222 MEMOIBS OF THE QUEENSLAND MUSEUM. 



a fairly large liut ill-defined pale spot on each elytron ; one female of the variety- 

 is still attaehed to a male of B; another female has a part of the sentellar lobe 

 pale: one male from Gladstone (Queensland) of the variety agrees perfectly 

 in outlines with the typical male, but has distinctly coarser punctures on both 

 prothorax and elytra; its elytral spots are very obscurely defined, and the legs 

 iwv] prosternum are almost entirely dark. Hah. — Queensland, New South Wales, 

 South Australia. 



Var. E. — Head and prothorax coloured as on the typical form, but elytra 

 with the red extended to cover most of the surface, excluding a rather narrow 

 but somewhat zigzag strip at the base ; the suture is also very narrowly dark, 

 but near the apex the dark part is dilated to form an oval spot ; the apex, 

 however, is entirely pale. Hah. — Queensland (Charters Towers). 



Var. F. — Head and prothorax entirely pale reddish tiavous, except that 

 the base of the latter is very narrowly black; elytra flavous, the base and suture 

 very narrowly black, a narrow part of the apex black, but the black part slightly 

 advanced along the suture and sides, so as to be strongly bisinuate on its inner 

 edge. On this variety, except for the claws, the legs are entirely pale. Hah. — 

 South Australia (Moonta). 



There are other varietal forms before me, but I have not considered it 

 advisable tu attach letters to those of which I have seen but one specimen. It 

 is probable that se^'cral published names will have to be treated as synonyms o^ 

 the species. 



DITROPIDUS IGNITUS sp. nov. 

 ^ Brilliant coppery red, in places coppery green, under surface and legs 

 black, with a bluish gloss; labrum and basal half of antennie reddish. Under 

 surfnceaud legs with rather sparse pubescence. 



Head with sharply defined punctures of medium size ; median line distinct. 

 Eyes separated about the length of two basal joints of antenna. Prothorax 

 at base more than twice as wide as the median length, sides strongly rounded ; 

 with dense, sharply defined, and not very small punctures. Elytra not much 

 longer th?m tlie basal Avidth, which is almost twice that of the apical; with rows 

 of not very large punctures, on the sides set in deep striti^ ; interstices with small 

 and fairly numej-ous punctures. Legs moderately stout, front ones slightly 

 longer than hind ones. Length ( (J9 ), 2-5-3 mm. 



$ Differs in being slightly more robust, eyes about one-third more distant 

 from each other, elytra less narrowed posteriorly, legs somewhat thinner, the 

 front ones no longer than the hind ones, and in the abdomen. 



Hah. — Queensland: Cairns (E. Allen) ; Bowen (Aug. Simson). — Type, 

 7. 10925 in South Australian Museum ; cotype, G/2317 in Queensland Museum. 



A beautiful, briefly oblong-elliptic species, in general appearance close to 

 D. rcnustus and fairly close to D. costatus, but distinguished from both by the 

 non-strigose sides of prothorax; the punctures there are not even confluent, and
