Subtribe Ularia 



Tho 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. Tht) 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. Tho 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 Pseudolimnopliilaria) 

 is not far removed from the tribe Limnobiini.
