seventh dorsal segment produced into a flattened plate which is 
narrowly rounded at the apex and closely longitudinally striated ; 
a spine on each side at the apical angles of the sixth ventral segment; 
hypopygium with a blunt spine on each side near the base, thence 
sharply narrowed and elongate to the base of the acute apical spine. 
Black ; base of the mandibles ; clypeus, a V-shaped mark between 
the antennae, the orbits of the eyes narrowly interrupted on the 
summit, a narrow transverse band on the vertex, a broad band on 
tbe posterior margin of the pronotum, the anterior angles of the 
pronotum, tegulae, a large quadrate spot on the mesonotum, a 
vertical band on the inesopleurae, the posterior half of the scutellum 
and a small spot at each of the anterior angles, the postscutellum, 
a broad band narrowed towards the apex on the median segment, a 
transverse band on dorsal abdominal segments 1-6, interrupted in 
the middle on segments 2-5, a transverse band interrupted in the 
middle on ventral segments 2-4, the intermediate and posterior 
coxae beneath and the process of the sternum between the inter¬ 
mediate coxae bright yellow, femora at the apex, tibiae and tarsi 
light reddish brown. Wings hyaline, nervures black, the stigma 
pale testaceous browm. Length 17 mm. 
$. A female from the same locality differs from the type in having 
the ground colour almost black instead of ferruginous.

9. Clypeus raised into a median carina, which broadens at the 
apex and forms a smooth triangular surface. Head very finely 
rugose, a carina from the anterior ocellus to the base of the clypeus, 
the inner orbits of the eyes raised and forming distinct carinae. 
Antennae inserted low down on the sides of the clypeus, much 
further from each other than from the eyes, the flagellum a little 
more than twice as long as the scape. Eyes at the base of the 
clypeus separated by a distance nearly equal to twice the length 
of the scape, on the vertex by less than three-quarters of that 
distance ; the posterior ocelli a little nearer to each other than to 
the eyes. Thorax narrower than the head, very minutely punctured, 
the pronotum depressed, much narrower than the mesonotum, the 
angles reaching the tegulae, mesonotum and scutellum broader than 
long; a well-defined broadly triangular area almost covering the 
dorsal surface of the median segment, rugose and longitudinally
