EXPLANATION OF THE PLATE. 
. Part of Ist and 2nd abdominal segments of P. parca Sauss., in lateral 
aspect. 1d. 1st dorsal segment; 2d. 2nd dorsal: 2v. 2nd ventral. 
. Part of the first and the following segments of P. icarivides P. The third 
and fourth segments were withdrawn within the second. 
. Part of first and second abdominal segments of P. tuberculatus Sauss., in 
lateral aspect. 
. Median longitudinal section of the 2nd ventral segment of P. olovis in 
lateral aspect (diagrammatic). 
. The same of P. tricolor LP. 
. The same of P. solitarius P. 
The same of P. alexandrie P. 
. The same of P. mutabilis P. 
. The same of P. multicolor P. 
. Apex of clypeus of P. imitator, very lightly emarginate. - 
. The same of P. dentiger, somewhat strongly emarginate. 
. The same of P. optabilis (clypeus quasi tri-dentatus). 
. The.same of P. atripennis (also quasi tri-dentatus). 
. The same of P. pseudochromus (clypeus fortissime emarginatus). 
. The same of P. subplebeius; clypeus truncate, but slightly rounded. 
. The same of P. oloris (clypeus recte truncatus). 
. The five apical joints of the antenne of P. punctulatus 3. 
. The small 9th, 10th and 11th antennal joints of P. hilaris, and the apical 
portion of the 8th, in the terminal cavity of which the others lie. 
. Three terminal joints of P. multicolor, the two latter very small and 
lying in the apical cavity of the 8th. 
. Tegula of P. debilis, showing the coarse puncturation of its outer portion. 
. The same of P. orientalis. The coarse punctures are uot equally 
numerous in all examples, but the sculpture is very different from that 
of species which have the tegulz very minutely punctured. 
. The same of P. alexandria. ‘The other parts of the tegul are, of course, 
sculptured, but only that part (or some of that part) which gives the 
best specific characters in different species is shown in this and the 
preceding figures.
