THE HEAD. 



Facies or Face, comprises the parts that are included 

 between the prothorax and the labium, or the upper sur- 

 face of the head. It comprises what may be spoken of 

 as the nasiis post-nasus^ frons vertex occiput^ gencB tem- 

 pera oculi and antennce. Only two of these can claim 

 attention in this outline, i. e., the oculi^ or eyes, and the 

 antennoe. 



EYES OF HIVE BEE (maLe). 



The eyes of the adult insect are formed on the most 

 interesting and wonderful plan. They are of three 

 descriptions : 



Simple, conglomerate, and compound. 



1. Simple eyes may be observed in relation to their 

 number, structure, shape, color, magnitude, situation and 

 arra?igement. 



As to their number, they vary from two to sixteen. 

 In the flea, the louse, the harvest-men (Phalangium,) 

 there are only two, but in such as the bird-louse of the 

 goose and some others, there are four ; while such as the 

 spiders and scorpions have eight, and some even as many 

 as sixteen.
