is larger, the cheeks much broader, and the first abdominal 

 segment a little shorter and more swollen towards the apex. 

 The apical dorsal segment in capitata is flat, not convex, and 

 has the sides distinctly raised into marginal carinae.

Long. 10-13 mm. 



S . Tery slender. Head rugose ; thorax strongly and closely 

 punctured, median segment punctured-rugose, Antennae rather 

 slender, as long as the head, thorax, and median segment com- 

 bined, of even thickness throughout. Pronotum longer than the 

 scutellum, the sides almost parallel, the anterior margin straight, 

 with acute angles, the posterior margin widely arched. Sides of 

 the head and thorax rather thicky clothed with long white 

 pubescence. Median segment longer than broad, rounded pos- 

 teriorly. A-bdomen slender, shining, very finely punctured ; the 

 basal segment as long as the second and third combined, petiolate, 

 the narrow petiole nearly as long as the slightly swollen apical 

 poi-tion ; second segment broadened from the base, about equal 

 in length to the third, the segments scarcely constricted at the 

 base ; the apical dorsal segment convex, subcarinate in the 

 middle, sparsely punctured, the punctures large, the apical 

 incision shallow, not as deep as its breadth at the apex, Wings 

 reaching to the apex of the fourth dorsal segment ; second and 

 third abscissae of the radius usually about equal in length, the 

 fourth distinctly shorter ; second recurrent nervure received just 

 before one-third from the base of the third cubital cell, curved 

 outwards in the middle.

This corresponds rather closely with the description of Plesia 

 incisa Cam., but in that description the incision of the apical 

 dorsal segment is said to be twice longer than wide, and some of 

 the details of neuration are not quite the same. But the latter 

 character is of little importance in the genus, especially as to the 

 length of the second and third abscissae of the radius. Many 

 variations occur which are not of specific value.
