The fungus ( Polyporus volvatus Peck) was collected 7 August 
and sent directly to Washington where five adults and two pupae 
were taken from the material. 
This species is much larger than any other species of Crypto- 
phagus known in this country. Nearly all the North American 
species, except a few little known ones from Alaska, have been 
included in a table of species by Casey, and none measures more 
than 2.9 mm., only three-fourths as long as C. maximus. In 
addition, the species is not as conspicuously pubescent as usual 
in the genus, and has none of the longer, suberect hairs charac- 
teristic of many species of Cryptophagus. There is no species in 
the Casey collection that is closely related to this one. C. 
boulderanus , while large, is quite conspicuously pubescent, and 
C. valens, another large species, is quite unlike it in color and 
pubescence. 
Pharaxonotha zamiae, new species. 
Elongate oblong-oval, shining, castaneous, very inconspicu- 
ously and sparsely pubescent, appearing glabrous except under 
a high magnification, pronotum with impressed line at lateral 
fifth extending from base about one-third length of pronotum. 
Head subtriangular with clypeus anteriorly truncate but as seen 
from above rounded; frons depressed with a depressed line ex- 
tending obliquely to side margin in front of antennal socket; 
eyes large; head coarsely and very densely punctate. Antennae 
about one-fourth length of beetle, club 3-jointed and twice as 
wide as preceding segments, the two segments preceding club 
slightly enlarged. Prothorax transverse, with narrow darker 
margins on all sides; lateral margin arcuate anteriorly and 
posteriorly but nearly straight medially; a deep, margined, lon- 
gitudinal, somewhat curved sulcus on either side at lateral fifth 
extending forward nearly one-third length of pronotum and 
ending abruptly, these sulci connected at base by a transverse 
groove widening considerably in middle of base of pronotum. 
Punctation coarse and dense but not as dense as on head, pu- 
bescence very fine and inconspicuous. Scutellum small, rounded, 
indistinctly punctate. Elytra a little wider than prothorax with
