resembles in colour, but may be distinguished by the more 

 slender petiole and differences in the distribution of the 

 markings. 



Elimus robustus, sp. n. 



.? . Black ; the mandibles at the base, two oval spots at 

 the base of the clypeus, scape, a spot in the sinus of each 

 eye. a spot on each side behind the eyes, the pronotum, a 

 snot on the mesoplcurse on each side, tegulae, two spots on 

 the posterior margin of scutellum, two obscure marks on 

 median segment behind, petiole of abdomen along the sides 

 and at apex, second abdominal segment at base and a broad 

 band on the apical margin, the legs (with exception of coxa; 

 and trochanters), ferrugineous. Wings pale hyaline, slightly 

 ferrugineous along the costa. 



Clypeus subtriangular. rather broader than long, median 

 segment strongly depressed, a distinct carina along each 

 side, petiole as long as thorax, following segments elongate- 

 ovate. 



Punctured; the head and thorax (except median segment)" 

 coarsely, median segment and abdomen minutely; two 

 carina; converging posteriorly on mesonotum. More or less 

 covered with a pale pubescence, most noticeable on clypeus, 

 vertex, median segment, and the tibia;. 



Length 12^ mm. 



Hab. S. Australia; 2 ? . 



Elimus arabicus, sp. n. 



? . Black ; antenna;, mandibles, clypeus at apex, pronotum, 

 tegulse, the petiole along the sides and beneath, second abdo-

 ferrugineous brown. Tibia; above, narrow band interrupted 

 above in centre on apical margin of petiole, abdominal 

 segments 2-5, pale yellow. 



Wings clear hyaline, slightly fuscous along the costal 

 margin, second abscissa of the radius about £ as long as the 

 third. Clypeus broader than long; thorax massive; petiole 

 as long as thorax, tapering gradually towards apex; second 

 abdominal segment petiolate at base. 



Punctured ; head and thorax coarsely, abdomen more 

 finely, apex of median segment on each side produced to 

 form a sharp up-curved process. Dense grey pubescence on 

 head, thorax (except mesonotum), and abdomen, giving the
