maxillae. Attached to the ends of the cardines are 

 two pieces, the lora (/oriew = rein), which converge 

 towards each other as they pass away from the rods, 

 and eventually meet, so that together they form a 

 V-shaped structure suspended from the rods by the 

 divergent ends of the two limbs of the V. The lora

vary much in length, being much larger in the long- 

 tongued than in the short-tongued bees; in fact in 

 the genera Halictus and Sphecodes no true lora are 

 recognisable. The V formed by the united lora is so 

 articulated to the cardines that it can swing right 

 over ; thus it can either lie between the cardines with
