few near base of elytra; metasternum, extreme base of 

 abdomen, and intercoxal processes of prosternum and of 

 mesosternum with dense, whitish pubescence; outer apex of 

 each femur with a small patch of greyish clothing. 



Head granulate, and in places deeply strigose. Antennae 

 moderately long, first joint stout and somewhat curved, second 

 slightly longer than third, the following ones moniliform, 

 but eleventh about once and one-half the length of tenth, its 

 tip with sensitized pubescence. Prothorax slightly longer 

 than wide, sides gently rounded, but near base incurved; 

 convex frontal portion with comparatively small punctures 

 and oblique striae, but towards and on the sides with deep 

 striae ; with a narrow and rather deep median line, near 

 base with a rather strong transverse impression, behind and 

 at the sides of which the striae are rather deep. Elytra 

 elliptic-ovate, at their widest about twice the width of pro- 

 thorax ; with regular rows of fairly large, suboblong, sharply- 

 defined punctures, larger at the extreme base than elsewhere, 

 interstices impunctate. Abdomen with not very dense, but 

 almost equally-spaced and moderately large, sharply-defined 

 punctures. Legs rather short. Length, 2-2^ mm. 



Hah. — Northern Territory: Darwin, in nests of 

 Oecophylla smaragdina, and of Rhytidoponera hilli (G. F. 

 Hill). Type, I. 6717. 



About the size of familiaris, but prothorax shorter, the 

 transverse sub-basal impression not quite the same (the 

 depression where it is joined by the median line is deeper 

 than elsewhere, but not foveate), elytra wider and with rows 

 of strongly-impressed punctures. There are also many other 

 slight differences. 



DlPHOBIA FOVEATA, 11. sp. 



, Colour and clothing as described in the preceding species, 

 except that there is no special pubescence on the femora. 



Head with dense punctures, and in places strongly 

 striate. Antennae somewhat longer, but otherwise much as 

 in the preceding species. Prothorax about as long as wide, 

 sides feebly rounded and lightly incurved near base; densely 

 and rather strongly striate throughout, but more deeply on 

 sides, with some punctures in the striae; near base with a 

 strong transverse impression conspicuously foveate in its 

 middle, a smaller marginal fovea on each side, and below this 

 (but invisible from above) another. Elytra much as in the 

 preceding species, except that the punctures are much more 

 numerous and somewhat smaller, although quite sharply 

 defined. Legs rather long. Length, 2 J mm. 



Hah. — Queensland: Townsville (F. P. Dodd). Type,
