A New Genus of Chalcidoid hymenoptera of the 

 Family Mymarid/e from TASMANrA. 



By A. A. GiRAULT. 



(Comnmnicated by Mr. A. M. Lea.) 



[Read April 10, 1913.] 



The following genus was found in a collection of parasitic 

 Hymenoptera loaned to me for study by the South Australian 

 Museum. It is the third genus of the family which is peculiar 

 to Australia, so far as is yet known. 



Tribe ANAPHINI. 



PoLYNEMOiDEA, n. gen. 



9 . With the general habitus of Polynema; venation and 

 wings of Cosmocomoidea but the marginal fringes are long; 

 antennae of Folynema but the club is indistinctly 3- jointed ; 

 tarsi 4-jointed, the proximal joint long; abdomen subsessile, 

 no distinct petiole, no phragma, the ovipositor very long and 

 slender, inserted at base and much exserted beyond tip, curved 

 upward ; the exserted portion equals more than the length of 

 the abdomen, which is ovate. Parapsidal furrows complete; 

 scutellum rectangular, wider than long, followed by a still 

 larger, hemispherical mesopostscutellum ; propodium still 

 longer, large. Ocelli in a triangle, the lateral ones rather dis- 

 tant from the eyes. Antennae 11- jointed, the club 3 -jointed, 

 as in Stethynium. Marginal cilia of forewing about two-thirds 

 that wing's greatest width. Forewings fumated, the discal cili- 

 ation moderate; antennae varicoloured. Forelegs with strigils. 

 Scape serrated along its vertical margin. 



^ . Not known. 

 Type. — The following species. 



POLYNEMOIDEA VARICORNIS, n. Sp. 



9 . Length, 1'50 mm. Rather large for the family. 

 Black, the legs yellowish-brown, the first four funicle joints of 

 the antennae white, the antennae otherwise black ; both wings 

 clouded somewhat throughout, but in the forewing this fuma- 

 tion is a stain along the anterior margin, around the apex and 

 broadly across the wing from the marginal and stigmal veins. 

 Forewings with about twenty lines of discal cilia : posterior 

 wings with a paired row along each margin and a short mid- 

 longitudinal line from apex, but sometimes cut off distad.
