tured, especially at the apex; the latter is raised in the 
middle, this part being bordered by keels; the spiracles are 
bordered behind by a stout curved keel. Gastrocceli wide, 
deep, smooth, striated on the bottom; the latter and the sides 
are black, the segment between them is stoutly and sharply 
striated ; the petiole on the lower side is stoutly keeled, the 
keels bifurcating at the apex.

of the pronotum (except at the base), tubercles, base of 
tegule, sides of scutellum broadly, the lower third of the 
pro- and mesopleurz, two lines on the mesosternum, the 
narrowed base of the first, its apex and the apices of the 
other abdominal segments, yellow. Abdomen blue, rufous 
between the gastroceli. Legs rufo-fulvous, the anterior

Head brown, the vertex in the middle and the orbits on 
the top behind blue; the front and vertex smooth; the 
centre of face strongly punctured, rufous, mixed with blue. 
Clypeus sparsely punctured. Middle of mesonotum strongly 
reticulated ; the centre at the base depressed ; there is a 
smooth longitudinal space on the sides inside the margined 
furrow. Scutellum shining, the basal slope smooth; the 
lower part on the sides widely furrowed; the apical slope 
widely furrowed in the centre, the furrow triangularly 
narrowed at the top and bottom. Postscutellum smooth, its 
centre and sides obscurely keeled. Areola smooth and 
shining; the keels bounding it curve outwardly, then 
diverge outwardly to the sides of the apex of the segment 
confluent with the posterior median area; the basal ares 
large and roundly dilated on the outer side at the apex ; 
they are irregularly striated, smooth on the outer side; 
the rest is strongly transversely striated, the striz runuing 
into reticulations im places; in the central part of the 
apex are two longitudinal keels, forming an area divided 
by keels into three parts. The upper and hinder part of the 
propleure strongly striated. Mesopleure irregularly and 
strongly striated except in the centre behind. Metapleuree 
closely reticulated. The second abdominal segment is
