CLASSIFICATION OF THE SUBFAMILY CRYPHALIN, 65 
Xyleborus grenadensis, new species. 
Length, female type, 2.3 mm.; body oblong-elliptical, ferruginous; pronotum with 
sides parallel, not broader than elytra, posterior dorsal and lateral areas smooth and 
shining, dorsal area very faintly punctured; front opaque, broad, irregularly punc- 
tured, with median longitudinal smooth line; elytra with strial punctures coarse, 
striz 1 to 3 impressed, interspaces with sparsely placed, impressed punctures, declivity 
oblique, subconvex, shining, interspaces 1 and 3 slightly elevated, armed with row 
of granules, 2 flat, punctures of strize 1 and 2 evident, posterior lateral margin faintly 
serrate. Grenada, West Indies; H. H. Smith, collector (No. 276). Received from 
W. F. H. Blandiord, with specimen labeled ‘“‘affinis.’”? Type, Cat. No. 7408, U.S. 
National Museum. 
Note.—This species is at once distinguished from affinis by the shining declivity. 
It is nearly allied to X. torquatus, received from Eichhoff, from which it differs in the 
less elongate form, lighter color and finer granules of the declivity, and less coarsely 
punctured front. 
Xyleborus rileyi, new species. 
Length, female type, 2.3 mm.; body oblong-elliptical, dark ferruginous; pronotum 
with sides faintly narrowed toward the base, posterior dorsal and lateral areas shining 
and rather distinctly punctured; front opaque, with faint median line; elytra moder- 
ately shining, with strial punctures very fine, obscure, interspaces flat, faintly and 
sparsely punctured, declivity shining, subconvex, with interspaces scarcely ele- 
vated, interspaces 1 and 3 armed with coarse granules, punctures in striz 1 and 2 
evident, posterior lateral margin smooth. Capron, Fla., April 25; H. G. Hubbard, 
collector. Type, Cat. No. 7409, U. S. National Museum. 
Xyleborus hubbardi, new species. 
Length, female type, 2.45 mm.; body oblong-elliptical, dark ferruginous; pronotum 
elongate, with sides parallel, slightly narrowed toward base, posterior dorsal and 
lateral areas shining, scarcely punctured: front subopaque, with median line; elytra 
shining, with strial punctures distinct on dorsal area but obscure on lateral area, inter- 
spaces smooth, shining, scarcely punctured, declivity subconvex, shining, granules 
of interspaces 1 and 3 moderately coarse, interspace 2 flat, with strial punctures ob- 
scure, posterior lateral margin faintly sparsely serrate. Biscayne Bay, Fla., February 
7; Hubbard and Schwarz collection. Type, Cat. No. 7410, U. S. National Museum. 
Xyleborus schwarzi, new species. 
Length, female type, 2.8 mm.; body elongate-elliptical, ferruginous; pronotum 
elongate, with sides parallel, posterior dorsal and lateral areas shining, scarcely punc- 
tured; front moderately broad, subopaque, with impressed punctures and median 
shining spot; elytra shining, with strial punctures fine, but in distinct rows, inter- 
spaces flat, with approximate rows of punctures, declivity subconvex, shining, inter- 
space 1 with row of moderately coarse granules, 3 with two or three granules, interspace 
2 flat, strial punctures evident, posterior lateral margins not serrate. Key West, Fla., 
April; Hubbard and Schwarz collection (No. 459). Type, Cat. No. 7411, U. S. 
National Museum. 
Xyleborus howardi, new species. 
Length, female type, 2.35 mm.; body oblong-elliptical, dark ferruginous; pronotum 
with sides parallel, posterior dorsal and lateral areas shining, scarcely punctured; 
front flat, subopaque, with median line; elytra shining, with strial punctures moder- 
ately coarse and in distinct rows, interspaces flat, with row of fine punctures, declivity 
convex, moderately steep, shining, interspaces 1 and 3 not elevated but armed with
