K. vric'ujoii (). S., Molophiliis h'lrt'iponi'is (J. S., these larv;t being 
leather common. Also se\'eral of the big white Leptid larva, Chrys- 
opila tlioracica, and many beetles and worms. Examined on June 
30 and found to contain one healthy larva. 
June 1, 1914 — Rich, wet, organic mud taken from along the rail- 
road embankment at Sacandaga Park, N. Y. This yielded a few 
crane-Hy larvae of the tribes Eriopterini, L'nnuophiliui and Tipiiliiii, 
as well as one of Pciithoptcra. It was placed in vial No. 52 and on 
June 30 emerged as an adult male. 
June 9, 1914 — In Simmons' Woods, Gloversville, N. Y., rich 
black mud from along the creek in shaded places was examined and 
yielded a few Erioptcr'nic larvae and one Pcuthoptera. 
The immature stages may be ciescribed as follows: 
Larva 
Length: Fully extended, 10-12 mm.; diameter, 1-L2 mm. 
Color bright chestnut-yellow, the cephalic half richer and deeper 
colored, the thoracic sclerites suffused with brown; the sub-caudal 
enlargement, when expancied, whitish; the skin with silky, sub-irri- 
descent reflections. 
Head-capsule rather broad, the genal plates with the inner ceph- 
alic angles rounded, and the caudal inner angle prociuceci caudad in 
a long point. The labrum is quite similar to that figured for Erio- 
ccra spiHosii (Journ. Ent. and Zool., VI, PI. I, Fig. A, 1914). 
Mandibles of the usual Hexatomine type, long, slender, pointed, in 
a position of rest pointing caudad; the inner margin provided with 
teeth, a double tooth at about mid-length of the organ and a promi- 
nent knob midway between these teeth anci the base of the mandible. 
(See Plate I, Figs. 2, 4, and 6.) 
The caudal end of the body with four lobes, two being lateral 
and two \'entral in position (Plate L Figs. 8 and 9). The lateral 
lobes are provided with a dense fringe of rather short yellow hairs, 
these hairs directed laterad. The ventral lobes are densely clothed 
with long pale hairs which are directed ventrad and a few scattered 
longer filaments; one very long bristle from each ventral lobe, this 
being much longer than the segment which bears it. The stigmal 
disk is almost free from darker markings, a faint brown line extend-
