

 wanting sometimes; but, even if this be the case, a varietal name 

 for the form with only three rows of foveae on each elytron will 

 be convenient.

 Carenum fulgidum, n.sp.

 space and sides of lateral frontal spaces purplish-black; pronotum 

 aeneous (cupreous along anterior transverse impression and 

 towards base), disc on each side of suture and anterior margin 

 before transverse impression purple-black ; elytra cupreous, 

 (aeneous in some lights) purple-black on disc ; undersurface 

 of head viridescent on each side; prosternum black in middle, 

 green on each side, episterna green; mesosternum, metasternum, 

 and legs black; ventral segments green, black in middle. 



Head convex (3-7 mm. across eyes), transversely impressed

■■■ Carenum Jloridum, nom.nov., for C. lepidum Sloane, 1916. The name 

 C. lepidum had been used by me for a species of Carenum in 1889. The 

 name C. Jloridum is now proposed to replace that of the second species so 

 named.
