250 Miss D. A. Stewart on the Extra- Antarctic 



the specimens at my disposal are all males; however that 

 may be, the two features mentioned above will serve to 

 distinguish this species from any hitherto described. 



The first antenna is very distinctive in appearance, 

 having the basal joint of the flagellum broad and oval, but 

 tapering towards the apex, and the curious form of the second 

 antenna is also worthy of note, the fourth and fifth joints 

 being strikingly longer than the others; this, again, is 

 probably a character peculiar to the male. 



In the possession of a small rostrum and in the size of the 

 eyes this species resembles V. macropis, Bovallius, but the 

 first and second antennae in the two forms are entirely 

 different, and may easily serve to distinguish them. 



The shape of the last ural segment, which has the hinder 

 coiners produced backwards, suggests V. gracilenta, and here 

 again the exceptional size of the eyes only serves to increase 

 the resemblance.

 Vibilia armata, Bovallius, 1887 (1) & (2). 



Localities. Lat. 36° 03£' S., long. 12° 50^ E., Oct. 1st, 

 1901., two males. Lat. 35° 14^ S., long. 15° llf E.,

Vibilia gracilenta, Bovallius. 

 Vibilia gracilenta, Bovallius, 1887 (1) & (2). 



Locally. Lat. 35° 14J' S., long. 15° llf E., Oct, 2nd, 

 1901 (off the Cape of Good Hope), one male. 



In this specimen the produced hinder corners of the last 

 ural segment are not so long as those in the form figured and 

 described by Bovallius, 1887 (2) ; but in all other respects the 

 ' Discovery ' form is in close agreement with his description.
