‘structure being nearly allied to P. affinis and Hardwickii. The 
supposition of Donovan that this insect and P. Fichtelii are the 
sexes of the same species is certainly incorrect.

This species is most nearly allied to P. thoracicus, from which, 
however, it is abundantly distinct, the general shape of the clava 
of the antennz, and the number of elevations on the margins of 
the excavation being different ; the keel-like anterior margin of 
P. thoracicus is replaced by an obtuse and irregular fore-margin, 
the front of the head is more emarginate in P. thoracicus, and 
more distinctly quadrate behind the eyes than in this species, in 
which the impression on the crown of the head is much deeper and 
rounder than in P. thoracicus, and incloses two minute, elevated 
tubercles. 
The margins of the elytra are simply pubescent, whereas they 
are setose in that species; the lateral lobes of the mentum are 
long and acute; the extremity of the podex (which, seen from 
beneath, appears like a fifth joint of the abdomen) is furnished 
with two small tufts of short, thick hairs; the legs are compara- 
tively long and slender. 
Captain Boys describes two varieties of this species, which are 
evidently the sexes, one with the two diverging curved spines 
beneath the extremity of the abdomen (pl. 90, fig. 8 @), which is 
of an equal width throughout, and withthe margins cf the excava- 
tion of the clava of the antenne presenting the appearance of a 
screw; the other, destitute of the two curved spines (pl. 90, fig. 9 a), 
and having the crenulations of the prothorax, across the centre, 
more deeply sculptured and foliated, with the abdomen narrowed 
as it approaches the thorax. 
The former of these varieties, although considerably irritated,
