vertical furrow to the apex of tlie sef^raent, the euclosecl space- 

 shining, more sparsely punctured and divided by a medial, longi- 

 tudimil, short groove; abdomen a little longer 1hau the head 

 and thorax united. Bhick, covered all over with a thin hoary 

 pubescence ; a broad line on each side of the face along the inner 

 orbits to a little above the base of the antenna?, a medial line 

 from the anterior ocellus broadening on the clypeus, a spot on each 

 cheek close to the vertex, a spot on each side of the prouotum, 

 the tibiae and basal joints of the tarsi of all the legs above, and two 

 approximate cup-shaped marks at the apex of the basal segment 

 of the abdomen above, yellowish white; abdominal segments 2-4 

 ferruginous red, the 4th shaded with fuscous black ; wings dark 

 fuscous with a purple effulgence. 



S similar, but the antennae ferruginous beneath.

2 c? • Closely allied to and resembling C. pictlventris ; differs 

 in the antennae being inserted comparatively higher up on the 

 front, in the clypeus {6) being subporrect and incised at apex, 

 in the triangular enclosed space at the base of the median segment 

 being punctured, not smooth, and also in this segment wanting 

 the posterior lateral spots so conspicuous in C. pictiventris.

$ . Head from the front very short and broad ; eyes slightly 

 convergent towards the vertex ; clypeus deeply and very broadly 

 emarginate anteriorly : the front above the base of the antennae, 

 the thorax, and basal segment of abdomen very 

 closely and finely punctured, the 2nd and follow- 

 ing abdominal segments lightly punctured, smooth 

 but opaque ; a very fine obscure carina down the 

 front, joiuing the carina between the antennte, 

 which is prominent ; the enclosed space at base 

 of median segment small, longitudinally and 

 finely striate. Black ; the carina above the

 oblong spots placed obliquely on the vertex, a spot on each side 

 of the pronotum, another beneath the wings, the margins of the 

 tegulcE, the scutellum, postscutellum, a spot on each side of the 

 median segment posteriorly, two minute subapical spots above ou 

 the 1st abdominal segment, two on the base of the 2nd, and sub- 

 apical bands on segments 2-5 yellow, the bands ou segments 2-4
