type; tips blunt, ending in two large approximated teeth, with a row of smaller lateral teeth 

 extending basad of each; ventral cutting edge with about four such lateral teeth, dorsal edge 

 with one or two much larger teeth; two strong setae near base of scrobe, and two others near 

 tip of mandible; a large brush of hairs at prosthecal region. Maxilla not projecting, with 

 dense brushes of short, stiff hairs and with two short sensory tubercles which are tipped with 

 very elongate setae; palpi stout and chitinized at base, the apex narrowed and pale. 



Pupa. Length, 10-13 mm. 



Width, d.-s., about 1.5 mm. 



Thorax reddish brown to black in color, depending on age of specimen; abdomen dirty 

 whitish with narrow transverse brownish lines, both above and below; pronotal breathing 

 horns dark brown or blackish. 



Form subcylindrical, abdomen slightly depressed. Cephalic crest of two slender tubercles 

 behind, tipped with long setae; another pair of setae between antennal bases. Pronotal 

 breathing horns elongate, transversely ringed, the tips widely and deeply split into two 

 divergent flaps. Prothorax with a prominent median carina. A tubercle in front of each 

 breathing horn, each with about four stout setae. Mesonotum above wing axil with a 

 tubercle bearing throe setae. Wings reaching end of second abdominal segment. Legs 

 reaching end of third abdominal segment, the tarsi ending about on a level or those of fore 

 legs a little longer than those of other two pairs. 



Abdominal segments divided into two annuli, the basal one still further subdivided into 

 annulets; on tergum three annulets, each bearing a transverse row of setiferous tubercles, the 

 setae very long and conspicuous, in some cases the tubercles multisetose, third annulet 

 with two widely separated, slender, elongate tubercles. Posterior annulus with a basal 

 and a terminal transverse 'row of setiferous tubercles. On sternum, four transverse rows of 

 setiferous tubercles on basal ring and two on posterior ring. On pleura, protuberant spiracles. 

 Lateral angles of segment 8 jutting out into stout lobes which are densely studded with 

 setiferous tubercles, on ventral face continued toward median line as a nearly straight row 

 of about eight setiferous tubercles, on dorsum a finger-like lobe on either side: Male cauda 

 (Plate XL, 178) with sternal valves shorter than dorsal lobes, blunt at tips; tergal valves 

 acutely pointed, directed dorsad. Female cauda (Plate XL, 179 and 180) with tergal valves 

 considerably longer than the more slender sternal valves, broad medially, tapering to the 

 broad, blunt tips which terminate in blackened points; two setae on outer margin.

1869 lAmnophila inornata 0. S. Mon. Dipt. N. Amer., part 4, p. 219, 220. 

 Pseudolimnophila inornata is not so common as P. luteipennis but is 

 found in similar situations. The immature stages are spent in rich organic 

 mud. The only specimens that the writer has reared were taken in
