A very distinct groove runs obliquely from the inner articular angle to 

 the exterior edge of the mandibles (as in P. tesserinoda and sulcata) • 

 A much raised longitudinal carina in the middle of the clypeus (as in 

 P. insulana), which is slightly acuminated or toothed in the middle of its 

 anterior edge. Eyes smaller by half than in P. tesserinoda, situated on 

 the anterior quarter of the sides of the head. Head broad, a little 

 narrowed behind, and there broadly concave. The anterior edge of 

 this concavity forms a right angle with the anterior surface of thg 

 head. The perpendicularly truncate posterior surface of the occiput is 

 obliquely striate or wrinkled and shining. The sides of the head are 

 more or less flattened and submarginate. Head longitudinally striate 

 beneath, coarsely reticulate and finely granulate above (anteriorly). On 

 the forehead and the cheeks the reticulations pass into longitudinal 

 wrinkles. 



Thorax moderately short ; a lamelliform tooth at the anterior inferior 

 angle of the pronotum. The meso-metanotal suture wholly obliterated. 

 Declivous surface of the metanotum truncate, plane, oval, and margin- 

 ed by a small subdenticulate edge. This truncation is shining, trans- 

 versely wrinkled below, the wrinkles being more effaced above. Pro- 

 notum semicircularly reticulate-rugose, mesonotum longitudinally so, 

 both in addition with scattered and moderately effaced extremely coarse 

 puncture. The basal surface of the metanotum with an extremely coarse 

 and deep reticulate-punctate-rugose sculpture. 



Scale like that of P. tesserinoda, but nearly twice as broad as thick. 

 Its anterior and posterior surfaces are both truncate and transversely wrin- 

 kled. Its periphery has an extremely coarse and deep puncture, between 

 which it is rugose. A rounded hump under the petiole. 



Abdomen truncated anteriorly ; the truncation shining and nearly 

 smooth. The rest of the first segment reticulate-rugose (transversely 

 so in front, longitudinally behind) ; besides, it is very coarsely scattered 

 and effaced-punctured. The other segments of the abdomen are shining 

 and delicately, more or less effaced reticulate-rugose (transversely so 

 on the base, longitudinally so on the end of each), with scattered not 

 coarse puncture. Legs and antennae strongly punctured. 



The spurs of all the legs pectinate. Some rare scattered erect 

 hairs, especially on the tibiae and scapi. A short, much spaced applied 

 pubescence is scattered everywhere. This pubescence is extremely fine 

 on the abdomen. 



Brownish black. Abdomen dark reddish brown. Legs, antennae, 

 mandibles, lamincB frontales, and anterior edge of the head reddish. 

 Sibsagar.
