) species, short, fine, erect or suberect hairs are on the body and appendage surfaces and may be rather abundant. The sculpture apparently consists of extremely fine, dense punctation, often too small to be resolved at magnification upwards of 100 X with the light microscope, and associated with this is often a more or less well-developed, but never obtrusive, fine, short, appressed pubescence. In addition, a coarser but still rather shallow sprinkling of larger round punctures or foveolae is superimposed on the fine pruinose integument; this coarser punctation is probably always present in some form, but is variably distinct in different parts of the body and in different species, and varies also in gauge and density.

Not only is the habitus in general similar in all three castes of the more primitive members of each tribe, but there are also particular characters, for example, the downcurved pygidial spine shared by the males of many species in both tribes and the detailed correspondence of the primitive wing venations, which do not seem readily ascribable to convergent evolution.

The body is stout, but the thoracic and first abdominal somites are drawn out into a slender neck, curving ventrad, much as in the Wheeler's generalized ectatommiform or pachycondyliform body shape.

No single ectatommine species carries all of these primitive character states at once, however, and one has to postulate an archetypical ectatommine that combines all the traits needed to produce something as completely primitive as certain
