new Species of Histeride. 371 
largest along the base ; the thorax, anterior angles somewhat 
depressed, punctured laterally, points fine or evanescent on the 
disk, antescutellar fovea small and shallow, marginal stria 
complete but very fine behind the head; the elytra, striae, 
outer humeral apical and dimidiate, inner humeral wanting, 
1-4 dorsal complete, 5 apical, not quite dimidiate and some- 
times punctiform, sutural apical, parallel to the suture, and 
extending just beyond the middle, the apices of the elytra are 
sparingly punctured; the propygidium and pygidium are 
evenly but not densely punctured (7. e. very similar to those of 
cyanescens, Kir.). ‘The prosternum is narrower than in Erich- 
son’s species, and the striz are consequently nearer together 
and posteriorly are relatively more divergent; the meso- 
sternum is margined with a stria, which is simply bowed 
anteriorly, not sinuous as in cyanescens. The anterior tibize 
are 4-dentate, the apical tooth being minutely bifid. 
This species is nearly the same size and shape as P. cya- 
nescens, Kir., and P. ceruleatus, Lew., but the thorax is rather 
more narrow anteriorly and the outline therefore somewhat 
more oval.

Acacia-bark (Guy A. K. Marshall). 
Baconia jubaris, sp. n. 
Late ovata, depressa, supra viridis metallica, pedibus obscure brun- 
neis; fronte concava; pronoto post angulos impresso; elytris 
striis 4-5 et suturali nullis; prosterno bistriato; mesosterno, 
stria marginali late interrupta, stria transversa tenuiter im- 
pressa ; tibiis anticis 5-dentatis. 
L. 25 mill. 
Broadly oval, depressed, above green and metallic, head 
and thorax with a slight golden tinge; the head, forehead 
concave, finely striate over the eyes, punctate, points not 
dense but varying in size, largest are near the middle of the 
base, the labrum is narrow, transverse, and straight anteriorly ; 
the thorax, marginal stria complete, anterior angles rounded 
off, with an oblique impression behind them, the punctuation 
is extremely fine on the disk, closer and larger and a little 
rugose on the sides ; the elytra, striz, inner humeral very fine 
and complete, 1 also complete, 2 complete but somewhat 
evanescent at the base, 3 basal evanescent and punctiform on 
the apical half, the apical border is punctured but not densely, 
and there are similar punctures on the pygidia; the pro- 
sternum, anterior lobe is margined anteriorly with a fine stria, 
keel bistriate, strive parallel at the sides, finest and almost
