Pate ee. Ste CONS Hp le. 22 SEL ae OL IS streblicola. 
Euwallacea streblicola, new species. 
Length, female type, 4.15 mm.; oblong-elliptical, dark red-brown; pronotum 
darker, subquadrate, anterior margin truncate, faintly rugose, rugosities extending to 
sides, becoming finer to the middle, posterior dorsal area shining, with a few moder- 
ately coarse punctures, lateral area shining, subalutaceous, sparsely irregularly punc- 
tured; front broad, subopaque, rather coarsely punctured, with rather broad median 
line; elytra slightly narrowed toward base, with lateral area and basal third shining, 
remaining area densely opaque, strize with moderately coarse punctures in distinct 
rows impressed on lateral area and declivity, interspaces with row of punctures on 
shining area changing to row of granules on opaque area, declivity subconvex, densely 
opaque, interspaces with row of granules, apex broadly rounded, posterior lateral 
area acute and sparsely serrate. Pagbilao, Tayabas, P. I., in log of Streblus sp.,

reddish-brown; pronotum slightly broader than long, with sides nearly parallel, apex 
obtusely rounded, rugosities coarse on declivous anterior, and becoming finer toward 
the dorsal area, and extending into the anterior median lateral area, posterior dorsal 
area shining, faintly punctured, lateral area shining, with faint to distinct rugosities 
and punctures toward the base; front broad, subopaque, with coarse and fine impressed 
punctures, with broad median elevated line; elytra shining, striz faintly impressed, 
with closely placed punctures, interspaces fiat, irregularly punctured, interspaces 
1 and 2 with rows of acute granules from base to apex, others with granules from 
middle to vertex, declivity oblique, flattened, with interspaces 1, 2, and 3 armed 
with rows of granules, interspace 2 faintly impressed, strie 1, 2, and 3 distinctly punc- 
tured, the side margins becoming subacute toward apex, which is not obtusely rounded.
