OF WASHINGTON, VOLUME XVI, 1914 69 



In alniella the posterior end is flattened to a slightly curved line 

 and the mouth deflects to about 90 degrees. These differences are 

 constant in all the specimens that have come under my obser- 

 vation. 



Coleophora querciella Clemens. Dyar List X. A. Lep. No. 6040. 



Palpi white with very fine golden brown dustings on apical segment. 

 Antennal base clothed above with a long projecting tuft; white, inter- 

 marked with golden brown. Antennge white, annulated beyond basal 

 fourth with light brown. Face and head white. Fore-wings white with 

 apical dustings shading from golden brown to black; cilia black on costo- 

 apical portion to silver gray on dorsal margin. Hind-wings and costal 

 cilia of same, argentious with faint golden overtone; dorsal cilia somewhat 

 darker. Abdomen white. Legs white with faint brownish markings; 

 tarsi not annulated. Alar expanse: 12mm. 



Habitat: Falls Church, Virginia. 



Foodplant: Quercus. 



Two adults reared under Hopk. U. S. No. 11135c and 11135d 

 from Iarva3 collected on Quercus prinus and Quercus alba. Moths 

 issued June 21 and 25, 1913. I had considerable misgiving about 

 the identity of the species, as Clemens knew it only in the larval 

 stage and his description of the larval case, while corresponding 

 in nearly all details with the specimens before us, is misleading in 

 one point. He describes the posterior end as "squarely excised," 

 while as a matter of fact it curves inward to a blunt point, similar 

 to C. leucochrysella Clemens. Larval case 9 mm. long. 



THE SPECIES OF PERILAMPID^ OF AMERICA NORTH OF 



MEXICO. 



BY J. C. CRAWFORD, U. S. National Museum. 



The species in this family fall in three genera E it peri lain pus, 

 Perilampus, and Chrysolampus. The species which Ashmead 

 referred to the genus Elatus must be transferred to Chrysolampus 

 since it has only one ring joint and Walker's original description 

 of Elatus characterizes that genus as having two ring joints. 



GENUS EUPERILAMPUS Walker. 



The only species of this genus occurring north of Mexico is E. 

 triangularis Say. E. opacus Ashm. is a Eurytoma, Doctor Ashmead 

 being misled by a piece of extraneous matter which had adhered 

 to the scutellum.
