genus, MoIIika, of wliicli the type is metaJescens L. K. We liave 

 also two species, sent to us bv Mr. Frost, which are described 

 below. 



The spiders are of medium size with the cephalothorax high 

 and convex, the cephalic part being inclined, moderately in 

 auripes, and very steeply in Frost ii. The sides are nearly verti- 

 cal and parallel in front, but widen out someAvhat behind. The 

 quadrangle of the eyes is one-fifth wider than long, and occupies 

 two-fifths of the cephalothorax. It is a little wider in front 

 than behind. The anterior eyes, which are all well separated, 

 form a straight or slightly curved row, and the lateral are more 

 than half as large as the middle eyes. The second row is about 

 halfway between the first and the third, and the third row is as 

 wide as the cephalothorax at that place. 



All of our si:)ecies are from Australia and are represented only 

 by males, two of which, auripes and Frostii, have the legs and 

 palpi heavily fringed.

6. Length 6 mm. Legs 1432. (The male of auripes has 

 the relative length of the legs 4312.) 



This is a very striking and distinct species, from the shape of 

 the cephalothorax. The dorsum is level through half the thor- 

 acic and abouth a fifth of the cephalic part, and from this point 

 the cephalic plate, which is wedge-shaped and highly iridescent, 

 slopes very steeply forward. The sides widen just behind the 

 dorsal eves, and then narrow a2:ain behind. The first row of 

 eyes is straight. The falces are weak, vertical, and liglit brown 

 in color. 



The lower sides of the cephalothorax are reddish bro^vn, with 

 wide snow white bands. The upper sides and the dorsum are 

 dark and iridescent. The clypeus seems to have been covered 

 with white hairs, and the eyes of the first row are of a deep violet 

 color. The abdomen, which under alcohol shows a dark longi- 

 tudinal central band, with a whitish region on each side, when 

 dry, seems to have been covered with a mixture of white and 

 pale yellow hairs, which form no distinct pattern. The legs
