 p. 399, $ . 



" . Length 4'8 mm. Very close to P. furcata, Smith, from 

 which it differs by the following characters : Head longer than 

 broad ; scape more slender. Clypeus not carinate ; a raised margin 

 in the place and position of the frontal sulcus. Thorax less 

 convex ; spines of the metanotum shorter than in typical 

 P. furcata, but longer than in P. gracilior. The node or column 

 of the pedicel is lower and much thicker (nearly as long as broad), 

 with the upper surface inclined from front to back and terminated 

 in front by a somewhat acute protuberance. The spines of the 

 columnar node are nearly horizontal, elongate, slightly encircling 

 the abdomen (as in P. gracilior), but never recurved at apex. A 

 longitudinal lobe under the pedicel (there is a tooth in P. furcata). 

 Sculpture very coarsely reticulate as in P. furcata but this 

 sculpture extends on to the posterior half of the head, which in 

 P. furcata is smooth and shining. Front of the head somewhat 

 smooth, sparsely punctured. Abdomen smooth and shining. 

 Pilosity and pubescence as in P. furcata, but the pubescence on 

 the abdomen is more abundant, on the thorax more sparse. Of a 

 dark red. Scape, abdomen and the apex of the spines blackish ; 

 tibia; and tarsi brownish." (Forel.) 



Hob. I procured this species myself in the Ye valley, Tenasserim, 

 but unfortunately have no specimens to refer to now, so I 

 reproduce Dr. Forel's description.

" . Length 8 mm. Black, opaque ; the head has a very sparse, 

 the thorax and node of pedicel a more abundant fine yellowish 

 recumbent pubescence ; the abdomen, however, is densely clad with 

 a recumbent golden pile. The antennal carinaj are moderately wide 

 apart, in front nearly as wide apart as posteriorly. The clypeus 

 is arched anteriorly, in the middle almost triangularly incised, and 

 toothed on each side near the emargination, veiy shortly carinate 

 posteriorly below the frontal area. The scape of the antenna) is 

 stout, somewhat thickened towards the apex. Mandibles longi- 

 tudinally striate, with scattered shallow punctures. The head is 

 coarsely intricately rugose, and in the intermediate spaces some- 

 what granulate ; the clypeus and the frontal area are much more 

 finely rugose. The thorax above is slightly convex and rounded 

 on the sides, very like what it is in P. dives. The pronotum is 

 furnished with two spines in front, directed forwards and out- 

 wards, much longer than in dives, and they are slightly curved. 

 The two metanotal spines are longer and thicker than the pronotal 

 spines, divergent with the ajtical portion curved outwards in form, 

 very like the horns of the chamois. Thorax coarsely irregularly 

 rugose. Node of pedicel ivith two long slender spines whieJt, are 

 disposed in lunate fashion claspiivj Hie base of the abdomen ; between
