394 COLEOPTERA. 
3852. Pheloneis dubitans sp. nov. 
_ Elongate - oblong, moderately convex, nitid; aeneo - niger, legs rufo- 
plceous, antennae and tarsi fusco-rufous; with a few slender erect setae, 
the thorax with minute pubescence. 
Head moderately closely and finely punctate, with an elongate inter- 
ocular fovea. Thorax about a third broader than long in the middle, 
distinctly marginate, almost quite straight from the rectangular posterior 
angles to near the middle, moderately curvedly narrowed anteriorly, apex 
evidently and widely incurved, the base less so; its punctation like that 
of the head, with an elongate depression at each side behind the middle 
and a small basal fovea between the middle and side. Scutellum strongly 
transverse. Elytra of about the same width as thorax at the base, nearly 
thrice its length, curvedly narrowed behind; each with about 10 dorsal 
finely punctured striae, those near the sides less distinct ; interstices with 
numerous fine punctures. 
Underside shining, minutely pubescent, the legs more distinctly. Pro- 
sternum almost smooth, mesosternum closely punctured, the terminal 
segment more closely and distinctly punctured than other parts of the 
abdomen. 
At first sight I thought this might be Sharp’s Adeliwm simplex (2049), 
but as the elytral interstices are described as almost impunctate, but the 
striae rather coarsely punctate, and as it seems to be destitute of pubes- 
cence, I now consider it distinct. No. 1404, from Mount Arthur, is another 
near ally, but it has a longer thorax with several coarse punctures like 
those of P. thoracicus (694). 
Length, 83-9 mm. ; breadth, 3} mm. 
Mount Dick. Five examples from Mr. T. Hall, some imperfect, taken 
on the 10th March, 1914. The erect setae seem to be easily rubbed off. 
A specimen from Ben Lomond, on the 6th March, 1914, measures 10 mm. 
by 44 mm, 
3853. Pheloneis curtulus sp. nov. 
Oblong, subparallel, moderately convex, nitid, apparently glabrous ; 
aeneo-niger, legs piceo-rufous, antennae and tarsi slightly paler. 
Head finely and closely punctate. Thorax subquadrate, about a third 
broader than long in the middle, its sides distinctly margined, nearly 
straight, a little curvedly narrowed before the middle, apex widely emar- 
ginate, base subtruncate, posterior angles somewhat obtuse; its surface 
regularly, finely, and closely punctured, with an elongate impression near 
each side before the middle, and a small basal fovea near each side. Scutel- 
lum transverse, with some minute punctures. Elytra very slightly wider 
than thorax at the base, rather more than double its length ; rather closely 
and finely punctured, each elytron with about 4 fine, irregular, nearly 
obsolete striae; these, however, scarcely extend further back than the 
posterior femora. 
P. lentum (692) has a triangular excision at the base of the thorax, but 
nevertheless the scutellum is invisible, otherwise this seems to be little 
more than a varietal form. 
Length, 7 mm.; breadth, 3} mm. 
Ben Lomond; 31st January, 1914.° Mr. T. Hall is the discoverer.
