3rd, 5th and 7th interstices more strongly raised, 3rd forming a 

 strong ridge posteriorly; 1st and 2nd convex, punctulate, 4th and 

 6th lightly convex, summits rounded, punctulate. Length, (J 16, 

 9 17; breadth, $ 6-2, $ 7 mm. 



Hab. — Q. : Rockhampton (Jide Castelnau), Burnett River 

 District (Spencer; Coll. Sloane) — N.S.W. : Glen Innes (Sloane). 



My specimen ((J) from the Burnett River has been used for 

 the description given above. A second specimen (9 without 

 localit}') is in my collection; it has the prothorax much wider 

 (4'2 X 5-1 mm.), much wider at base (3-5 mm.), sides less strongly 

 narrowed and less sinuate posteriorly, lateral margins more 

 explanate. A specimen ((J) which I took at Glen Innes has the 

 same measurements as the ^ described above, but is a little more 

 depressed, with the elytral spots darker, though not such a dark 

 red as in F. mastersi, SI. 



I feel no doubt of the identity of this species, but it is not the 

 species Chaudoir noted as E. alternans in his 'Monograph'; he 

 seems to have overlooked the fact that Castelnau, in a note 

 appended to the description of E. rockhamptonensis, said the 

 elytral spots of his E. alternans and E. rockho,mptonensis were 

 orange, for in the ' Monograph ' the name E. alternans is attached 

 to a species with red elytral spots. Some confusion seems to 

 have occurred in Castelnau's paper in regard to the size of these 

 two species, where E. rockhamptonensis, 7 lines in length, is said 

 to be smaller than E. alternans; but the size of E. alternans is 

 given as 7 lines (probably it should read 7 J lines); this evidently 

 helped to mislead Chaudoir, for his E. alternans is too small. 

 (Length 13-5-14 mm.). 



Epicosmus mastersi, n.sp. 



Elliptical-oval. Prothorax depressed (9 with disc more convex 

 in middle and more declivous to sides than ^J), strongly and a 

 little sinuately angu state to base, much wider at base than apex; 

 elytra depressed between 5th interstices (more convex in ^ than 

 in 9), 3rd, 5th and 7th interstices more raised than the others 

 (but 4th and 6th costate), 3rd forming a strongly raised costa
