New Sjjecies of Exotic Insects. 
L. acuminatus. 
Obs. — A specimen of this insect, which is said to have been 
named by Fabricius, has been kindly lent me by the Rev. F. W. 
Hope ; its specific characters are as follows : — 
L. pitchy-red ; head pitchy-black, nearly cylindrical, about 
equal in length to the thorax ; coarsely punctured before the eyes, 
the punctures confluent ; transversely furrowed on the posterior 
part ; a large shallow fovea between the eyes. Thorax pitchy- 
red, elongate, nearly cylindrical, slightly narrower in the middle ; 
coarsely punctured anteriorly, the punctures confluent ; trans- 
versely furrowed posteriorly. Elytra about equal in length to 
the head and thorax, and rather broader than the latter ; pitchy- 
red, with an oblique pale spot on each side near the middle ; 
coarsely punctate-striated ; apical spines black. Antennse and 
legs reddish. 
It will be seen upon comparing this description with that of 
Fabricius, that several points have been omitted by the latter ; the 
sculpturing is not detailed, and the oblique pale spots on the 
elytra are altogether unnoticed — these spots consist of pale yel- 
lowish scales. The species is said to inhabit New Zealand ; the 
specimen in Mr. Darwin’s collection was found near Sydney, and 
differs in being of a smaller size, of a more elongate and narrower 
form. The puncturing on the head and thorax is indistinct ; the 
former is black, and the thorax and elytra are nearly red, the 
latter is blackish towards the outer margins ; on each side there 
is an irregular patch of gold-coloured scales, and between this and 
the suture there is another of a smaller size ; these patches form 
an interrupted fascia, situated rather anterior to the middle part 
of the elytra. 
Notwithstanding the difference of form and sculpturing com- 
bined with the different locality, I am loth to pronounce this a 
distinct species upon the examination of a single individual. The 
above remarks, together with an outline figure of Mr. Darwin’s 
specimen, will, however, I hope, enable those who may possess 
specimens, or hereafter find other species, either to identify them 
with the Fabrician species, or point out their distinctions.
