REVISION OF THE GENUS PHLOEOSINUS—BLACKMAN 449 
elevated on posterior half of disk; hairs short and fine, but notably 
longer than in sequotae. 
Klytra slightly wider than pronotum, about 1.34 times as long as 
wide; sides subparallel on anterior two-thirds, very broadly rounded 
behind; suriace shining; striae narrow, rather strongly impressed, 
with strial punctures fine and rather close; interspaces wide, convex, 
strongly granulate-punctate and rugose, the granules both coarser 
and more numerous than in seguotae, confused, with little evidence 
of uniscriate arrangement on disk; hairs on disk smal] and rather 
short, but not minute as in sequoiaec. Declivity (pl. 40, fig. 21) steep, 
brightly shining, first interspace weakly convex, without serrations, 
with a few small punctures bearing minute hairs; second interspace 
nearly flat, brightly shining, narrowed posteriorly and cbsolete 
on apical sixth, without serrations and with a few minute punc- 
ture-bearing minute hairs; third interspace strongly elevated, with 
coarse, black serrations, often as coarse as in sequozae but sometimes 
considerably smaller; fifth and seventh interspaces each with three 
to five moderately coarse serrations. Mesosternum somewhat oblique 
anteriorly. 
Female.—Similar to male in habitus; frontal rectangle about 0.69 
as long as wide; convex, impressed on a triangular area between eyes, 
with a rather weak median carina on lower half, slightly stronger 
than in male, surface shining, strongly granulate-punctate throughout, 
hairs much stouter and longer than in female of scquoiae; elytral 
declivity (pl. 40, figs. 20, 20a) with first interspace mederately con- 
vex, surface shining, densely, finely punctured, with a few granule- 
like, fine serrations (or often lacking these); second interspace flat, 
stig 
nearly obsolete at apex, finely, densely punctured, without serrations; 
third interspace strongly elevated, with a row of rather large, black 
serrations, with its sides finely, rather closely punctured; lateral in- 
terspaces with a few small to medium-sized serrations on each, and 
each with fine punctures, sparser than on the first three interspaces; 
surface of first three interspaces clothed with numerous flat, scale- 
like hairs, lateral interspaces with much sparser but similar scales 
and with a few moderately short, bristlelike hairs, 
This species is closely related to seguoiae but is easily separated 
on the basis of a number of characters mentioned in the description. 
It averages slightly smaller than sequoiae and is slightly steuter. 
The frons shows constant small differences, but perhaps the most 
readily seen characters have to do with the vestiture of head, pro- 
notum, and elytra, which in seqguotae is usually minute, while in 
squamosus it is both longer and stouter. The declivital vestiture 
in the female is particularly useful, for in sguamosus this is abundant
