In general appearance strikingly close to several species 

 of Ditropidus ( fuf/itiv us, siihsimiUs, aonicrudus, and the male 

 of elegantuliisj, but club of antennae distinctly with six 

 joints, instead of five, as on those species. 



EUDITROPIDUS PALLIDUS, n. Sp. 



d . Flavous, extreme base of prothorax and part of 

 abdomen infuscated. Head, under-surface, and legs with 

 very short pubescence. 



Head with small, dense, inconspicuous punctures, but 

 becoming sharply defined on clypeus; median line shallowly 

 impressed. Prothorax about twice as wide as the median 

 length, sides strongly narrowed to apex, somewhat gibbous in 

 front; punctures small but rather sharply defined, denser on 

 sides than in middle. Elytra suboblong; with rows of fairly 

 large punctures, becoming smaller posteriorly, and on each 

 side set in three deep striae ; interstices with very minute 

 punctures. Front l/^gs slightly longer than hind ones. 

 Length (d, 9), 2-25-2-75 mm/ 



9 . Differs in being more robust, eyes rather more 

 apart, prothorax shorter, abdomen larger, more convex, and 

 with a very large apical fovea, antennae and legs thinner, 

 and the front legs no longer than the hind ones. 



Hab. — South Australia: Leigh Creek (Blackburn's 

 collection). Type, I. 10975. 



A short, robust species, with vaguely ttiottled prothorax, 

 at first glance resembling some of the pale forms of 

 Polyachus geininas; in general appearance it is very different 

 from each of the three preceding species, but as the club is 

 certainly six-jointed and the scutellar lobe notched it has 

 been associated with them. On the female the metasternum, 

 as well as part of the abdomen, is sometimes infuscated; on 

 one specimen the abdomen is entirely pale; the club of the 

 antennae is usually no darker than the basal joints, but is 

 sometimes slightly infuscated. 



Elaphodes vulpinus, Suff. 

 E . illotus, Lea. 



E. illotus was named from a single female, but there 

 are now thirty specimens before me (from New South Wales, 

 Victoria, and South Australia), and these indicate that the 

 species is probably the most variable one of the genus; and 

 also that vulpinus, for which an exact locality was not given, 

 was founded upon other females. 



The male may be readily distinguished from males of 

 other species by the jaws, these being much larger than usual,
