This insect, found in North Carolina by Mr. H. K. Morrison, un- 

 der boards covering an old Avell about forty feet deep, and on the 

 wooded sides of the same, near the top, is one of the most interest- 

 • ing insects recently discovered in the country, from its close affin- 

 ity to Had. cavernarum (RJiaph. cavernarum Sauss; Had. suhierraneus 

 Scudd.), which inhabits the Mammoth Cave of Kentucky. T shall 

 take an early occasion to discuss the relation of these two species to 

 each other and their allies, and will only mention here that the pres- 

 ent species has several points of structure in which it approaches the 

 allied genus Ceuthophilus. I have before received the species, in 

 poor condition, Irom the Smithsonian Institution, collected by Miss 

 Helen Jennison at Mouticello, TNIississippi.
