NOTOXUS, Geoffroy. 
The species belonging to this genus may be easily known by the 
peculiar prolongation of the anterior portion of the thorax over the 
head into a strong horn,* and the longer last joint of the antenne; they 
are about fifty in number, and are very widely distributed, represen- 
tatives occurring in North America, Siberia and Central Asia, Egypt, 
Algeria and the Cape of Good Hope, the Australian region, &c.; of the 
thirteen European species only one is found in Britain ; it is a very 
common insect in sandhills near the coast in many localities. 
N. monoceros, L. Moderately convex, clothed with scanty villose 
whitish pubescence, rather shining, rufo-testaceous, with the head, 
thoracic horn and more or less of thorax fuscous-black or fuscous, and 
the elytra with varying black spots or markings ; as a rule, the scutel- 
lary region, a patch on each side often confluent with this, the middle 
of suture, and a patch on each side behind middle are black ; the mark- 
ings, however, are very variable, and a not uncommon variety occurs in 
which the elytra are entirely black except apex; head rather large, 
narrowed behind, antennez long, filiform, rufo-testaceous ; thorax convex, 
rounded in front and narrowed behind, with the horn obsoletely serrate 
at sides, thickly punctured; elytra subparallel, truncate at apex, 
closely and distinctly punctured ; legs moderately long, rufo-testaceous. 
L. 33-4 mm. 
Male with the thoracic horn more parallel-sided than in the female, 
Sandy places; at roots of grass, in moss, &c., both inland and on the coast ; some- 
what local, but not uncommon and widely distributed ; Stephens records it as found 
in lanes on oaks; I have only found it on sandhills near the sea. London district,

ANTHICUS, Paykull. 
This is a very large and extensive genus, containing more than three 
hundred species, which appear to be found in almost all quarters of the 
world ; no less than one hundred and fifty occur in Europe, of which 
nine are represented in Britain; they are small insects, and at first sight 
many of them bear a strong resemblance to certain species of ants by 
reason of their large head and narrow thorax; they are very variable in 
colour, a large number being unicolorous black or brown, and many 
being rather brightly variegated with red or yellowish markings ; they 
* Abnormal specimens occur rarely, in which the horn is divided and forked,
