16 SOME INSECTS INJURIOUS TO TRUCK CROPS. 
head is comparatively small, of about the same width as length, 
excluding the mouth-parts. : 
The pupa (fig. 3, d).—The pupa is creamy white in color and is 
rather thickly covered with short, stiff bristles, which assist it in loco- 
motion. It is quite active and capable of crawling a considerable 
distance. 
DISTRIBUTION. 
Le Conte’s type and cotypes were from Georgia and Louisiana. 
The species is recorded or has come under the writer’s notice from 
a limited number of localities. These include Ithaca, N. Y. (Chit- 
tenden); New York, N. Y. (Juelich and Roberts); Buffalo, N. Y. 
(Juelich) ; Madison, Gloucester, and Hudson County, N. J. (Smith); 
Four Mile Run, Va. (Pratt); and Washington, D. C. 
INJURY AT FOUR MILE RUN, VIRGINIA. 
When this species was first observed, in the latter part of July, sev- 
eral larve and a single adult were found in the tuberous roots under- 
ground. The trucker on whose farm the injury was committed stated 
that he had observed attack by this species the two years before, 1. e., 
in 1900 and 1901, when it occasioned some loss. The outward mani- 
festations consist in the tops of the parsley beginning to turn yellow, 
then wilting, and finally drying out. When a plant was pulled, the 
roots broke off just below the surface of the ground, frequently dis- 
lodging the larva or grub and leaving others below. September 5, 
when a third visit was paid to the infested locality, injury had 
increased beyond all expectations, nearly half of the crop having been 
destroyed. Asin the previous instance, larve and adults were found, 
as also pupx. It is obvious, therefore, that the single adult found on 
the first occasion was a straggler from the first or hibernated genera- 
tion and the beetles found later were members of the new generation. 
Where the larvee were found attacking small stems—those less than a 
quarter of an inch in diameter—injury was shown quite early and the 
plant was killed. But in older stems from one-half to three-fourths 
of an inch in diameter damage was not so conspicuous. Large tubers 
show excavations on an average of about 1 inch in length and a fourth 
of an inch in diameter. Owing to the soft nature of the roots these 
excavations are decidedly irregular and assume a light reddish-brown 
color. The holes made by the beetles in exit are so large that some- 
times considerable quantities of earth are washed in by rains and 
doubtless assist In promoting decay, leading to the ultimate destruc- 
tion of the plants. Some of the outer roots proceeding from the 
tubers are also penetrated. In one root under examination, con- 
taining two larve, less than one-fourth of the root remains, the rest 
having been destroyed by decay. In 1903 larvee were observed as
