THE CRANE-FLIES OF NEw YorkK — Part II 833 
pharynx a broad semicircular band of chitin whose anterior margin is provided with 
about a dozen teeth, the intermediate ones more blunt and rounded, the lateral teeth longer 
and more slender. (The antennae of this species were not distinguishable in the specimens 
available, but are undoubtedly similar to those of R. flavipes described hereinafter.) Mandible 
(Plate XX XI, 135) of the generalized limnobiine type, short and stout, terminating in two 
blunt teeth; ventral cutting edge with about three teeth which are gradually smaller toward 
base of mandible; a dorsal row of two teeth, of which the basal one is the smaller; base of 
mandible on outer face (heel) prolonged into an acute flattened blade; a conspicuous tuft 
of hairs at prosthecal region. Mazxilla consisting of two rather short, stout lobes which 
are shorter than the mandible, densely provided with short hairs; palpi large, shaped like 
a half of a short cylinder split lengthwise. 
Pupa.— Very similar to that of R. flavipes, as described on the following pages. (The 
writer has only the cast pupal skin of R. mainensis, and it seems to agree very closely with 
the pupa of R. flavipes except that the lobes of the labial sheaths are longer and more pointed, 
- and the labrum is a little longer to provide for the longer rostrum of the former species.)

Rhamphidia flavipes is a common and widely distributed fly thruout 
the eastern United States and Canada. The species is characteristic 
of cat-tail swamps and similar situations. It has been reared from leaves 
of bur reed, Sparganium, brought in by C. H. Kennedy from Ringwood 
Hollow, near Etna, New York, in September. These larvae were asso- 
ciated with larvae of Prionocera fuscipennis, likewise a characteristic 
inhabitant of open swamps. The specimens here described were taken 
in a small cat-tail swamp near Bool’s hillside, Ithaca, New York, in June, 
1917. Here they were associated with a number of larvae of characteristic 
swamp-inhabiting crane-flies, such as Ptychoptera rufocincta, Pseudolimno- 
phila luteipennis, Limnophila macrocera, Pilaria recondita, Liogma nodi- 
cornis (in moss), Prionocera fuscipennis, and Tipula tricolor. 
This is unquestionably the larva that was found by Hart and doubtfully 
referred by him to the genus Erioptera (Hart, 1898 [1895]:197-199, also 
Malloch, 1915-17 b:237). Later, Mik (1898: 62) doubted that this belonged 
to Erioptera because of the long lashes of hairs surrounding the caudal 
lobes, a character not shown by typical eriopterine larvae. The larvae 
that Hart found were living among rushes and other vegetation floating
