6-11. 

 Polynema elegans Foerster, Preoc. 



The specific name elegans is preoccupied in Polynema and 

 since Stephanodcs is synonomous with that genus, the name 

 falls. If the species psecas and enockii prove identical, then 

 enockii v^\)X hold. The species is British (England). 



The reasons for considering Stephanodes synonymic with 

 Polynema should be given and are as follows : 



The teeth along the under side of the antennal scape are 

 common to several species of Polynema and seem to gradate 

 in others, without accompanying correlation. Thus in Poly- 

 nema striaticorne Girault they are present and distinctly visi- 

 ble at times, but the proximal funicle joint of the antenna 

 remains short and usual. In Polynema redtivioli Perkins, on 

 the contrary, the unusual long proximal funicle joint of the 

 antenna is present, apparently without the correlating teeth 

 of the scape. Hence the characteristics of Stephanodes lose 

 their value in being too variable and graduate and must be 

 considered as having no more than specific value. There is 

 nothing in the general appearance of Stephanodes to indicate 

 a distinctness from Polyiiema ; in appearance the genus is 

 typically Polynema. I think the foregoing facts are sufficient, 

 in themselves, to establish the identity of the two. The 

 serration of the scape occurs in other genera, it being marked 

 in {Oophilns) Gonatocerus longicauda (Enock), for instance. 



The following notes on extraterritorial species are added : 



Polynema bi*asilieiise Ashm. 



Ashmead, 1904, p. 521. 



From the single female tagmounted, type specimen in the 

 United States National Museum, labelled " Polynema brasiii- 

 ensis Ashm. 9 type" in Ashmead's handwriting, and "Cha- 

 pada, April ", I have taken the following notes : 



Antennse 9-jointed. Second and third funicle joints long and slender, 

 subequal, twice the length of the first and fourth, which are subequal; 

 fifth and sixth subequal, one-third shorter than the fourth or first; 

 club an egg-shaped solid piece, abruptly enlarged and as long as either 

 the second or third funicle joint ; scape short ; pedicel one-third
