PANTOMORUS OF AMERICA NORTH OF MEXICO 13 
ing hind margin of eye, funicular segment 2 considerably longer than 1, often 
nearly twice as long, longer than 3 and 4 together; eye distinctly elliptical. 
Prothorax wider than long (about 7 to 5), sides broadly and subevenly rounded ; 
pronotum with broader white and narrower brownish scales, the white ones 
forming a narrow, median line toward apex and base (rarely complete), a 
curved, often indistinct, stripe beginning opposite elytral interval 3, and a lateral 
stripe which is often incomplete anteriorly, the disk sometimes with small, 
vague, scattered, whitish spots; pronotal setae curved, inclined on disk, more 
nearly erect laterally ; pronotum (with scales removed) irregularly punctate and 
feebly rugo-granulate, median groove feeble or obsolescent. Elytral intervals 
faintly convex, each with about 3 or 4 confused rows of setae, the longer ones 
more abundant on apical declivity, the length of each longer seta equal to or 
greater than the width of the interval; white stripe covering interval 7 through- 
out, about apical two-fifths of interval 6, and basal half or more of interval 
8, the stripe bordered mesad (on striae 5 and 6) by a broken, usually indistinct 
dark line, and bordered laterad (on stria 8) by a narrow, blackish line. Body 
beneath scaly and setose, the setae longer and more nearly erect medially, the 
abdominal scales progressively finer from base to apex, abdominal vestiture 
sparser medially; metasternum a little longer than in peregrinus. Legs with 
abundant, mostly setalike, prostrate and suberect vestiture ; fore tibia with short, 
well separated denticulations; posterior face of hind tibia with a usually distinct 
ridge from base to about middle. 
Described from about 250 specimens, most of them collected at 
Florala, Ala., in July 1937 by P. N. Annand.

Distribution—Untirep States: Florida (Svea, Pensacola); Ala- 
bama (Florala, Monroeton, Elba, Tunnel Springs, Drewry, Nadawah, 
Beatrice, Repton, Mobile) ; Mississippi (Laurel, De Lisle, Moss Point, 
Gulfport) ; Louisiana (New Orleans). Sourn America: Argentina 
(Tucuman); Peru (Lima); Chile (Angol, Concepcion, Santiago, 
Quillota) ; Uruguay (Montevideo, Colonia Suiza). AusTRALIA (New 
South Wales). 
Type—Probably at Stockholm. 
Bosq * gives the following Argentine localities for lewcoloma.: Prov- 
inces of Buenos Aires, Santiago del Estero, Cordoba, San Luis, and 
Salta. Carlos A. Lizer y Trelles, in a letter of October 18, 1937, to 
Avery S. Hoyt, Assistant Chief of the Bureau of Entomology and 
Plant Quarantine, adds the Provinces of Mendoza, Entre Rios, Santa 
Fe, San Juan, and Tucuman, and the Territories of Rio Negro, La 
Pampa, and Chaco, all in Argentina. The species has also been 
reported from Willow Tree, New South Wales, Australia, where it 
was attacking the roots of alfalfa. 
In the United States, dewcoloma, the “white-fringed_ beetle,” was 
first reported from the vicinity of Svea, Fla., the record being based 
on two specimens collected by E. R. Nelson in July 1936 and forwarded 
to Washington for identification by A. N. Tissot. During the follow- 
ing year the species was extremely abundant near Florala, Ala., and 
on July 14 “in a heavily infested cotton field one man collected approx- 
imately 80,000 beetles from one-half acre in 4 hours.” 'The facts that 
no male of the white-fringed beetle could be found in the field, and 
that every one of 2,311 specimens, dissected for sex determination, 
proved to be a female, strongly indicated parthenogenesis, and this 
was later established by H. C. Young, B. A. App, G. D. Green, and
