INSECTS IN THEIR PERFECT STATE. 135

 The Linnsean term and the Linnaean system have, 

 however, prevailed, as the names of all the insect 

 orders at once show by the universal termination

 lated wings ; Hymenoptera, those with transparent 

 wings ; Diptera, those with only two wings ; and 

 so on, through all the orders, even to those without 

 wings, which are of course termed apt era, that 

 is, wingless insects. 



Having examined the modern scientific terms by 

 which the order Lepidoptera has been distinguished, 

 we have next to consider the manner in which it 

 is subdivided. Linnaeus made three grand divi- 

 sions — Papilio, which included the Butterflies, or 

 day-flyers; Sphinx, which included the Hawk-moths, 

 or twilight-flyers ; and Fhalcena, which included all 

 the regular Moths, or night-flyers. These terms 

 have since been superseded as those of divisions, 

 though still preserved as the titles of simple genera ; 

 and in the grand divisions of the order, the form of 

 the antennoe has been definitively adopted as the 

 best mode of forming the leading sections, now re- 

 duced to only two. Thus Bhopolocera includes all 

 the Butterflies, that is, tbose with clubbed antenna?, 

 like those of Butterflies; and lleterocera, those
