Small differences in sculpture evident in the series are believed to be 
individual variations. 
Type locality —Jalisco, Mexico. 
Host Sambucus sp. 
Type material—Holotype and 175 paratypes, U.S. N. M. No. 55982. 
The holotype and 19 paratypes were taken at the plant quarantine 
station, port of New York, from Sambucus sp. used in crates in several 
shipments from the state of Jalisco, Mexico. More than 150 additional 
paratypes taken from unidentified crate wood in nine other intercep- 
tions are also at hand. 
PITYOPHTHORUS PUDICUS, new species 
Male—Reddish brown, shining; 1.35 mm. long, 2.63 times as long 
as wide. 
Frons convex above, strongly punctured, with median line elevated, 
impunctate, plainly reticulate; transversely impressed below, with 
punctures smaller toward epistoma, with fine, short, inconspicuous 
hairs; median carina fine, sharply elevated. Eye of moderate size, 
with fine facets; about one-third divided by emargination. Antennal 
club with all sutures arcuate, first and second partly septate. 
Pronotum 1.09 times as long as wide, widest behind; posterior out- 
line nearly straight, strongly margined, posterior angles weakly 
rounded; sides evenly arcuate from base to anterior lateral constric- 
tion, rather narrowly rounded in front, with anterior margin bearing 
six small serrations, the middle pair being longer ; dorsal contour nearly 
evenly arched, with summit and transverse impression both very poorly 
developed; anterior area with small, rather wide asperities, more or 
less united at their bases to form incomplete, somewhat irregular, con- 
centric rows, hairs short, fine and inconspicuous; posterior area with 
surface moderately shining, finely reticulate, with rather coarse, deep, 
moderately close punctures on disk, smaller on sides; median line 
rather wide, slightly elevated, impunctate; disk and sides with minute, 
scarcely visible hairs. 
Elytra slightly wider than pronotum, 1.55 times as long as wide, 
1.53 times as long as pronotum; sides subparallel on anterior two- 
thirds, moderately rounded behind; surface brightly shining, finely 
indistinctly reticulate; punctures small, moderately deep, in nearly 
entirely regular rows, only first striae weakly impressed; interspaces 
flat, finely rugulose, impunctate on anterior two-thirds of disk, sides 
similar; anterior disk and sides appearing glabrous, but with minute 
hairs from strial punctures. Declivity moderately abrupt, not sulcate, 
first striae weakly impressed ; interspaces, including suture, not granu- 
late, finely punctured and bearing very fine, rather short, yellowish 
hairs.
