the centre closely and finely striated ; the sides with a few stout 

 striations ; the depressions at its sides wide, shallow, and marked 

 with stout keels ; the base of the median segment in the centre has a 

 rounded slope, deeply depressed in the middle, and bordered with a 

 stout keel round the sides and apex ; the apex is rugose. The supra- 

 median area is slightly wider than long ; the base almost transverse ; 

 the sides at the base oblique ; at the apex more sharply oblique ; the 

 apex bulges roundly inwardly ; the posterior median area is of almost 

 equal width throughout ; the teeth are large, broad ; the base of the 

 segment is strongly punctured ; the supramedian area has a few 

 oblique striations ; the apex strongly transversely striated. The upper 

 part of the propleurae is strongly punctured ; the centre at the base 

 with a few fine oblique striations ; the lower part at the middle and 

 apex with stout, irregular, mostly curved, keels. Mesopleur^e strongly 

 punctured ; the middle with some stout longitudinal striations ; the 

 tubercles large, elongate, leaf-like, roundly narrowed at the base and 

 apex. The base of the metapleurse above finely, the rest coarsely, 

 punctured, the punctures running into reticulations ; in front of the 

 hinder coxje are some stout oblique striations, and in front of these is 

 a stout curved keel. Mesosternum thickly covered with fuscous hair, 

 punctured; the furrows deep, much widened at the apex. Legs stout; 

 the four anterior coxae and trochanters more or less yellowish ; the 

 hinder strongly punctured ; the hinder tarsi spinose. The costa and 

 stigma are luteous ; the nervures darker ; the areolet narrowed at the 

 top, the transverse cubital nervures almost uniting there ; the first is 

 largely bullated at the top ; the second in the centre ; the recurrent 

 nervure is received in the centre of the areolet ; the transverse median 

 nervure is received distinctly in front of the transverse median. Petiole 

 yellowish at the base, the apex shagreened ; the sides at the apex with 

 some large deep punctures. The other segments are closely punctured; 

 blackish down the middle ; the gastrocoeli shallow, closely punctured ; 

 the space between them striated. The sheaths of the ovipositor
