FAUNA HAWAIIENSIS 



seems hardly more than a flightless form of the apodemic genus Phaenopria, under 

 which I have described species. Probably, however, Hawaiian Phaenopria will prove 

 orenerically distinct from species in other countries. There are nine described species, 

 and doubtless a good many more remain to be discovered. 



The Scelionidae are represented by six species of Anteris, and a single one of 

 Baeus, which belongs to a different sub-family. All are truly endemic, as also may be 

 one at least of the genus Telenoiims, representing yet another sub-family. 



The endemic Cynipoids belong all to the family Figitidae, and to one sub-family 

 of this. Though placed in a number of genera, one of which was described as new, by 

 Ashmead, the rather numerous species that are known appear to me to be all related 

 to one or two types, and probably should be assigned to not more than two or three 

 genera, a view taken by Kieffer without examination of specimens. They present 

 great difficulties in determination, but 23 species have been described without dealing 

 with male examples, which cannot certainly be referred to species of the other sex. 

 I here treat the Hawaiian forms as belonging to only two genera. 



The Mymaridae are represented by 15 species of the genus Polynema, other groups 

 (sub-family and tribes) being unrepresented. 



In the Chalcidoid series the Miscogasteridae have 10 species, placed in four genera 

 and two sub-families, but the characters distinguishing these sub-families are very slight, 

 and I have even had some doubt whether there is any real generic difference between 

 some of the Hawaiian species referred to, the chief genera representing the two 

 sub-families. Some undescribed species are known to me, and doubtless a good many 

 more remain to be discovered. Two of the genera representing the sub-family Lelapinae 

 are endemic. The Encyrtidae is perhaps the most important family of the Chalcid 

 super-family, the sub-family Eupelminae being represented in all by four genera, one 

 of which is supposed to be peculiar {Solindenia). The single Anastattis is clearly 

 imported, being parasitic on eggs of a Locustid, known to have been introduced, nor is 

 it very certain that E2ipelminus, represented also by one species, is really native. 

 Solindenia, the endemic genus (also with only one species), is less liable to suspicion, 

 but not altogether free therefrom, for it certainly occurs, where no endemic host is found 

 for it to parasitize. 



Ejipehnns, on the other hand, contains a large number of endemic species, 54 

 having been described. They are of very varied habits, and as Ashmead recognized 

 but few in the large number of e.xamples that he handled, I fancy he must have 

 lumped together a number of distinct forms. Perhaps I have myself separated them 

 too minutely. 



The Encyrtinae are represented by six species of the genus Anagyrns, which 

 appear to be endemic. This however is uncertain until their habits have been studied, 

 since in other countries the genus attacks Coccidae, and therefore numerous species 

 might easily have been imported with scale insects, accidentally, or perhaps in some
