ber (occasionally eleven), the apical one is sometimes semidouble, and rarely ap- 

 pears as two. The elytra are evenly convex without a sub-basal depression, and 

 the hind tarsi are slightly longer than the tibiae. The male diffei's from the 

 female in having the abdomen smaller, less convex, and with the apex notched. 



Mecynotahsus hoetensis, n.sp. 



Derm normally concealed but mostly dark reddish-brown, under surface paler, 

 legs, antennae and palpi more or less flavous. Densely clothed with subsquamose 

 pubescence, silvery white on under surface and legs, variegated on upper surface. 

 Length, 2 — 2.5 mm. 



Ha&.^Western Australia: Swan River, common in gardens (A. M. Lea). 



With about the same range of size as in M. ziczac, but elytral markings 

 darker, more sharply defined and somewhat different in pattern, and average 

 number of tubercles on prothoracic process less. On the upper surface the pale 

 scales are usually darker than on the. under surface; on the prothorax there are 

 usually two ill-defined dark spots at the base; on the elytra there is a conspicuous 

 brown, or purplish-brown median fascia, not touching sides or suture, and with 

 more or less jagged outlines, occasionally the part on each elytron is obscurely 

 connected along, but not on, the suture, with a less distinct basal infuseation, be- 

 yond the middle the suture is narrowly dark, and then the dark part suddenly 

 dilates to a large and almost circular apical spot. There are usually nine tubercles 

 on the outer edge of the prothoracic process, but on several specimens the two 

 basal ones on one side are sometimes conjoined so that there appear to be but 

 three on one side. 



Mecynotabsus phanophilus, n.sp. 



riavo-castaneous, head and prothorax darker, legs, antennae and palpi paler. 

 Densely clothed with white or whitish pubescence, on the elytra variegated with 

 median and subapical markings. Leng-th, 2.75 mm. 



Hah. — Queensland: Cairns District, to light (A. M. Lea). 



At first glance like some varieties of M. ziczac, but prothorax with only nine 

 tubercles on the outer edge of the process, the, process itself shorter and wider, 

 and the part of the jarothorax behind it distinctly transverse, with its greatest 

 width very little less than that of the base of the elytra; lines drawn to connect 

 the apical tubercle with the basal one on each side, and these with each other, 

 would represent an equilateral triangle ; on ziczac the triangle would be a narrower 

 one, and the outer lines somewhat rounded. On the only two specimens taken, 

 the clothing being in perfect condition, the surface has not been abraded to be 

 sure as to the colour of the derm, although it is evident that the elytra are paler 

 than the rest of the upper surface, but the tubercles on the prothoracic process 

 are (except for sparse pubescence) glabrous, and dark castaneous. On the pro- 

 thorax the clothing is denser and more uniform than on the elytra, on the latter 

 there are four pale brown spots (disconnected on one specimen, connected two and 

 two on the other) representing a median fascia, and a short line directed obliquely 

 backwards on each side from the suture at the apical fourth. 



Mecynotaesus lateroalbus^ n.sp. 



Dark castaneous. parts beneath the pale clothing paler, legs, antennae and 

 palpi paler. Upper surface with dense chocolate-brown clothing, slightly varie- 

 gated on prothorax, and with two conspicuous white patches on the side of each 

 elytron; under surface and legs with white clothing. Length, 2.5 — 2.75 mm.
