■Wings, covered with cruftaceous elytra, and is fubdlviii- 

 ed into thirty different gener.i, according to the {h:ipe of 

 the antennae. 



The fecond order is called the hennipterous : becaufe 

 tlie wings are half covered with craftaccous elytra, and 

 are lefs hard and robufl: than thofe of the coleopterous 

 infe£ls, but more llrong than thole of the mennbren aceous 

 •winged i ifefts that compofe the fubfequent orders. The 

 upper wings are femi-coriaceous : They do not meet to- 

 gether in a longitudinal future, as in the firll order-, but 

 have part of tiieir interior margin crofled or lapped, the 

 one over the other along the upper part of the abdomen. 

 The mouth and probofcis of the infers of this order, are 

 bent inwards towards the breaft. 



The third order comprehends the various tribes of 

 moths and butterflies, whofe wings are covered wiih im- 

 bricated fcales, and which on that account are called k- 

 pidopterous infedls. Tliey have four membranaceous 

 •wings ; their bodies are rough, and the mouth furnifhed 

 with a fpiral tongue, which they can roll up, or unfold 

 at pleafure. 



The neuvopterous infeds conftitute the fourth order, 

 which comprehends all tliofe genera which have four 

 naked and membranaceous vi'ings, reticulated with veins. 

 The tail of thefe animals is unarmed, having no fling, 

 but is provided with appendices liiie pincers, by which 

 the fexes are diftinguiQied. 



The infefts of the fifth order have the tail armed with 

 a fling', excepting the males, which have not that olfen- 

 five inftrument. They have four membranaceous wings, 

 ^nd are called the liymedopterous infe6ts. 



The fixth order contains the depterous infects, or fuch 



<8S have only t\yo wings : They are farther diftinguilhed
