 pruinose, last segment red, hypopygium reddish on basal part, black 

 on apical part; legs yellowish, tarsi darker. Wings nearly hyaline,

From Bear Valley, San Bernardino Co., 6700 feet, and 

 Santa Monica, both Cal. (Clark). Type in collection of author. 



Zodion reclusum n. sp. 



Face pale yellowish white; front golden, vertex brown, limited 

 transversely in front, antennae reddish, arista black, third joint about as 

 long as the second; thorax brownish gray, with the fine stripes brown, 

 the submedian very short, the lateral indistinct. Abdomen yellowish 

 gray, with brown marks near middle, leaving a pale median stripe, 

 basal segment gray; legs yellowish, femora usually blackish above. 

 Wings brownish, venation mostly black. Vertex, thorax, abdomen 

 and legs clothed with black hair. Cheeks not one-third the eye-height. 



Length 6.5 mm. 



From Redlands, Cal., Nov. (Cole) and Corvallis, Oregon, 

 (Bridwell). Cotypes in collections of Oregon Agricultural College 

 and that of the author; both males. 



Zodion lativentre Graenicher. 



I do not know this species. A male of what I have called 

 Z. perlongiim was sent Dr. Graenicher for comparison, but he 

 said his species was very different from it. 



Zodion abdominale Say. 



The size is given as smaller than Z. fulvijrons (abitus), and 

 the abdomen pale like the femora. This agrees well with Z. 

 bicolor Adams; moreover, Say's statement about the color of 

 the veins fits this species particularly well. The thoracic marks 

 also agree. 



Zodion triste Bigot. 



Bigot says little of marks on thorax, and I have identified 

 as this species provisionally a form from the West, which is 

 small, has dark legs, and almost unmarked thorax.
