abdominal vestiture not sparser medially, intercoxal piece about as wide as a 
hind coxa, sternite 3 equal to or a trifle longer than 4, the surface of each 
longitudinally subplanate; metepisternum distinct, elongate; mesepisternum 
without well defined, smooth, polished, glabrous spot. Fore coxae large; corbel 
plate scaly, rather narrow, dorsal comb longer than distal comb (fig. 2, @). 
Spermatheeca slightly produced basally (fig. 4, Ff’).

Type of subgenus.—Naupactus taeniatulus Berg. 
Atrichonotus is similar to Graphognathus in the large fore coxae, 
thick rostrum, thick mandible with feebly prominent support, and 
in the general shape of the eye, prothorax, elytra, and spermatheca. 
Atrichonotus, however, lacks the mandibular sulcus and the con- 
spicuous dorsal setae of Graphognathus, and differs also in the shorter 
second funicular segment, squamose corbel plate, and longer dorsal 
comb, and in the even distribution of vestiture on the abdominal 
sternites.

Artipus texranus Pierce, Ent. Soc. Wash. Proce. 18: 49, 1911. (New synonymy.) 
Length 4.5-6.5 mm. Usually pale brownish gray, some of: the scales with 
a faint cupreous, bluish, or opalescent tinge, flanks of elytra often more or 
less distinctly ochreous, the elytra and pronotum sometimes with irregular, 
blackish vittae, the vittate specimens with scales on dorsum of head and ros- 
trum brown to blackish. Scales small, dense, partially obscuring puncture 
rows on elytra. Dorsal setae prostrate or nearly so except near apex of 
rostrum and of elytron, where they are inclined. 
Rostrum above with median groove narrow and little or not widened apically, 
subapical area not impressed, nasal plate feeble, Scales around eye paler. Pro- 
thorax slightly wider than long, sides usually with a slight emargination very 
near base; pronotum usually without distinct markings, but sometimes with 
three broad, brownish to blackish vittae, surface nearly flat in profile, median 
groove feeble or absent, punctures (with scales removed) fine, shallow, and 
irregularly spaced on disk, the sculpture becoming somewhat rugose laterally. 
Conjoined elytra broadly, feebly emarginate at base, intervals slightly convex, 
color uniform or nearly so in most specimens, but in a few the scales are 
brownish to blackish in a broad, common sutural vitta, and in a sublateral vitta 
which is usually broadest basally and confined chiefly to intervals 5 and 6, the 
vittae extremely variable in width and distinctness, their margins here and 
there more or less deeply indented by the encroachment of patches of pale 
scales, the lateral vittae occasionally much wider than usual, diffuse, and much 
broken, and giving the general surface a variegated appearance; traces of the 
vittae, especially toward base of elytron, present in some Specimens, which are 
otherwise almost uniformly gray. Anterior tibia as a rule with only about five 
slender spines, between which are usually several denticulations; corbel plate 
wider in the larger specimens, narrower in the smaller ones. 
Type locality—Of taeniatulus, Argentina (Buenos Aires and Rio 
Colorado) ; of texanus, Texas (Victoria). 
Distribution—Unirep Sratres: Florida (Pensacola); Alabama 
(Florala, Tuscaloosa); Mississippi (Wiggins, Lucedale, specimen 
from the latter in H. C. Fall collection) ; Texas (Victoria). Soura 
America: Argentina (Buenos Aires, Rio Colorado, San Pedro). 
Tupe.—Ot taeniatulus, location doubtful; of tevanus, a female in 
the United States National Museum, No. 13546. 
The small size, dense sealy coating, absence of erect setae on 
dorsum, and subequal funicular segments 1 and 2 are distinctive fea-
