spite of my having myself attributed that difference to a 

 species (11. hdla), which I described in 1890, and before 1 

 had had the opportunity of observing any large proportion 

 of the species now before me. It seems to be invariably the 

 case that if there are 4 laminae in the antennge of the male 

 the 6th joint of the antennae of the female is produced into 

 a lamella representing (not the last joint of the male stipes, 

 but) the basal joint of the male flabellum. In most of these 

 species the 6th joint is so lamelliform in the female that 

 there is no doubt whatever of its being part of the flabellum, 

 but in a few species it is only feebly produced. In the species 

 that I take to be (/H/antea it is scarcely one-third of the 7th 

 joint in length, and in hclUt it is still shorter (scarcely one- 

 fifth) ; but the males of the species in which it is not produced 

 at all in the female I invariably find to have only 3 la- 

 minae. Under these circumstances I feel justified in think- 

 ing that Burmeister was not strictly correct in his state- 

 ment that the flabellum has a different number of joints in 

 the two sexes of H. riif/antea. I am doubtful as to the sex of 

 the unique type of H. Jucifera. The laminae of its flabellum 

 are notably shorter than in the male, and slightly longer 

 than in the female of the species I regard as qmaniea, the 

 basal lamella (the 6th joint of the antennae) being a little 

 more than half the next joint in length. The probability, 

 however, is strongly in favour of its being a female.
