176 MONOGRAPH OF THE 
into a broad and obtusely rounded tooth. The maxillary palpi 
have the second joint very large, punctate, and almost subcordate ; 
the inner apical angle being rounded off; the labial palpi are 
separated at the base by a minute conical piece or scape, as in 
the type of the genus. The prothorax is bipartite, with the 
anterior part rather the widest, its sides being produced into 
rather acute angles, and its hind margin extended further back- 
wards than in the preceding; the middle part of the prothorax 
is distinguished by a deep transverse impression, with the margins 
elevated on each side. The elytra are much wider than the pro- 
thorax, opaque and rugulose, the rugee running together very 
irregularly. The feet are very much punctured, compressed, and 
rather broad, the posterior tibiz being slightly curved, and broader 
than the others. The calcaria* are wanting, being replaced by 
a few sete, similar to those at the tips of the joints of the tarsi. 
The abdomen has a slight notch at the anus, but is destitute of any 
external appendages.

This species is nearly allied to P. fulvus, but differs in its paler 
colour, narrow feet, pair of tubercles between the eyes, &c. The 
head is nearly as broad as the prothorax, pale luteous, finely 
rugose, the posterior angles behind the eyes rounded off, with a 
distinct neck, the fore margin or clypeus having a central notch, 
from whence extends an impressed line to the middle of the crown, 
where are two elevated tubercles excavated at the tips with a fine 
impressed line between each of them and the eyes. The clava of 
the antennz is large and strongly punctate, the anterior margin 
acute and curved, and the posterior considerably dilated and 
excavated, the sides of the excavated part being sinuato-tuber- 
* By a typographical error the tibiee of this species were described in the Linn, Trans. as 
© calcaratis,’’ instead of ‘* ecalcaratis.”
