behind. The thoi-acic jaart falls but little until the posterior 

 end. The posterior slope is hollowed. The .sides are nearly 

 vertical. In the female, the cephalothorax is not so much 

 contracted in front and behind as in the male. The quadrangle 

 of the eyes is one-fifth wider than long, is slightly wider behind 

 than in front, and occupies one-half of the length of the cephal- 

 othorax. The first row is straight ; the eyes are large, the 

 middle being nearly double the size of the lateral; they are all 

 sub-touching. The second row is a little nearer the first than 

 the third row. The third is as wide as the cephalothorax at 

 that place. The falces are short and vertical, and are about as 

 Avide as long. The maxilla; are more than twice as long as the 

 labium. 



The first leg of the male has the femur and tibia enlarged, 

 the tibia, especially, being thick and long, with a heav}' fringe 

 of hairs on the inner side. 



The abdomen is small, slender and pointed behind. 



The general appearance of Ashtabula is similar to that of 

 Rudra, but Rudra is lower and flatter. It is separated from all 

 the other genera of the group by the curiously enlarged first 

 legs, which seem to make it a connecting link between the 

 Marptusa group and the genus Chirothecia.

 The first leg is enlarged. We cannot get the relative

 The male has the cephalothorax of a bright brown color 

 with a covering of white hairs. These grow thickly at the an- 

 terior part of the eye region, in two bands, which run through,
