and Australian Lepidoptera. 459 



pale rusty reddish, mottled with ferruginous ; the basal area 

 bounded externally by a pale-bordered postmedian ferrugi- 

 nous line, deeper in colour than the basal area ; a marginal 

 line, and indications of a submarginal line, ferruginous : pri- 

 maries with the ocelli less distinct than above, an additional 

 smaller indistinct ocellus above and below the subapical one : 

 secondaries with an irregular ferruginous line crossing the 

 cell ; discal dots more distinct than above, more or less pupil- 

 lated with white. Expanse of wings 1 inch 10 to 11 lines. 



Lake Nyassa. Type, B.M. 



Allied to M. eliasis. 



2. Teracolus mutans^ n. sp. 



. Allied to T. vesta ; the markings above the same, but the 

 coloration quite different, linking it to T. protomediaj T. 

 coUageneSy &c. 



Wings above sulphur-yellow, the base shaded (but not 

 broadly) with lilacine gray ; primaries tinted towards the base 

 with pale salmon-colour ; otherwise as in T. vesta. Expanse 

 of wings 2 inches. 



Lake Nyassa. Type, B.M. 



My prediction respecting the unbroken chain of nearly allied 

 species in this genus is being rapidly fulfilled ; since the pub- 

 lication of my paper on Teracolus we have received no less 

 than five of the missing links appertaining to this section of 

 the genus alone. 



3. Teracolus argillaceusj n. sp. 



Allied to T. vesta, but smaller, whiter at the base, much less 

 dusted with blackish ; markings the same : below with the 

 apical area of primaries and the whole of the secondaries, ex- 

 cepting a slightly yellowish central band (enclosed by the two 

 central angular bars), reddish clay-colour ; darker markings 

 below much less distinct. Expanse of wings 1 inch 7 lines. 



Natal {Buxton). Type, B.M. 



This species is intermediate between T. vesta and T. chry- 

 sonomCf although most nearly allied to the former of the two. 

 We have two examples ; and Mr. Buxton tells me that he has 

 others amongst his duplicates. From the upper surface alone 

 it might be mistaken for a pale form of T. vesta ; but the colora- 

 tion of the under surface is very distinct. 



4, Papilto nyassce, n. sp. 



Intermediate between P. policenes and P. antheus : green 

 and black. Markings of the primaries as in P. policenes, ex- 

 cepting that the bands which cross the cell are zigzag, as in
