ISOPEDA DOLOSA L. Kocll. 



YoGonia dolosa L. Koch, Arach. Austr. 1875, p. 648. 



L. Koch described this species from two dried specimens in 

 the Museum at Stuttgart, labelled "Australia" only. The differ- 

 ences by which he says it may be distinguished from /. insignia 

 Thor., are that " the clearly smaller median eyes of the front row 

 are more than their diameter from the rear median," and the 

 joining by a dark longitudinal marking of the two median pair 

 of muscle-spots on the back. The latter feature seems a by no 

 means uncommon variation in any species, whenever the back spots 

 9,re specially well developed, and the former is almost universally 

 the case with females of /. insignis Thor. I have therefore great 

 doubts as to it being really a separate s]3ecies ; if it is, the joining 

 of the back spots is its only distinctive character. The Horn 

 Expedition had several specimens from Central Australia, both 

 male and female, with back-markings as described, veiy flat 

 cephalothoi'ax, but front row of eyes equal, and I have similar 

 from Victoria, otherwise the same as /. insignis. 



ISOPEDA SUBDOLA Thor. 



Holconia suhdola Thorell, Rag. Mai. e Pap. vol. iii. 1881, 

 p. 304. 



Thorell himself describes this as a doubtful species, the only 

 difference from Koch's description of H. dolosa being in the 

 coloration of the back of the abdomen.
