Group ISCHNOCOLE^E. 



This group has been formed on the distinction of the tarsal 

 scopulae being divided by a line of setse ; but, as shown by Mr. 

 Pocock (Ann. & Mag. Nat. Hist. ser. 6, vol. xvi. (1895) pp. 225- 

 230), among those species which in an adult state have an 

 integral scopula, it is always more or less divided in its earlier 

 stages, and also that a considerable number of types of described 

 species of Ischnocolus Auss. are certainly the young of members 

 of other genera ; so that it is possible that this may be the case with 

 the only one recorded in Australia.

This species is unknown to me. It is distinguished (sec. Auss.) 

 by the underside of metatarsus ii. having no spines at the fore 

 end, and by the rear-side and middle eyes being equally large — 

 points also applicable to Selenocosmia crassipes L. Koch. Seleno- 

 cosmia is, of course, easily distinguishable by its stridulatiug organs, 

 which Mr. Pocock has shown (loc. cit.) that several so-called 

 Ischnocoli possess. 



Herr Koch's type of this species is not available. I leave the 

 record as it stands, but the presence of the genus in Australia 

 requires confirmation.
