REHN AND HEBARD 399 



The song of this very shy and vigorous species is a loud and 

 continuous buzzing. The species is known from but two speci- 

 mens, though others were observed at Homestead, Florida; it is 

 apparently a native of the undergrowth of the pine forests of the 

 extreme southeastern United States.

The present species is one of the most distinctive of the genus 

 known from North America, showing nearer relationship to the 

 peculiar N. velox than to any other species. The size of the males 

 is small and the form slender; the females average distinctly larger 

 and more robust, with abdomen unusually enlarged and ovipositor 

 short and broad, distinctly broadest meso-distad. The insect has 

 a generally more coriaceous appearance than the other 

 species here considered, and the ventral margins of 

 the caudal femora are distinctly darkened beneath 

 each of the spines a distance equal to the length of 

 the spine. The present species, unlike the others here 

 treated, has the external of the ventral margins of the 

 caudal femora bearing on an average more (but smaller Fig. 10 A 

 as in the other species) spines than the internal. N eoc o no-
