Havo biliuealo ; tarsis posticis nigris ; alis hyaliuis, apice fu- 

 mato. cJ • 

 Long. 15 mm. 



JJah. Barrackpore, Bengal {Rothney). 



Antennae rufous, darker lowards the apex, the last joint 

 one half longer than the penultimate. Head densely covered 

 with pubescence, which is very dense and silvery on the 

 clypeus, darker and longer on the top ; the occiput is black, 

 the outer orbits and the eye-incision narrowly lined with 

 yellow. The clypeus is twice longer than broad, is slightly 

 narrowed towards the top, where it is slightly and roundly 

 incised; the antennal tubercle is not very convex, broad, 

 slightly and gradually dilated towards the apex, which is 

 rounded. The eyes are separated from the base of the man- 

 dibles by the length of the second antennal joint. The lower 

 and upper teeth of the mandibles are large and sharply 

 pointed, the middle one shorter and narrower. Thorax 

 densely covered with a silky fulvous pubescence; the base of 

 the mesonotum — the mark dilated in the middle behind — a 

 transverse narrow line on the apex, the extreme base of the 

 median segment, the central furrow (narrow at the top, 

 broader below), and a mark (narrowed gradually behind on 

 eitlier side at the apex) black ; a narrow line on the pronotum, 

 a narrow line on the base of the scutellums, spots at their 

 sides, and two large marks on the median segment (straight 

 on the inner side, rounded on the outer, and narrowed gradually 

 towards the apex) yellow. The pro- and mesothorax are 

 granular, the sides more coarsely than the top ; the median 

 segment obscurely transversely striated ; the metapleurae 

 obliquely striated above, below the furrow sparsely punctured. 

 The hinder tarsi are entirely black, the middle black, white 

 at the base, the anterior yellowish white ; calcaria white. 

 Wings hyaline, the stigma fulvous, the nervures darker; 

 there is a fuscous cloud occupying the greater part of the 

 radial cellule and the upper part of the apical cubital cellules; 

 the apex of the costal cellule is brownish. Abdomen black, 

 the two basal segments rufous; the sides broadly and apex of 

 the basal segment and the apices of the second, third, and 

 Iburth segments yellow ; the petiole below, except for a 

 narrow line in the middle, and the apices of the second and 

 third segments are yellow. 



A distinct species allied to P. maculipennis and P. stigma ; 

 easily known from them by the much longer and narrower 

 clypeus ; it differs also in having a distinctly defined area 

 above the clypeus, bounded by distinct iurrows, and the apex 

 of the clypeus is quite differently formed, it making a semi- 

 circle, while in stigma its sides are straight and oblique.
