 Rangoon. 



In a small series of examples exactly alike in size and colours, 

 one only (from Rangoon) agrees with Schmidt-Goebel's de- 

 scription as regards the outline of the thorax. He says the thorax 

 forms a "fiinfeck" the two hinder sides uniting in an obtuse very 

 slightly truncated angle at the base, thus implying that the sides 

 from the prominent lateral angle to the base are straight. This 

 applies well to the Rangoon example; and not to the others from 

 Karin Gheba in which the posterior sides are strongly flexuous 

 or sub-angulate-rotundate about the middle of their length. As 

 this peculiarity exists in P. nigripennis (Bates) from Japan which 

 otherwise presents only trifling differences I refer the Karin 

 Gheba form to that species ; it is probably, however , that this 

 difference in thoracic outline is variable and that the two forms 

 are only varieties of one and the same species.

(') The p. ruficollis, Bates, Trans. Ent. Soc, 1873, p. 320, proves to be quite di- 

 stinct from the species of Schmidt-Goebel and therefore requires describing under 

 a new name: — P. Oaimiella- — P. ruficolli major et differt elytris longioribus se- 

 riceo-opacis, striis obsoletis perspicue punctulatis interstitiis paullo convexis. Rufo- 

 testacea capite toto cum antennis et palpis elytris abdoraineque nigris; scutello, 

 elytrorum margine laterali epipleurisque rufotestaceis , thorace lateribus posticis 

 leviter excurvatis nee subangulatis. — Long. 6 millim.
