Vol. XI] COLE AND LOVETT—LIST OF OREGON DIPTERA 249 



specimens of what we take to be this species were collected 

 at Hood River; some are quite small. The wings are in- 

 fuscated and the anal angle much reduced. The male has 

 traces of golden tomentum above, and perfect specimens of 

 females are nearly covered above with these scales as in E. 

 lotus. This species is usually much smaller than lotus, but is 

 very near it. 



290. Eclimus magnus (O. S.) 

 Forest Grove, VI-3 to VI- 18 (Cole and Lane) ; Joseph. 

 Allotype described, 1919, Proc. Cal. Acad. Sci. Ser. 4, IX, 

 p. 225. 



291. Eclimus marginatus (O. S.) 

 Hood River, VI-2 to VI-24 (Cole). 



292. Eclimus muricatus (O. S.) 

 Hood River, VI- 12 (Cole) ; Dee and Parkdale in June 

 (Cole and Childs) ; Grant Co. This big black species was 

 collected on old burned logs. 



293. Eclimus sodalis Will. 

 Mosier, VI- 14 and Dee, VI- 17 (Cole). Three female 

 specimens agree very well with the description of this species. 

 One specimen from Mt. Jefferson, VIII-1 (Lovett), has 

 the pile of the occiput whitish and not yellowish; halteres 

 with a blackish knob ; pile of thorax, pleura and pectus white. 

 The base of the third antennal joint is rather broad. 



294. Epacmus sp. 

 Mosier, VI-14 (Cole). A single female of an unde- 

 scribed species was taken on the same day with the new 

 species described below. It is a very distinct species, but 

 until the male is collected it will not be described. 



295. Epacmus nitidus Cole, new species 



Male : Length 6 mm. Black, with yellow tomentum and 



pile. The occiput and cheeks dull grayish black with some 



yellowish and white tomentum and short yellow pile above
