58 Mr. P. Cameron on new 



rufous ; the wings for tlie greater part smoky fuscous ; the 

 stigma and tlie apex of the costa fulvous. ? . 



Long. 17 mm. 



Antennse black ; the basal two joints and the greater part 

 of the third rufous. Head dark rufous ; the front except 

 below^ the vertex except a large semicircular mark behind 

 the ocelli, and the occiput broadly in the centre, black. 

 Front and vertex closely punctured ; the antennal keel stout, 

 longish, and sharpW pointed on the top. The cheeks are 

 closely minutely rugosely punctured ; the face and the centre 

 of the clypeus are shining and distinctly but not closely 

 punctured ; the sides are punctured like the cheeks. Man- 

 dibles black, broadly rufous in the centre at the base. The 

 upper part of the thorax is dark rufous, except the sides of 

 the scutellum and postscutellum, and the area on the median 

 segment, Avhich are black; the pro- and mesopleurjE are 

 black, except above. The thorax is closely and minutely 

 punctured, and is thickly covered with bri<iht pale fuscous 

 pubescence. Legs rufous ; tlie apex of the hinder tibife all 

 round, the apical half on the outer side, and the tarsi black. 

 The wings have the radial and cubital cellules darker coloured 

 than the others. Abdomen black; the petiole, a band, 

 rounded at the apex, on the base of the second segment and 

 a narrow band on the apex of the third rufous. The third 

 and following segments are closely and distinctly punctured; 

 the basal two are less strongly ; the pygidium opaque, irre- 

 gularly reticidated ; the fourth and fifth ventral segments 

 are thickly covered with fuscous pubescence ; the incision 

 on the last segment is nearly as wide as it is long. The 

 sides of the last segment are irregularly largely punctured. 

 The petiole is short, broad at the sides, and nodose. 



The apical margins of the abdominal segments are depressed 

 and smooth. The cheeks are covered densely with a golden 

 pile, as are also the lower inner orbits. The area on the 

 median segment is closely punctured and has a narrow 

 smooth line down the middle. On the lower side of the 

 mesopleurse, near the apex, is a short, rounded, not very 

 proiiiinent, tubercle. The apex of the clypeus is roundly 

 and deeply arched in front. 



Comes near to C. dentata, Cam., but, a2)art from the 

 structural difl'erences, it may be known from it by the 

 great extension of the rufous colour and the absence of 

 yellow markings.
