truncate behind, sinuate near the external angles which are 

 moderately produced ; the sides provided with setae. Abdomen 

 narrowed behind, with lateral setae. Legs rather short ; intermediate 

 coxa3 near together ; tarsi 4:5:5. 



This genus is founded on two species found in ants' nests in 

 West Australia and is allied to the European genus Dinarda the 

 species of which are found in similar situations. It may be dis- 

 tinguished by its more attenuated setose body ; more strongly 

 produced head ; and by certain differences in the comparative 

 lengths of the joints of the antennae and maxillary palpi, particu- 

 larly the enlarged basal joint of the former and the elongate third 

 articulation of the latter.

 (Plate VII., fig. 2.) 



Elongate, moderately convex, ferruginous, somewhat shining, 

 finely and very closely punctured, very finely pubescent, the sides 

 strongly setose ; antennae with joints 4-10 dark ferruginous. 



Head broadly transverse, finely and closely punctured. Antennae 

 with the first three and the apical joints testaceous, the latter as 

 long as the three preceding joints together. Prothorax at the 

 base about twice as broad as long, arcuately narrowed in front, 

 decidedly convex on the disc, flattened laterally, very finely and 

 closely punctured ; the anterior angles obtuse ; the sides furnished 

 with seven or eight erect setae ; the posterior angles moderately 

 produced. Elytra at the base slightly narrower than the prothorax, 

 somewhat broader posteriorly, finely and very closely punctured ; 

 the sides slightly reflexed and furnished with three or four erect 

 setae ; posterior margin rather deeply sinuate just before the 

 external angles which are moderately strongly produced. Abdo- 

 men moderately narrowed behind, extremely finely and not very 

 closely punctured ; each segment with two or three lateral setae ; 

 segments 2-5 with a row of fine setigerous punctures on the
