One additional male and two females from same lot show 
no difference except that the front of the males has a much 
more distinct elevated line from middle to anterior margin. 
This species and the following belong to the division of 
the genus characterized by a smooth second interspace of the 
elytral declivity of the females. The species of this genus 
infest Juniperus, Cupressus, Chamacyparis, Taxodium, Sequoia, 
and their allies, and, under certain conditions, may be destruc- 
tive. 
Phloeosinus baumanni n. sp. Female type, length 3.5 mm.; body 
stout; prothorax, ventral surface and legs black, elytra more reddish; 
pubescence yellowish, short, dense on front of head and prothorax, sparse 
and in approximate rows on elytra; the declivity clothed with fine, 
short scales. Head, front convex, rugose, with faint impression and 
faint, elevated line from margin to vertex, slightly broken by impression ; 
eyes oblong; antennal club large, oblong, with three oblique broadly 
curved sutures on anterior face and three nearly transverse curved ones 
on the posterior face. Prothorax, one-third broader than long, narrowed 
from base to apex; sides rounded, faintly constricted anteriorly; punctures 
dense, coarser towards sides. Elytra slightly more than twice as long 
as prothorax; base subacute, produced forward, slightly elevated and 
serrate; striae scarcely impressed but with very coarse distinctly sep- 
arated punctures; the interspaces narrow, scarcely elevated but 
roughened with rather coarse transverse rugosities which often extends 
across the striae between the punctures; declivity convex, with inter- ^ 
spaces one and three strongly elevated and closely serrate, the second 
interspace nearly flat and densely subrugosely punctured. 
Male type, length 4. i mm. ; same color and form as female, except 
that the prothorax is narrower anteriorly; the front is narrow, flat or 
subconcave, with median elevated line from middle to anterior margin; 
the elytral interspaces are smoother and the strial punctures more distinct, / 
the declivity steep, with the first interspace broad, flat, shining and 
irregularly punctured, with two or three teeth on the vertex; the first 
stria is distinct, strongly punctured and broadly curved towards the side, 
almost obscuring the second interspace and stria; the third interspace 
is prominently elevated and serrate, with coarse, closely placed teeth.

Fifteen females and nine males in same lot vary in length 
from 3.9 mm. to 4-1 mm.- .average about 4 mm.
