The Illinois collection, separated from the rest of the species’ 
range, is also of special interest because of the unusual nature of the 
habitat. The collector, Dr. J. M. Campbell, has supplied me with 
more detailed data on the locality, and I quote from a letter; “Malt 
trap no. 9 was set in a small stand of Pin, us echinata on a very dry 
site on the S. W. slope near the top of a ridge. There was very little 
litter on the soil ; what little litter there was consisted of pine needles. 
This entire area of S. Illinois is characterized by having very small 
stands of pine scattered on the S. W. slopes of dry, rocky ridges. It 
is possible that any beetles found in this site live in the more mesic 
ravines which are nearby.” 
This species may also exist in Missouri. One female labeled “St. 
Louis, Mo., iv.28” from the Liebeck collection is in the Fall collec- 
tion in the MCZ. The measurements of the specimen fall into the 
range of variation of C. ulkei, but the Illinois record of C. appa- 
lachianus suggests that it might more likely occur in Missouri if we 
accept the accuracy of the specimen label 
Life Cycle Data. Eight adult C. appalachianus , captured Septem- 
ber 1, 1968 in Ellis Cave, Madison Co., Alabama, were kept alive 
in laboratory culture at I5°C in plastic dishes of moist soil from 
Ellis Cave. All adults had died by May 1969. Two beetles becom- 
ing adults in May 1969 died in June and July 1970, suggesting that 
full adult life may be about one year. Copulation occurred in cul- 
ture. A total of 37 eggs were laid on the soil surface, with soil 
crumbs stuck to their sides. The number of females producing these 
eggs is not known. The month of egg laying and number of eggs 
were as follows: October, 10; November, 5; December, 3; January, 
2; March, 14; April, 3. Reproduction may thus occur throughout 
the year, especially under favorable temperature conditions such as in 
caves or deep rock crevices. The eggs were white and oblong, a 
sample of six measured .35-.60 mm (mean .48 mm) by .5 5~-75 mm 
(mean .63 mm). 
A sample of 8 eggs hatched 13 to 20 days (mean 17 days) after 
being laid. A sample of 7 larvae had a total life span in this stage 
of from 26 to 30 days (mean 29 days). The first instar lasted 8 
days for 1 larva. The total number of instars was not determined
