Lawrence & Stephan — Cerylonidae 
153 
Distribution. Mountains of northern California and south in the 
Sierra Nevada at least to Mariposa County. 
Biology. The Mather series was sifted from conifer debris to- 
gether with Cerylon calif ornicum. 
Philothermus Occident alis is not very closely related to its eastern 
congeners, as evidenced by the prosternal and mesosternal characters, 
as by the elongate parameres, which arte extremely reduced in both 
puberulus and glabriculus. 
Philothermus puberulus Schwarz 
(Fig. 27) 
Philothermus puberulus Schwarz, 1878: 361. Type locality: Tampa, 
Florida. Holotype, No. 4512 U.S.N.M. 
This species is easily distinguished from P. glabriculus by the 
vestiture of numerous, long, erect hairs and the distinctly crenulate 
lateral pronotal margins. It is also smaller in size (1.6-1.9 mm.) 
and somewhat more elongate, with coarser and denser pronotal punc- 
tation. 
Distribution. Georgia, Florida, and the Greater Antilles. Re- 
ported by Hinton (1936) from Mexico, Guatemala, and Panama. 
Biology. Adults collected under bark of Pinus and in a berlese 
sample from a swamp floor. 
The Neotropical distribution of this species must remain tentative 
until a complete revision is undertaken, since there appears to be a 
complex of tropical species related to P. puberulus. Specimens from 
Cuba, Puerto Rico, and Hispaniola appear to be conspecific with the 
Floridian population, but most of the specimens we have examined 
from Mexico and Central America are not the same species. Horn 
(1878) also reported this species from Arizona, but we have seen no 
specimens to verify this record. 
Cerylcautomus Sen Gupta and Crowson 
Cerylcautomus Sen Gupta and Crowson, 1973: 439-441. Type species, by 
original designation, C. floridensis Sen Gupta and Crowson. 
This genus was based on a single Floridian species and several 
unnamed forms from Jamaica, Hispaniola, Puerto Rico, Trinidad, 
and British Guiana. All members of the genus have at least vaguely 
defined antennal cavities, similar to those in Cautomus, located later- 
ally on the prosternum (not on the hypomera) and defining a median, 
raised, prosternal plate. In addition, the procoxal cavities are open
