434 STUDIES IX AUSTRALIAN ENTOMOLOGY, 



Ventral segments transversely sulcata ; ^ with apical segment 

 deeply bifoveolate towards middle. 



It seems impossible to associate the species on which this genus 

 is founded (S. punctiventris ) with any previously described Aus- 

 tralian Feronide. Having only one specimen, and that with the 

 maxillary palps and the apical portion of the antennae wanting, 

 I am unable to diagnose the genus fully ; but the characters 

 given alcove distinctly separate it from the many divisions that 

 have been formed among the Feronides of Australia. As far as 

 I know, Setalis niger, Casteln., is the only other Australian 

 Feronide with the last ventral segment deeply bifoveolate ; this 

 character I believe to be a sexual one, but never having seen the 

 female of either of these species, only judge by analogy from the 

 Chljeniide genus Coptocarjnis, in which it also occurs, Ijut only in 

 the male. 



SeTALIMORPHUS PUNCTIVENTRIS, n.Sp. 



Elongate-oval ; head smooth ; prothorax suljquadrate ; elytra 

 striate, the interstices convex, third unipunctate. 



(J. Black ; undersurface, legs, antennae and mouth-parts reddish- 

 piceous. Head small, suddenly constricted to a wide neck behind 

 eyes ; front strongly impressed on each side ; the impressions 

 wide apart, diverging backwards ; eyes globose, very prominent, 

 enclosed behind ; an obsolete transverse impression across vertex 

 level with posterior margin of eyes. Prothorax subquadrate 

 (2-2 X 2-4 mm.), widest a little before middle, rather depressed, 

 declivous on each side to anterior angles ; sides lightly rounded 

 on anterior half, a little narrowed to base ; anterior angles wide, 

 lightly marked, not advanced ; base subtruncate, widely and 

 lightly emarginate across peduncle ; basal angles rectangular ; 

 lateral border narrow, I'eflexed, ending behind at basal angles ; 

 median line distinctly impressed ; two basal impressions on each 

 side, the interior strongly impressed, narrow, placed aljout half- 

 way between median line and margin, the other lightly marked, 

 wide, short, near basal angle. Elytra a little wider than prothorax 

 (4-75 X 2-8 mm.), lightly convex, lightly declivous to base on
