 in front ; mesonotum convex, smooth and shiniog in the middle ; 

 scutellum large, prominent, without punctures in the middle ; 

 median segment rounded posteriorly, with a narrow central 

 longitudinal furrow from base to apex, the apex and sides 

 pubescent; legs with the tibijB and tarsi, especially of the posterior 

 pair, strongly spinose ; abdomen broad and about as long as the 

 head and thorax together. Black ; the mandibles except at apex, 

 the clypeus, a semicircular spot above it, the inner orbits as high 

 as the emargination of the eyes, a line along the outer orbits not 

 reaching the vertex, a line on the pronotum, the tegulse, a line 

 on the posterior margin of the postscutellum, two small lateral 

 spots on the median segment, the femora, tibiae and tarsi of the 

 anterior legs, the apex of the femora, the tibiae, and tarsi of the

Sab. Tenasserim. 



Resembles the preceding species, but differs in the shape 

 of the median segment and scutellum, and considerably in the 

 markings. It is smaller than the type of P. basalls, Smith, 

 in the Museum, and differs also from it in the markings and in 

 the sculpture of the thorax.

 at base and down a central line to the apex, the apex on either side 

 closely punctured and pubescent ; the legs punctured and covered 

 with a thin fine pubescence ; abdomen shining, with the bases 

 of segments 2-5 broadly depressed, the depressions forming 

 marked bands very finely transversely striate ; the basal segmeat, 

 the apical margins of the 2nd to 5th, and the apical two segments 

 finely and distantly punctured, the last slightly pubesceut at the

 porrect and broadly emargiuate in the middle anteriorly. The
