$ maj. Black, covered with a fine, silky, recumbent, shining

 Fig. 119. Camponotus Mo- from the middle portion of the occiput 

 sericeus, g inaj. Thorax. by shallow, rather wide sulcations ; 

 mandibles with 6 teeth ; clypeus 



higher than broad, medially vertically carinate, median lobe very 

 little produced. Thorax elongate, narrow, emarginate at the 

 meso-metanotal suture, the gibbosity of the metanotum remarkably 

 prominent. Node of pedicel very thick, nearly square, convex on 

 both sides ; abdomen very broad and short. 



$ media et min. Much more slender, the head rounded pos- 

 teriorly ; the mandibles with 5 or 6 teeth ; the node of the pedicel 

 in the intermediate form similar to that in the $ maj. ; abdomen 

 longer, not so broad. In the min. the legs are dull castaneous 

 red, and the node of the pedicel is globose.
