surface. The visible surface is that of a sheath which en- 

 closes a slender, flexible rod, the rod being probably con- 

 cerned with the movements of the organ. 



Paraglossce. — At each side of the glossa, and rising from 

 near its proximal end are two subtransparent lobes or flaps, 

 extending about one-fifth the length of the glossa. These 

 are the paj-aglosscs and are probably homologous with those 

 of the beetle's labium. 



Palpifcrs. — Lying just laterad of the paraglossse, and 

 rising from the distal end of the mentum, are the palpifers, 

 extending forward for about one-half the length of the 

 ligula. 



Labial palpi. — At the distal end of each ^palpifer is a 

 3-segmented labial palpus, the proximal joint being longer 

 than the other two combined. The palpifers and palpi bear 

 a few long hairs, especially on the distal ends.

 of labium and maxillae.
