it differs somewhat in the shape of the epinotum, which approxi- 

 mates to that of C. macalatus, having the declivity very oblique 

 and merging gradually into the dorsum. The latter is however, 

 different from that of maculatus, in that it is not compressed laterally 

 and not ridge-like or cristate above.

9|, 15 mm. Head ferruginous (burnt sienna), an indistinct patch 

 on the middle of the vertex, the cheeks and the anterior half in 

 front of the eyes, dark brown or black. The inner edge of these 

 dark lateral areas forms a straight line stretching from the anterior 

 ends of the frontal carinae to the anterior margin of the eyes. 

 Mandibles and basal two-thirds of the scapes dark castaneous, the 

 apical third of the scapes black, the flagellum ferruginous. Thorax 

 and petiole ferruginous, but a little paler than the head. Abdomen 

 brownish black, the base and basal half of the sides of the 1st 

 segment and a small and very diffuse spot on each side of the 2nd 

 and 3rd segments dark ochreous, the apical margins of all the 

 segments testaceous. Legs reddish ochreous, becoming gradually darker 

 towards their apices. A very short and inconspicuous pubescence 

 on the legs and antennae, abundant only on the flagellum, absent 

 from the thorax and abdomen, on the cheeks sparse and inserted 

 in shallow foveae. Pilosity short and sparse, yellowish, present only 

 on the clypeus, meso- and epinotum, scale and apical margins of 

 the abdominal segments. Tibiae cylindrical, strongly setose below; 

 posterior metatarsi with two dense rows of subspatulate hairs on 

 their lower surfaces, (this character occurs in several species of 

 Camponotus). Moderately shining, the abdomen more so than the 

 rest of the body. Sculpture like that of C. maculatus, but the head 

 is also sparsely and shallowly punctured, the punctures pubescent. 

 Mandibles with 5 acute teeth, finely striolate and strongly punctured ; 

 the basal margin much longer than in any of the Myrmoturba group, 

 being almost as long as the masticatory margin. Head quadrate, 

 barely longer than wide, the sides feebly convex, the posterior 

 margin straight, the posterior angles narrowly rounded, as wide 

 in front as behind, except the anterior 7th, which is a little narrower. 

 Median area of clypeus arcuately produced in front but not lobed, 

 the anterior margin crenulate, almost twice as wide in front as 

 long. Frontal area small, triangular and well defined. Frontal
