NORTH AMERICAN BUPRESTID BEETLES 335 



sides slightly expanded behind the coxal cavities, then abruptly nar- 

 rowed to the apex, which is acute. Posterior coxae with the posterior 

 margin nearly transversely truncate, the exterior angle rectangular, 

 and not prolonged. Tibiae slender, straight, and the anterior and 

 middle pairs with a small tooth on inner margin at apex. Posterior 

 tarsi slightly shorter than the tibiae, and the first joint as long as 

 the following three joints united. Tarsal claws similar on all feet, 

 cleft near the middle, the inner tooth broad, much shorter than the 

 outer one, and not turned inward. 



Length, 4.75 mm.; width, 1.125 mm. 



Female. — Unknown. 



Type locality. — Chesapeake Beach, Md. 



Other locality. — Chain Bridge, Va. 



Type and paratypes. — Cat. No. 41017, U.S.N.M. 



Described from three males (one type). Type and one paratype 

 collected at the type locality, July 12, 1918, by Joseph Wrenn and 

 H. S. Barber, and the other paratype collected at Chain Bridge, Va., 

 June 5, 1920, by J. C. Bridwell. 



This species is closely allied to putillus Say, but differs from that 

 species in being more elongate and subcylindrical, the eyes broadly 

 rounded beneath, and the prosternal lobe broadly rounded in front. 



119. AGRILUS PRAEPOLITUS Wickham 



Agrilus praepolitus Wickham, Bull. Mus. Comp. Zoiol., vol. 58. 1914, pp. 

 442-443, pi. 3, fig. 7. 



This fossil species was described from a small specimen collected 

 in the Miocene shales at Florissant, Colo., and so far is the only 

 fossil form of this genus recorded from North America. Wickham 

 states that in comparing it with Agrilus politics, the two forms are 

 so nearly identical, that they can only be separated with difficulty. 

 It is just possible that Agrilus praepolitus infested the willows of 

 the ancient lake shore. Type No. 2485 in the Museum of Compara- 

 tive Zoology (No. 5359, Scudder Collection). 



AGRILUS VIRIDIFRONS LeConte 



Agrilus viridifrons Provancher, Petite Faune Entomologique da Canada, 

 vol. 1, 1877, Les Coleopteres, p. 360. 



This species belongs to the genus Anthaocia, but Provancher has 

 erroneously placed it in the genus Agrilus in the paper listed above. 



AGRILUS FULGIDICOLLIS Dejean 



Agrilus fulgidicollis Dejean, Cat. Coleopt., ed. 2, 1833, p. 82; ed. 3, 1837, 

 p. 93. 



This species was listed by Dejean in his Catalogue from North 

 America, without giving any description, but Kerremans ~ places it 



7 Mem. Soc. Ent. Belg., No. 1, 1892, p. 275.
