10 HETEROMERA. \_MicTOZO>(in. 



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. 



IK. tibiale, F. A small species, oblong oval, not very convex, dull 

 black ; head and thorax very closely sculptured ; antennae 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 tibiae dilated 

 towards apex and toothed externally, anterior tarsi very short. L. 

 3 mm.

 chester (general) ; not recorded from Scotland or Ireland. 



TRACHYSCELINA. 



The members of this family are oval or rounded insects, with at least 

 the anterior tibiae dilated and the apex of the clypeus entire; the 

 antennae are short and somewhat thickened towards apex, and the palpi 

 are not dilated ; the epipleurae 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 Karnt- 

 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 antennae and dilated anterior tibia*. 



The larva of P. cadaverina will be found fully described by myself in the Ento- 

 mologists' Monthly Magazine, vol. xxv. p. 30i ; it is very closely allied to the larva? 

 of Crypticus, ffeliopathes, Opatrum, and other Tenebrionidce ; 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 antennae 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 coiour, 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
