Family ARGIOPID^E. 



Mr. W. Bullock, of the Parkville Public School, near Scone, 

 New South Wales, has from time to time presented to the 

 Trustees many interesting forms both of Spider and Insect life. 

 Amongst his recent donations were two species of Araneidaj, and 

 as these appear to be new, they are described hereunder. The 

 first of these is an Argiope, Aud. in Saw, for which I propose 

 the name A. bullockii, and the second a species of Celcsnia, Thor., 

 for which the name C. calotoides is proposed. The first of these 

 specific names is in honour of the collector, and the second is 

 applied on account of the remarkable resemblance borne by the 

 cocoons or ova-sacs to the fruiting heads of Calotis, R.Br., 

 especially G. lappulacea, Benth. I am indebted to Mr. J. H. 

 Maiden, Director of the Botanic Gardens, for his courtesy in 

 examining the cocoons, and comparing them with the fruiting 

 heads of the plants referred to above. 



In reference to C. calotoides, I would like to point out that 

 some time ago Mr. Bullock forwarded to the Museum a series of 

 these peculiarly burr-like egg-bags, but without the spider. The 

 egg-bags were new to me, but on examining them I concluded 

 they were the work of a species of Celcenia. Accordingly 1 sent 

 Mr. Bullock some sketches and notes of C. distincta, Cambr., 

 asking him at the same time to keep a sharp look out, when 

 collecting, for the maker of the cocoons. In this respect my 

 correspondent was ultimately successful, securing three specimens, 

 each of which had a series of cocoons. One of these Mr. Bullock 

 retained for his own collection, but the other two are now in our 

 cabinets. 



Writing to me upon the subject of C. calotoides and its cocoons, 

 .Mr. Bullock observed : — "I had had a ramble in the bush, and 

 had collected a number of spiders, and was on my way home
