I NTRODUCTOR Y REMARKS. 



Ill Part J of this bulletin 1 detailed the habits of sjme Dryi- 

 nidae, and described a large number of species, obtained partly 

 as the results of Mr. Koebele's investigations in 'X. America, 

 and more especially, through our researches in Queensland, 

 from June to December, 1904. 1 now have to record the addi- 

 tional material that Mr. Koebele secured after mv return to 

 Honolulu, when he was continuing- his researches for a few 

 months in New South Wales and Fiji. In my introductory re- 

 'in'arks on the Dryinidae 1 was only able to merely mention a 

 recent paper by Dr. J. J. Kiefifer on these insects, but as this 

 paper throws light on some obscure points, and corrects several 

 errors of older o'bservers, I shall allude to these matters below, 

 as well as making corrections of some clerical errors in my 

 former paper. I also add a full description of that very distinct 

 parasitic fly Pipuiicnhis ciitrichodcs. In Part W of this bulletin 

 this species was omitted in the list of species on p. 131, and no 

 detailed description was given subsequently, but 'both sexes 

 were merely briefly characterized in the "Synopsis of Species" 

 on p. 133 and 135.' 



As the first part of this bulletin dealing with the chief ])art of 

 our material, was altogether without figures, I have now made 

 drawings of many of the important structures therein described. 



GENERAL REMARKS. 



The number of new species of Dryinidae obtained in New 

 South Wales and Fiji was not large, four from the former State, 

 and the same number from the islands; in addition to which 

 I describe two new species from Queensland. It should be 

 mentioned that of the species already described from Bunda- 

 berg. Queensland, which is well outside the tropics, several 

 were afterwards found by Mr. Koebele at Sydney, such species 

 as Paradryiinis kocbclci and Ncodryinus raptor being common 

 there. At Sydney both of these frequently attack Fulgorids of 

 much smaller size than those which are found infested at Bimda- 

 berg. Consequently the Sydney specimens are of very small 

 size as compared with the Queensland examples, but do not 

 otherwise noticeablv differ.
