I am indebted to Mr. Howard Ashton for drawing 

 my attention to the above synonomy. Mr. Ashton pointed 

 out that he could see no difference between tunieri and 

 hirsxitux. I have since exanuned the type of hlrsutu.<, 

 which is in excellent condition in the Madaey Museum, 

 and find that it does not differ in any respect from about 

 50 turneri I have examined. 



The type of liirsiifus bears no collector's label, nor a 

 localitv label other than that written on the name label. 

 The locality South Australia requires confirmation tor 

 this species. 



Hah. Mt. Wellington, Tasmania. South Aus- 

 tralia?? 



The species occurs very abundantlv on the summit of 

 Mt. Wellington during Januar\ and early Februaiy. The 

 females are very scarce. 



DiEMENIANA TILLYARDI, f/i. ntiV. 



Male. Black; head marked as in D. hirsufus; a 

 central elongated spot on pronctum, lateral margins, and 

 two triangular central spots on the mesonotum ochraceous. 

 The mesonotum has a line more or less distinct, running 

 from the pronotum to the nearest corner of each tri- 

 angular spot; these lines are pai'allel. Legs as in V. 

 Iilrsufu^, but the wings differ in having the apex of the 

 anal area bordered with black. The opercula are bor- 

 dered, more or less broadly, ochraceous or testaceous 

 apically (in D. hirsufus they are entrrely black, or at 

 most with an ochraceous- subapical streak). 



Lengfh, 22 mm. ; exp. across wings 51 mm. in the 

 holotype. The measurements vary from 18 mm. long, 

 and 48 mm. expanse in the paratvpes. 



Hah. Cradle Mt., about' 3,000 ft. Jan., 1917. 

 9 males. A specimen was taken bv Mr. R. J. Tillyard, 

 and subsequently eight further si^ecimcns were taken.
