138 RECORDS OF THE AUSTRALIAN MUSEUM. 



D. subrufus, L. K., there is a note to the effect that specimens 

 had been taken at Bowen and Brisbane, and were then in the 

 Godeffroy Museum ; there was also an example from Boude 

 [? Bondi] in Mr. Bradley's collection, which that gentleman had 

 found on the 3rd of June running about amongst grass. ^ D. 

 ravidus, L. K., was taken by Herr Daemel, under dry leaves, at 

 Gayndah f D. Jasciatus, L. K., was collected by him at Bowen 

 and Gayndah, under leaves ;^ D. bicornis, L. K., was described 

 from a male example collected by Mr. Bradley, at Sydney, where 

 it had been found living amongst the grass, but there was no web.® 

 Doleschall records, briefly, a species of Diyiopsis, in Amboina, 

 that constructs a large, irregular snare, in the centre of which it 

 rests, with its anterior feet extended in a line with its body.® 



The second sub-family, Uloborinfe, also includes only two 

 genera, namely, Uloboms, Latr., and Sybota, E. Sim. The 

 latter does not occur in Australia. Uloborus is distributed as 

 follows: — "Europa et Regio mediterranea; Africa; ins. Atlanticse; 

 Madagascar ; Asia, centr., merid. et orient ; Malaisia ; Papuasia 

 et Oceania; America septr., centr., merid. et antilliana."" 



Five species of Uloborus have been recorded from Australia, 

 namely, U. barbipes, L. K., from Port Mackay ; U. canus, Macl., 

 collected during King's survey of the intertropical and western 

 coast of Australia, but no specific locality given ; U. variabilis. 

 Keys., Rockhampton, Peak Downs, Gayndah, and Sydney; U. 

 spinitarsis, Keys., Sydney ; and U. paniherimus, Keys., Sydney. 



The webs of Uloborus are obicular, and are usually spread 

 horizontally. They consist of rays and concentric circles, the 

 meshes being supported and strengthened by numerous outer 

 lines or guys, the latter being directed in an irregular manner, 

 and at every conceivable angle. The spiders of this genus are 

 mostly small, and so are their webs. The number of rays and 

 concentric rings, as far as I have been able to gather from obser- 

 vation of Uloborid snares around Sydney, vary slightly. Usually 

 there are twenty-four of the former and fourteen of the latter, 

 sometimes more and sometimes less. The silk employed in the 

 construction of the outer lines and rays is discharged from the 

 mammiform spinnerets, and is tough and strong ; that of which 

 the spirals is composed is voided by the cribellum, and carded by 

 the calamistrum, and is soft, dry, and flocculent. In this respect 

 the spirals of an Uloborid web differ widely from those constructed
