 wards of 105 mm. in condylo-basal length with a narrowest 

 rostral breadth of 22-23 mm. Tlie type measures —

 area oi: the Darling and Murray Rivers. In S, Queensland 

 also it ranges eastwards nearly or quite to the coast. Type 

 from the Victorian side of the Murray River, opposite 

 Deniliquin, S.W. New South Wales. Other specimens in 

 the Museum from Namoi River, N.S.W. {Gould), Darling 

 Downs (3Irs. T. B. Frost), and Gin-Gin, near Bundaberg, 

 Queensland (^W. Allen).

In connection with this large island race it is of much 

 interest to note that, just a century ago^ Desmarest ^ stated 

 that ^' Les Anglais qui ont passe les montagnes bleues qui 

 entourent le duche de Cumberland, ont rencontre en 

 abondance des ornithorhynques plus grands que celui que 

 nous venons de decrire, et peut-etre d^espece difterente, dans 

 la riviere de Campbell et dans celle de Macquarie." These 

 rivers are tributaries of the Upper Darling.

 the Fhilij^pitiesj and Australia, By G. HuLSTAEHT, 

 M.S.C (Heverlee, Louvain). 



In this paper I propose to describe some new forms of Indo- 

 Australian Lepidoptera. Most of thetn come from Dutch 

 IMew Guinea, Kei, and Tenimber, but there are also a few 

 from Mindanao imd Australia, Besides, I am mentioning 

 a few species nheady known and described previously, but the 

 capture of which might be ot' interest to lepidopterological 

 students.
