Laius trifoveicoenis, n. sp. 



<3 . Dark purple, some parts blackish ; prothorax, apex 

 of elytra, basal joints of antennae, and most of legs flavous. 

 With sparse, ashen pubescence, and long, dark hairs. 



Head gently concave in front; with dense and small 

 punctures. Antennae with first joint dilated at apex, 

 apparent second very large, lower-surface gently convex, 

 upper-surface with three irregular excavations. Prothorax 

 strongly transverse, sides strongly rounded; with fairly 

 dense punctures on sides, sparse elsewhere. Elytra almost 

 parallel-sided to near apex, sides and suture slightly 

 thickened, apex base and sides with rather small and rugose 

 punctures, denser, larger, and more rugose elsewhere. Second 

 joint of front tarsi lopsided, with a black outer comb. 

 Length (tf , 9), 2'75-3 mm. 



$ . Differs in having the head smaller, apparent second 

 joint of antennae simple, and second joint of front tarsi 

 similar to the third. 



Hab. — Australia (old collection); South Australia: 

 Moonta (Blackburn's collection). Type, I. 7582. 



The elytra are coloured almost as in L. mwocerus, but 

 the two species have little else in common, from some 

 directions they appear to be multigranulate. The pale apical 

 portion occupies about one-fourth of the length at the 

 suture, where it is longest, and then curves round to each 

 side so as to resemble the figure 3, but it is very narrowly 

 continued along each side almost to the base; the antennal 

 joints, after the apparent second, are more or less infuscated. 



Laius albomaculatus, n. sp. 



d" . Black; parts of basal joints of antennae flavous, four 

 large spots, and parts of extreme base of elytra, almost white. 

 With fairly numerous, erect, dark hairs. 



Head gently convex, with a small fovea in middle and 

 two feeble depressions in front ; with dense and sharply defined 

 punctures. Antennae with first joint moderately long, the 

 apparent second much larger, gently convex on lower-surface, 

 irregularly concave on upper-surface, the outer front angle 

 conspicuously produced, many of the following joints trans- 

 verse. Prothorax widely transverse, apex much wider than 

 base, a shallow depression near base ; with dense and sharply 

 defined punctures on sides, sparser elsewhere. Elytra with 

 sides slightly dilated to near apex, sides and suture thickened; 

 with dense and sharply defined punctures on most of the 

 dark parts, sparser and smaller on the pale parts. Second 

 joint of front tarsi lopsided, with a black outer comb. 

 Length, 2*5 mm;
