and extending back to seutellum. Dorsomedian and dorsolateral 

 bristles erect, In a single row. Prealar bristles about 4. Halteres 

 white. ScuteUum with 2 transverse rows of erect bristles. Wings 

 distinctly spotted similar to P. pardus Townes and P. parntm Townes 

 but with a disconnected spot in cell Oui. Femora dark brown with a 

 conspicuous preapical white annulus: remainder of legs lighter brown, 

 the tibiae with bases somewhat darker. 



Wing length 2.0, 1.89 mm. (2)j leg ratio 1.6 (1); antennal ratio 

 1.12 (slide) (1). 



Abdomen with incisures marked by a very thin band of lighter 

 color; conspicuously pilose. 



Genitalia similar to pardus Townes but with the ninth teigito 

 narrower and more elongate. 



Material examined: In UCLA: 2 males, Resting Springs, May 30, 

 1955. 



Polypedilum (Polypedilum) califoniieum, new species 



Figure l,d 



Holotype male: USXM 64711, Saratoga Springs, Death Valley, 

 May 27, 1955. 



Head, thorax, and abdomen blackish brown. Dorsomedial and 

 dorsolateral bristles erect, conspicuous, in a single row. Habere 

 knob black, pedicel somewhat paler. Wings pale; anal angle obtuse, 

 correlated with small size; wing margin fringe quite long. Legs 

 beyond coxae infuseate stramineous. 



Wing length, 1.33 mm.; fore tarsi missing; antennal ratio 0.76 

 Cslide). 



Genitalia near jloridense Townes but superior and inferior append- 

 ages not apically narrowed. Inferior appendage shows reduction of 

 bristles to 4 as in jloridt use Townes (5 in paratype). 



Paratype males: In UCLA and USXM: 2 males collected with type. 

 Prealar bristles apparently 4. 



Wing length, range 1.18-1.33; mean 1.27 mm. (4); leg ratio 1.66, 

 1.62 (2); antennal ratio 0.78 (2). 



This species may be distinguished from P. jloridensc Townes by the 

 male genitalia which has the anal point less truncate and the superior 

 and inferior appendages scarcely narrowed apically. 



Polypedilum (Polypedilum) subcultellatum, new speeies
