Rev. F. D. Morice's Notes on Australian Sawflies. 299 



In the $ of caudata, which is very nearly as large as the 

 9 (about 4 mm.) the abdomen is unicolorous, blackish 

 from base to apex, the antennae 11-jointed. 



The other <$<$ had better, I think, remain undetermined 

 in the absence of any 99 with, which they seem likely to 

 be associated. It will probably be found that several 

 species (or at least subspecies) exist in Tasmania and else- 

 where. The Type of metallica is not from Tasmania, but 

 from Victoria. 



CLARISSA, NEWMAN. 



SYNOPSIS OF THE SPECIES. 



Though the relationship between Clarissa and Eurys is 

 evidently very close, they differ so markedly — at least in 

 the few species of each yet known to me — in the matter 

 of coloration, that it is easy to distinguish them at sight. 

 In Eurys this coloration is thoroughly metallic — as much 

 so as in many of the Chrysididae, whereas in Clarissa it 

 requires close examination to discover any tendency to 

 metallescence. The present metropolis of Eurys seems to 

 be West Australia, while that of Clarissa seems to be 

 rather North Queensland, and the only locality I can name 

 where both genera have yet occurred is the neighbourhood 

 of Adelaide. Striking as is this difference in colour, it is 

 perhaps of no very essential importance, for in many 

 Hymenopterous and other genera metallic and also non- 

 metallic species occur in the same regions. Still, as they 

 differ (though slightly) in neuration, and on an average in 

 the number of antennal joints, the distinction between 

 them may provisionally be treated as generic : yet it 

 would not be surprising, if the discovery of intermediate 

 forms should lead to a uniting of them at some future 

 time. But setting aside this possibility, which it is really 

 useless to suggest while so few of the imagines and none 

 of the larvae, etc., of either genus have been described, I 

 will proceed to a tabulation of such material as lies before 

 me.
