In general appearance close to the preceding species, and 

 with very similar elytra, except that the seriate punctures are 

 much closer together, but antennae slightly and legs decidedly 

 longer, striation of the prothorax denser, more deeply 

 impressed, and the sub-basal excavation considerably larger 

 and decidedly foveate in character, the abdominal punctures 

 are also smaller, and the femora are without special clothing. 

 The eyes in both are prominent and pointed. 



DlPHOBIA METALLICA, n. Sp. 



Black; elytra dark metallic-blue or green. Clothed with 

 rather short and erect or suberect greyish setae, not very 

 dense but quite conspicuous. 



Head with dense punctures and in places deeply striate. 

 Eyes rather pointed. Antennae rather long, first joint stout 

 and somewhat curved, second slightly shorter than third, the 

 following one moniliform, but eleventh about once and one- 

 half the length of tenth, and with its tip obliquely truncated. 

 Prothorax slightly longer than wide, sides gently rounded, 

 near base gently incurved, near base with a conspicuous trans- 

 verse impression and (concealed from above) with a fairly 

 large fovea on each side; with dense, sharply-defined striae, 

 all (except those on sides) converging to the middle of the 

 sub-basal depression, but the depression not foveate there. 

 Elytra strongly convex, elliptic-ovate, at widest about twice 

 the width of prothorax ; with semi-regular rows of distinct 

 but not very large punctures, not very close together. Under- 

 surface with fairly numerous, sharply-defined punctures, 

 larger and denser on metasternum than elsewhere. Legs 

 moderately long. Length, 2-2 J mm. 



Hab. — Queensland: Stewart River, nine specimens from 

 nests of Iridomyrmex, either a variety of detectus, or close to 

 that species (W. D. Dodd). Type, I. 6719. 



Readily distinguished from all other known species of 

 the genus by its metallic-blue (or green) elytra, with distinct 

 clothing. On two of the specimens the appendages and 

 abdomen are vaguely diluted with red, but on all the others 

 they are deep black. The elytral setae are in quite regular 

 lines, as may be seen on examining them from the rear ; there 

 is no special clothing on the sterna, as on so many myrme- 

 cophilous species of the family. 



DlPHOBIA INTRICATA, U. Sp. 



Dark blackish-brown, appendages somewhat paler. 

 Prothorax and base of elytra with a few very short, erect, 

 dark setae. 



Head with dense punctures, and in places punctate- 

 striate. Eyes acutely ridged. Antennae stout, first joint
