The whole insect, except the apex of the mandibles, is of a 
dull flavous color and looks as if it were made of wax. The 
sculpture of the elytra, except close to the suture, appears to 
consist of a system of closely-placed deep sinuous wrinkles, among 
which the interstices are more or less elevated or verrucose ; 
towards the front part of the dilated margin there are some 
coarse punctures distinctly visible.

P. affinis, sp. nov. Fem. Subrotundata; valde convexa; sat nitida ; 
testaceo-brunnea, antennis extrorsum atris, mandibulorum 
apice elytrorum puncturis et sternorum partibus nonnullis 
infuscatis; capite modice punctulato, pone clypeum quali ; 
antennis modicis, articulo 3° quam 1° vix longiori ; protho- 
race quam longiori paullo plus quam duplo Jatiori, antice 
sinuatim fortiter emarginato, postice bisinuato, in disco 
acervatim sat fortiter vix sparsim (ad latera crassissime) 
punctulato, interstitiis vix manifeste punctulatis, lateribus 
modice arcuatis, angulis anticis mucronatis posticis fere 
nullis; elytris quam longioribus paullo latioribus, fere ut 
P. variolosi, Marsh., sculpturatis (7.e., modice crebre fusco- 
punctulatis et verrucis sat numerosis obsolete elevatis ornatis), 
angulis humeralibus (a latere visis) rotundatis deorsum parum 
productis ; prosterno modico longitudinaliter sulcato. Long., 
621; lat, 441. 
This species, perhaps, is nearest to P. variolosa, Marsh., from 
which it differs by its shorter form and greater convexity (the 
height of the insect being to the length of the elytra as 7 to 12; 
in variolosa it is as 7 to 13), its antenne deep black outside the 
fifth joint, its head not longitudinally impressed, &c. I have 
seen only a single specimen of this insect, which is in my own 
collection.
