caroliniana); on June 12 from ironwood (Osirya virginiana); on June 9, 
from red oak (Quercus rubra); on June 17, from hickory. 
Agrilus subcinctus Gory. Mr. H. A. Wenzel informs me that he 
takes this species on the foliage of poison ivy (Rhus toxicodendron), and 
the numbers taken indicate that poison ivy is the host-plant. 
Agrilus lecontei Saund. Breeds in the wood of dead hackberry 
(Celtis occidentalis) in the vicinity of Harrisburg, Pa. 
Agrilus egenus Gory. Breeds in the wood of dead black locust 
(Robinia pseudacacia) in the vicinity of Harrisburg, Pa. 
Agrilus celti n. sp.

Prothorax wider than long, sides not strongly arcuate, hind angles 
rectangular, with a well-defined carina in both sexes; disk convex, median 
impressions light, lateral depressions well-marked, surface transversely 
strigose. Scutellum transversely carinate, surface granulate. Elytra 
sinuate behind the humeri, dilate behind the middle, apices separately 
rounded and serrulate, basal depressions slight; disk depressed, surface 
imbricate-granulate. Body beneath more shining than above, prosternal

Described from a large series of adults reared from dead 
branches of hackberry (Celtis occidentalis), collected at Hum- 
melstown, Pa., by Mr. H. B. Kirk and the author. 
Type male and allotype in author’s collection and, reared 
June 3, from dead hackberry (Celtis occidentalis) branches 
collected at Hummelstown, Pa., by the author. 
This species has been confused with A. egenus in collections, 
and although it is hard to separate the females from those 
of A. egenus, the males may be easily separated by an examina- 
tion of the genitalia.
