Long. 14 mm. 



J . Very slender. Antennae as long as the whole insect, 

 33-jointed, third joint short, only halt as long as the fourth ; 

 the whole flagellum clothed with upright hairs, the apical 

 joints not bent at an angle to the rest as is the case in the 

 females of the genus. Clypeus very short ; face closely 

 punctured ; front and vertex shining, with small scattered 

 punctures, an acute tubercle between the antennae. Pro- 

 notum depressed, deeply arched posteriorly, the angles acute, 

 but not produced into spines. Mesouotum finely aud 

 closely punctured on the lateral lobes and on the anterior 

 portion of the median lobe ; the posterior portion of the 

 median lobe reaching broadly to the scutellum and coarsely 

 reticulate, with five distinct longitudinal carinse ; pleune 

 closely punctured. Scuiellum finely punctured, with a 

 transverse smooth groove at the base, which is divided by 

 a carina. Median segment greenish ; the areola not 

 divided from the petiolar area ; no basal area ; the external 

 area well defined ; the petiolar area transversely striated, 

 the remainder of the segment more or less closely punctured ; 

 spiracles elliptical. Abdomm very slender ; first tergite 

 twice as long as the second, whitish at the extreme base, 

 coarsely punctured-rngulose, extending beyond the apex of 

 the trochanters. Second tergite twice as long as broad, 

 coarsely punctured ; the basal angles separated by a groove 

 and forming small elongate-triangular spaces ; the middle 

 of the segment formed into a trapezoidal area bounded by 

 deep grooves ; third tergite longer than broad, the sculpture 

 similar to that of the second tergite, fourth aud fifth tergites 

 subquadrate, more finely punctured, the median area convex, 

 somewhat compressed laterally, making the segment sub- 

 carinate longitudinally in the middle ; the two apical tergites
