chionea Alexander, should be isolated from the Eriopteraria where 
now placed and made a separate subtribe, the Chionearia or 
Claduraria, the former name being based on the oldest genus. 
DESCRIPTION OF THE IMMATURE STAGES 
Larva—Length (fully grown), 10-10.5 mm. 
Diameter, 1.2 mm. 
General coloration light vellow throughout. 
Form comparatively short and stout. Integument provided 
with a delicate appressed pubescence; no distinct setae. Abdomi- 
nal segments divided into a narrow basal annulus and a much 
broader posterior annulus, the latter being approximately two and 
one-half times as long as the former; the ventral surface of the 
basal annuli of abdominal segments two to seven with a conspicu- 
ous transverse area of microscopic points arranged in long trans- 
verse rows. 
Spiracular disk entirely destitute of lobes, the spiracles being 
located on the obliquely truncated dorso-caudal surface of the last 
abdominal segment. Spiracles circular, the ring pale, the centers 
dark; spiracles separated from one another by a distance about 
equal to or a little less than the diameter of one. Ventral surface 
of the terminal abdominal segment with a projecting, flattened 
lobe that is provided with a dense brush of short, pale setae, thi 
organ presumably being used for propelling the insect through 
the soil. 
Head entirely retractile. Head-capsule very compact for a 
member of the Eriopterini. Frontal plate broad, only slightly nar- 
rowed behind, the apex obtuse or subtruncate. Labrum-epiphar- 
ynx quadrate, the surface covered with short, dense hairs; on 
either side a stout oval arm or lobe directed cephalad, these arms 
connected by narrow bars, with the frame-work of the head. Men- 
tal bars entirely separate, each bar with two acute teeth on the 
cephalic side immediately before the apex. Antennae two-seg- 
mented, the basal segment short-cylindrical, the terminal segment 
elongate-oval, gradually narrowed to the obtuse apex. Mandibles 
relatively slender, of a herbivorus tyre, the teeth blunt: anical 
point small; two incomplete rows of flattened obtuse denticles 
along the inner face of the mandible, the outermost tooth of each 
row largest, the others gradually smaller, becoming subobsolescent : 
the basal teeth are very tiny, arranged in short combs; proximal 
caudal angle of the mandible produced into a cylindrical chitinized 
bar. Maxillae consisting of simple hairy lobes, 
Pupa—Length, 6.7 mm. 
Width, d.-s., 1.4 mm. 
Depth, d.-v., 1.4 mm.
