closely on the front, where some of llie punctures are longi- 

 tudinally conHuent, more sparsely on the vertex^ the front 

 between the antcnnai deeply emarginate, with a narrow 

 longitudinal sulcus nearly reaching the anterior ocellus. 

 ^Scape shining, finely and rather closely punctured, smooth at 

 the apex. Fror>otum shorter than the median segment, 

 deeply and closely ])unctui-x}d, almost reticulate ; mesonotum 

 very sparsely ])unctured, with two longitudinal sulci on each 

 side;, the scutellum rather more closely punctured, the post- 

 scutellum very finely and closely punctured ; propleurai 

 closely punctured, obscurely obliquely striated posteriorly ; 

 inesopleura3 coarsely punctured. Median segment finely 

 ]»unctured, rugose, with a rather broad sulcus from the base 

 bordered by low carinte, o!)liquely slo))ed posteriorly. Abdo- 

 men shining, sparsely punctured, more closely on the fourth 

 and fifth segments, the apical segment strongly longituditnilly 

 striated. The sides of the median segments closely obliquely 

 striated. The first recurrent nervure is received at the middle 

 of the second cubital cell, the second at two-thirds from the 

 base of the third cubital cell ; the second cubital cell is pro- 

 duced on the cubital nervure towards the base and narrowly 

 truncate at the extremity ; the third cubital cell is half as 

 long again as the second on the ladial nervure; the third 

 transverse cubital nervure is oblique, slightly curved out- 

 w^ardly near the cubital nervure; the radial cell is narrowly 

 separated from the costa and narrowly rounded at the apex. 



Black ; the pubescence very sparse and white, thicker on 

 the legs, which are punctured, tlie spines of the legs wiiite ; 

 the lateral margins of the abdominal segments very narrowly 

 testaceous. W ings hyaline, nervures black.

l>jearest to P. hotlentola, iSauss., and P. copenf^is, Lep., but 

 differs from the former in neuration and tlie colour of the 

 antenna-, from the latter (which is very poorly described) iu 

 the colour of the wings and pubescence.
