Head distinctly transverse, hind angles strongly rounded off; with dense and 

 sharply defined punctures, becoming smaller in front, with two small inter-ocular 

 impressions, appearing like large punctures; basal slope with a shallow median 

 line. Eyes large and prominent. Antennae moderately long, most of the joints 

 submoniliform; eleventh as long as ninth and tenth combined. Prothoras about 

 as long as its greatest width, sides strongly rounded and widest near apes, where 

 the width is equal to that of head, deeply constricted towards base; densely and 

 rather strongly punctate, and with a conspicuous m'edian line. Elytra almost 

 parallel-sided, shoulders moderately rounded; with rather dense and large, seriate 

 punctures about base, rapidly becoming smaller and almost disappearing on apical 

 slope. Hind legs long and thin, the others shorter. Length, 2 — 2.25 mm. 



Hah. — Victoria: Mooroopna, in April (F. E. Wilson), Geelong (H. W. 

 Davey). 



Distinguished from T. leae by its larger size and densei and sharply 

 punctures on head and prothoras; T. denticoUis is described as having 

 scattered punctures on those parts. As there is a foveate impression on the 

 apical segTQent of abdomen, on the three specimens under esamination, they are 

 presumably all males. 



Tbichananca aptera, n.sp. 



Piceous-brown, under surface somewhat paler, legs and palpi flavous, 

 knees, tarsi and antennae slightly darker. Clothed with rather sparse, pale 

 pubescence, and with numerous subereet, dark hairs. 



Plead moderately large and, excluding mouthy parts, distinctly transverse, base 

 strongly rounded, with rather small and sparse, unevenly distributed punctures. 

 Antennae rather long and moderately stout, eleventh joint as long as ninth and 

 tenth combined. Prothorax distinctly longer than wide, strongly constricted at 

 basal third, with an in-egTilar median line; coarsely and irregularly punctate, or 

 granulate. Elytra rather narrow, shoulders rounded, sides gently dilated to be- 

 yond the middle; with rows of large, suboblong punctures, close together near 

 base, smaller posteriorly, and feeble about apex. Legs rather long and stout. 

 Length, 4 — 4.5 mm. 



Hab. — Queensland: Mount Tambourine, two specimens from rotting leaves 

 (A. M. Lea), Brisbane. 



An apterous species ; the only previously described .apterous one is T. con- 

 color, from which it differs in being darker, in having the head less transverse, 

 with smaller punctures, and longer and thinner antennae, the prothorax is also 

 decidedly longer, with naiTower median line, and different punctures. Struc- 

 turally, except for the want of wings, it seems near T. pisoniae, but the shoulders 

 are more rounded off, and consequently not so much wider than the base of the 

 prothorax. On one specimen the elytra have a faint coppery-green gloss. 



Trichas-anca miceomelas, n.sp. 



5. Black; antennae, coxae, trochanters and knees rather obscurely reddish, 

 palpi and tarsi paler. With rather sparse, pale pubescence, interspersed with 

 darker, subereet hairs. 



Head (excluding neck) distinctly transverse, hind angles rounded off; with 

 sparse and small punctures ; a shallow depression each side in front. Antennae 

 rather long and thin, eleventh joint as long as ninth and tenth combined. Pro- 

 thorax about as long as its greatest width, front sides strongly inflated and dis-
