8 _HETEROMERA, [ Pedinina. 
PEDININA. 
Eleven genera and about one hundred and ten species belonging to 
this tribe are found in Europe, but only one genus and one species oceur 
in Britain; they are by some authors included with the Opatrina, but 
differ in having at least the anterior tarsi of the male pubescent and 
not spinose beneath ; in other points the two tribes very closely resemble 
each other. 
HELIOPATHES, Mulsant. 
In this genus the maxillary palpi have the last joint securiform, and 
the antenne robust and more or less thickened towards apex ; the pos- 
terior femora are moderately long, and the posterior coxee are broadly 
distant ; the anterior tibiee are compressed and much dilated ; upwards 
of fifty species have been described, of which about thirty are found in 
Europe, and the remainder in Northern and Central Asia, China, and 
Algeria. 
The larva of H. gibbus very closely resembles that of Cryptteus quésquilius, and 
does not require a separate description, as it only differs in being slightly broader, 
and in having the head, legs, and ninth segment of abdomen ferruginous ; it is found 
in sandhills. 
H. gibbus, F. (Olocrates gibbus, Muls.). Oblong-oval, convex, 
black, rather shining; head moderately large, closely and distinctly 
punctured, antenne short, moniliform, pitchy red ; thorax transverse, 
with sides slightly rounded, and narrowed behind, closely punctured, 
with obsolete impressions on disc; elytra with punctured striz, and 
broad coarsely punctured interstices, the alternate ones being more or 
less strongly raised; the sculpture of the elytra is often somewhat 
rugose ; legs stout and robust, pitchy black or pitchy red, anterior tibiz 
dilated. L. 6-8 mm. 
Male with the central portion of the abdomen slightly impressed at 
base ; anterior tarsi with the three first joints dilated and tomentose 
beneath.

Deal; Dover; Isle of Wight, Sandown, &e. ; Portsmouth ; Chesil Beach ; Dawlish 
and Exmouth; Burnham, Somerset; Weston-super-Mare; Swansea; Manchester, 
general, on the sandy coasts; Isle of Man; Scotland, very rare, Solway and Clyde

OPATRINA. 
The members of this tribe are distinguished by their excised clypeus, 
small labrum, short and stout antenne which are thickened towards 
apex, and dilatedanterior tibiz, as well as by the spinose under surface 
of all the tarsi ; as above mentioned, they are clesely allied to the 
Pedinina ; ten genera are found in Europe, containing marly fifty
