CERCERIS NOVAR^, Sauss., (PI. X. f. 8, a, b). 



Clypeus flat, slightly convex in the middle ; the apex 

 projecting a little beyond the lateral pieces ; the apex trun- 

 cated, but with the sides rounded. Eyes a little converging 

 beneath. Ocelli not forming a triangle, the anterior being 

 too much in front of the posterior ; the posterior separated 

 from the eyes by a little more than the length of the third 

 antennal joint, and by its length from each other. Front and 

 vertex strongly punctured ; the face and clypeus with 

 shallow punctures. The face, oral region, antennal keel and 

 the orbits to the length of the scape above the base of the 

 antennae; the mandibles, except at theapex,and aspot behind 

 the eye near the top, yellow. The vertex is sparsely pilose. 

 Thoraxmore strongly punctured than the head ; thepunctures 

 larger and wider apart, the pleurae more coarsely punctured 

 than the mesonotum. Trigonal area impunctate, furrowed 

 down the centre, the furrow crenulated. Two marks on the 

 pronotum, a spot on the mesopleura, tegulse, a small mark on 

 the sides of the scutellum, the metanotum and two large 

 oblong marks on the median segment, yellow. Mesopleural 

 furrow, wide, deep. Apex of median segment gradually 

 rounded above, the apical part rather abrupt, and with two 

 deep, shining, somewhat triangular depressions at the 

 extreme apex. Petiole longer than broad, slightly bulging 

 out at the middle, coarsely punctured. The other segments 

 are also strongly punctured. Pygidial area an elongated 

 oval, narrowed at base and apex, the surface irregularly 

 rugose. Hypopygial incision not reaching to the middle 

 of the segment, longer than broad, rather acutely pointed 

 at the apex. The lateral hair fringe dense, golden-fulvous. 

 There is a broad band on the base of the second segment, 

 the whole of the third segment, except a somewhat semi- 

 circular black mark in the middle at the base and a similar 

 amount of black on the fifth, yellow. The legs are yellow,
