the anterior coxee and the mesosternum a little longer than broad, 
whereas in P. consobrina the prosternum is strongly narrowed between 
the anterior coxe, and the mesosternum is twice as long as broad ; in the 
male, moreover, the fifth joint of the antenne only is dilated, and the 
last ventral segment of the abdomen is impressed at apex with a small 
fovea. 
P. punctulata, Marsh. (@ea, All.). A small species, of a uni- 
colorous black colour with more or less distinct bronze reflection, which 
is often almost absent; the antennze have the base ferruginous, with 
the exception of a portion of the first joint, which is dark ; this point 
will at once distinguish it from the two preceding species, and from the 
two following is may be easily separated by its much finer and more 
confused punctuation. L. 143-2 mm.

brook, Essex; Ditchingham, Suffolk; Margate ; Devon; Bristol ; Swansea; Need-

P. atra, Payk. Of a deep shining black colour, without metallic 
reflection, antenne with the first four joints ferruginous, the base of the 
first and the apex of the fourth being brownish ; thorax considerably 
broader than long, with sides rounded, thickly punctured, the punctua- 
tion being evidently finer than on elytra ; elytra long, separately rounded 
at apex, rather strongly punctured, the punctures being arranged in 
rather distinct rows towards base; legs black, tarsi and knees lighter.

ford (Power). 
P. crucifer®, Goeze (peciloceras, Com. ; obscwrella, Il.). Asarule 
a little larger and broader than the preceding, which it very closely 
resembles ; it may, however, be distinguished by the fact that the upper 
surface always has a greenish or bluish metallic reflection and by the more 
clear testaceous colour of the base of the antenne; the thorax is nearly 
as strongly punctured as the elytra, and the punctures of the latter are 
disposed in more regular rows. L. 13-23? mm.

P. vittula, Redt. A small species, oblong-ovate, rather depressed, 
black with the thorax metallic greenish or coppery, and the elytra with 
a yellow longitudinal band on each, which is feebly emarginate on its 
outer margin, and on its inner side is somewhat strongly curved inwards 
at base; it is also abruptly truncated or emarginate at shoulders, owing to 
the black colour of the humeral callosity ; head with the front and
