INSECTS OF MICRONESIA Coleoptera: Platypodidaeand Scolytidae'

Ins ects of Micron esia-Vol . 18, No.1 , 1960
uniform size; vestitur e consisting of sparse, inconspicuous long hair at sides and in front.
Elytra 1.6 times as long as wide; sides almost straight and subpar allel on basal twothirds,
narrowly rounded behind; striae not impre ssed, punctures rather large, deep, very
close ; inter striae as wide as striae , punctures fine, not close, except rather coarse on
inter spaces 1 and 3 (perhaps ail irregularit y ) . Declivity rath er steep, weakly convex, appearing
flattened; lateral margin from interspace 7 to apex rather sharply elevated; striae
somewhat impressed, interspaces appearing feebly convex, interstrial punctures subgranulate.
Vestiture abraded, apparently hairli ke on disc and bristlelike on declivity.
Male: Not available .
DISTRIBUTIO N : Philippine, Solomon, and Palau Is.
PALAU. BABELTHUAP: One, Ulimang, Dec. 1947, Dybas.
This species is readily distinguished from other Micronesian representatives
of the genus by the sharp elevation extending from inter space 7 at the
base of the declivity to the elytral apex. .
Eggers' type and a series from the Solomon Islands (Guadalcanal) were
also studied.
37. Poecilips variabilis (Beeson).
Thamnurqides variabilis Beeson, 1939, Indian Fore st Rec. 5 : 286.
Poecilips niger Schedl, 1939, Federated Malay States Mus., Jour. 18: 345.
-Browne, 1949, Ann. Mag . Nat. Hist. XII , 1: 897.
Female: Length 1.6-2.0 mm., 2.3 times as long as wide; color brown.
Frons weakly convex, surface reticulate and finely punctate; vestiture inconspicuous.
Eye rather shallowly emarginat e, Ant ennal funicle five-segmented ; club obliquely truncate .
Pronotum 1.07 times as long as wide, widest behind center, sides moderately arcuate,
converging on anterior half, rather broadly rounded in front ; surface irregularly reticulate ,
moderatel y shining, rather finely and irregularly punctured , anterior margin with a few
punctures almost imperceptibly subgra nulate ; vestiture consisting of inconspicuous, spar se,
long hair.
Elytra 1.5 times as long as wide ; sides straight and subparallel on basal two-thirds ,
rather narrowly rounded behind; striae not impressed, punctures rather large , distinct but
not deep, close ; inter stri ae as wide as striae, puncture s fine, not close. Declivity convex,
rather steep ; lateral margin rounded ; striae weakly impressed on upper half. Vestiture
consisting of erect interstrial setae, hairlike on disc, rath er stout, and usually with tips
laterall y compressed on declivity.
M ale: The only recognizable male slightly smaller than females, but similar in all other
respects.
DISTRIBUTIO N: Indo-Mala yan area and Caroline Is.
YAP . GAGIL-ToMIL: One, T amil District , Berlese funnel, July-Aug. 1950,
Goss.
PONAPE . One, Nanwei , Aug. 1950, Adams; two, Mt. Temwetemwensekir,
150-300 m., under dead bark , Feb. 1948, Dybas; one, Nanipil , Net District,
Feb . 1948, Dybas.
This species is readily distinguished from other Micronesian representatives
of the genus by the complete absence of pronotal asperities, by the subreticulate
surface of the pronotum, and by the rounded lateral margins of th e
declivity.
