LIFE HISTORIES OF NORTH AMERICAN GEOMETRIDAE.— LXVIII. 
BY HARRISON G. DYAR, WASHINGTON, D. C. 
Caberodes confusaria Iliihner. Dr. Packard reproduces a figure of Alibot’s as 
the larva of this species (Mon. Geoin., j)l. xiii, fig. 18); but, as appears from the text, 
this is the larva of floridaria Guen., and in any case does not agree with that of con- 
fusaria, having humps, whereas that is smooth. Mr. Bruce mentions (Ent. Amer., 
iii, 47, 1887) that the larvae were swept from clover, but gives no description. The 
present is, therefore, the first account of the larva . 
Egg. Subcylindrical, the micropylar end evenly truncate, the flat area nearly 
as large as the central diameter; other end rounded, the two fliameters nearly ecpial; 
about 20 longitudinal ribs, even, sharp, white crested, stopping at the edge of the 
truncation, slightly beaded; cross-striae fine, obscure; micropylar disk coarsely 
reticulated at the edge, finer centrally. Bluish green, turning to dull red, the ribs 
and reticulations white. Size, .9 X .6 X .5 mm. Hatched in twelve days. 
Stage I. Head rounded, black, slightly shining, epistoma white; width about 
.5 mm. Body moderate, rather stout, the feet normal. Dark vinous brown, banded 
with grayish white; two narrow bands on thorax, between the feet a little irregularly 
edged and confusedly mottled; five alrdominal transverse bands, half as broad as the 
intervening spaces, situated anteriorly on joints 5 to 9, cut by a narrow, thread-like 
subdorsal line, which widens at its posterior junctions with the dark areas; the bands 
are narrowed ventrally and divided by a Irroad adventral and narrow medioventral 
lines. A trace of a dark dorsal line, cutting the white bands anteriorly on the seg- 
ments. Joints 10 to 13 with narrow subdorsal and broad blotchy subventral white 
longitudinal lines. Feet dark, concolorous. 
Stage II. Head quadrate rounded, slightly bilobed, wider than high; vinous 
black, epistoma, antennae and two vertical mottled lines over the lobes white; width, 
.7 mm. Body moderate, feet normal, situated well posteriorly, segments annulate. 
Dark vinous brown; a dorsal row of semi-elliptical white spots, each cut from the 
truncated end by a dark line, on joints 5 to 9; large mottled lateral blotches, partly 
cut liy the subventral fold; slight white mottling subdorsally especially on the tuber- 
cles of joints 2-5 and 10-13; venter dotted on the tubercles. Thoracic feet black; 
anal feet large, dark, with a white outer line. Setae inconspicuous; no humps nor 
elevations. A medioventral white band cut by a longitudinal line and the annulet 
incisures.
