Ohs. — Several matured examples collected by one of us [H.H.P.]. 

 Very like A. ijraciJis {ante p. 110), by its abdominal ornamentation, but 

 it may be easily distinguished therefrom by its larger size and bi'oader 

 eye place. The entrance to the burrow is ]>rotected by a thick lid. The 

 ova-sac is elliptical, composed of a tliin white silken tissue, and is tough 

 and strong. Ft is 24"5 mm. long, and 18 mm. Avide.
