According to Moquin-Tandon this species is con¬ 
stantly employed as a vesicant. It lias possibly been 
confounded with L. Courboni.

spots, when denuded black.—

Head moderately large, almost 
roundish four-cornered, spotted, 
black, in some parts thickly co¬ 
vered with greyish-wliite hairs, 
elsewhere bald, and hence apparently spotted, owing 
to the appearance of the colour of the head. Fore¬ 
head slightly arched, with a smooth, bald, brilliant 
longitudinal depression in the middle and broader 
at the lower end. Scutellum slightly arched, 
with a tolerably straight edge behind. Antenme 
one-third shorter than the body, almost bald and 
thread-shaped. The first joint funnel-shaped and 
wedge-shaped, towards the upper part very slightly 
thickened, hairy, only a little longer than the 
second, which is funnel-shaped and hairy. The 
third joint almost cylindrical, about one-third longer 
than the first. The last joint cylindrical, gra¬ 
dually terminating in a bluntisli point. Protho¬ 
rax partially covered, like the head, with greyish- 
white liairS, above elongated and four-cornered, 
at the front end somewhat narrower. Lateral 
edges only slightly apparent and almost straight. 
The upper side with a tolerably considerable longi¬ 
tudinal furrow in the middle. Shield very small, 
three-cornered, almost bald. Wing-covers somewhat 
widened towards the hinder part, black, thickly co¬ 
vered in some places with greyisli-wliite hairs, be¬ 
tween Which there are considerable bald spots. Sto¬ 
mach black, covered with greyish-wliite hairs, which 
are especially thick at the hindermost edge of the 
ring, with moderately large punctiform bald places 
on the middle. Legs slender, black, covered with 
grey hairs at the upper part and especially on the 
under side; upper side of the tarsi with only very 
fine hairs. The antenme and the upper side of the 
tarsi are brownisli-black. At other parts the animal 
appears grey from the hair, and on the head the 
thorax, the under-stomacli and the wing-cases spotted 
black. The spots on the wing-cases are very con¬ 
siderable and distinct; those of the stomach, the 
head and the thorax are smaller; on the two last- 
named parts they are less distinct, 6-7 lines long. 
Punctate Blister Fly, Lytta punctata , Germ.; 
blackish-brown, with a fuscous tomentum; elytra 
studded with numerous points, when naked black.—

smaller. Head oval, fusco-tomentose, with scattered 
puncta, when naked black. Antennae black; thorax 
short, convex, subglobose, channelled dark brown, 
fusco-tomentose, with two black spots. Elytra bark 
brown, densely fusco-tomentose, with numerous, 
scattered, inordinate puncta, black when denuded. 
Body beneath, with the feet, densely tomentose. 
Native of Banda Oriental and Entre Rios. 
Burmeister says that it is very like the Biclio 
moroiv; but the elytra are more strongly marked 
with black dots, and the feet are of the same browm- 
ish-black as the rest of the body. “ I have found 
it, he adds, “in the Banda Oriental and in Entre 
Rios, near the Parana.” He cites it as one of the 
applied vesicants with which he is acquainted.

THE EUCALYPTUS GLOBULUS AND ITS 
USE IN MEDICINE. 
The employment of the Eucalyptus globulus in 
therapeutics is the subject of a very important me¬ 
moir by Professor Gubler, in which he expresses 
an opinion that it will probably prove to be a re¬ 
medy worthy of being ranked with the cinchona 
alkaloids. We take the following particulars from 
the Journal de Pharmacie et de Ghimie for De¬ 
cember :— 
The Eucalyptus globulus belongs to the Natural 
Order Myrtacece, which furnishes the clove ( Garyo- 
phyllus aromaticus), oil of cajuput (Melaleuca minor) ‘ 
and the pimento ( Eugenia Pimento). It is one of 
the noblest representatives of a genus that contains 
upwards of a hundred species. It is often gigantic 
in size, and is impregnated throughout with an aro¬ 
matic substance, which is present, however, in 
smaller proportions in the wood and the bark than 
in the flowers and the leaves. The tree is easily 
acclimatized in the southern provinces of France, 
Corsica, Algiers and Spain, being known in the last- 
named country under the popular name of the fever- 
tree. 
An essential oil, having the formula C 12 H 40 O, is 
obtained from the leaves by distillation, which has 
been named by Cloetz, who investigated its compo¬ 
sition, eucalyptol. The results of this investigation 
have already been printed in this Journal.* Euca¬ 
lyptol has an agreeable, fragrant, aromatic and pecu¬ 
liar odour, which by some has been compared to- 
camphor, by others to rose or lavender. It has an 
aromatic, warm and bitter flavour, accompanied by 
a slight acidity and freshness at the back of the 
throat; when in excess, however, it produces a 
burning sensation, and an increased secretion of sa¬ 
liva. Doses of from two to four grams and upwards 
cause a disturbance of the digestion, sometimes suc¬ 
ceeded by a diarrhoea in which the motions, like the 
eructations, recall the smell of the eucalyptus. 
Large doses sometimes cause headache, excitement 
and fever, with accelerated respiration, thirst, sick¬ 
ness and generally sleeplessness ; upon anaemic 
persons, however, it acts as a narcotic. The symp¬ 
toms rarely last more than a few hours. In most 
cases one to two grams can be tolerated at first, and 
in all cases the patient easily becomes habituated to 
its use. The physiological action of the leaves is 
very similar, and it has been found that they can be 
taken by fresh patients in larger doses than the free 
essence. 
In Australia the Eucalyptus globulus is the popu¬ 
lar remedy for fevers, and in Europe it has been 
used successfully in the treatment of diseases preva¬ 
lent in marshy districts. M. Gubler quotes the tes¬ 
timony of several medical practitioners, who say 
that it produces marvellous results in cases of in¬ 
termittent fevers, especially obstinate ones where sul¬ 
phate of quinine has been used without effect. He-
