resident entomologist than of those on a temporary mission, 

 and I do not feel disposed to create a nmnber of new species 

 on males of so-called Labco, when many of these would ulti- 

 mately fall as synonymous with species that 1 have already de- 

 scribed from the other sex. 



Additional material received from Koebele has shown no ex- 

 ception to the general rule that a species of Dryinitl tloes not 

 attack Fulgorid and Jassid indiscriminately. Lahco typlilocybac 

 remains a most peculiar exception*, especially as the female (de- 

 scribed originally as Dryiiuts ormcnidis) of this species, of which 

 1 received some two thousand cocoons, is apparently attached 

 only to certain species of one special group of the Fulgoridae. 

 In my former paper 1 have remarked that the comparatively 

 primitive forms of Dryinidae, having the stigma large and 

 ovate, attack Jassids only. I have now met with a single ex- 

 ception to this rule. At Sydney on January 23rd, 1905, Koe- 

 bele found an adult male of the Fulgorid, Gacfnlia chrysopoidcs, 

 a species frequently attacked in its nymphal condition 'by species 

 of Ncodryinus and Paradryiniis, bearing beneath the body at the 

 insertion of the hind coxae, the black sac of a Dryinid. The 

 sculpture of the sac itself and likewise its position is so similar 

 to that of Ncochclogynus that I can hardly doubt that it belongs 

 to this or some allied genus. L'nfortunately the mature parasite 

 was not bred. 



I may say that the new species here described from Fiji and 

 New South Wales, the fauna in each case being largely distinct 

 from that of Queensland, fall admirably into the genera previ- 

 ously characterized by me. I have some doubts as to the value 

 of my genus Ncodryinus, as, having obtained Latreille's descrip- 

 tion of Dryimis\ I find that this gives 3 joints to the labial palpi 

 like the former, and four teeth to the mandibles. Dryinns, how- 

 ever, as interpreted 'by various hymenopterists. is, in mv opin- 

 ion, a composite genus, and I can not include such forms as 

 Dryinns anicricanus Ashm. and the European D. tarraconcnsis 

 Marshall, which have distinct and paHallel parapsidal furrows, in 

 the same genus as D. ormcnidis, Ashm. and my several species 

 of Ncodryinus, which are without such furrows, because I attach 

 the highest importance to the condition of the parapsides in the 

 classification of the Dryinidae. 



As most of the figures that I have drawn refer to Ft. i of this 

 Bulletin rather than to the present, and necessarily no reference 



* I have now reason to l)elieve that tliis is not a titie cNceiitiuii. on w liicli matter see
