THE CANADIAN ENTOMOLOGIST 165 



brown, grayish pruinose; male hypopygium small, the appendages 

 of the pleurite long and slender. 



Habitat. — California. 



Holotype. — cT, Bair's Ranch, Redwood Creek, Humboldt Co., 

 Cal., June 12, 1903. (H. S. Barber). 



This species is much smaller than the related E. albihirfa 

 Alex., differing , moreover, in the shorter pile and the differently 

 const-ructed male hypopygium. 

 Eriocera rubrinota, new species. 



Coloration of the thoracic dorsum rusty red, remainder of the 

 body, including the basal plates of the ovipositor, dark brown; 

 cell Ml absent. 



Female. — Length 13 mm.; wing 11.5 mm. 



Rostrum very short, brown; palpi dark brown with an indis* 

 tinct grayish bloom and an indistinct median brownish line; ver- 

 tical tubercle low with a deep notch. 



Pronotum and mesonotum deep, rusty red without apparent 

 markings. Pleura dark brown. Halteres dark brown, the ex- 

 treme bases lighter coloured. Legs with the coxae and trochanters 

 dark brown; femora dark brown, yellow at their bases, these pale 

 basal portions narrowest' on the fore legs, broadest on the hind 

 legs; tibice and tarsi dark brown. Wings suffused with brown; 

 veins dark brown. Venation: Sc ending slightly beyond the 

 middle of R2+3; R2+3 a little shorter than R2 alone; cross-vein 

 r inserted on R2, some distance beyond the fork of Ri+z; b^sal 

 deflection of Cm just beyond the fork of M. 



Abdomen dark, shiny, blackish brown, including the basal 

 portions of the ovipositor. 



Holotype. — 9 , in the collection of Kansas University, labeled 

 "No. 40" without locality, but almost certainly from' Western 

 America, along with the other Williston material in the collec- 

 tion. 



This species is abundantly different from all the forms de- 

 scribed from the New World. It comes in the group with E. 

 fuliginosa O. S., E. tristis Alex., etc., but is readily separated from 

 them by the coloration of the mesonotum and the colour and 

 structure of the ovipositor.
