the middle eves. The middle eyes are nearly twice as lar2:e as 

 the lateral. The second row is plainly nearer the first than the 

 third. In the male the falces are strong and projecting, with 

 a long fang, in cyanidens and funehris, but vertical in griseus. 

 In both males and females, so far as we know them, the first leg 

 is plainly the longest, and the fourth next. 



This genus has for its type Phidippus cyanidens C. K., which 

 we have from Texas, Mexico, Guatemala and Brazil. To this 

 we add Phidippus funehris Banks, (Arachnida frotn Baja Cal- 

 ifornia, and other parts of 2Iexico), from Vera Cruz. 



Parnaenus? griseus, sp. nov. 



PI. XXVT, figs. T-Tb. 



Large spiders, black below and silvery gray above. 



0. Length, 11.5 mm. Legs, 1423, first stoutest. The first 

 is longer than the second by the metatarsus and tarsus. The 

 second and third differ but little. The fourth is longer than the 

 third bv the tarsus and half the metatarsus. 



The cephalothorax, which is not much longer than wide, is 

 highest behind the dorsal eyes. The quadrangle of the eyes is 

 one-fourth wider than long, is plainly wider behind_than in 

 front, and occupies scarcely two-fifths of the cephalothorax. 

 The palpi are stout. The maxillae are widened at the end, with 

 a projection at the outer corner. The falces are stout, vertical, 

 and not iridescent. The cej^halothorax and abdomen are cov- 

 ered, above, with silvery iiray hairs, which reach, on the sides 

 of the cephalothorax to a little below the eyes. The lower sides of 

 both cephalothorax and abdomen are black. There are long 

 bro^\^l and ^^nhite hairs scattered over the whole body. The legs 

 are black, excepting the proximal halves of the tarsi, -Ahich are 

 light colored with white hairs. There is a short thick fringe 

 under the first leg, which is w^hite on the patella and black on the 

 tibia. The palpus has white scale-like hairs, and also long 

 white hairs, on all the joints. With some hesitation, we place 

 this species in the genus Parnaenus. The widest pai*t of the 

 cephalothorax is just behind the dorsal eyes, not so far back as 

 is represented in the figure. 



We have one male from Las Cruces, ^N'ew Mexico.
