the base and move narrowly on tlie lower side) yellow. The 

 lower part of the proplenrfe, the greater part of the meso- 

 pleura?, the mesostenuim, and the apex of the nietaplenrre 

 broadly yellow. ]\Iesonotuin punctured, but not very closely 

 or strongly ; the scutellum is less closely punctured ; the 

 postscutellum more closely and distinctly, except at the apex, 

 which is smooth. The areola is irregularly rugosely punc- 

 tured ; the sides at the apex are depresseil and transversely 

 striated; the posterior median area is closely irregularly 

 reticulated ; the outer basal arese are closely and' strongly 

 punctured, the base smooth and the sides striated. Pro- 

 pleurre punctured, but not strongly, the apex striated, more 

 strongly in the middle. Meso- and metapleurje closely punc- 

 tured ; the spiracular area is strongly, closely, obliquely 

 striated. The f( nr anterior legs pale yellow ; the femora 

 broadly lined behind with black ; their tibia have an inter- 

 rupted black line : the lander coxjb are yellow, irregularly 

 and largely marked with black in front and behind ; the 

 femora rufous, with the extreme apex black ; the tibije yellow, 

 with the apical third black. Abdomen black ; the post- 

 petiole, two large apical marks on the second, third, fourth, 

 and fifth segments, and smaller ones on the sides of the sixth 

 and seventh, yellow ; the marks become smaller towards the 

 apex and extend backwards beyond the middle. The petiole 

 is opaque, its sides irregularly transversely striated ; the 

 })ostpetiole is closely longitudinally striated ; the second and 

 third segments are longitudinally striated in the middle ; the 

 gastrocoeli are smooth, with two stout transverse keels on the 

 inner side at the base and two longitudinal ones on the outer 

 side. Wings hyaline, with a slight fulvous tinge ; tiie stigma 

 fuscous, the nervures black. 



This is the largest species of the genua.

Scutellum pyramidal, distinctly raised above the level of 

 the mesonotum ; its basal slope short and rather steep, its 

 jijiical longer and gradual; its sides below the raised part 

 carinate. The depression between the metathorax and median 

 segment is deep, the base of the median segment being raised ; 

 the areola is small, is not defined laterally by keels, and is not 

 d( pressed ; the posterior median becomes gradually wider to 

 the apex, its bounding keel is roundly curved ; there are only 

 two ceiitial and two lateral arese, besides the spiracular. 

 Labium jnojecting; the apex of clypeus transverse. Abdo- 

 men long and narrow, more than twice the length of the
