moderately high, and clothed with setae or scales; basal transverse groove 
usually obsolesecent except sometimes toward sides; pronotal vestiture trans- 
versely or somewhat obliquely directed except medially. Scutellum triangular, 
Squamose. Elytron 10-striate, humerus rounded and slightly prominent, basal 
margin not prominent, conjoined elytra widest about middle, basal margin 
broadly and evenly emarginate; elytral setae irregularly triseriate on each. 
interval, of unequal lengths, the longer ones median on each interval. Abdomen 
beneath transversely aciculate, at least latero-basally, intercoxal piece three- 
fourths to seven-ninths as wide as a hind coxa, sternite 3 a little longer than 4, 
the surface of each longitudinally subplanate, sternite 5 short and with a more 
or less distinct groove just behind and paralleling apical margin; metepisternum 
distinct; mesepisternum with a glabrous, polished spot. Fore coxae large; fore 
femur only moderately stout, but stouter and a little longer than the middle 
and hind femora; hind tibia with corbel open or closed, the corbel plate if 
present narrow and not scaly, dorsal comb three-fourths to about as long as 
distal comb (fig. 2, H, Ff). Spermatheca not produced basally (fig. 4, D, E). 
Type of subgenus.—Naupactus leucoloma Boheman. 
A mandibular sulcus such as that of /ewcoloma and peregrinus has 
not been observed in any other species of the Pantomorus-Naupactuc 
complex, though occasionally, as in some specimens of godmani, a 
feeble, incomplete, and more oblique sulcus is present. 
KEY TO SPECIES OF GRAPHOGNATHUS 
Color usually grayish; dorsal setae longer and finer, the longer ones on elytra 
whitish; rostrum in dorsal view scarcely tapering (fig. 1, A), the latero- 
marginal carina rather strong and slightly overhanging side of rostrum; 
vestiture along median line of pronotum directed cephalad; scales on disk 
of elytron longer than broad in general; corbel plate absent (fig. 2, #). 
(1) leucoloma (Boh.) (p. 12). 
Color brownish; dorsal setae shorter and stiffer, some or most of the longer ones 
on elytra brown or blackish; rostrum in dorsal view obviously tapering 
(fig. 1, B), latero-marginal Carina feeble and not overhanging side of 
rostrum; vestiture along posterior half of median line of pronotum directed 
caudad; scales on disk of elytron subcircular in general and more nearly 
covering the surface; a narrow corbel plate present (fig. 2, F).

Length, 8-12 mm. Brownish gray to gray, apical declivity of elytron usually 
paler than disk, the latter sometimes indistinctly variegated with gray and pale 
brown. Scales moderately dense, setae long and conspicuous, elytral seales in 
general broader than those on head and pronotum; elytral setae of unequal 
lengths, the longer ones fine, often somewhat kinky apically in dried specimens 
and two or three times as long as the shorter ones, the latter brown to whitish; 
elytral puncture rows, at low magnifications, appearing as narrow, dark lines. 
Vestiture on head and rostrum brownish in general, white above and below 
eye and on side of rostrum below scrobe, the scales on subapical area and on 
mandibles very small, often somewhat coppery or greenish, the setae on front 
inclined, those above eye and on rostrum above suberect; nasal plate with its 
posterior margin elevated; median groove much widened anteriorly, the widest 
portion Sometimes about one-fourth width of dorsum of rostrum; scape reach-
