86 NATURAL ARRANGEMENT OP INSECTS* 



hawk moths, generally so termed (Sphingides), where 

 the antennae are thickest in the middle (&), and gradually 

 narrowed towards each extremity. -^ 2. ^ 



These insects derive their familiar \v a ^r 

 name from the rapidity of their ^^M/^^ 



flight, and from the distant resem- >, Jjlf ^ 

 blance which may be traced in the 

 profile of their heads to that of a 

 hawk ; in general,, they fly only 

 during morning and evening. The 

 third, which is by far the largest 

 division, comprehends the moths 

 (Phal&nides) : these fly only in 

 the dusk of evening, or during 

 the night ; and their antennae gra- 

 duate from the base to a fine point (c). These, as 

 Linnaeus long ago perceived, are the primary divisions, 

 corresponding to our primary circles of the whole order. 

 But as one of these, or the aberrant, is always resolvable 

 into three others, we find that the nocturnal moths ar- 

 range themselves into three great groups, composed of the 

 Bomby tides, or silk moths; the Geometrides, orloopers; 

 and the Noctuides, or night moths. Thus we have 

 three aberrant and two typical groups or tribes, corre- 

 sponding to the quinary divisions of all the other orders. 



(76.) Commencing with the PAPILIONIDES, or first 

 tribe we shall merely observe, that they comprehend all 

 the diurnal butterflies with clavate antennae, or such as 

 were included by Linnaeus under his genus Papilio. 

 These we arrange under five distinct families, which, 

 under the following names, we shall briefly notice ; 

 namely, 1. the Papilionidce ; 2. the Nymphalida ; 3. the 

 SatyridcB ; 4, the Erycinidce ; and, 5. the Hesperidte* 

 The first have six perfect feet, and iuliform larvae ; the 

 second have the anterior feet abortive, and the larvae are 

 scolopendriform : these two being typical ; while the 

 three following are aberrant. 



(77.) The arrangement of the Papilionida into their 

 minor families or divisions has not yet been attempted
