the space between the coxae of the two sides equal to J the body-width. 

 Tarsi with a thick dorsal protuberance distally. 



Description based on two specimens found beneath rocks in dry 

 places at Lima, Peru, by Gaudichaud (Paris Museum). 



This species is doubtfully distinct from A. reflexus. Neumann 

 thought it might be the male of A. magnus, which he has since fused 

 with A. reflexus (see p. 22).

Resembling A. reflexus, but differing from it as follows : 



Adults : Body short oval, and almost as broad in front as behind. 

 Margin striate like that of reflexus, but relatively broad (3 mm.). 

 Spiracles scarcely as long as the width of the anus. Sexual orifice of 

 the male very small, facing the posterior extremity of coxa I. Capitulum 

 very small ('8 mm.) and very posterior, far from coxae I, lying in a 

 clearly marked camerostome. Hypostome narrow, palps short. Coxa I 

 far from coxa II, and the space between the coxae on the two sides 

 very broad — equal to one-third the width of the venter. Tarsi I much 

 humped distally, the protuberances on the other tarsi slight.
