586 ON THE GKNUS DIPHLEBIA, 



Each of these genera remained monotypic, until the dis- 

 covery of Diphlehio PupJuedides by me, in North Queens- 

 land. In the present paper, two more new species are de- 

 scribed, bringing the total number vip to four. Besides this, 

 I have been enabled to study the life-history of one of these 

 new species in detail, and have also collected a considerable 

 amount of new information concerning the life-history of D. 

 lestdides Selys, vhich fills in the gaps in my original paper on 

 that species, f The facts thus gathered together, afford an 

 opportunity of dealing with the whole genus in one paper, 

 in which the new species may be described, keys given for the 

 ilifferentiation of the four known species, the life-histories of 

 two species related more fully than was before possible, and 

 the characteristics of the genus revised where found necessary. 



Descripfiojr.<< of New Species. — One of these was taken by 

 Mr. F. P. Dodd at Kuranda, in December, 1907. His cap- 

 ture consisted of one mature and one somewhat younger male; 

 the female is not known. The other was first taken by Mr. 

 A. MacCulloch, of the Australian Museum, at Rocky Creek, 

 near Caroda, N.S.W., in 1909. Later on, through the kind- 

 ness of Mr. A. Mack, of Pallal Station, near Bingara, who 

 invited me to make his home my headquarters for a collecting 

 expedition, I was myself enabled to visit this locality, and 

 to obtain a fine series of the insect, and to study its life-his- 

 tory on the spot.
