Notes on the Tenebrionide. 103 
Emmenastus obesus Lec. A small robust species, piceous-black 
in color, and very pruinose while living. Very plentiful about San 
Diego, and generally found beneath dry cow manure, or boards, 
rags, etc. 
Epitragus pruinosus Horn. Young individuals are quite pruinose, 
but on account of the polished surface of the integuments, it soon 
wears away. Not plentiful. Have taken it in my net from Rhus 
Zaurina, also beneath bark at the base of rotten trees. 
Zopherus induratus Casey. Occurs in the mountains about Ju- 
lian, where conifers and oaks are plentiful. The species is black, 
robust and convex, elytra somewhat shining. Length, 16.5 mm.; 
width, 7.0 mm. 
Phileodes diabolicus Lec. An oblong, indurate species, common 
in timbered districts. Have observed the larva and pupa in the 
rotton stumps of Quercus agrifolia. The adult insect feeds upon a 
large and tough species of fungus which grows upon the oak. Once 
I took thirty specimens from one large fungus growing on an oak 
stump. 
Noserus plicatus Lec. Occurs beneath the bark of dead trees, 
in the mountains about Julian. 
Anepsius delicatulus Lec. A small, elongate, apterous species. 
Rather common in maritime districts; have never taken it far from 
the coast, although it is said to occur in semi-desert regions. It 
varies in length from 3.5 mm. to 5.0 mm. 
Nyctoporis carinata Lec. An elongate, rough insect. Elytra 
sculptured with several rows of sharp elevations. Occurs under 
the bark of trees. About San Diego it inhabits the shrubby hill- 
sides, and can be found under the bark or leaves at the roots of the 
plants; also, in the sticks and debris that make up the nest of the 
wood-rat. 
Cryptoglossa verrucosa Lec. An interesting form which occurs 
in the desert region of the county. 
Centrioptera asperata Horn, Rare. Occurs at Poway and is 
nocturnal in its habits. 
Microschatia inequalis Lec. A robust, apterous species. Plen- 
tiful throughout the county. Occurs in spring, beneath boards, 
rocks, etc. Travels about during the day.
