P. carnose, Baly) fusco-punctulatis, interstitiis levibus 
obsolete irregulariter (fere ut P. obsolete, Oliv.) ineequalibus, 
angulis humeralibus (a latere visis) rotundatis, vix deorsum

This species is much like P. carnose, Baly, in general appear- 
ance and is similarly colored, having many of the rugulose 
interstices of the elytra yellow so as to produce the appearance 
of the elytra bearing numerous small yellow specks, which are 
unevenly distributed in such fashion that the elytra can be 
regarded as having yellow as their ground color and three 
indistinct reddish fascie as their markings; in none of the 
specimens I have seen of this insect is there any trace of the 
obscure dark piceous patches that are generally more or less 
traceable on the elytra of P. carnosa.. From P. carnosa the 
present species differs in the prothoracic puncturation being less 
close and being arranged in clusters, also in the interstices of the 
elytral puncturation being less convex—so that the punctures 
themselves are much more conspicuous, the punctures in P. car- 
nosa being less noticeable on account of the depth of the 
inequalities in which they lie. I have a single female example 
which is too much broken for exact description, but evidently 
scarcely differs from the male except in the usual sexual respects, 
7.€., narrower form, shorter antenne, &c.

P. mutabilis, sp. nov. Mas. Late ovata, apicem versus fortiter 
dilatata ; convexa; minus nitida; sordide viridis (nonnul- 
lorum exemplorum mortuorum colore plus minus in rufo- 
testaceum transeunti), antennis apicem versus infuscatis ; 
capite longitudinaliter vix impresso cum prothorace sat 
crebre fortius punctulato (fere ut P. carnose, Baly); anten- 
nis quam corporis dimidium vix longioribus, articulo 3° quam 
1% haud longiori ; prothorace quam longiori plus quam duplo 
latiori, antice vix sinuatim fortiter emarginato, postice 
leviter bisinuato, ad latera sat crasse ruguloso, lateribus 
minus arcuatis fortiter bisinuatis, angulis anticis mucronatis. 
posticis fere nullis ; elytris quam longioribus paullo latior-
