the learned French author is right in thinking that two generic 
names are required. In that case the new name will have to take 
the place of Lychrosis, Lacord., as Mr. Pascoe founded his genus 
on the Australian species, for which, therefore, the orig inal name 
must be retained. 
I may add that I have before me several specimens of L. 
luctuosus, Pasc., taken by Mr. J. P. Tepper, near Port Darwin, 
which vary considerably in size (dj-6 lines), and also in markings, 
some of the white spots on the elytra sho^dng much tendency to 
run together into connected lines.

Mr. Pepper's collection of Coleoptera from the X. Territory 
contains examples of a very variable species that appears to be 
this insect. The grey lines running down the elytra mentioned 
in the description of the type are seldom very distinct, and some- 
times quite untraceable, the whole surface being then evenly 
clothed with whitish pubescence. Abraded specimens (and 
judging by their frequency the pubescence seems to be very 
deciduous) are of an uniform shining ferruginous colour. In very 
fresh specimens the antennae are evenly clothed with fine whitish 
pubescence, and their darker colour near the apex (mentioned in 
the description) is not noticeable. The length varies from 5^ 
lines to 8 lines. Several of the specimens before me have traces 
of oblique striae running between feeble rounded carinse down the 
elytra (scarcely evident except in the apical half), and they may 
possibly represent a distinct species,* but I can find no other 
character to distingish them. The abruptly (t.e., suddenly) 
narrowed apex of the elytra, not drawn out to a long point as in 
H. linedla^ nor sub-einarginate as in II. \-lineata, but separately 
obtusely pointed (in some examples separately rounded oil with 
•Possibly H. moratun, Pasc. The sharpness of the apex of the elytra 
seems to vary both in the striated and non -striated specimens.
