$ . Total length 6.8 mm. Width of abdomen 2.4 mm. 



Cephalothorax: length 3; width 3.5; height 1.5. 



Legs 6.1, , 4.9, 6.1; pateUa and tibia of the first, 2.7; patella and tibia 



of the third, 1.9; patella and tibia of the fourth, 2.2: metatarsus and 

 tarsus of the fourth, 2.1. 



Cephalothorax high, convex, a little dilated behind dorsal eyes, with sides 

 rounded more widely behind than in front, cephahc part inclined; 

 thoracic part falling slightly in the first half, and much more steeply 

 in the second. Ocular area occupying nearly one-half the cephalo- 

 thorax, one-third wider than long, wider behind than in front. First 

 row of eyes on a ridge, slightly curved; middle eyes sub-touching; 

 lateral one-half as large as middle eyes, separated from them by 

 nearly one-half their diameter; second row a little nearer lateral than 

 dorsal eyes; dorsal nearly as large as lateral eyes, further from each 

 other than from lateral borders, forming a roTv a httle narroTver than 

 the cephalothorax at that place. Clyi^eus one-fifth as high as middle 

 eyes, vertical. Falces extending to inner edges of lateral eyes, twice 

 as long as face, vertical, parallel; fang short. MaxiUse parallel, di- 

 lated and rounded at extremity. Labium one-half as long as max- 

 illEe, a little longer than wide, contracted and rounded at tip. Ster- 

 num nearly twice as long as wide, a little more contracted behind 

 than in front, narrowest in the middle. Anterior coxee separated by 

 nearly the width of the labium. Legs of the first stoutest, with 

 femoral joints enlarged and compressed. Femoral, tibial and meta- 

 tarsal spines on the four pairs; metatarsi of the fourth spined 

 throughout their length. 



Coloration: Our single specimen of this species being badly injured, we 

 quote the following description from Hentz: 



" Cephalothorax black, with a pale, irregular band each side of the 

 disc; abdomen metallic green, with a band at base, and a diagonal 

 spot each side, orange, and with eight small white spots; underneath 

 obscure gray, with inflections of green on the pectus; feet rufous or 

 pale, varied with piceous 1. 4. 2. 3. This species is related to 

 A. otiosus and mystaceus, but distinct from both by the absence of the 

 tufts of hair on the cephalothorax, and other characters. The palpi 

 are pale yellow, and there is a black band more or less visible on 

 each side of the abdomen," 

 Habitat: Pennsylvania, Alabama.
