white. The condition of the mental teeth is almost as in A. americana, 

 but the outermost of the two large intermediate teeth is a little larger. 

 The larvae were rather frequent in the mud beneath saturated moss.

Subtribe Pedicaria 



The Pedicaria comprise a well-defined division of the tribe Pediciini, 

 including two groups of genera the more generalized Pediciae, with 

 the genera Pedicia, Tricyphona, Ornithodes, and Rhaphidolabina, and 

 the specialized Dicranotae, with the genera Dicranota, Rhaphidolabis, 

 and probably Polyangaeus. 



The genera of the Pedicaria may be divided in the main as follows: 



Larvae 



1. Abdomen without prolegs, but with raised welts on segments 4 to 7, these covered 



with a microscopic scurfiness. (Group Pediciae) 2 



Abdomen with conspicuous cylindrical prolegs on segments 3 to 7, these with circlets 

 of conspicuous chitinized hooklets around their ends Group Dicranotae (p. 906) 



2. Abdominal segments 4 to 7 with raised welts on both dorsal and ventr t.l surfaces; sid^s of 



hypopharynx not parallel, narrowed toward base Rhaphidolabina Alex. (p. 901) 



Abdominal segments 4 to 7 with welts on ventral surface only; sides of hypopharynx 

 subparallel -. 3 



3. Size very large, when fully grown 40 mm. in length; mental plates without a small lateral 



tooth Pedicia Latr. (p. 899) 



Size smaller, when fully grown under 30 mm. in length; mental plates with a small lateral 

 tooth < Tricyphona Zett. (p. 903) 



The writer is unable to separate the genera of the group Dicranotae 

 with the material available, and is inclined to suspect the congenerousness 

 of Rhaphidolabis with Dicranota. The characters given by Malloch 

 (1915-17 b: 217) to separate the two genera do not hold at all in a series. 



It is impossible also to key the pupae with the present knowledge of 

 the group.

 in Europe, one in Japan, and four in North America. Of the last-named,
