HYMENOPTERA — MELLIFERA. 257 
Fig. 89. 

the face of this insect, or in fact of any other species be examined, 
when at rest, there will only be observed a square or other shaped de- 
flexed lip, over or beneath the extremity of which a pair of horny 
jaws will be seen. If, however, the under side of the head of the 
above-mentioned insect be examined, a long slender horny organ 
(jig. 89. 1.) is perceived, which, in its unfolded and extended state, 
constitutes the tongue of the bee. ‘This organ at first appears to 
consist but of a single piece, but it is in fact composed of two separate 
parts, closely uniting along the centre in a straight line (jig. 89. 2.). 
Presently we see the jaws opened, the labrum raised, and this slender 


the terminal lobe of the maxille; dd one of the cardines, d the fulerum, m 2. the 
tubular mentum (tubus K.); z the paraglosse (lacinie interiores K.); and + 
the 4-jointed labial palpi (laciniz exteriores K.); x the epipharynx or epiglottis of 
Savigny, beneath the labrum ; jig. 89. 19. the basal portion of the same apparatus still 
more fully extended; fig. 89. 10. the same organs seen from beneath, o being the 
extremity of the mentum, and oo the base of the labium, the intervening space 
being occupied by the basal dilated muscular portion of the paraglosse; y the 
lora K., or strong muscle whereby the maxilla is protruded; fig. 89. 11. the basal 
portion of the same organs seen from above, to show the situation of the epipharynx 
(x), of which the extremity is recurved, as in fig. 89. 9. x; fig. 89.12. the epipharynx 
removed, and fig. 89. 13. the same laterally, both with the front turned down; fig. 89.14. 
the epipharynx (dotted) separated from the pharyngeal tube, in order to show 
the internal valve (hypopharynx Savigny); fig. 89. 15. the extremity of the tubular 
mentum, with the basal portion of the labium and its lacinize withdrawn into the 
tube as at rest ; fig. 89. 16. a section of the same, to show the manner in which the 
folding of such basal parts is effected ; fig. 89. 17. the extremity of the mentum 
(m 2.), and the base of the labium and its lacinie (z) and palpi (+) fully protruded, 
showing the strong muscles at the base of the laciniz. 
Observ. — The same letters are applied to the same organs throughout all these 
figures.
