Description. Larva. (Plate TV., Fig. 3.)—Length 5 to 6 mm., 
width slightly less than 2 mm. Elongate, oblong, depressed, sides 
nearly parallel; general color brownish testaceous, surface mi¬ 
nutely granulate, the more exposed portions above and below 
finely punctate; covered with dense short grayish pubescence ex¬ 
cept the head and the greater part of the first and last segments, 
which are smooth. Twelve distinct segments besides the head. 
Head four fifths as wide as the first thoracic segment, and 
four fifths as long as broad, dark red-brown. Front with two 
sulci arising at the bases of the mandibles, converging slightly 
posteriorly, and united behind by a transverse sulcus. Four 
shallow impressions are grouped about the center of the space 
included by the sulci. The clypeus is indistinctly separated from 
the front, deeply impressed at middle; the labrum transverse, 
concave, elevated at sides, emarginate in front, it and the 
clypeus with a setigerous puncture on each side. The mandibles 
are rather long and not strongly curved, broadly emarginate 
near middle of exterior margin. The maxillary palpi have three 
nearly equal joints, about as long as thick, except the last, 
which is a little longer and slenderer. The maxillary lobe is 
short and thick, the end rounded, fringed with a dense brush of 
short erect hairs. The ligula is small and short, the labial palpi 
small, of two joints, the first short and thick, the second more 
slender, nearly three times as long as thick. The gular sutures, 
mentum, and base of maxillae, are usually outlined in darker 
color. The antennae are four-jointed, the first short and very 
broad at base, the next two about equal in length, the second 
a little longer than thick, the third more slender, the fourth 
subulate, shorter, borne at the upper side of the apex of the 
third, which also bears below this a small accessory article about 
half the length of the fourth. Eyes wanting. 
First thoracic segment reddish brown, with the posterior bor¬ 
der minutely rugose-granulate, extending forwards in a point 
upon the median line; anterior margin narrowly rugose, remain¬ 
ing surface smooth and shining; one half longer than the next 
segment on mesal line; this latter and the following segments, ex¬ 
cept the last, similar in size and vestiture. The surface of the 
abdominal segments is varied by naked impressed lines, finely 
transversely ridged, as follows: a dorsal row of Y-shaped im¬ 
pressions, one at the anterior edge of each segment; a subdorsal 
row of oblique impressions; and a lateral impressed line, inter¬ 
rupted at the sutures. Beneath is a similar pattern of sculpture. 
The spiracles are raised upon short subcylindrical shining 
tubercles. The first pair are at the extreme anterior lateral 
angle of the second thoracic segment. The remaining nine pairs 
are upon the abdominal segments, a little higher upon the 
sides. The first ones are nearer the anterior margin of the seg¬ 
ment, but posteriorly they approach the hind margin, and those
