bears a semicircular antenna comb. The latter together with the velum 

 constitute the antenna cleaner , through which the antenna may be drawn 

 to remove materials. On the opposite margin of the tibia from the velum 

 is the pollen brush, composed of curved bristles. The last (distal) tarsal 

 segment has claws with a padlike pulvillus between them. The latter 

 secretes a sticky substance for adhering.

 also known as the maxilla. The ligula is known as the glossa or tongue. The 

 flabellum is also known as the bouton or labellum. The labial palps and the 

 ligula together constitute the lower lip or labium. (From Parker and Clarke:

Mesothoracic Leg (Second): The segments are the same as on the 

 first pair of legs. A long pollen spur on the distal end of the tibia is used 

 to remove pollen from the pollen basket and to clean wings. For other I
