scribed by Blatchley. It was collected by Mr. Nathan Banks at 

 Falls Church, Virginia. 



Mr. Currie exhibited a handsome and peculiarly marked lace- 

 wing fly, belonging to the genus Hemerobius and apparently 

 representing a new species. It was collected by Mr. H. S. Bar 

 ber at Little River, Humboldt county, California, on the 3ist of 

 last May. He then presented for publication the two following 

 papers, in the first of which this insect is described : 



NOTES ON SOME HEMEROBIID^ FROM ARIZONA AND 

 CALIFORNIA. 



By ROLI.A P. CURRIE. 



During the spring and summer of 1903, Mr. H. S. Barber 

 visited the western part of Humboldt county, California, in the 

 interest of the U. S. Department of Agriculture, to investigate 

 forest insects and make collections. En route he spent a couple 

 of days at the Grand Canyon of the Colorado river at Bright 

 Angel, where he collected a number of insects. Although not 

 looking especially for Hemerobiids he nevertheless secured a few 

 species five in all from Arizona and California and two of the 

 California ones appear to be new to science. None of the three 

 species obtained at Bright Angel are new to Arizona but are in 

 cluded in Mr. Nathan Banks' recent paper on " Neuropteroid In 

 sects from Arizona," * although not there listed from this partic 

 ular locality.
