350 MEMOIRS OF THE QUEENSLAND MUSEUM. 
New South Wales : Upper Williams River, in October (A. M. Lea). 
Queensland : National Park, in November (H. Hacker). Male, in South Australian 
Museum ; female, in Queensland Museum. 
In the 1909 table of the genus 4 this species could be referred to A, as the front 
femora of the male are distinctly curved (although less so than on several species 
of the section), with large, projecting trochanters. Of the species placed there 
II. mirabilis and pirfcherrimiis have black antenna) (which arc also shorter), legs and 
scutellum, and the elytra have stronger punctures, and less of their tips pale ; the 
latter species also has much of the pronotum dark. Of the species with spurred 
hind tibiae in the female, this is distinct from H. dentipes and calcaratus by its larger 
size and bicoloured elytra ; the spur is blunt-tipped, and only about half the length 
of the first tarsal joint, but as it is alike on both tibiae it is evidently not broken. 
H. tricolor , with bieolorous elytra, has those organs dark blue, except at then* tips, 
and is a much smaller species. Prom some directions the hind tarsi appear to be 
but four -jointed, this being due to the second apparently continuing the lines of the 
first, but from other directions the junction between them is distinct. The purple 
band on the elytra of the male touches the margins, but on the female these are 
narrowly excepted, and the pale portion narrowly encroaches on it along the suture. 
Hypattalus armipes n. sp. 
• $. Black, flavous, and purple. With sparse, whitish pubescence, and short, 
suberect , dark setae. 
Head gently convex, with minute punctures. Antennae long, thin, and 
slightly serrated. Prothorax strongly transverse, with small punctures. Elytra feebly 
dilated to beyond the middle, the sides then suddenly narrowed and rounded to 
apex ; with dense, sharply defined punctures of moderate size. Legs long and thin, 
hind tibiae moderately curved, slightly dilated to apex, and with a long apical spur. 
Length, 3 mm. 
Queensland : National Park, in November (H. Hacker). Type (unique), 
in Queensland Museum. 
Another species with spurred hind tibiae in female, from the preceding one 
it differs in having the spur much longer, thinner, and curved (about one-fourth 
the length of the tibia itself), the elytra with basal and postmedian markings, and 
their sides very different (approaching those of the female of H. mucronatus). The 
black parts are the head, metasternum, and most of the antennae and legs ; the 
purple parts are the basal fourth of elytra, and two large postmedian spots, touching 
the sides but not the suture. 
Hypattalus pectinicornis n. sp. 
<$. Flavous, head and most of antennae black, elytra with basal fourth and 
a somewhat larger post median space p urple ; parts of legs infuscated. With sparse, 
whitish pubescence, and straggling, dark hairs. 
Head strongly transverse ; with two small foveae in front, and with minute 
punctures. Eyes prominent. Antennae rather long, first joint about twice as long 
as second, the latter rounded, third and fourth triangular, fifth-tenth pectinated, 
the teeth equal or subequal to their supporting joints, eleventh distinctly longer
