tures moderately large, oblong or suboblong, sometimes with 
slightly wrinkled walls; interstices not separately convex, 
much wider (at base not much wider) than punctures. Ab- 
domen irregularly punctate, the punctures of the two basal 
segments never very large, and not very dense, a few larger 
than the others on second ; third and fourth each with a 
single row of squamose punctures. Length, 5 ; rostrum, H ; 
width, 2^ mm. 
7/«6^— South Australia (Rev. T. Blackburn, No. 1493). 
The prothoracic punctures are fully as large as in foravii- 
nosus, but those on the elytra are very much smaller than in 
that species. The clothing of the under surface shows a 
slight approach to that of auricomus and tihialu. Mr. 
Blackburn informed me that the specimens described were 
probably taken near Adelaide. 
Decilaus irrasus, n. sp. 
Sparsely and irregularly clothed with brown and whitish 
scales, forming in places indistinct spots. Sterna and basal 
segments of abdomen with elongate whitish scales ; pectoral 
canal almost glabrous. 
Head densely and coarsely punctate. Rostrum mode- 
rately stout, sides feebly incurved to middle ; coarsely punc- 
tate, punctures subseriate in arrangement between antennae and 
base. Scape inserted three-sevenths from apex, the length of 
five following joints; of these the first is noticeably longer 
than the second. Froth ova r moderately transverse, basal 
two-thirds almost parallel sided, with rather large, round, 
clearly-cut punctures, which become smaller towards apex. 
Elytra oblong-cordate, base almost truncate ; seriate-punc- 
tate, punctures moderately large, deep, oblong, or suboblong ; 
interstices not separately convex, narrower than punctures and 
rather coarsely punctate. Ahdot/ien with the two basal and 
the apical segment irregularly but not densely punctate ; 
some of the punctures rather large. Length, '6-^ ; rostrum, 
IJ ; width, 1{! mm. 
Hah. — Queensland (Australian Museum). 
The prothoracic punctures are about the size that they 
are in dfstam^, but those on the elytra are considerably 
larger. 
Decilaus auricomus, n. sp. 
Clothed with pale fawn-coloured and whitish scales : pro- 
thorax with three feeble lines of rather stout elongate scales : 
elytra not very densely clothed with soft, almost round scales, 
a few of winch are of an almost pearly whiteness. Middle of 
metasternum and two basal segments of abdomen and the 
four posterior coxae with long, slightly curved, golden set.?e or
