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

 der boards covering an old well 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 (Rhaph. cavernarum Sauss; Had. svbterraneus 

 Scudd.), which inhabits the Mammoth Cave of Kentucky. I 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, from the Smithsonian Institution, collected by Miss 

 Helen Jennison at Monticello, Mississippi. 



Aegipan (Alyfcav) nov. gen. 



Slender, with long appendages. Head not very large nor full, the 

 front nearly flat, the sides somewhat compressed, the posterior border 

 bluntly but distinctly marginate ; fastigium broad posteriorly, nar- 

 rowing anteriorly, moderately prominent, with a distinct fusiform 

 sulcation; eyes vertically obovate, twice as long as broad, prominent; 

 antennae very long and moderately slender, with the basal joint ap- 

 pressed, about twice as long as broad; second, cylindrical, smaller, 

 tapering a little, considerably longer than broad ; third, slender, 

 cylindrical, as long as the first ; the remaining joints subequal ; apical 

 joint of maxillary palpi nearly as long as the third and fourth joints 

 together, thickened at tip and covered sparsely with short erect hairs. 

 Pronotum subselliform, smooth, with a scarcely raised median line, 

 the front border transverse, scarcely produced behind the eyes, the 

 hind border almost rectangular, produced and more or less rounded, 

 the humeral sinus slight; deflected lobes declivant, much longer than 

 broad, barely reaching the lower edge of the epimera, the front and 

 lower borders meeting at rather more than a right angle ; prosternum 

 unarmed ; meso- and metasternum with small rounded posterior lobes. 

 Tegmina long and slender, extending far beyond the end of the
