RECORDS OF THE AUSTRALIAN MUSEUM. 
Abdomen broadly obovate, strongly arched, slightly projecting 
over base of cephalothorax, very finely pubescent, chrome yellow, 
relieved towards anterior extremity and sides with a series of 
black and dark brown markings, and irregularly shaped large and 
small concolorous spots ; in addition to these there is also present, 
and running down the centre, a delicate net-work of tracery, barely 
visible to the naked eye; the inferior surface is also finely pubes- 
cent, chrome yellow and ornamented down the centre with a series 
of twelve dark brown spots, arranged in pairs, rather widely 
apart, the posterior pair especially so.

Genus Saccodomus,* gen. nov. 
The species for which a new genus is now proposed was first 
brought under my notice some years ago by Mr. W. W. Froggatt, 
who gave me both the specimen and its nest. These have since 
been added to the collection of the Australian Museum. When 
examining it at the time it appeared to me there could be little 
doubt as to the position it should occupy, namely, in the sub-family 
Misumeninse. But, whilst many features appeared to point to this 
sub-family as its correct place, there were nevertheless, some that 
were decidedly conflicting, and these suggested certain important 
analogies with the sub family Stephanopsina\ Indeed, the form 
was so novel, that 1 hesitated to describe it until I could obtain 
more specimens, and devote more time and labour to the elucida- 
tion of the problems presented. 
In my studies I was, happily, assisted by ray esteemed friend, 
Mr. H. R. Hogg, M.A., of Melbourne, who, writing to me upon 
the subject said : — “In this group [i e., Misumenem] it has the 
nearest affinity with the sub-group Diaeeae, and I place it as a new 
genus between Hericeus , E, Simon, and Dima, Thorell, the chief 
points keeping it out of either being : forehead sloping instead of 
vertical ; legs smooth instead of having certain bespinements ; 
rear row of eyes less recurved than front row.” 
During the interval that has elapsed since the above was written 
the subject has been further studied, with the result that both 
Mr. Hogg and myself still incline to the opinion that this species 
should form a new genus to be placed — provisionally — between 
Hericeus and Diem. 
Nevertheless there are yet, to my mind, some very debateable 
points to be removed before the subject can be satisfactorily 
settled, and it may even be necessary hereafter, either to amend 
one of the existing sub-families, or to found a new one for its 
Derivation : wd kko % a bag or purse ; 36pos a dwelling place.
