femur, tibia, and a ring at the distal end of the metatarsus rufous, 

 the remainder being pale ; in the female the rufous is not so dark 

 as in the male. The other legs are pale. The palpus of the male 

 is black covered A^ith white hairs, excepting the tarsus, which is 

 pale. The palpus of the female is all pale. In both sexes the falces 

 are dark rufous and glossy.

A cosmopolitan species. 



Anoka, gen. nov. 



The cephalothorax is not high and is not much longer than 

 wide ; the sides widen out gradually from the lateral eyes to their 

 \^'idest point, which is behind the dorsal eyes ; they slant outward 

 more widely iu the thoracic than in the cephalic part. The 

 cephalic part is inchned forward ; the thoracic is level for two- 

 thii'ds of its length and then falls rather steeply. The quadrangle 

 of the eyes is one-thu'd ^^-ider than long, is a little wider behind 

 than in front, and occupies two-fifths of the cephalothorax. The 

 first row of eyes is straight, Avith the middle eyes subtouching and 

 less than twice as large as the lateral, which are a little separated 

 from them. The second row is about halfway between the first 

 and third rows. The third row is narrower than the cephalothorax 

 at that place, the eyes being a little farther from each other than 

 from the lateral borders. Abdomen long and slender. 



We have species of Anol-a from various parts of the United 

 States, from Jamaica, St. Vincent, Barbados, and New Granada. 

 They all resemble each other very strongly, even the patterns and 

 colours being often reproduced. The relative length of the legs ia 

 1, 4, 2, 3 or 1, 4, 3, 2 in both sexes. The males are more slender 

 than the females and have the first legs much longer and stouter 

 than the others and, usually, dark coloured, the other legs being pale. 

 The males also, in all the species except A. mifrafa and an unpub- 

 lished species from Jamaica, have the falces long and horizontal ; 

 in the Jamaica species they are oblique, and mitrata has the falces 

 vertical and the first legs pale. The mouth-parts are always dark 

 coloured. 



Anoka is related to Icius and Menemerus, but in Icius the eyes 

 of the first row are larger, the cephalothorax has the sides more 

 nearly parallel and the thoracic part differently shaped (see 

 drawing), and the abdomen is not so long and slender. In Menemenis 

 the sides dilate suddenly behind the third row of eyes, the thoracic 

 part slants more steeply from the dorsal eyes and is wider behind, 

 although not so wide as in Icius, and the cephalic part is more 

 steeply inclined.
