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 another species L. pictipennis 

 (Meig.), the type of the genus between wet decaying leaves in bogs. 

 His figure of the head capsule (1883, pi. 1, fig. 10) shows a typical hexa- 

 tomine head (Plate XL VI, 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) \ 



1869 Ulomorpha 0. S. 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 is not uncommon in cool Canadian woods thruout 

 northeastern North America, and the adult flies may be swept from
