dorsal face, two blunt, approximated, parallel lobes directed cephalad; at the base of long 
apical lobes, a shorter, pointed, setiferous lobe, directed laterad and dorsad, bearing on its 
side and near the apex a few setae. Dorsum of segment 8 with four prominent lobes 
surrounding a hollow, these lobes ending in acute tips, the posterior pair directed more dorsad, 
the anterior pair directed more laterad, at the base of the latter a pair of spiracles. Female 
cauda similar but with acidothecae prolonged, bearing on the side prominent lateral lobes 
(Plate XXXII, 141), corresponding to the setiferous lobe of male as described above; 
quadrangle of tubercles on dorsum of segment 8 (Plate XXXII, 138) about as in male, all 
the tubercles ending in chitinized points.

Tribe Hexatomini 
_ The tribe Hexatomini, as here understood, comprises a very extensive 
group of medium-sized crane-flies, made up of the members of the former 
groups Limnophilini and Hexatomini. The more generalized members 
of the group are herbivorous, but the two highest subtribes, Limnophilaria 
and Hexatomaria, are carnivorous in their feeding habits. 
The larvae of the lower divisions have the head capsule massive and 
compact, the mentum chitinized and with the anterior margin toothed, 
and the hypopharynx usually well preserved. The mandibles are not 
formed into long, curved hooks, and the maxillae are of a generalized 
organization. The higher subtribes, Limnophilaria and Hexatomaria, 
have the head capsule long and slender and very much dissected, with 
the constituent plates very narrow and separate. The mentum is very 
reduced or lacking, in some of the Limnophilaria consisting of an articulated 
transverse bar which is grooved with parallel fine striae. In the group 
Ulomorphae and in the Hexatomaria the chitinized mental region is 
nearly, if not quite, lacking, allowing for great distention of this region 
of the head. The mandibles are powerful, curved hooks, bearing a few 
teeth at about midlength. In the group Ulomorphae the mandibles 
are hinged at about midlength, the basal part being deeply grooved on 
the inner face to receive the blade in a position of rest. The maxillae 
have the outer lobe prolonged into an elongate flattened blade which 
extends out of the thoracic orifice when the head is retracted. 
The pupae of the Ularia and the Epiphragmaria have a pair of large 
spiracles on the dorsum of the eighth abdominal segment, indicating a 
close phylogenetic relationship with the Limnobuni. Dactylolabis has
