FAUNA HAWAIIENSIS 



long series of sufficiently variable forms (such as Phytocoris populi, Calocoris seticornis, 

 Lygus pratensis or Cyllccoi'is liistrioiiiciis in Europe ; Natrocolpus mcbilus or Poecilo- 

 capsus bneattis in America) would effect a pronounced change in the attitude of many 

 workers towards the limits of specific differences. 



Of the 76 species and named varieties definitely acknowledged', 68 are, so far as is 

 known, precinctive ; that is to say 89'5 per cent."

These figures are, unfortunately, not quite accurate, as I have had to omit Rcclada 

 moesta, Clcrada apicicornis, Merragata kebroidcs, Eysarcoris instilaris, Btichananiella 

 sodalis, and Klinophilos IcctuiariHs, of which there are no distributional particulars ; 

 three of these are precinctive, three extra-Hawaiian. The high percentage of Kauai is 

 very natural, that of Oahu is probably to be explained by the fact that it is the principal 

 island for commerce and that the early records of three species were noted as ' Oahu ' 

 or ' Honolulu,' but not necessarily actually from them. 



The following Tables will show at a glance the intra- and extra-Hawaiian distribution 

 of the species now described or noted, the Coccidae and Nysins being omitted. 



Coccidae (since they are all, probably, accidental recent importations), Halobates, Nysiiis, spp., 

 Bythoscopus peregrinus and vidmis, and Tetigonia varicolor, the Jassinae and Asiracinae are omitted from these 

 considerations. Eysarcoris insularis, Anisops sp., and Rhopalus sp., are also omitted. Zelus peregrinus is 

 counted as non-precinctive. 



If we include 16 spp. oi Nysius, Halobates, Bytlioscopus peregrinus and vidiiiis, Tetigonia varicolor a.nd 

 Eysarcoris insularis, and take Zelus peregrinus as precinctive, we obtain 97 species of which 89 are precinctive, 

 that is 91 '8 per cent. !
