he case
with the eggs of the common species. Soon after the larva hatches from
the egg it finds its way to an asparagus berry, enters it, and feeds
upon the pulp. In due time it leaves the first berry for another one,
and when full growth is attained it deserts its last larval habitation
and enters the earth, where it transforms to pupa and afterward to the
adult beetle. The life cycle does not differ materially from that of the
common species, and there are probably the same or nearly as many
generations developed.

This species is at present distributed throughout the asparagus-growing
country of New Jersey, particularly in the vicinity of the Delaware
River, the whole of Delaware, nearly the entire state of Maryland, the
District of Columbia, the southeastern portion of Pennsylvania bordering
the state line of New Jersey, northeastern Virginia in the vicinity of
the western shore of the Potomac River, Staten Island, and Monroe
County, N. Y., the last mentioned being the most northern locality known
for the species. The mature beetle in life rivals the common asparagus
beetle in beauty, but may be distinguished by its much broader wing
covers and its color. The ground color is orange red, each wing cover is
marked with six black dots, and the knees and a portion of the under
surface of the thorax are also marked with black, as seen in Fig. 45,
_a_. The beetle as it appears on the plant when in fruit very closely
resembles, at a little distance, a ripe asparagus berry. The full-grown
larva is shown in Fig. 45, _b_. It measures, when extended,
three-tenths of an inch, being of about the same proportions as the
larva of the common species, but is readily separable by its ochraceous
orange color. Fig. 45, _c_, shows the second abdominal segment of larva,
and _d_ same of the common asparagus beetle, much enlarged.
_Remedies._--The remedies are those indicated for the common asparagus
beetle, with the possible exception of caustic lime and other measures
that are directed solely against that species, but the habit of the
larva of living within the berry places it for that period beyond the
reach of insecticides. The collection and destruction of the asparagus
berries before ripening might be a solution of the problem, but it is
questionable if recourse to this
