NOTES ON THE DIPTEROUS FAMILY CYRTIDiE. 
By F. R. Cole. 
Stanford University, California. 
In 1919 the writer published a revision of the Cyrtidae of 
North America (Trans. American Ent. Soc., XLV, 1-79). 
There are some mistakes and omissions in this paper which 
should be corrected and some notes have accumulated on various 
species of the group. 
Eulonchus marginatus 0. S. There are two specimens of 
this apparently rare species in the collection of the California 
Academy of Sciences, taken at Sobre Vista, Sonoma Co., Cal., 
May 8 (Kusche). 
Ocncea helluo O. S. A specimen taken at College Station, 
Texas, was sent to the writer by Mr. H. J. Reinhard. It is 12.5 
mm. in length and answers the original description in most res- 
pects; it differs in that all the longitudinal veins reach the wing 
margin. In each wing there is an adventitous cross-vein in cell 
M-3, one in cell 1st R-5 in one wing and one in cell R-1 in both 
wings (see fig. 1). 
Acrocera liturata Will. The writer has one specimen taken 
at Los Gatos, Cal., June 20, 1917. This is a female with very 
little black at the base of the scutellum. There is more yellow on 
the abdomen than in the typical description. The species is 
evidently quite variable in coloration. Length 3 mm.
