hairs, and each of the four paired lobes has a sensory bristle near the tip. 
The four anal gills are not very prominent. 
_ The head capsule is of the hexatomine type. The mandibles are 
sickle-shaped, with two small, broad, blunt, sawlike teeth just beyond 
midlength. 
Brauer (1883:55) found the larvae of cae species — L. pictipennis 
(Meig.), the type of the genus — between wet decaying leaves in bogs. 
His figure of the head capsule (1883, pl. 1, fig. 10) shows a typical hexa- 
tomine head (Plate XLVI, 213).. Beling (1879:51-52) found this species 
in the sand of a small, dried-out brook bed. 
Group Ulomorphae 
Genus Ulomorpha Osten Sacken (Gr. Ula + shape) % 1 
1869 Ulomorpha O.8. Mon. Dipt. N. Amer., part 4, p. 232. 
Larva.— Form slender. Body covered with a rich golden-yellow pubescence. Spiracular 
disk surrounded by four unequal lobes, the ventral pair the longest, lying subparallel, fringed 
with exceedingly elongate hairs. Spiracles small. Head capsule narrow, the dorsal plate 
narrow, at tip expanded into a spatula. Mandible hinged, blade very long and slender, 
with a single very long lateral tooth at its base. Maxilla densely golden hairy, outer lobe 
projecting, bladelike. Antenna with a very long, tapering, apical papilla. Mentum not 
chitinized. 
Pupa.— Cephalic crest prominent, each lobe with three setae. Pronotal breathing horns 
very long and slender, sinuous, cylindrical, at apex split into two flattened divergent lobes. 
Mesonotum short, very convex, unarmed. Wing sheaths attaining end of second abdominal 
segment. Leg sheaths short, ending before tip of third abdominal segment; hind tarsi 
a little longer than the others. Abdominal segments divided into two rings, posterior ring 
with a subterminal transverse armature of stout black spines and a few long setae; sternal 
armature stronger than that of dorsum. Pleura armed with a few similar spines. Acido- 
thecae of ovipositor very long and slender. Dorsum of segment 8 with a trapezoid of four 
lobes. 
The genus Ulomorpha includes five known species, the genotype, 
Ulomorpha pilosella, of the eastern United States, and four western 
North American species. The immature stages of the genotype are spent 
in rich organic mud in shaded situations. 
Ulomorpha pilosella (O. S.) 
1859 Limnophila pilosella O. 8. Proc. Acad. Nat. Sci. Phila., p. 242. 
Ulomorpha pilosella is not uncommon in cool Canadian woods thruout 
ortheastern North America, and the adult flies may be swept from
