520 NEW SPECIES OF AUSTRALIAN COLEOPTERA, xi., 



front, middle depressed towards base, which is triangularly 

 notched. Clmvs strongly and acutely dentate. Length, 8mm. 



//a6.— Queensland: Cairns (E. Allen). 



With the wide intercoxal process of A, iridea, but the same 

 not so densely hairy, cl\^peal suture much less pronounced, head 

 generally smooth, and colour very different. In general appear- 

 ance, it is like some of the smaller forms of A. hypochalcea^ but 

 the claws are more strongly armed, the posthumeral depression 

 is much less conspicuous and is without a fovea. Only four 

 joints (which are rather thin) of one antenna are left on the 

 type, and but one of the other, and, of these, the third and fourth 

 are almost entirely dark. 



^SERNIA TRIPARTITA, n.sp. (Plate xlviii., fig.8). 



Head, prothorax, basal joint of antennse (the others purplish), 

 palpi, part of femora, and apex of abdomen fulvous-red, scutellum 

 and basal three-fifths of elytra brassy-green, apical two-fifths 

 fliavous, undersurface mostly brassy-green, becoming purplish on 

 legs. 



Head with a few scattered punctures, with a large subtrian- 

 gular depression; clypeal suture semicircular and well-defined. 

 Prothorax about twice as wide as long, towards each side with 

 two, irregular, coarsely punctured fovese; a few distinct punctures 

 on each side at base, elsewhere almost or quite impunctate. 

 Elytra at base not much wider than prothorax, sides dilated to 

 beyond the middle; with irregular rows of punctures, distinct 

 and well defined on brassy-green portion, very irregular and 

 much smaller elsewhere, with three transverse series of impres 

 sions containing coarse punctures on each side behind the 

 shoulder, a large semicircular depression on each side of base. 

 Length, 13^-18 mm. 



Hah. — Queensland: Coen River (H. Hacker). 



Differs from yE. australica in its uniformly coloured head, and 

 the flavous portion of the elytra occupying much more of the 

 apex. It is apparently closer to the typical form of yE. lafe/as- 

 ciata, but difi*ers from the description of same by having the 

 elytra (of three specimens) not metallic-blue, each at base with
