rounded by numerous punctulations. The posterior quadrangle has 

 rounded hind-corners, a rounded hind-margin and a median incision , 

 whicli continues itself for a small part on the animal's back. — 

 The anterior margin of the posterior dorsal shield has no markings 

 and lies over the anterior dorsal shield. — The only and exceedingly 

 minute hairs of this side are: one just in the middle of the anterior 

 margins of the céphalothorax, and one on each shoulder. 



Ventral side. This is quite smooth , polished , having no shields, 

 but only 6 pair of very minute hairs (see my fig. 30). The sense- 

 organ , comparable with the mentum of the ParasUidae, is present, 

 but small, and confused for the greater part with the ventral 

 surface of the head. It bears two hairs wich reach beyond the tip 

 of the rostrum. This is provided with two small rostral hairs. 

 The epimera 1 are fused to form a Y. From the outer and posterior 

 corner of the coxa 2 a chitinous bar runs toward the epimeron 3, 

 which ends in a Y. There are two anal suckers before the sucker- 

 plate. This bears 6 suckers, of which two are large, each with 

 two central little circles. Two smaller ones stand behind, and two 

 other smaller ones to the sides and a little backward of the large 

 ones. Before and outward of the large ones there is an indication 

 of a fourth pair of suckers. Behind the sucker-plate the incision 

 and the posterior margin of the body are dark biown coloured. 

 Legs. The legs are nearly equal in size, being half as long as 

 the animal's greatest breadth. The two fore pairs are slightly 

 thicker than the two hinder pairs. Except one or two hairs , the 

 legs — except the targi — are hairless. All the tarsi have one 

 strong claw and four beautifully curved lanceolate hairs. In fig. 29 

 you may further observe that the tibiae \ and 2 and the tarsi 3 

 and 4 bear a tactil hair as long as the leg. 

 llalntat: Bombus ierrestris.
