organic mud that is usually covered over with a layer of leaf mold. On 
March 27, 1914, the writer found four large brown eriopterine larvae in 
rich earth from Needham’s Glen, Ithaca, New York. An adult female 
of the present species emerged on April 9. This makes the maximum 
pupal existence less than two weeks, but it is undoubtedly very much 
less than this. 
Larva.— Length, 11.5-11.8 mm. 
Diameter, 1.1-1.2 mm. 
Color a deep reddish or cinnamon brown; incisures of segments paler. 
Form rather stout, body terete. Skin covered with a short, appressed nuhesconem 
Spiracular disk (Plate LXX, 375) squarely truncated, surrounded by five subequal lobes; 
ventral lobes with two parallel dark brown lines which are narrowly united distally, the pale 
stripe between rather broad, distinct, especially near center of disk; lateral lobes with two 
parallel dark brown stripes which are indistinctly connected distally, the space between 
dusky with numerous brown spots; dorsal lobe with an elongate-oval mark inclosing a linear 
yellow center; lobes fringed with long hairs which are longest at tips, shorter toward base, 
and narrowly interrupted between lobes; disk between spiracles unmarked. Spiracles large; 
middle piece and extreme outer margins of ring blackish; spiracles separated by a distance 
about equal to one and one-half times diameter of one. 
Head capsule about as in Molophilus, but ventral bars of capsule not toothed to for 
the characteristic mental plate of that genus. Labrum and epipharynx about as in Molo 
philus. _Hypopharynx broad, flattened, provided with numerous transverse rows of shor 
setae. Antenna short; basal segment stout, cylindrical; apical papilla ‘rather small 
elongate-oval. Mandible (Plate LXX, 374) ending in a rather long apical point, with abou 
four long, flattened teeth along ventral cutting edge, the second from base very small; a short 
recurved hook at prosthecal region and a dense tuft of long yellow hairs in prosthecal slit; 
dorsal appendage at heel of mandible. Maxilla about as in Molophilus. 
Pupa.— Length, 7.5 mm. 
Width, d.-s., 1.2 mm. 
Depth, d.-v., 1.4 mm. 
Head, thorax, and appendages pale yellow; breathing horns yellow; chitinized plates o 
mesonotum dark brown; abdomen brown. (In mature pupae, the sheaths of the appendage 
are probably darker.) 
Cephalic crest (Plate LX XI, 381) low; lateral angles produced into conical, erec 
spinous tubercles, each bearing a stout seta on outer ventral face. Antennal sheaths ver 
angulated, almost serrate. Opposite each segment of antenna on basal half of organ, 
conspicuous blackened tubercle, those at base larger and more conspicuous, the lateral on 
directed outward, above it a second tubercle directed cephalad and simulating a cres 
Antenna extending to just beyond base of wings. Front broad; a blackish area on eith 
side near inner margin of eye, probably indicating point of attachment of tentorium. Labru 
triangular, apex subacute. Labial lobes triangular, tips blunt. Sheaths of maxillary pal 
rather long, narrowed to the slender tip. Pronotal breathing horns short and slender, som
