tends from the anterior lateral eye to the posterior border; the mid- 

 dle band has its origin on the upper surface of the caput and passing 

 down between the middle and lateral eye of the first row curves 

 backward and extends along the side of the cephalothorax through 

 about half its length; the lowest of the bands is the narrowest; it 

 begins oi)posite the origin of the palpus, and passes backward just 

 above the lower border, terminating a little beyond the middle band. 

 A wide vertical white band passes between the anterior middle eyes 

 from the upper surface of the caput to the origin of the falces. Ab- 

 domen bronze brown, nearly encii'cled by a white band which ex- 

 tends around the base and sides and ends abruptly just above and in 

 front of the spinnerets. Clypeus, falces, mouthparts and sternum 

 brown; venter brown with three white bands, one on each side, and 

 one connecting these at the apex. 

 $ . Cephalothorax brown with short white hairs. Abdomen very vari- 

 able; sometimes pinkish with white bands at base and on the sides, 

 and four pairs of white spots; sometimes brown with many pale 

 spots and curved bands; sometimes brown with four pairs of black 

 spots (resembling E. oetavus) ; sometimes bronze with white hairs at 

 base and on the sides, and two longitudinal black bands upon which 

 are three or four pairs of white dots (resembling P. militaris). Cly- 

 peus white. Other parts varying between light and dark brown. 

 This species is much like P. militaris, but is easUy distinguished from it 

 by the difference in size, P. militaris being considerably larger. The male 

 sometimes retains the markings of the female, these being j^roper to it in 

 the immature stage. It was a male of this kind that we described as new 

 under the name of A. cestivalis. 

 Habitat : United States. Mexico.
