thick and somewhat curved, second subtriangular, third 

 lightly, the following ones more noticeably transverse and 

 somewhat flattened, eleventh somewhat longer than tenth, 

 its tip truncated. Prothorax about as wide as long, sides 

 notched near base ; near base with a conspicuous transverse 

 impression foveate in the middle, with dense subreticulate 

 striation, converging to the sub-basal fovea, but on sides with 

 ordinary striae converging to various depressions. Elytra 

 subelliptic-ovate, greatest width less than twice that of pro- 

 thorax, base truncate and narrowly upturned; with regular 

 rows of distinct and sharply-defined but not very large 

 punctures. Under -surface with dense and sharply-defined, 

 but rather small punctures, larger on metasternum than 

 elsewhere. Legs rather short and stout. Length, 2^-2^ mm. 



Hab. — Queensland: Stewart River, one specimen from 

 a nest of the same host-ant as that of the preceding species, 

 and one from that of a small dark-brown species of Cremas- 

 togaster (W. D. "Dodd). Type, I. 6720. 



Very distinct from all other known species of the genus 

 by its antennae; the joints of these are distinctly eleven in 

 number, but most of them are somewhat flattened, the 

 eleventh being conspicuously wider than thick ; from some 

 directions, however, most of them appear to be moniliform. 

 The sides of the prothorax appear to be notched near the 

 base, rather than gently incurved, and the striae of the 

 upper-surface are not regular ones, but appear to be composed 

 of elongate punctures with bounding walls drawn together 

 in places, so as to be somewhat netlike in character; but this 

 appearance is much less evident from some directions than 

 from others. As on the preceding species, there is no special 

 clothing of the sterna. 



TENEBRIONIBAE. 



Platycilibe brevis, Cart. 



This species occurs in Tasmania as well as on the main- 

 land ; on several specimens (including one from the Blue 

 Mountains sent by Mr. Carter to the late Rev. T. Blackburn) 

 each lateral margin of the pronotum is supplied with a slight 

 projection at the basal fourth, and another and less distinct 

 one at the apical third, and there is sometimes also a still less 

 distinct one nearer the apex ; these appear to be confined to 

 the males. 



Mesotretis inconstans, n. sp. 



Pale reddish-castaneous, appendages somewhat paler. 

 Head with dense and not very large but sharply-defined 

 punctures; with a shallow depression close to each antennary
