straight. The female abdomen has at its end a sting while the 
male has three sharp spines. The segments of the fore tarsi in 
the female are flattened somewhat while those of the male are 
cylindrical. Legs of the male have fewer spines and hairs than 
those of the female which present a very bushy appearance. 
The abdomen of the female has six segments and that of the 
male seven. 
GEOGRAPHICAL DISTRIBUTION. 
The insects of this group occur in all the continents of the 
world but are most abundant in tropical regions. There the 
specimens are usually very large and although in the greater 
number of cases the ground color is very dark or black, there are 
spots, bands, etc., of the brighter colors. 
Specimens of this group become more and more rare as the 
climate becomes colder. Apparently the Upper Austral zone 
marks their northern limit with perhaps the exception of 
occasional stragglers into the Transition zone. 
Within the territory this paper attempts to cover, namely 
North America, the species of the subfamily Campsomerinz 
seem to far outnumber those of the Scoliine.
