 often sought for, particularly at night.*

Early in November, the first species named above was found on the 

 leaves of the Kerguelen cabbage [Pringlea antiscorhidica), and thereafter 

 in increasing numbers. The insects are of considerable size, dark brown 

 in color, with long legs, and considerable activity of movement, looking 

 not unlike large ants. This species is distinguished on superficial ex- 

 amination by its long ovipositor, and by the prominent pubescence 

 covering its abdomen. Upon the approach of the observer the_ insects 

 drop from the leaves in great numbers, doubling up their legs and coun- 

 terfeiting death. As the axils of these large leaves always contain a 

 considerable quantity of water, the utility of the pubescence with which 

 the insects are covered becomes very apparent, protecting them from 

 getting wet by the film of air entangled in the hairs. Footless larvae, 

 supposed to belong to these insects, were found in abundance among 

 the damp roots of moss and grass. 



On the 27th of November, I set a jar with its rim even with the sur- 

 face of "the earth and baited it with carrion in the hope of catching 

 beetles. It contained, in the morning, large numbers of Diptera of the 

 second species {Anatalanta aptera), differing superficially from the pre- 

 ceding by their lesser size, darker color, less pubescence, and much less 

 distinct ovipositors. They were also much more active in their move- 

 ments, and almost always found ujion dead animal matter. They were 

 not observed to counterfeit death on being approached. 



It was not until late in December that the third species was dis- 

 covered on wet rocks at the edge of the sea. These are smaller than 

 either of the others, quite black, not visibly pubescent, and provided
