the first row of eyes to the posterior end. It is a little contracted 

 in front, is widest opposite the dorsal eyes and is truncated be- 

 hind, having a wedge-.shaped appearance. 



The quadrangle of the eyes is usually very much, and is in 

 all cases plainly, wider behind than in front. At its widest 

 point it is one-third wider than long. It occupies two-thirds of 

 the cephalothorax. The anterior eyes are usually small and 

 close together, forming a row which is straight or slightly 

 curved. The middle eyes are nearly twice as large as the lat- 

 eral. The second row is close to the first, being from two to 

 four times as far from the dorsal as from the lateral eyes. The 

 dorsal eyes are much farther (sometimes three or four times as 

 far) from each other as from the lateral borders, and form a row 

 which is as wide as the cephalothorax at that place. 



The relative length of the legs is 1423 or 1432. 



Of this genus we have in our collection Rhene cyanea 

 Hentz, described under the name of Homalattus cyaneus in our 

 paper on the AttidaB of North America, p. 86 ; Rhene insularis 

 P., also described as belonging to Homalattus in our New 

 Genera and Species of the Family Attidte, Proc. Nat. Hist. Soc. 

 of Wis., March, 1885, p. 23; and two new species, callida and 

 vaga.

$. Length, 4.8. Length of cephalothorax, 1.9; width 

 of cephalothorax, 2. 



Legs, 14 23 ; first pair stoutest. 



The quadrangle of the eyes is very much wider behind 

 than in front, and is one-fourth wider behind than it is long. 

 It occupies three-foui'ths of the cephalothorax. The sides round 

 out a little in the anterior part. The cephalothorax is nearly 

 square, and is truncated behind. 



The anterior eyes are small, ii:L a straight, compact row, the 

 middle being barely twice as large as the lateral. The second 

 row is narrower than the first and is close to it. The dorsal 

 eyes are on the sides of the cephalothorax. The falces are ver- 

 tical, short, and rather stout.
