1 Waterhouse and Lyell, Australian Hesperidae. 227 



Except for the somewhat larger orange spots, the somewhat 

 less acute apex, and the more convex termen of forewing, the 

 female differs but slightly from the male. 



The three allied species T. maheta, T. phigalioides, and 

 T. iacchoides and the less closely related T. phigalia, will be 

 somewhat puzzling to those collectors who possess but few 

 examples, and the following notes should therefore prove 

 useful. 



T. maheta is sexually dimorphic, the male only having the 

 bright silvery spots on the undersurface of the hindwing. 

 T. iacchoides has small, but more and differently placed (to 

 T. maheta), spots on the hindwing beneath, and they are silvery 

 in both sexes. T. phigalioides and T. phigalia are without any 

 trace of silvery spots. The female of T. phigalioides and in 

 lesser degree that of T. phigalia, closely resembles the female of 

 T. maheta. 



T. maheta is known from Kuranda, in Northern Queensland, 

 to Jervis Bay, and we have a single record as far south as 

 Wilson's Promontory : it has two broods yearly and is taken 

 (in Sydney) from September to April. 



T. iacchoides is only known from the Blue Mountains, Como, 

 and Pambula (all in New South Wales), and is single brooded ; 

 September to January. 



T. phigalioides has been taken at Beaconsfield (1,000 feet) and 

 Gisborne (1,500 feet), Victoria, and at Jenolan Caves (3,000 

 feet). New South Wales, and is single brooded ; November to 

 January. 



T. phigalia is taken in Southern Queensland, in the Blue 

 Mountains, and as a semi-alpine species in Victoria, and is 

 single brooded ; September to December.
