of the same color. The hairs with which the body is very sparsely 
clothed are of two kinds, pointed and truncate, some being pale and 
some dark in color, all being rather short. The head is about half 
as wide as the first thoracic segment and the body gradually widens 
to the third and fourth abdominal segments, and then tapers gradu-

ally toward the anal extremity, and the last segment is rather 
narrow. The segmentation is strongly marked and the tubercles 
on the sides prominent. The legs are long and somewhat slender. » 
The length in somewhat contracted natural position is about 
8.5-9.03 mm. and the greatest width 2.8-3 mm. 
THE PUPA. 
The pupa (fig. 3) is of the usual chrysomelid form, nearly twice as 
long as wide, pale yellowish in color, the head prominent, bent down- 
ward on the thorax, with the legs folded so that 
the tarsi are in a nearly parallel line. The wing- 
pads are rather long and the abdominal segments 
are noticeable for the lateral processes, each of 
which bears a short spine-lke hair. 
The length is 6.5-8 mm. and the width 3.54 mm. 
DISTRIBUTION. 
tic seaboard from Massachusetts to Florida, in 
California near the seacoast, and in the alkaline 
regions of Colorado, Utah, and New Mexico. In 
Fic. 3.—Beet leaf its eastern occurrence it is maritime, being found 
meee much’ very little inland from the States mentioned. 
The distribution is shown in the map, figure 4. 
The maritime origin of the species is evidenced by its occurrence 
in the ‘Kast along the entire Atlantic coast from New England to the 
Gulf of Mexico. It is seldom, if ever, found far inland in that 
region. In the West it occurs in California near the seacoast and 
also in the alkaline regions of Arizona, New Mexico, Colorado, Utah, 
and Montana. In its distribution it resembles Cicindela lepida 
Dej., a white form of tiger beetle inhabiting the alkaline or saline, 
white, sandy soil left by the recession of the sea water which formerly 
covered this region. The writer is inclined to believe that the coastal 
forms are at least subspecies or races and that a third form which 
occurs in Florida, in Kansas, and in southern Texas constitutes still 
another subspecies. 
A single adult of this species was collected at Wichita, Kans., 
April 24, 1917, by Mr. F. M. Wadley, Bureau of Entomology. It is 
of the normally injurious form and it is not improbable that the 
species may have a somewhat general distribution in Kansas, but it
