Cephalothorax high; thoracic part a little dilated, a third, or only a quar- 

 ter (A. saltator) the longer. Cephalic part plane or a little convex, 

 inclined forward, limited by a slight depression which is straight or 

 slightly bent.' 



C Jypevs equal to half the large middle eyes, or a little narrower, rarely 

 wider {A, floricola $ ). 



Eyes of the face rather unequal, a little separated, at least the lateral, and 

 usually in a slightly curved line; dorsal eyes usually a little smaller 

 than the lateral, as far or a little further apart; quadrangle scarcely 

 a third wider tnan long; dorsal eyes equally far or a little further 

 from each other than from the lateral borders. 



Sternwm elongated, as narrow as the intermediate coxae (except A. attel- 

 lanus S ). 



Falces weak, vertical, as long or shorter than the face. 



P aJpus normal. 



Legs 4, 1, 2, 3, rarely 1, 4, 2, 3; remarkable for the pre-eminence of the sec- 

 ond pair over the third. Tibia and patella of the first as long {A. 

 Wagce, frigidus) or most often shorter than the cephalothorax; ($ ) 

 these two articulations equal; ( 6 ) tibia longer; tarsus and metatar- 

 sus more slender (except A. cingulatus) and shorter (often barely) 

 than the two preceding articulations. Fourth legs much longer 

 than the third in all their articulations, principally the femur and 

 the tibia; tibia at least a third longer than the patella, slightly en- 

 larged from the base to the extremity and .a little compressed; tar- 

 sus and metatarsus of the fourth much shorter than the patella and 

 tibia (except some males: A. floricola, etc.). Femoral, tibial and 

 metatarsal spines on the four pairs and throughout the length of the 

 t.rticulations.
