CHIRONOMID MIDGES OF CALIFORNIA — SUBLETTE 87 



Linda, July 25, 27, 31, 1957. In CDPH: 1 male, 2 miles east, 4 miles 

 north of Manteca, San Joaquin Co., June 3, 1957, G. 



I have examined five specimens, four of them paratypes from the 

 Canadian National Collections, through the kindness of Dr. J. R. 

 Vockeroth, Entomology Research Institute, Canadian Department of 

 Agriculture, Ottawa. He also has sent me notes on the holotype. 

 Measurements for these specimens are: 



Males: Wing length, range 2.52-2.85; mean 2.65 mm. (4); fore leg 

 ratio 0.77-0.85; mean 2.65 (4); antennal ratio, range 2.11-2.22; 

 mean 2.15 (4). 



Female: Wing length 2.26 mm.; fore leg ratio 0.85. 



Material examined in Canadian National Collections: 3 males, 

 paratypes, 1 male, Aylmer, Ont., Aug. 8, 1924, C. H. Curran; 1 male, 

 Aylmer, Ont., Sept. 7, 1924, C. H. Curran; 1 male, Ottawa, Ont., 

 June 31, 1924, C. H. Curran; 1 male, Ottawa, Ont., July 14, 1926, 

 G. S. Walley; 1 female, locality not recorded. 



Measurement data for this species (male) is summarized as follows 

 (those for the Georgia and New York specimens, fide Roback, 1959, 

 p. 123): 



Previous California records: Fallen Leaf, Lake Tahoe, Sept. 13, 

 1915 (USNM), Roback, 1959, p. 123. 



Pentaneura (Ablabesmyia) peleensis (Walley) 



Tanypus peleensis Walley, Canadian Ent., vol. 58, p. 64, 1926. 



Through the courtesy of Dr. J. R. Vockeroth I have examined 

 paratypes of Tanypus peleensis Walley. Dr. Vockeroth also kindly 

 provided me with the notes on the holotype. 



The California material that I am referring to this species differs 

 from the type series by having the scutellum concolorous with the 

 dark reddish-brown vittae and postnotum, and by having the blade 

 of the aedeagus more strongly curved. 



Male: Wing length 3.00 mm.; fore leg ratio 0.76; antennal ratio 

 2.30; fore tibia: tarsals 1+2, 52:52; venarum ratio 0.75; anterolateral 

 bristles 13. 



Female: Wing length 2.59 mm.; venarum ratio 0.87. 



Material examined: In UCD: 1 male, Cobb's P.O., Forest Lake, 

 June 22, 1953, D; 1 female. Pope Valley, Duvall Lake, June 22, 

 1953, D.
