of applying these parts to purposes diiferent from that of feeling. By the antennae they 

 are capable of distinguishing and perceiving, as well as feeling ; and I am strongly inclined 

 to believe, it is by them the males are capable of discovering the females at a great 

 distance. It is certain their powers of perception are very obvious and remarkable, which, 

 bv close observations, we may soon discover ; and unless we allow them capable of smelling 

 without nostrils, I do not know what parts they exercise, or by what means they so 

 readily discover, not only their females but their respective kinds of food, the places proper 

 for depositing their eggs, &c. The male moths appear to have this faculty of discovering 

 their females in a greater degree than most other insects ; for there are but a verv few, if 

 any, belonging to this genus, whose females pass the first night after they quit the 

 chrysalis without coupling with the males ; owing to unconquerable desire in the latter, 

 and the strong effluvia or scent emitted by the former for attracting their mates. Every 

 adept is fully acquainted that a female moth, known by the name of the Egger (Phalsena 

 Quercus of Linnjeus), taken into the fields the first day it is hatched, will most certainly 

 (though shut up in a box) allure all the males round the country that are within the 

 sphere of its attraction, and even from a great distance ; who will at first fly round the 

 box with wonderful swiftness and eagerness, and afterwards settling thereon will hunt and 

 run about it with the greatest impatience, endeavouring to get at the inclosed female ; and 

 all this from the strongest desire of copulation ; for the minute that action is performed by 

 a male, the attractive property of the other ceases. The powers of perception and 

 distinction, therefore, are very great ; and what parts of the insects, unless it be the 

 antennae, are employed in this search I am at a loss to discover. However, at present, I 

 presume it will not be necessary to offer any further reasons for using this term, as the 

 name substituted is sufficient for it to be known by, it will fully answer the intended 

 purpose. 



The names of the other parts are too intelligible to require any explanation. 



The plate annexed (being the last thing I shall speak of) requires but little to be said 

 in its favour. The use and advantage of it is too obvious to dwell on. I have already 

 mentioned, that engravings and delineations claim the preference in the highest degree of 

 verbal descriptions ; and as such, I presume, the reader will find this plate of the greatest 

 service in assisting him to understand the descriptive parts with clearness and ease. I 

 must only recommend it to him, if he is desirous of avoiding difficulty and trouble, to 

 make himself fully acquainted with the terms and names of all the parts of insects, before 

 he begins to read the descriptions.
