Ptomaphagus (Adelops) loedingi Hatch 
Adelops lodingi Hatch 1953:209, pi. 15, fig. 19; type: Shelta Cave, Huntsville, 
Madison Co., Alabama (U. S. Nat. Mus. #43763). 
Ptomaphagus (Adelops) lodingi: Jeannel 1936: 93; 1949: 104. 
A large troglobitic species characterized by the 3rd antennal seg- 
ment being distinctly longer than the 2nd; the 8th segment is sub- 
quadrate; the strigation is superficial but quite distinctly transverse. 
Known from the type locality and Barclay and Simmons Caves, Madi- 
son Co., Alabama; and from Stewart, Tumbling Rock, and Ivey 
Bottom Caves, Jackson Co., Alabama. The two populations of P. 
loedingi are apparently allopatric, one in Madison County and the 
other in Jackson County. They may eventually be proven to be 
subspecifically distinct, although 1 have seen only 7 specimens from 
Jackson County and am reluctant to make a diagnosis on this basis. 
The original spelling of the trivial name is altered in accordance 
with Art. 32 (c) (i) of the International Code of Zoological Nomen- 
clature, adopted by the XV International Congress of Zoology. 
Ptomaphagus (Adelops) fecundus n. sp. 
Length 2. 5-2.9 mm; width 1.3-1.4 mm. Color dark brown, test- 
aceous. Form elongate and slender, narrowing posteriorly. Eyes 
reduced to a very small, pale areola. Antenna slender, elongate, 
attaining the basal 1/3 of elytra when laid back; segment I slightly 
thicker than segments II-V, which are subequal in diameter; segment 
I one and one-half times as long as II; segment II seven-eighths as 
long as III; IV-VII each about 4/5 as long as III; VII subconical, 
1 1/4 times as wide as VI at the apex and 5/8 as wide as long; VIII 
subconical, 1 1/4 times wider than long; IX and X each 1/5 wider 
than long; XI as wide as X but 1/3 longer. Pronotum subequal in 
width to elytra, widest at the base, 2/3 as long as wide; hind angles 
acuminate, less than right, base very shallowly emarginate between the 
hind angles; disc with transverse strigae finely impressed and distinct. 
Elytra elongate, tapering, 2 1/3 times as long as pronotum; apices 
evenly rounded in the male, acuminate in the female with no external 
apical angle; strigae oblique to the suture; sutural angle narrow, its 
depth twice the distance between the apices. Aedeagus large and 
broad, as in P. loedingi. Described on holotype male and allotype 
female (both in American Museum of Natural History) and 94 para- 
types, Caney Hollow Cave, Franklin Co., Tennessee, 9 May 1959 
(T. C. Barr, Jr., leg.). 
Abroad on the wet rock and mud floor among fragments of bat 
guano, the beetles were so numerous that it was difficult to traverse 
the cave without stepping on them. Caney Hollow Cave is located
