200 Dr. E. Bergroth on new or 



but tlie head and pronotum ave differently coloured and 

 scarcely sericeous, the base of the tyliis between the aii- 

 tenufe is broader, not carinate, the eyes are smaller, the ante- 

 rior pronotal lobe is much more distinctly sculptured, the 

 posterior lobe less depressed, the metasternum is more shortly 

 and less distinctly carinate, the legs are shorter and not 

 annulated, the fore femora broader in their basal half, the 

 fore tibiae much more dilated, particularly on the inner 

 side, and the dilated part is differently shaped, their superior 

 apical fovea (for the reception of the tarsi) is much broader, 

 their spongy pit shorter and broader, the female venter is 

 carinated only on the two ba^al segments, the first male 

 genital segment is much more elongate, and the male genital 

 styles are black. 



In P. vittiventris the upper interocular space is only one- 

 third broader than an eye, the distance between the eyes and 

 the bucculee is distinctly shorter than the greatest diameter 

 of the eye (seen from the side) ; the two denudated spots of 

 the coiniexival segments are more or less pale, and therefore 

 much less conspicuous than in jmgil ; the fore femora pass 

 the apex of the head by one-third their length or more, and 

 are not or scarcely broader in their basal half ; the upper 

 apical impression of the fore tibice is very narrow, their 

 spongy pit narrow and only one-third shorter than the tarsi ; 

 the hind femora reach the apex of the abdomen ; the venter 

 is carinated in both sexes from its base to the apex of the 

 fifth segment ; the first male genital segment is equilaterally 

 subtriangular, and the genital styles are luteous. 



P. vittiventris, Bergr., and pugiJ, Bergr., form a distinct 

 section of the genus, intermediate in a way between the 

 typical Petalochiri and the subgenus Flatychiria, H.-iSch.
