tinct from, brocheri Schulz of Europe. In this connection, Perkins 

 has stated: "Anagrus of the Mymaridse attacks the eggs of the 

 Delphacidte alike in Europe, America, Australia, Fiji, and China, 

 and even the species hardly differ in these countries." 



Subgenus PARANAGRUS Perkins. 

 1. Paranagrus perforator Perkins. 



This species was described from Fiji. It was obtained from 

 the eggs of various genera of delphacid leaf-hoppers, usually in 

 grasses, rarely in sugar cane, and was introduced into the Sand- 

 wich Islands in connection with the economic entomology of sugar 

 cane. Its occurrence in .those islands is thus accounted for, but 

 just recently I have captured several specimens of it in North 

 Queensland in an area planted with sugar cane and I have no 

 doubt that its presence here is due to introduction with that 

 plant; more than this, however, it may be the same species as 

 Paranagrus optabilis Perkins described from Queensland, since the 

 two forms are very much alike, and according to Perkins optabilis 

 also occurs in Fiji. The two forms differ only in the presence 

 of an exserted ovipositor in one (perforator) "for a length equal 

 to that of all the joints of one of the hind tarsi taken together." 

 But my Queensland specimens of perforator have the valves of 

 the ovipositor exserted to an extent somewhat less than that 

 described originally. Both specimens are connected with sugar 

 cane. 



Genus POLYNEMA Haliday. 



1. Polynema reduvioli Perkins. 



Of interest generically because of the lengthened proximal joint 

 of the antennal funicle, this species was described from the Sand- 

 wich or Hawaiian Islands, it being parasitic upon leaf-hopper eggs 

 in the leaves of sugar cane. Subsequently, it has been recorded 

 from several islands of the Sandwich group. Mr. Swezey has 

 sent me several specimens of it and I examine them herewith, with 

 special reference to the relations of the species to North American, 

 European and Australian species. As was to be expected, the 

 species is closely related to those species like the type of Stephan- 

 odes Enock, Polynema enockii Girault, Polynema psecas Girault- 

 and the lengthened proximal joint of the antennal funicle is corre- 

 lated in all with the peculiarly broad fore wings bearing very 

 fine discal ciliation and the intense coloration of the yellow part 

 of the body; also the serrated scape. I am the more inclined, 

 since seeing this species, to recognize Enock's Stephanodes with 

 at least the rank of a subgenus, but await, before considering this, 

 the comparison of the three and with an Australian form. I 

 still hold back, also, because of the species bifasciatipenne Girault,
