a line connecting the anterio.r orbits and an oblique line on each side running 

 from the posterior orbit to the occipital border mesial to the posterior corner 

 of the head. The gular surface has a large black triangular area, broad 

 behind and narrowed in front. The pronotum has two black dots on its 

 upper surface, each in the center of one of its halves. The meso- and epi- 

 notum are black, with three large orange yellow spots on the dorsal surface 

 of the former and a similar spot on the angle of the latter. The petiolar 

 scale is black below and dark brown on its anterior surface above. 



I have described this beautiful little species from a single minor 

 worker, because its coloration is so striking that it can be readily 

 recognized. It is placed in the subgenus Myruiobrachys with some 

 misgivings as it may prove to be a Colobopsis when the worker major 

 is brought to light.
