sliort black liiiir ; the middle lobe raisod and soparatcv] from 

 tlio lateral at the ba?e ; the parapsidal furrows wide at the 

 base and they extend to the middie. Scutellum with scattered 

 punctures, the base oblique ; the keels extend to near the 

 middle. Postscutellum smooth and shining, black, and with 

 a fovea on either side at the base. Median segment closely 

 punctured at the ba.<5e behind the transverse keel ; the rest 

 coarsely rugose, transversely and more coarsely rugose at the 

 apex ; the second transverse keel is less distinct than the 

 first and is bordered on the underside above with fulvous, 

 broadly above, narrowly on the sides. The upper part of 

 the propleurffi closely and deeply punctured, the central part 

 and the lower at the apex strongly irregularly striated ; the 

 extreme base minutely punctured, in the middle beneath is a 

 smooth s})ace. Mesopleuraj closely and rather strongly 

 ])unctured, running into reticulations in the middle. Meta- 

 pleurH3 closely punctured ; the basal depression (h'ep, narrow 

 above, wider below, and with a few stout keels. AJeso- 

 sternum closely punctured ; the middle furrow wide, crenu- 

 lated, the lateral curved, wide and deep, and extending to the 

 middle. Legs rulbus, the posterior deeper in tint; the four 

 anterior coxse and trochanters ])allid yellow, witli a black

 metatarsus and the apex of the last joint black. Wino-s 

 iridescent, with a slight fulvous tinge ; the stigma and 

 nervures are black; the areolet almost square; the trans- 

 verse cubital nervures parallel ; the recurrent ne-vure is 

 received in the nuddle and is largely buUated, as is also the 

 second transverse cubital ; the transverse basal nervure is

Thorax a little more than twice longer than wide. Para- 

 psidal furrows only i caching to the middle. Median segment 

 rugose, the apical slope reticulated, the sides armed with a 

 stout spine; the base has an indistinct keel in the middle. 

 Metapleural keel absent. Head as wide as the thorax ; the 

 eyes reach well back, the space behind them is small and 

 obliquely nairowed. Postpetiole broad, clearly separated.
