Three species onlv of this genus have up to the present been made 

 known fi'om Australia, viz., A. ]<.>n<flpes; L. Koch, .1. )uarulij>e.<, Hogg, and 

 A. n/.-c/j/e>-, Rainb., the first named hailing from Queensland, the second - 

 from Tasmania, and the third from New South Wales. Koch's species was 

 described fi'om a male only, but in 1914 one of the writers of this paper 

 "W.J.R." described that which he took to be the female. Two examples 

 were recorded on that occasion, one being from Eidsvold, and the other 

 from Burnett River, Queensland. The present collection contains another 

 specimen from a locality near Eidsvold. To these nine additional forms 

 are now recorded. 



In elucidation of the species, we submit the following table : — 



Front middle eyes about one half their in^lividual diameter apart (sec. L. 

 Koch) ". A. longipes, L. Koch. 



Front middle eyes one third their individual diameter apart ; thoracic fovea 

 very deep, broad, slightly prociu-ved A. t'uscijies, Eainli. 



Front middle eyes nearly twice their individual diameter apart ; thoracic fovea 



straight, but slightly curved round base of cephahc part 



A. luacuJipes. Hogg. 



Front middle eyes once their iu<li\idual diameter apart, thoracic fovea slightly 



procurved; abdomen marked with broken transverse yellow bars 



A. gi-acilis, sp. nov. 



Front middle eyes alx)ut once their own indi\'idual diameter apart ; thomcic 

 fovea deep, procurved ; abdomen chocolate brown with yellow markings 

 and transverse bars A. festirus, sp. nov. 



Front middle eyes rather small, about once their individual diameter apart ; 

 thoracic fovea procurved ; abdomen ornamented with yellow spots and 

 markings A. similaris, sp. nov. 



Front middle eyes fully once their individual diameter apart ; thoracic fovea 



straight; abdomen chocolate brown marked with yeUow 



.4. pulcheUim, sp. nov. 



Front median eyes three fourths their individual diameter ajiart ; thoracic
