204 Geodephaga. INSECTS. Manticokid^. 
I. Tongue and appendages united throughout their whole 
extent, ...... Panageides.* 
Beautiful insects, especially two fine metallic South 
American species with fiery elytra. 
II. Tongue partly free. 
Head not widened in front; body very often pubescent. 
Clilceniides.* 
Another set of insects with fine colours, and a soft 
downy aspect. Head widened in front ; body always 
smooth, ...... Licinides* 
In the sixth section the elytra are entire or simply 
sinuated at the tip. The fore tarsi are sometimes 
simple in both sexes, sometimes dilated. The number 
of the dilated joints, their form and clothing on the 
under side, are variable. 
I. Mandibles short, or moderate, . . CnieTnacaathides. 
II. Mandibles elongated, ..... Stomides. 
Placed by Waterhouse in the FeroniidcB close to Broscus. 
In the seventh section the first four joints of the 
fore tarsi, and often the intermediate, are more or less 
dilated in the males. They are triangular or heart- 
shaped. Their garniture on the under side is variable. 
I. Anterior tarsi of the males simply ciliated or spiny 
beneath, ..... Cratocerides. 
II. The same, furnished with brushes of hairs, Anisodactylides. 
III. Anterior tarsi of males furnished with scales, Ilarpalides. 
There are sixty-four species in Britain placed in the 
genera Anisodactylus, Diaehromus, Harpalus, Steno- 
lophus, Bradycellus, Trechus, and Aepus. Before me is 
ThdLassopldlus Whitei, a rare Madeiran insect, figured 
and described by T. Vernon Wollaston, Esq. I insert 
its figure elsewhere. 
In the eighth section the three first joints (rareiy the 
two first) of the fore tarsi are dilated in the males, and 
almost always furnished with scales below. The inter- 
mediate tarsi are constantly simple. 
I. The three first joints of the fore tarsi in the males dilated. 
a Tongue and appendages united, . Pseudo-feronides. 
aa Tongue free at the tip. 
b Mentum very feebly, scarcely notched, Trigonotomides. 
hb Mentum, notched in the usual way. 
c Fore tibia more or less robust, and dilated at the end, 
Feronides. 
There are fifty-one British species in genera Amara, 
Pterostichus, Broscus, Lahrus, &c. 
cc Fore tibia more or less slender ; anterior tarsi of males 
furnished with brushes of hairs beneath, Antare- 
tildes. 
Anterior tarsi of males furnished with scales, Ancho- 
menides. (See Panagceides.) 
II. The two first joints of fore tarsi dilated in the males, 
Pogonides. (See Chlceniidx.) 
In the ninth and last section the last joint of the 
palpi is in nearly all very small and slender, and appears 
as if planted in the end of the preceding joint, which is 
of considerable size. The elytra are entire, and the 
tarsi of the males are of variable form, often with the 
first joint much dilated. Lacordaire divides the section 
into two tribes, 
I. Last joint of palpi not acicular, . . Anclimoderides. 
II. Last joint of palpi acicular, . . Bemhidiides. 
There are fifty three British species in the genera Blenius, 
Cillenum, Bembidium, and Tachypus. 
This is an enormously large group of insects, much 
* With Anchomenus placed in one family by Mr. Water- 
house. Chlceniidm containing fifty-six species in the genera 
Panagasus, Loritxra, Licinus, Badister, CalUstus, Clilcenius, 
Obdes, Pngonus, Patrohus, Pristonychus, Sphodrus, Calathus, 
and Taphria. 
Studied by the Count Dejean, and more recently by Mr. 
Tatum and the Baron Chaudoir. 
I now proceed to notice a few members of this great 
section of beetles. 
The Eev. Mr. Dawson has published a valuable 
work on the British Geodephaga. How desirable that 
a similar work on the remaining groups should be 
published, now that we have a list by Mr. Waterhouse, 
published in 1861, it is indispensable as a guide. 
Family— MANTICOEIDHil. 
Platychile. — This genus is African ; it is a flat, pale 
insect, usually placed at the beginning of the Geode- 
phaga. It is very rare in collections, and must be 
nocturnal, judging from its colour, or may come from 
the coast of some seldom visited part of South Africa. 
Manticora. — This genus — fig. 61 — is peculiarly 
African. The larger species must be formidable 
opponents to caterpillars and the grubs of insects. 
Fig. 61. 
Three or more good species are figured. Mr. Thomson, 
in his fine work on Cicindelidce, has figured several 
species. 
Omus, — The genus is indigenous to the west coast of 
America, California, and Vancouver’s Island. I have 
seen many specimens of a species of this genus from the 
latter locality. 
Megacephala. — This is an extensive genus, or 
rather group, allied to the Tiger beetles, and resembling 
them closely in habit. The body is much more robust, 
the head and thorax are broader and stronger, the 
upper lip is short and transverse, and the mandibles 
are stronger, which shows that they prey upon larger 
insects, and require greater force to tear their food in 
pieces; the antennae are longer, more tapering, and 
the legs more robust than in the other Tiger beetles. 
Mr. Bates, who collected so assiduously on the banks 
of the Amazon from the sea to Ega, and beyond it, 
and who spent eleven years making researches on the 
entomology of that fine tropical region, took eleven 
species. He describes them as being all natives of 
sandy soils in exposed situations, as he never met with 
a specimen in the shades of the moist forests, which 
cover nearly the whole surface of the country. They 
appear to be all nocturnal in their habits. During the 
day they are concealed several inches deep in burrows 
in the sand. Although possessed of wings, he never 
observed any one make use of them ; but he adds, 
“ their powers of running exceed anything I have ever 
observed in locomotion ; they run in a serpentine course 
over the smooth sand, and when closely pursued in 
endeavouring to seize them, they are apt to turn sud- 
denly back, and thus baffle the most practised hand
