 punctures, of which the median one is distinctly nearer the subapical 

 than the subbasal one; disc feebly transversely wrinkled, and with a 

 setiferou.s puncture on each side ; with small punctures scattered aliout,

 subtrianfjular, with moderately dense punctures. Elytra at base 

 -vider than widest part of elytra ; sides fjently rounded and dilated 

 to bevond the middle ; with distinct but not deeply impressed striae, 

 the interstices of somewhat uneven widths, and with dense clearly 

 defined punctures, third with four larger setiferous punctures, ninth 

 (the marginfil interstice) with an almost regular row of larger punc- 

 tures. Fygidiuiii with dense but somewhat inegular punctures.

In size and appearance unuh like (piiulri pctmU and Siidiicii(')i><i>i, 

 but prothorax with emargination of apex more even, and basal angles 

 completely rounded off. 



On each elytron, the vitta at the luise is ciuifined to the fifth inter- 

 stice ; it immediately dilates so as to include the fourth, at about the 

 basal third it extends to part of the third and sixth, at about the 

 middle it occupies only the third and fourth, and it then contracts 

 so that at its apex it is only on part of the third. 



Although not desci-ibed, a specimen of this species was previously 

 noted (these Proceedings, 1910. p. 122) as having Ijeen taken from 

 an ant nest ; as since then I have taken another specimen in the 

 same way, it is to be presumed that the species naturally occurs with 

 ants.

On sending a specimen of 'this species from Geelong Mr. Dave}' 

 wrote: — "Recently I opeiie<l an old established nest of Iridomyrmea- 

 iiifidus, and it contained a fair nmuber of this species; they Avere 

 quite covei-ed V)y the ants, ])ut they did not appear to be eating them.''
