NOTES ON THE FAMILY BRACHYSCELID.E, WITH 

 DESCRIPTIONS OF NEW SPECIES. 



Part II. 



By Walter W. Froggatt, Technological Museum, Sydney. 



(Plate vin.) 



The second part of my Notes on this group contains descriptions 

 of gall-making coccids belonging to the genera Ojnsthoscelis and 

 Ascelis, which were formed by H. L. Schrader in his second paper 

 entitled "Further Communications on the Gall-making Coccidse," 

 published in the Proceedings of the Entomological Society of New 

 South Wales, Vol. i. p. 6 (1862). 



These genera he defined as follows : " Ojnsthoscelis where they 

 have only two long posterior legs" ; and ^'Ascelis where there are 

 no vestiges of legs." 



I have examined a large amount of material and have come to 

 the conclusion that Ojnsthoscelis subrotunda, Schrader, the type of 

 the genus, is a very distinct species ; but 0. gracilis^ in my 

 opinion, is only a variety of it. 



Not having all my notes on a number of other species of this 

 genus quite ready, I hold them over for Part III., so that in the 

 meantime I can examine several in their later stages of development. 



I have had some correspondence on the characteristics of these 

 coccids with Mr. W. H, Maskell, who says that "The Group 

 Brachyscelidce should be confined to those coccids in which the 

 female has the last segment produced into 'a tail,' and that the 

 fact of producing a gall alone does not constitute a Brachyscelid." 

 Acting on the advice of such a well known authority on the 

 Coccidce, I at present confine my observations to the coccids that 

 can be placed in the above genera, considering that the peg-like 

 anal projection of Opisthoscelis subrotunda, Schrader, and the more 

 rounded tails of other " spine-gall "-making species, as well as the 

 remarkable tubular appendage of Ascelis (though it is doubtful on
