CLASSIFICATION OF THE SUBFAMILY CRYPHALIN, 53 
denser punctures toward anterior margin, and sparsely clothed with fine erect hairs; 
elytra with fine procumbent pubescence not in rows, with sides straight, striz and 
interspacial punctures very fine, completely confused, becoming obsolete on declivity, 
which is opaque, oblique, slightly convex, with strie evident only toward apex, 
entire surface finely granulated, apex subacuminate. Livingston, Guatemala, May 9; 
Barber and Schwarz, collectors. Type, Cat. No. 7633, U. S. National Museum. 
Notre.—The general form suggests that of Coccotrypes. It evidently comes between 
Dryocoetes and Xyleborus, both of which are distinguished from Coccotrypes by pronotal 
and elytral structures. 
Dryocoetoides caracicolai, new species. 
Length, female type, 2.9 mm.; body elliptical, moderately stout, light reddish 
brown, the elytral declivity darker; pronotum declivous, armed, apical margin 
slightly produced, posterior dorsal area shining, very finely punctured, lateral area 
alutaceous, pubescence short, fine, erect; front flat, subopaque, sparsely clothed with 
short erect hairs, finely rugose toward anterior margin; elytra with sides straight to 
middle, basal half shining, with striz and interspaces faintly punctured in approxi- — 
mate rows, posterior half including declivity densely opaque, strial punctures becom- 
ing coarser and in more distinct rows on declivity, declivity oblique, interspaces 
pubescent and with row of granules, interspace 1 faintly elevated, 2 impressed in 
middle, apex subacuminate. Port of Spain, Trinidad; H. waite ee collector. 
Type, No. 7634, U. S. National Museum. 
Note.—No sexual differences have been observed. There is little variation in 
size and character of the four specimens examined. 
Genus COPTOBORUS, new genus. 
Antennal funicle 5-jointed, joint 1 large, broad, and joint 5 much 
broader than 2; club short, broader than long, sides subequally 
rounded, anterior face with two sinuate sutures, posterior face with 
one broadly procurved subapical suture; anterior margin of pro- 
notum faintly rugose; eyes large, elliptical, emarginate. Type of 
genus, Coptoborus emarginatus, new species. 
_I. Antennal club broader than long; elytra strongly narrowed posteriorly and 
declivity strongly oblique.

and declivity not strongly oblique.

(Pl. III, fig. 37.) 
Length, female type, 2.7 mm.; body elongate, reddish brown; pronotum longer than 
broad, sides parallel, apex obtusely rounded, the rugosities fine, confused, posterior 
dorsal area shining, faintly punctured, lateral area subopaque and more distinctly 
punctured; front broad, flat, opaque, rugosely punctured, with a faint median eleva- 
tion; elytra with dorsal area shining, glabrous, strize faintly punctured, in approximate 
rows, interspaces flat, smooth, with sparsely placed, very minute punctures, sides 
with a few long hairs and narrowed from base to apex which is deeply emarginate, 
declivity oblique, broadly impressed, with the third interspace acutely elevated and 
armed with three or four teeth and small granules. Livingston, Guatemala, May 7; 
H. S. Barber, collector. Type, Cat. No. 7636, U. S. National Museum.
