54 NOTES ON THE PLANTS AND lNSECTS OF KEBGUELEN.

Kerguelen, is enormously abundant in Betsy Cove and about Royal Sound, forming large beds.

The insects we found at Kerguelen were two apterous flies, one as large as a housefly, the other almost as big as a blowfly, an apterous gnat (Czclex) and a winged gnat, a small apterous (or rather very short-winged) moth, two or three beetles (Curculio and Staphylinidze), and three or four spiders (Saltici and a Ti-om- hidhm).

The moth I found crawling upon the beds of the little Juncus. The gnats are to be found about the dead seaweed &c. on the sea- shore. The larger fly nestles at the bases of the leaves of Pringlea, and lays its eggs in the fluid which is caught there. I never found it elsewhere ; but there it is extraordinarily abundant, and every cabbage yielded ten or a dozen specimens. The fly creeps in a slow lazy manner. I am very sorry I did not observi whether it climbs to the inflorescence in sunshiny weather ; perhaps this may be the case. This is an instance of one of those '' neglected opportunities " to which you refer in the ' Flora Antarctica,' as so galling in the retrospect. Even at Heard [ Pong] Island I found the same apterous fly nestling on Pringlea in abundance. Perhaps the two forms have some relation of' mutual benefit.

On one Pringlea plant I found twenty-eight flower-stalks. Three were fresh, of the recent season's growth. The others ap- peared to belong, by their successive amount of decay, to eight preceding seasons. At Christmas Harbour all the Pringlea seed mas unripe, whilst in the inner and sheltered parts of Royal SDund, towards the south of the island, a very large quantity was ripe.

The Leptinella forms immense and luxuriant beds of light bluish green, very conspicuous as seen from seawards on the coast round the rookeries of the shag (Phalacrocorax caruiaculatus), and everywhere thrives and luximiates where the soil is eiiriched by dung. Hence also nearly all the old seal- and sea-elephant rook- eries, so conspicuous from their hummocky appearance, are covered with Leptinebla, which forms a soft bed for the very few o f these beasts which yet remain.
