68 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Macro-lcpiduptcra. 



arm of Carnley Harbour. As it is represented by a single specimen only, I am 

 unwilling to denude the wings in order to accurately determine the neuration. 

 Hence I cannot be sure that it is correctly referred to the genus Xdntlidflioc. 



Xanthorhoe orophylloides, n. sp. (Plate II, fig. 12.) 



The expansion of the wings is 1| in. The head is brownish-grey. The antennae 

 are moderately bipectinated. The thorax and abdomen are pale grey, the latter 

 with the segmental divisions dull ochreous ; there are also two black dots on the 

 back of each segment. The forewings are rather narrow, with the apex somewhat 

 acute, and the termen slightly curved oblique, pale bluish-grey with pale brownish- 

 black markings ; a rather faint transverse line at about ^ strongly marked on the 

 cell by a cloudy wedge-shaped mark ; o stronger transverse line at | well marked by 

 a series of dark marks on each of the veins, those nearest the cell being considerably 

 larger than the rest ; a fairly distinct terminal shading of dark grey and a large 

 wedge-shaped pale apical area ; the median band generally is paler and browner than 

 the rest of the wing. The hindwings are pale grey. The cilia are greyish-white, with 

 a few brownish-black scales only. 



This species is very closely allied to Xanthorhoe orophylUi and A", rosearia, but 

 may be easily separated from either by its narrower wings. One male specimen 

 only was captured by Captain Dorrien-Smith, at the head of the North Arm of 

 Carnley Harbour. I have also several specimens of what appear to be faded and 

 worn individuals of the same sjaecies from Campbell Island. These were captured 

 by Messrs. Des Barres and Chambers during the summer following the departure 

 of the expedition from the islands. 



Melanchra erebia, n. sp. (Plate II, fig. 15.) 



The expansion of the wings is a little over If in. The head is very roughly 

 scaled, with tufts of scales at the bases of the antennae, brownish-red mixed with 

 black. The palpi are rather short, slender, tipped with dull wliite. The antennae 

 are serrate, each serration being clothed with two extremely fine hairs. The thorax 

 is reddish-grey, with moderate anterior crest and two rather prominent reddish- 

 brown and black lateral markings. The abdomen is dull brownish-grey. The fore- 

 wings are moderately broad, with the apex roimded and the termen moderately 

 bowed ; dull grey ivith black markings, speckled with reddish-brown scales, especially 

 near the base ; a broad much-broken transverse line at the base ; a wavy. l)roacl. 

 shaded transverse line at about ^ connected with the first transverse line near the 

 costa and termen ; a broad pale central band ; o branched transverse line, the two 

 branches starting at f and f of costa respectively, uniting near the middle of the wing, 

 and reaching the dorsum at about | ; this line is very deeply indented towards the 

 termen ; a subterminal row of blackish dots. The hindwings are dark brownish- 

 grey. The cilia of all the wings appear to be pale brownish-ochreous. 



The single specimen, which, unfortunately, is not in the best condition, was 

 captured by Mr. Browne in the forest on the shores of Erebus Cove, at Port Ross, 

 Auckland Island.
