tared, particularly on the petiole. Differs from L. humberti- 

 anus } Sauss., by the coarser puncturation. 



Discoelius, Latr. 

 Discoelius carinatus, sp. n. 



? . Black ; a small spot between the antennae, a band on 

 the apical margin of the petiole dorsally, a broad band on 

 apical § of second abdominal segment, the following segments 

 dorsally, anterior tibiae, ferrugineous red. Head, thorax 

 (especially the median segment) with sparse short grey 

 pubescence. Wings fusco-ferrugineous. Clypeus convex, 

 ovate; mandibles broad; vertex broader than pronotum, 

 wh ch is produced to a sharp point at each angle of the 

 anterior margin ; median segment truncate, slightly concave. 

 Abdomen : the petiole short, the swollen apical portion as 

 broad as long, slightly constricted at the apex, the remaining 

 segments elongate-ovate. 



Punctured ; mandibles and clypeus very coarsely, the 

 head and thorax deeply, sides of median segment striate. 

 Mesonotum with four longitudinal furrows, the two central 

 furrows longer than the others ; scutellum traversed by a 

 longitudinal furrow ; abdomen more finely punctured. 



Length 12 mm.

Strongly resembles D. verreauxi, Sauss., in coloration, but 

 is easily distinguished by much slenderer form of the thorax 

 and the conspicuous row of carinas on the mesonotum, 

 besides which there are differences in the colour-pattern. 

 The length of the thorax serves to distinguish this species 

 from all the described species of this genus from Australia.

Saussure makes no mention of the fact that Elimus has 

 two calcaria on the intermediate tibiae and the tarsal claws 

 bidentate. Both of these characters are applicable to Ischno- 

 cuelia, which appears identical in other respects to Elimus, 

 and thus sinks as a synonym to the older genus. 



Elimus ferrugineus, sp. n.

 scape beneath), mandihles, a spot in the sinus of each eye,
