July 4, 1911, the cage was again examined and the larve were’ 
found to be about 1} inches long. From early in July to the middle 
of August it became necessary to be away from Govan, where this 
experiment was in progress. On returning, August 16, the root cage 
was examined and two adults found about 6 inches below the surface. 
They were hard and had evidently emerged some days beforé this 
date. When the boards which had been placed over the barrel to 
protect it during the winter were removed in the spring, a number 
of adults was found that had hibernated under this shelter. On the 
above date and at a depth of about 20 inches a very young false 
wireworm (3.5 mm. long) was found; it was pure white and had 
evidently but very recently hatched. This larva was undoubtedly 
the young of one of these accidentally introduced beetles. 
The soil at this time was dry to a depth of 4 inches. On June 25a 
pupa was found in the field, placed in a pill box with dirt, and on the 
30th an adult. Hleodes letcheri vandykei emerged. In the fields, where 
a farmer was plowing his summer-fallow—and it may be remarked 
that this is exceptionally late for working the summer-fallow in this 
country—pupzx were found turned out by the plow. A little flock 
of Brewer’s blackbirds (Euphagus cyanocephalus) were walking in the 
furrow a few yards behind the plow and picking up the upturned 
insects. 
From the middle of July until the grain is harvested adults are to 
be found in large numbers under the grain shocks and bundles as they 
stand ‘in the field, and also under grain sacks. Most of the beetles 
are quite soft early in the season, but later become hard. 

DESCRIPTIONS. 
Eleodes letchert vandykei Blaisd, 
The egg (fig. 23).—The egg is bluntly oval in longitudinal section and circular in cross 
section; it measures 1.1 mm. in length and 0.62 mm. in diameter; it is of a pure glis- 
tening white color and absolutely without sculpturing. Ovarian eggs measured 1.17 
mm. in length and 0.74 mm. in diameter. 
The larva (fig. 24).—Elongate, subcylindrical, con- 
vex dorsally, flattened ventrally. Yellowish, ventral 
surface paler, anterior and posterior margins of first 
thoracic and posterior margins of succeeding segments 
brown; head slightly brown, edge of mandibles black, 
base of mandibles brown; claws, spines on legs, and 
caudal segment dark brown; antennz pale yellow. 
Fig. 23.—False wireworm, Eleodes Anterior and posterior margins of first and posterior 
letcheri vandykei: Egg. Greatly margins of succeeding segments with striate marginal 
enlarged. (Original.) bands; band on anterior margin of first segment 
broader and more coarsely striate. Caudal segment scutelliform, flattened dorsally 
and cu ivex ventrally, bearing 18 stout spines on its margin—4 on each lateral mar- 
gin and J0 on terminal margin; a slight space equal to that occupied by one spine 
separates the lateral from the terminal spines. Several long hairs and a basal row
