EDUSA. 



The following species while certainly, I think, a member of the 



group Edusites, differs from typical members of the genus Edusa 



by its unusually narrow parallel form and its entirely glabrous 



upper surface. Five Edusoid genera have been recorded as 



Australian, viz., Edusa, Edusoides, Clepter, Thauma stonier us and 



Ocnida. The insect before me certainly cannot be attributed to 



the second or third of those genera, — but the last two do not 



appear to me to have been satisfactorily differentiated from 



Edusa. Thaumastomerus was unknown to Dr. Chapuis (as it is 



to me) and he conjectured that it ought not to be separated from 



Edusa. Of Ocnida he says that its diagnosis does not contain 



any tangible character for identification, — in whick opinion I 



agree with him. The following species is not any of those that 



have been attributed to those genera, and so far as I can make 



anything of the generic diagnoses it does not agree with them, 



nor can I find any marked structural character inconsistent with 



its place in Edusa which (as Dr. Chapius conceived it) included 



forms widely differing in superficial characters. 



E. angustula, sp. nov. Sat angusta, sat parallel a ; supra glabra; 



subtus pilis erectis brevibus gracilibus sparsim vestita ; 



metallico-versicolora (viridis, aureo cupreoque varie micans), 



antennis (his apicem versus infuscatis) palpis labro pedi- 



busque testaceis ; capite verticali, sparsius subtilius punc- 



tulato ; antennis filiformibus apicem versus parum incras- 



satis, quam corporis dimidium parum longioribus ; prothorace 



leviter transverso, ut caput (latera versus magis crebre) 



punctulato, antice modice angustato, lateribus arcuatis, 



angulis anticis obtusis nullo modo productis, posticis obtusis 



(his, in prosterno visis, dentif ormibus) ; elytris crebre punc- 



tulatis, apicem versus nonnihil punctulato-striatis, totis 



fortiter rugatis ; femoribus (sexus observati) haud dentatis 



sed subtus late subangulatim dilatatis. Long., 2 1.: lat., 4 1. 



In my tabulation of the species of Edusa (Tr. R.S., S.A., 1891, 



pp. 142-3) this insect falls beside glabra (at the end of the table) 



from which it may be thus distinguished : — 



C. Form widely oval ... ... ... ... glabra, Blackb. 



CC. Form narrowly parallel ... ... ... angustula, Blackb. 



I have seen four examples of this species, among which I find 

 no conspicuous sexual differences. Probably they are all females.
