Subtribe Ularia 
The division Ularia includes only the genus Ula. It represents a very 
primitive group of crane-flies, presumably the most generalized of the 
entire tribe. The head capsule of the larva is oval and very massive, 
with the prefrons large and distinct.. The head capsule and its arrange- 
ment of setae is not conspicuously unlike that of the eucephalous families 
of crane-flies, and this group of Tipulidae is presumably not very different 
from the early tipulid ancestors. The mentum is heavily chitinized, not 
completely divided behind, consisting of two plates, one behind the other. 
The outermost plate terminates in three teeth, while the second plate 
furnishes three additional teeth on each side. The hypopharynx is not 
chitinized. The antennae are very small; the basal segment is nearly 
globular, bearing at its tip two blunt, conical papillae. The mandibles 
are slender; the ventral cutting edge has about five narrow teeth; there 
is a distinct brush of hairs at the prosthecal region. The maxillae are 
of a generalized type, with the palpus large, flattened, and disklike. The 
abdomen is provided with six creeping-welts on the ventral surface of the 
segments. The spiracular disk is moderate in size, squarely truncated, 
surrounded by five subequal lobes which are heavily marked with black 
on their inner faces. 
The pupa has the cephalic crest small and provided only with very 
small setae. The pronotal breathing horns are very long, tapering to 
the subacute tips. The abdominal segments have a basal transverse band 
of a shagreened appearance. The dorsal spiracles on the eighth abdominal 
segment are large and distinct. 
The closest relative of the division is apparently the genus Epiphragma 
in the subtribe Epiphragmaria. But this entire group of genera (those 
included in the subtribes Ularia, Epiphragmaria, and Pseudolimnophilaria) 
is not far removed from the tribe Limnobiini.
