Nests in hollow twigs. 



Among the workers there is a great deal of variation in the contour 



oi' the node, wliieli, seen from the front, may he only very slightly 



convex, moderately excised, or so deeply that extreme examples might 

 be described as bidentate. The angle at the posterior edge of the 

 epinotum varies too, from very sharp to rounded. In some specimens 

 there is a distinct concavity just in front of the spine. 



The worker minor of laminat us always has the epinotum more 

 projecting behind than in cristatus and the head of the soldier is more 

 Btrongly oblique in front. The latter character is so much like that 

 in Colobopsis that I am sure that the species would have been placed 

 in that subgenus had Mayr received a soldier instead of a worker.

Worker. Length 6.5-7 mm. 



A small series of workers differ from typical laminatus in having the thorax 

 and epinotum entirely black. The gaster is unusually long and slender.

Soldier. Length 9-10 mm. 



Head longer than broad, slightly narrowed in front, sides nearly straight, 

 posterior border very shallow ly concave; anterior portion subtruncate, the 

 truncated portion rounding into the front. Cheeks with a broad and shallow 

 impression that extends beyond the lateral borders of clypcus. Clypeus sub- 

 quadrate, a little longer than broad, with broadly rounded anterior border, the 

 surface flattened. Mandibles rather elongate, blades with 7-8 blunt teeth. 

 Antennae slender, their scapes slightly surpassing occipital corners; funicular 

 joints gradually decreasing in length toward apex, terminal joint distinctly
