10 HETEROMERA. [ Mierozoum. 
Opatrum by the ovate last joint of their maxillary palpi; only three 
species appear to have been described, from Europe, Central Asia, and 
Algeria respectively. 
IM. tibiale, F. A small species, oblong oval, not very convex, dull 
black ; head and thorax very closely sculptured ; antennz very short, 
much thickened towards apex ; thorax transverse, with sides rounded in 
front, broadest before middle, with three impunctate spots on disc, and 
a rather deep impression on each side near base behind ; elytra not very 
closely punctured, finely shagreened between punctures, and coarsely, 
but somewhat indistinctly, rugose ; legs robust, all the tibiz dilated 
towards apex and toothed externally, anterior tarsi very short. L. 
3mm. 
Sandy places; asarule on the coast, but also found inland; locally common ;

Kidderminster ; Swansea; Borth, near Aberystwith; Ripon; Liverpool; Man- 
chester (general) ; not recorded from Scotland or Ireland. 
TRACHYSCELINA. 
The members of this family are oval or rounded insects, with at least 
the anterior tibize dilated and the apex of the clypeus entire; the 
antennz are short and somewhat thickened towards apex, and the palpi 
are not dilated; the epipleure of the elytra are narrow ; all the legs are 
stout, and the tarsi are setose beneath ; four species and twelve genera 
are found in Europe, of which one genus represented by one species 
occurs in Britain. 
PHALERIA, Latreille. 
This genus contains more than thirty species, of which seven are 
found in Europe, and the remainder are widely distributed from Kamt- 
schatka to Madagascar; species have been recorded from the Canary 
Islands, the Cape of Good Hope, Brazil, Chili, the Galapagos Islands, 
North America, &c. ; the single British species may easily be known by 
its oval and convex form and light testaceous colour, as well as by its 
short antenne and dilated anterior tibiz. 
The larva of P. cadaverina will be found fully described by myself in the Ento- 
mologists’ Monthly Magazine, vol. xxv. p. 304; it is very closely allied to the larvae 
of Crypticus, Heliopathes, Opatrum, and other Tenebrionide ; it is found with the 
perfect insect in sand under sea-weed and shore refuse; when disturbed it feigns 
death, and lies perfectly motionless for some time; under a high power, however, it 
will be noticed that the antenne and usually the legs are constantly quivering, and 
immediately the danger appears to be past, the insect turns quickly over and, bur- 
rowing rapidly in the sand, soon disappears from view. The following is an abridged 
description of the larva:—Length, 11-12 mm. ; elongate, linear, scarcely narrower 
behind, of a lighter or darker ochreous colour, with the head dark brown, and the 
mandibles almost black ; the claws also and spines of the legs are dark ; head broad, 
ocelli black, rather large, three in number on each side, placed close together in a
