Besides the palpi, the tongue is furnished with two slender filaments, called paraglossae (irapa, near, yXivacra, the tongue), which are found also in some other biting insects. The tongue of the bee, * The maxillary palpi and paraglossae are not shown in this figure, butmay be seen in that of Anthophora retusa, in the twelfth chapter. EXTERNAL STRUCTURE OF INSECTS. 33. Profile of Neuter Hive Bee,with the tcngue foldedout of sight. enclosed in its sheath and folded close under the breast, will be easily seen in the first hive or humble bee the reader may examine ; and, if the bee has not been so long killed as to have become stiff, all the parts of the organ can be opened out and displayed by placing a needle below the tongue and drawing it forward. In some bees the labium is com-paratively short, and in differentgenera clelt or acute, as will bedescribed in a later chapter. With the bees we come to theend of the first division of in-sects ; namely, those which havebiting mandibles. In the second division, containingthe insects with suckbig mouths, and without biting jaws,the whole structure of the mouth appears widely stinging proboscis of the gnat, the fleshy blunt trunkof the housefly, the long slender tongue of the butterflv,all these display variation of structure. The tongue in these insects is composed of some orother of the part
