of tarsus. Tibial spurs on middle leg subequal, ratio 21:23, slightly 

 shorter than single spur on fore leg; 5 lateral teeth on each spur; 

 hind leg spur ratio 21 :25; comb of 12 bristles. 



Leg proportions:

Abdomen with about 60 to 65 bristles on each side of segment II; 

 apical one-half to one-third of each segment yellowish-white; each 

 with basal black fascia. 



Genitalia with medially projecting "strut" without denticles; 

 distally projecting "strut" almost straight, of moderate length. Dis- 

 tistyle apex almost straight; angle moderately produced. 



I cannot distinguish the female with certainty from that of P. denti- 

 culatus, new species. 



Paratjrpes: In USNM: 2 males, Shafter, Kern Co., June, 1946, 

 B. Brookman; 1 male, Rockwell Pond, Selma, Aug. 4, 1947, W; 1 

 male, Stratford, July 8, 1947, W; 1 male, Huntington Beach, Feb. 21, 

 1950. In UCD: 1 male, Quincy, 4 miles west, Plumas Co., July 16, 

 1949, W. F. Ehrhardt. In UCLA: 3 males, Whitmore Tub, Mono 

 Co., Aug. 3, 1952, McDonald; 1 male, Berkeley, May 1, 1948, W. 

 In CBPH: 1 male, Lake Merced, San Francis Co., Feb. 10, 1959, G; 

 7 males, collected with the holotype; 1 male, Bridgeport, Mono Co., 

 May 15, 1959; 2 males, Pudding-stone Reservoir, Los Angeles Co., 

 June 22, 1952, G; 6 males. Lake Isabella, Kern Co., June 23, 1959, G. 



Males: Wing length, range 2.29-3.11; mean 2.58 (19); fore leg 

 ratio, range 0.66-0.77; mean 0.72 (19); antennal ratio, range 1.57- 

 2.59; mean 2.09 (13); venarum ratio, range 1.40-1.60; mean 1.49 

 (15); middle leg ratio 0.63 (1); hind leg ratio, range 0.64-0.70; mean 

 0.66 (7); tarsal beard length, range 2.50-4.40; mean 3.48 times 

 diameter of tarsus (10). The shape of the angle of the dististyle 

 shows some variation which I have interpreted as differences in 

 mounting techniques. 



This species can be distinguished from other members of the 

 culiciformis group only by the features of the diagnostic male genitalia. 



The species is named for Dr. Paul Freeman of the British Museum 

 (Natural History), whose willing answers to vexing points of nomen- 

 clature and courteous assistance in obtaining named specimens have 

 encouraged me in ni}^ study of the group.
