106 Notes on the Tenebrionide. [ZOE 
regions immediately adjacent. Common on alkaline flats beneath 
any object upon the ground. Immature individuals while the in- 
teguments are yet soft, ascend small plants in the warm sun during 
the day, undoubtedly to hasten the hardening of the skeleton. 
Cratidus osculans Lec. Common throughout the county. Fre- 
quents ledges and timbered districts. At Coronado they are plen- 
tiful in wood rats’ nests, and about the roots of Rhus integrifolia. 
The species is clothed with moderately long hairs of a pale tawny 
yellow color. 
Cratidus fusctpilosa Casey. Occurs on the summits of the mount- 
ains about Julian. Have found them very abundant in ledges and 
piles of loose rocks. Clothed with long, erect, piceous black hairs. 
Stenolrichus rufipes Lec. Moderately common. Varies greatly 
in size; the male is frequently a mere pigmy, 5.0 mm. in length, 
while the female may be 8.0 mm. long. Found beneath bark, de- 
bris about bushes, etc. 
Cibdelis blaschkii Mann. Inhabits the timbered and mountainous 
districts. Found beneath the bark of trees. 
Adelina lecontet Horn. Not common. Sometimes met with in — 
immense numbers under decaying and fungus-covered bark of dead 
sycamores. A depressed, reddish-ferruginous colored species. 
Ulus latus Blais. Rare. Occurs along the San Diego River. 
Clothed with rather long, moderately slender, recumbent hairs. 
Elliptical in form and strongly convex. 
Ulus crassus Lec. Common. Sometimes exceedingly abundant 
in March along the San Diego River. Oblong-oval in form, clothed 
with short, robust, dense hairs. 
Blapstinus longulus Lec. Occurs under rocks on the mesas 
about San Diego. This species has an elongate, parallel, depressed 
form. The pubescence is short and sparse. The wings are moder- 
ately well developed, extending nearly to the apex of the elytra. 
Blapstinus dilatatus'Lec. Common, but not abundant. Rather 
evenly distributed. Prefers lowlands and timbered districts. Ob- 
long in form, pubescence rather stout, subrecumbent, moderate in 
length. The wings are well developed; flight somewhat labored. 
Blapstinus rufipes Casey. Common everywhere. Frequently 
pruinose Pubescence fine, rather long, very inconspicuous. Wings 
_ rather rudimentary, about two-thirds as long as the elytra.
