300 HYMENOPTERA. 



genus from West Australia which is new and will be de- 

 scribed elsewhere. Also, later I found a single male speci- 

 men of faunum in my personal collection mounted with miscel- 

 laneous mymarids {Polynema howardii ; Gonatoceous brunneus 

 and so forth) captured by sweeping low vegetation at Ur- 

 bana, Illinois, May 25, 1910. The antennae are filiform and 

 13-jointed, the flagellar points longitudinally striated, the 

 joints subequal and gradually lengthening distad, excepting 

 the proximal joint which is shorter nearly by a half than the 

 second funicle joint, longer than wide, slightly longer than 

 the pedicel which is globular. The twelfth and thirteenth 

 joints forming a rather long club, the distal joint shorter. 

 The funicle joints are acute at their disto-lateral margins. 

 Otherwise as in the female, excepting that the abdomen is 

 shorter and more blunt. 



Tribe Mymarini. 

 Genus EUSTOCHUS Haliday. 

 1. Eustoclius xanthotliorax Ashmead. 

 Ashmead, 1887, pp. 193-194. 



As stated above this is Anagrus armatus (Ashmead). The 

 original specimen was in bad condition, a soiled female 

 specimen, the body evidently wholly yellow, not as de- 

 scribed ; the tarsi 4-jointed, the abdomen sessile, not petio- 

 late, hence it can not be an Eustochus ; the original specimen 

 was labelled in the handwriting of Ashmead, ''Eustochus 

 xanthotliorax Ashm. Type." and "Jacksonville, Fla." on a 

 printed label. No number was in connection with it. It 

 agrees perfectly with Anagrus armatus Ashmead. No spe- 

 cies of this genus have been found to occur in North America 

 up to the present time. 



Genus POLYNEMA Haliday. 

 1. Polynema howardii (Ashmead), 



Cosmocotna elegans Howard, 1881, p. 371, pi. xxiv, fig. 7. 

 Cosnioconia howardii Ashmead, 1887, p. 194. 

 Idem, de Dalla Torre, 1890, p. 97. 

 This species was lost and nearly unrecognizable from its 

 description and its identity in collections has been consider- 

 ably mixed. It will be a difficult species to recognize with-
