A small genus (about 12 species) of essentially Neotropical crane- 

 flies. Our local species has a vertical dance over a height of some 

 3 to 4 feet and was aptly termed '""the King of the dancing Tipulids"' 

 by the late Mr. Charles W. Johnson. The insect is common in open 

 Austral woodlands. The early stages are imperfectly knoAvn but are 

 apparently spent in decaying wood.

A small group of Holaretic crane-flies whose specific limits are 

 still poorly understood. In our faunal region, three nominal species 

 are found but the remarkable variation in color strongly indicates 

 tliat the number of valid forms is less than the figure given and it is 

 very possible that but a single species is found within our limits.
