LAORIID. (Lagriana, Latreille), a family of Coleopterous Insects 

 of the section Hettromera, the characters of which are : Elytra soft; 

 head and thorax considerably narrower than the elytra, the Utter 

 almost cylindrical, ovate or quadrate, and truncated; antenna: inserted 

 near an emargination of the eyes, either filiform or insensibly larger 

 towards the apex, the terminal joint being longer than the preceding, 

 especially in the male* ; palpi thickened at the tip ; terminal joint of 

 UM maxillary palpi of the form of a reversed trangle ; femora oval 

 and cUvate; tibiae long and slender ; those of the anterior legs often 

 curved ; penultimate joint of the tarsi bilobed and the claws simple. 

 The genus Layria (Fab.), contains those species in which the antenna; 

 are gradually thickened towards the apex, and have the last joint 

 ovate ; the fora part of the head is but little produced, but behind 

 is prolonged and slightly rounded ; the thorax is almost cylindrical 

 or square. 



One specie* of this genus exist* in EngUnd, the Lnyria hirta, an 

 insect not (infrequently found in hedges and woods, and apparently 

 most abundant on the white thorn. It is about 4-12tbs of an inch iu 

 length, of an oval form, with a narrow bead and thorax ; these, as 

 well a* the body beneath, the antenna;, and the legs, are black; 

 elytra are dirty yellow, soft, and pubescent Tho body of the 

 Ice i* rather narrower than that of the females, and the antenna) 



The genus Stalyn (Latreille) also belongs, to the present family, 

 and nonsiets of species which have the body more elongated than 

 those of Layria proper; the antenna) are filiform, and consist of 

 almost cylindrical joint*, the last of which is very long and pointed ; 

 the bead i* considerably produced in front of the eyes, and is 

 abruptly narrowed behind ; the thorax is longer than broad, some- 

 what ovate, but truncated before and behind; the elytra are acutely

 1 (Wared, carious glume* ending in a long (ringed seta. The outer 

 palest end in two lone set*; and with a dor*J geniculated twisted awn.

LAMELLIBKANCHIATA, De Blainville's third order of Actpka- 

 lopkora (Acdphalea Testaces of Cuvier). 



De BlainvUle make* this order consist of the following families : 

 1st, Oilracea (Oysters, Ac.) ; 2nd, Subotracca (Spondylui, Ac.) ; 3rd , 

 Margantacea (VvUella, MaUeui, Ac.); 4th, Mytilacca (Mussels and 

 Pinuas); 6th, Polyodonla, or Arcaeta ; 6th, Submylilatca (Anmlon, 

 Unto, Cardita); 7th, Ckamacca ; 8th, ConcMacca; 9th, Pyloridea; 

 10th, Adetmacca (Pholat, Teredo, Futulana, IK.). 



M. Uang separates the order into two divisions : 



I. Monomyaria. 



Families : 1st, Ostraccs, Cuvier (Ottreada) ; 2nd, Pectinides, 

 Lam. (Pectinida); 3rd, Malleaces, Lam- (MaUelda) ; 4th, Aviculca 

 (Anculidcc).

 LAMELLICORNES (Latreille), one of the sections of the order 

 Coleoptera. The insect* of this section have five joints to all the 

 tarsi. The antenna; are inserted in a small hollow in front of the 

 eyes, short, usually composed of nine or ten joints, the last of which 

 are large and flat, and open like a fan. [COLEOPTEBA.] The number 

 of these lamellated joints varies, but there are generally three. The 

 clypeus is usually very large, and the labrum is small and hidden 

 beneath the clypeua, The anterior tibia) are dentated externally, and 

 the posterior tibiae are often more or less denticulated. The mandibles 

 of some of the species are membranous. 



The larva [COLEOPTEBA] is soft, of a cylindrical form, or nearly so, 

 and has a large vertical head. There are six small legs attached to 

 the thoracic segments. The body is always bent When about to 

 assume the pupa state the larvic inclose themselves iu an oval case 

 formed of particles of earth, rotten wood, or other surrounding 

 substances, which are cemented by a glutinous matter. Some of 

 them live in the ground, and feed upon the roots of plants, and others 

 live in decayed animal and vegetable substances, upon which they 

 feed. The perfect insects also feed upon these substances (many of 

 them are found in dung) ; others feed upon the leaves of plants, or 

 on the flowers. 



Latreillo divides the Lamcllicorues into two great tribes, Scarabaidos 

 and Lucanides. [SC.VIIADAIDJK ; LUCAMIO&] 



LAMELLIROSTRES, Cuvior's name for the great family of the 

 Anali<l<r. [DucKs.] 



LAMIA'CE^E, or LABIA'T.E, Labiatet, a very extensive and 

 important natural order of Exogenous Plants, with irregular unsyin- 

 metrical nionopetalous flowers, and a 4-lobed ovary, clianging to 

 4 seed-like monospermous fruit*. It is technically allied eo nearly to 

 Boragmacete as to differ apparently in little except having regular 

 flowers ; but in nature it belongs to a different series of vegetation. 

 The leaves of Lamiacccc are uniformly opposite, and their stems square 

 or nearly so, and in the greater part of the order tho flowers are dis- 

 posed in short opposite clusters axillary to leaves, and appearing in 

 consequence as if iu whorls. 



The species are generally aromatic and tonic, a property that is in 

 most cases owing to the secretion of a volatile oil in little cysts or 

 glands occupying the leafy organs. The aromatic qualities are familiar 

 to us in the Sago, Marjoram, Thyme, Basil, and similar plants, com- 

 monly cultivated for the service of the kitchen, as condiments ; of 

 Lavender, so much valued for its peculiar fragrance; of Mint and 

 Peppermint, well known for their stimulating power, and of many 

 others. Betony, Ground Ivy, Horeliound, and others are examples of 

 the bitter tonic qualities of such plants ; Rosemary appears to have 

 the specific property of stiffening the hair and encouraging its growth ; 

 iU oil is that which gives the green colour to bear's grease and such 

 pomatums; and Cat-Thyme (Tcucrium marum) and Cat-Mint (Nepeta 

 C'li'ciria) seem to bo genuine feline aphrodisiacs. 



Plants of this order are distributed over all tho warmer and tem- 

 perate part* of the world, generally being herbaceous, and never 

 exceeding the size of small bushes. Mr. Itantham boa given an elaborate 

 view of their geographical distribution, from which it appears that out 

 of 1714 specivs 1 OHO belong to the Eastern hemisphere, and 649 to 

 the Western ; 8 only are Arctic ; 80 inhabit the temperate part* of 

 Europe, 190 Spain, 149 tho Himalayan Mountains, and only 157 the 

 K<|ninuctial regions of both the Old and New World, and those are 

 chiefly mountain plant*. 



LinniGus distributed the genera of Lamiacere through his iJidynamia, 

 flymnoiprrmia, and Diandria Monoyyiiia. Writers on the natural 

 system have devised much better modes of arrangement ; the most
