Hindwing. — Broadly lanceolate, costa arched at base nearly straight to outer 

 fifth, apex obtusely rounded, termen oblique, straight ; dorsal margin nearly parallel 

 to costa. Eight veins, 5 and 6 short stalked, 7 from upper angle of cell ; I* furcate 

 at base ; between 3 and 7 transverse vein is not tubular. Color bronzy brown, slightly 

 shining, but without the brilliant gold reflections of the forewing ; grayish white above 

 cell ; cilia shining grayish brown. Underside both wings shining golden gray. 



Described from about fifty specimens all taken in Essex County 

 Park, New Jersey, flying about or resting on the leaves and flowerets 

 of dogwood, Cor nu s candidissimus, May 30 to June 15. 



Cotypes, Cat..No. 12,058 U.S.N. M., in Dr. Dietz's and my collec- 

 tions. 



Named in honor of Wm. G. Dietz, M.D., of Hazleton, Pa., who 

 has recently revised the very difficult group to which this species 

 belongs. Dr. Dietz writes me that he believes that this species 

 represents a new and valid genus, but I prefer to leave this for future 

 settlement, which will be aided by the diagnosis and figures. The 

 specimens were all collected on two small clumps of C. candidissimus, 

 flying in the bright sunshine, morning and afternoon; I visited these 

 clumps nearly every week during the summer and made exhaustive 

 efforts to find some clue to the life history, but without success. 



This species is much like P. acerifoliella Fitch but besides the 

 structural differences, the forevvings of latter are brilliant metallic blue, 

 the hindwings are grayer and the head tuft is a deeper, brighter orange.

WILLIS GRANT JOHNSON. 



The untimely death of Professor Johnson at the age of forty-two 

 years removes from our midst an able student of the broader prob- 

 lems of economic entomology. On March 11, 1908, at his home in 

 New York City he succumbed to spinal meningitis. Mr. Johnson was 

 born in 1866 at New Albany, Ohio, and received his earlier collegiate
