230 REVISION OF THE FAMILY EUSTHENIIDAE (ORDER PKRLARIa). 



EusTHENiA SPECTABiLis EULEGNicA, n. subsp. (Plate xiii.. Fig. 4.). 



I have in my collection a very fine female, from Tyenna, Tas., which is 

 clearly closely related to typical E. spectabllis, but differs in two important points. 

 The radial mark of the forewings is exceptionally well developed, and sends 

 downwards a strong prohingation covering Mo; also the amount of red on the 

 hindwing is greater, and the division between red and black is eulegnie. Expanse, 

 51 mm., cerci 12 mm. long. The locality from which this comes is within the new 

 Tasmanian National Park, at over 1000 feet elevation. It appears well worthy 

 of subspecifii' rank. 



Type: Holotype 5. in Tillyard Collection, Cawthron Institute, Nelson, N.Z. 

 Takenby C. E. Cole, 29.12.1916, at Tyenna, Tasmania. 



EusTHENiA purpurescen.s, n.sp. (Plate xiii.. Fig. li.). 



9. expanse 52 mm. Allied to E. spectabilis, from which it may be at once 

 distinguished by the following characters : — Pronotum with the front and hind 

 borders brown, the former straight in the middle, not so regularly convex as in E, 

 speetabilis. Cerci with the basal joints shorter and less strongly ciliated. Fore- 

 wings without any radial mark; the costal space is purpurescent, with the radius 

 darkly shaded in grey-black; the snbhumeral oval mark is present, whitish touched 

 with jjurple, and followed distally by a blackish patch attached below R and then 

 descending ol)liquely along Cu; the lunule has a rather irregular basal outline, 

 and is widest anteriorly where it ends just beneath R. Tliere is no reticulation 

 of the main veins in pale outline, but the cross-veins beyond the lunule are so 

 marked. In the hindwing, the division between red and purplish black is st)me- 

 what dyslegnic, and is very distinctly augnlated on the vena dividens (Cu2). 



(?, expanse 41 mm.; cerci 16 mm. long, black, downy, with .short, weak cilia, 

 basal joints stout, not as long as wide; superior appendages short, tips somewhat 

 blnnt. Colouration as in ?. 



Types: Holotype ?, and allotype c? in Tillyard Collection, Cawthron Insti- 

 tute, Nelson, N.Z. Taken by G. H. Hardy, 6.12.1913, at Hobart, Tasmania. 



Ilab. — Ta,smania, cliieliy in the soutli. 



EUSTIIENIA PITRPUBBSCEN.S EXTENSA, ll.Sllbsp. 



A fine female taken by Mr. C. E. Cole at Kussell, 'Psismania. on Deo. 2()th, 

 1916, differs from the type in having the red colour of the hindwing spreading 

 <]istally far along the costa, the subhuracral oval mark of the lorewing not so 

 clearly indicated, the pale reticulation present, but weakly formed, on all parts 

 of the forewing, and the lunule not quite .so wide anteriorly. This form appears 

 to be a good subspecies. 



Ty))e: Holotype ?, in Tillyard Collection, Cawthron Institute, Nelson, N.Z. 



As Russell is not far from Tyenna, it appears that, in the elevated National 

 Park area, each species known from the Hobart district is there represented by 

 a distinct subspecies. 



EU.STI1ENIA LUNULATA. n.sp. (Plate xii.. Fig. .3.) 



?, expanse 48 mm. .\llied to E. speetabilis, with which it agrees in general 

 colouration and appearance, but differs in the following important points: — 

 Pronotum dark olive, tlie anterior border not marked with brown, the arabes(|ue 

 sculpture intricate, dissimilar from that of E. s^ycctabilis. Forewings with the 

 pale reticulation moderately well marked everywhere except along the costal
