Hub. — Western Australia: jMullewa (Miss J. V. May), imif|ue. 



A beautiful deep-blue speeies, very distinct from all others known to me by 

 the sculpture of the prothi>rax; at first ,y'lanee this apjiears to be densely longi- 

 tudinally strig'ose, but it is really densely punctate, the punctures everywhere 

 continent except on a small part of the scutellar lobe. The elytra are of the 

 same shade of colour as the prothorax, but owing to their smoother sui'face they 

 appear brightei-; the antennae are rather long for the genus, and the second-fourth 

 joints are i)artly or entirely red, the others being more or less deeply infu.scated. 

 The pygidiuni is glal)rous, and its jninctures are (|uite as sharply defined as those- 

 on the head. 



DiTnoHinrs py(;tiiialis, n.sj). 



(f. — Black; tiiree basal joints of antennae obscurely reddish. Under surface 

 and leg's with sparse pubescence. 



Head with dense punctures at base and on clypeus; median line wide, shallow,^ 

 and with smaller and sparser jnmctures than on the adjacent surface. Eyes 

 moderately separated. Pmthora.v at base not twice as wide as the median length, 

 sides strongly rounded; with sparse and minute punctures, the front angles finely 

 strigose. Eli/tra briefly suboblong, with rows of not very large punctures, at the 

 sides set in deep stria; interstices faintly wrinkled. Length (c?, ?), 2.6 — 3 mm. 



2. — Differs in being .slightly more robust, prothorax shorter, legs somewhat 

 shorter, and in the abdomen . 



Hab. — New South Wales: Sydney (A. M. Lea). 



There is a single specimen of each sex before me ; on the male the elytra have 

 a slight bluish or bluish-green gloss, but this is absent from the female; the dis- 

 tance between the eyes of the male is about equal to the length of the three basal 

 joints of antennae, in the female of the five basal joints; on the male the front 

 angles of the prothorax are densely and finely strigose, but the strigae are so very 

 fine that the surface at first appears to be slightly shagreened, on the female they 

 almost reach the vanishing- point; the hind angles from above appear to be acute, 

 and to slightly embrace the shoulders, but they are really almost rectangular; tlie 

 punctures on the pygidium are dense and subreticulate. 



DlTROPIDUS CARIN.WICEP8, U . Sp . 



2. — Blue; labruni, palpi, and second-sixth joints of antennae red. Under 

 surface and legs with sparse,- inconspicuous pubescence. 



Head large; with rather small but sliarjily defined punctures, becoming crowd- 

 ed and irregular in front ; median line well-defined ; clypeal suture marked by a 

 bisinuate carina. Eyes very widely separated. Prothorax about twice as wide 

 as the median length, sides strongly rounded, lateral gutters well-defined; punctures 

 small but sharply defined. Elytra sub-oblong; with rows of fairly large punc- 

 tures, on the sides set in deep striae; interstices witk sparse and minute punctures. 

 Abdomen with a large, round, deep, apical fovea. Length. 4.5 mm. 



Hah. — New South Wales: Forest Reefs (A. M. Lea), unique. 



The side of each elytron is gently incurved between the base and the sudden 

 deflection before the middle, the dilated part being unusually deep, and the sub- 

 lateral interstice cun'ing around on to it; the clypeus has two small transversely- 

 oval, impunctate areolets, each bounded behind by a narrow carina, and in front 

 by a more obtuse elevation (it is probably vei-y different in the male) ; these
