HORN EXPEDITION—COLROPTERA. 
P. C07ife7-tn., Chp. (2), Palm Creek. These specimens seem to be identical 
with an example in my possession received through M. Severin from Dr. Chapuis’ 
collection. The principal chai'acter distinguishing this species from its immediate 
allies in the extremely difficult section of Dr. Chapuis’ “ Croupe III.” to which it 
pertains appears to be the confusion and irregularity of the crowded punctures of 
its elytral striie. 
P. posticalis, sp. nov. (3). Ovalis ; parum convexa; nitida; flavo-testacea, 
capite rufescenti, elytris apicem versus fascia maculari nigra insignibus ; capite 
subtiliter subcrebre punctulato; prothorace quam longiori paullo plus quam duplo 
latiori, subtilissime sat crebre (latera versus confertim subcrasse) punctulato, antice 
sinuatim minus profunde emarginato, postice leviter bisinuato, lateribus parum 
arcuatis, angulis anticis obtusis posticis (superne visis) fere rectis ; elytris quam 
latioribus sat longioribus subtiliter regulai’iter striatis, striis subtiliter confertim 
regulariter (apicem versus magis fortitei’) punctulatis, interstitiis plants (apicem 
versus vix convexis) crebre subtilius (quam striis magis subtiliter) punctulati.s, 
humeris (superne visis) fere recti.s, angulis humeralibus (a latere visis) deor.sum 
nullo modo productis, margine laterali subtiliter incrassato ; prosterno ante coxas 
jequaliter convexo, inter coxas angusto, pone coxas dilatato. Long. 21 1. 
Lat. 1-j"^ 1. 
This species resembles P. Hera^ Stiil., but is a considerably narrower species 
(approaching P. turlmta, Chp., in build) with its prothorax very much less trans¬ 
verse, its puncturation throughout very much finer, and the sub-apical black fascia 
on its elytra differently shaped, the said fascia running straight across the suture 
(instead of being curved with its convexity directed hindward). 
Crown Point. 
P. sp. nov. ? (4), Stevenson R. This very minute (Long. 1 1) species appertains 
to a section of Dr. Chapuis’ “Groupe ITT.,” containing numerous species, very few of 
which have been described, and I do not think it is desirable to describe isolated 
members of it. I hope at no distant date to attempt dealing with the section 
collectively, when it may be possilde by comparing one species with another to 
indicate the characters so that they can be identified; but I do not see how to do 
this without describing a number of new forms. P. chlorotica, Boisd., is a member 
of this section. 
P. fimerea, sp. nov. (5). Sat late ovata; sat convexa; sat nitida; rufo- 
castanea, nigro multo notata (sc. margine laterali toto, prothoracis parte antica et 
macula utrinque prope marginem lateralem, elytroruin sutura callohumerali pustulis
