116 THE PROCEEDINGS OF THE LINNEAN SOCIETY 



eyes not so much curved as in A. sublimis ; furrows corres- 

 ponding to the legs, and a short deep transverse furrow behind 

 the caput. 



Maxillce much inclined on the labium, and at the upper part 

 broader than long; the upper part is slightly swollen. 



Labium nearly as long as broad, with a slight transverse furrow 

 at the upper part. 



Sternum long and pointed at the posterior part. 



Abdomen triangular, the apex of which is at the spinnerets, 

 and the sides of which are nearly equal ; of a grey colour above, 

 darker on the sides, on which are several black and silvery white 

 lines ; under side same colour, with a dark brown square patch 

 extending from the anterior part almost to the spinnerets ; 

 between these and the posterior part the colour is black with 

 white spots ; legs reddish yellow. 



This specimen is from the " Che vert " Expedition, but the 

 locality where it is found is not given. It seems closely allied to 

 A. sublimis, but the shape of the maxillae and the position of the 

 eyes of the posterior row, apart from the different marking, 

 clearly distinguish it from that species. One specimen, female. 



Theeidium (Walck). 



T. mundulum, (L. Koch). 



T. mundulum, L. Koch, Arach. Aust., p. 263, pi. 22, fig. 3. 



One female found on board ship during the Expedition appears 

 to belong to this species, but is in too bad condition for certain 

 definition ; it probably came on board with plants. The specimen 

 described by Dr. Koch is from Port Mackay. 



T. dubium, n. sp. 



The insect generally of a brownish grey, with dark marking 

 of the same colour. 



Cephalothorax *005 m. long, "0035 m. broad, broadest at the 

 base, narrowing towards the front. 



Eyes placed on two rows curved backwards, the laterals not 

 closer to one another than the intermediates, nearly equal in size 

 and round.
