3 1 2 Proposal for the Estallishmeni of 



unquestionable characters of instinct, of a superior power 

 which directs their voluntary exertions, both to the suste- 

 nance of individuals and to the preservation of species, must 

 excite strong interest in the student of Natural Theology. 

 For the sake of brevity, I shall here give only a general re- 

 ference to Paley, chap. xix. p. 346. 



Orper I. Coleoptera. Sheath wings, like chafers ; the 

 upper wing covers are called elytra ; these, in 

 most, cover' the abdomen; but in some are 

 partial, as in the earwig. 

 II. Hemiptera. Elytra half membranaceous, half 

 crustaceous, incumbent on each other. Grass- 

 hoppers are of this order. 



III. Lepidoptera. Four membranous wings, scaly or 



powdered. Butterflies. 



IV. Neuroptera. Membranous wings reticulated with. 



nerves, without sting. Dragon Flies, Sec. 

 V. Hymenoptera. Four transparent wings, with 



stings. Bees, &c. 

 VI. Diptera. With only two wings; but with alteres, 

 or poisers, instead of under wings. Flies, 

 Gnats, Sec. 

 VII. Aptera. Without wings. Spiders, Scorpions, 

 Fleas, Lobsters, &c. 



CLASS VI. VERMES. 

 One ventricle without an auricle ; a cold colourless sanies for 

 blood. " The play of the rings in an earth worm as it 

 crawls; the undulatory motion propagated along the 

 body ; the beards or prickles with which the annuli are 

 armed, and which the animal can either shut up close to 

 its body, or let out to lay hold of the roughnesses of the 

 surface on which it creeps — afford, when compared with 

 the provisions for motion in other animals, proofs of new 

 and appropriate mechanism." — Paley, 313. 



Order I. Intest'ma. IT. MoUusca. III. Testacea. IV. Li-. 

 thophi/ta. V. Zocplnjta.
