Five New Species Belonging to the Genus Harmolita 



Motschulsky. 



{Isosoma Walker et Auct.) 



BY W. J. PHILLIPS AND F. W. POOS, 

 L'nited States Bureau of Entomology, Charlottesville, Ya. 



THREE of the five species described in this paper (viz., swezeyi, 

 panici and phalaridis) would fall within the genus Harmolita 

 as restricted by Phillips and Emery.- Grahan^ has more recently re- 

 defined the genus, however, and all five of the new species plainly 

 fall within the limits as he has defined them. 



At the time this genus was revised by Phillips and Emery, the 

 senior author had seen only a few specimens of H. cinnce (n. sp. de- 

 scribed herewith), and since the species differed somewhat from the 

 usual type of Harmolita, he did not consider it advisable to broaden 

 the scope of the genus to include this species. Since that time sev- 

 eral similar species have come under observation and they seem to 

 be more closely related to Harmolita than to Eurytoma from a bio- 

 logical standpoint, as well as from the standpoint of external char- 

 acters and the character of the ovipositor. The writers fully agree 

 with Gahan that it is more advisable to include these species in the 

 genus Harmolita than to erect a new genus for their reception. 



The principal characters assigned to the genus by Gahan are as 

 follows: Abdomen of female elongate, conical or subfusiform, with 

 segments more or less subequal, the fourth segment (when prop- 

 odeum is considered a thoracic segment) never greatly enlarged as 

 in Eurytoma. Occiput slightly concave and immargined. Antennae 

 inserted at or above middle of face; flagellum weakly clavate; 



1. Order Hymenoptera, family Eurytomidae.
