A NEW GALL-INHABITING EULOPHID GENUS FROM 

 QUEENSLAND, AUSTRALIA. 



By a. a. Girault. 



HYMENOPTERA CHALCIDOIDEA. 



Family Eulophid^. 



Subfamily Elachertin^. 



Tribe Elachertini. 



Zagrammosomoides, new genus. 



i^cwa/c— With all of the characters of its subfamily and tribe as 



defined by Ashmead in 1904. 



Allied with and resembling Zagrammosoma, Ashmead, but more 

 robust, the wings hyaline, the head not thin, not wider than long but 

 triangular, the scutellum with four longitudinal grooved lines, the 

 antennse ten-jointed with two-ring joints, the abdomen transversely 

 banded. Separated from the other genera in bearing an additional 

 ring-joint in the antennae, the longitudinal thoracic grooves and m 

 cephahc characters. The thorax is noteworthy because of the very 

 long scutum, which is twice the length of the scutellum, the latter 

 bearing two longitudinal grooved Hues along each side. Mesonotum 

 without a median groove. The abdomen is stout, sessile, ovate, sub- 

 equal in length to the head and thorax combined, the ovipositor not 

 exserted. The fore wings are large, with a short marginal fringe and 

 normal discal ciliation, the postmarginal vein only shghtly developed 

 but distinct, the stigmal vein two and a half times longer, the mar- 

 ginal longer than the submarginal. The antenna has a well-defined 

 club which is ovate and three-jointed, the three funicle joints are 

 each much smaller than the pedicel and subquadrate ; scape long and 

 stout. The pronotum lengthens considerably on each side. Genal 

 sulcus long and distinct. Antennas inserted on a Hne with the ventral 

 ends of the eyes. Metathoracic spiracle oval, moderate in size. Pro- 

 podeum with a short, slight, median carina, but with no others. 

 Mandibles three-dentate, the two outer teeth acute. 



il/a/e.— The same, but the pedicel is a httle longer, the club 

 shorter, the abdomen shorter and depressed (in death), the same, or 

 nearly, but in life a little less acute at the apex. 

 Type. — The following species.
