A NEW MYMARID GENUS AND SPECIES FROM NORTH 

 AMERICA ALLIED WITH ANTHEMUS HOWARD. 



BY A. A. GIRAULT. 



The genus Anthemns Howard of the chalcidoid family 

 Mymaridae is represented thus far by but a single species 

 which occurs in Ceylon. This species has never been retaken 

 since its original description, and so far as I have been able to 

 ascertain from the literature no other representative of the 

 genus has ever been recorded or described. It is pleasing to 

 me, therefore, to be able to describe the following allied North 

 American species which I captured from the glass sides of a 

 greenhouse on the campus of the University of Illinois, but 

 which I think must be considered as typical of a new segre- 

 gate of subgeneric or generic rank. This capture was made 

 so casually that it goes far to show that our fauna as repre- 

 sented by the Mymaridse must still be largely unknown and 

 that a serious study of the group as it occurs in North America 

 will still be amply rewarded. 



FAMILY MYMARIM}. 

 Subfamily MYMARIN^E. 



Tribe ANAPHINI. 

 ANTHEMIELLA, new genus. 



The type species is described first, then the generic diag- 

 nosis given. 

 Normal position. 



1. Anthemiella rex, new species. 



Female. Length, 0.50 mm. Minute but visible to unaided eye. 



General color sooty black, marked with golden yellow as follows: 

 The proximal half of the abdomen, margins of the eyes narrowly 

 (lateral aspect), and a portion of the mesonotum caudad of the inser- 

 tions of the cephalic wings (the mesoscutellum) to the metathorax. 

 Thus, the body is black with a portion of the dorsal aspect of the 

 mesonotum and the basal half of the abdomen contrasting and golden 

 yellow. Legs dusky or smoky, nearly concolorous with the general 

 body color, excepting the trochanters, knees, and tips of all tibiae, 

 which are yellowish; tarsi dusky, but the two intermediate joints 

 somewhat lighter. Antennae concolorous with the legs, the club and 

 scape darker. Eyes ruby red. Fore wings hyaline, but their basal 

 fourth distinctly fumated (out nearly to the end of the venation, the 

 distal margin of the fumation concave). Venation dusky yellowish. 

 Caudal wings lightly splotched with dusky.
