GENERAL NOTES. 71 
Museum. Of the fourteen species described (nearly half the 
known species), two are trom this Colony; their description is 
appended. The microscopic structure of the cuticle of both 
species is figured in the paper referred to. 
1. Gordius diblastus, Orley—Female, length 40 centim. ; 
male, length 16-20 centim. Body slender, tapering at both 
extremities, especially posteriorly. The extremities are some- 
what swollen and button-shaped. The tail of the male has two 
lobate processes of nearly equal thickness throughout their 
whole length. Thickening in the region of genital aperture 
inconspicuous. Cuticle with very slightly raised crossing lines, 
and covered with pale spots. 
2. Gordius pachydermus, Orley.—Male, length 16-20 centim. 
This species is especially distinguished by the thickness of its 
cuticle, which is covered with a great many more or less 
elevated papillze of various sizes. No crossing lines are to be 
seen ; and the cuticle appears almost structureless. Body of a 
red-brownish colour, tapering continuously at the extremities, 
especially at the anterior. Semicircular depressions giving rise 
to a superficial segmentation. Tail of the male has two lobate 
very short processes, equally broad throughout their whole 
length, running almost parallel, and not touching each other. 
The horseshoe-shaped thickening in the region of the genital 
aperture inconspicuous. 
CHANGE OF NOMENCLATURE OF Two MOoTHS.—Mr. A. G. 
Butler, of the British Museum, finds that two of our moths 
hitherto known under the names of Polygonia fortinata and 
Selenia gallaria belongs to the genus Azelzna. This genus is 
especially South American, but it occurs all through America 
and the West Indies. It is not known in Australia. 
ADENOCHILUS GRACILIS (Hook, F.)—This rare and curious 
orchid appearsto have been found hithertoonly in the North Island, 
and at one locality. In Hooker’s Handbook of the FI. of Nov. 
Zeal., the only remark as to habitat is: “ Bay of Plenty, Colenso”’; 
and in Mr. Colenso’s paper on the Botany of the North Island, 
in Vol. I. of the N.Z. Inst. Trans., the plant is recorded as found 
near Lake Waikare. With these exceptions, no mention of its 
occurrence has been made in any New Zealand publication. 
It was with much pleasure therefore that I found the plant 
this last January, when botanising in the neighbourhood of Lake 
Hauroto (Howloko), in the south-eastern corner of the South 
Island. It grows in the dense Fagus forest which extends from 
the Waiau river westward to Preservation Inlet, and is asso- 
ciated with Caladema minor. From its small size, and its growing 
among dense patches of soft green moss, Nertera and Corysanthes, 
it is very easily overlooked, except when in flower. It is 
interesting to find that this curious generalized form has so wide 
arange. From the fact of its being found in two so widely 
separated localities, it is probable that its occurrence in inter-
