pair the longer, each with two setae; anterior pair of lobes a little more widely separated; 
laterad of latter pair of lobes, a tubercle bearing three setae; a long, powerful seta on pleura; 
two setae on either side of median line of sternum. Female cauda (Plate LV, 274) similar, 
but ventral lobes more pointed, slightly exceeding level of dorsal lobes.

Eriocera fultonensis is a rather common but usually local species thruout 
the northeastern United States. The larvae are found in the same situa- 
tions as are described for the other species of the genus, in sand or gravel 
near the margins of usually large streams. On May 30, 19138, larvae were 
found in considerable numbers along the banks of Fall Creek, Ithaca, 
New York, where they occurred in company with numerous larvae and 
pupae of EH. spinosa, a few large tabanid larvae, a small tabanid pupa, 
and the following beetle associates: Bembidion, Schizogenius, Tachys, 
Gastrolobium, and a few others. The pupal duration is seven days (from 
May 31 to June 6, 1913). 
Larva.— Length, 18-26 mm. 
Diameter, 2-2.3 mm. 
Color, pale flesh yellow; anterior segments of body a little darker. 
Body long and slender. Spiracular disk (Plate LIV, 266) with ventral lobes long and slender, 
lateral lobes shorter; ventral lobes at their tips with one or two very elongate blackish hair 
which are from two to three times length of lobes; in addition to these the usual apical fring 
of yellowish hairs not exceeding lobes; near base on outer side a small pencil of hairs; eacl 
ventral lobe with a very delicate capillary black line which expands abruptly at its inne 
end into a brown area, these two areas inclosing between their proximal ends a more or les 
oval pale area (in some specimens the inner ends completely encircling this pale area, whil 
in others the brown lines are not continuous over the disk); lateral lobes shorter, similar] 
fringed with yellow hairs which are longer than lobes; inner face of lobes with a capillary 
black line. Spiracles rounded oval, widely separated. 
Head capsule and mouth parts almost as in Hexatoma megacera and Eriocera longicornis 
as already described; epipharyngeal region (Plate LIV, 268) produced into a hemisphere 
rounded lobe which is densely covered with fine hairs; two large papillae on either side nea 
tip, between them a terminal tuft of long yellow hairs surrounding two long, slender, seti 
erous papillae. Antenna with sensory papillae at tip short, about one-third length cf segmen 
Pupa.—- Length, 14-16 mm. 
Width, d.-s., 1.8-2 mm. 
Depth, d.-v., 2.5-2.7 mm.
