NORTH AMERICAN BUPRESTID BEETLES .209 



ciaws dissimilar, anterior and middle claws cleft near the tip, and 

 the teeth nearly equal in length ; posterior claws cleft near the middle, 

 the inner tooth broad, shorter than outer one, and not turned inward. 



Length, 6.5 mm. ; width, 1.35 mm. 



Female. — Differs from the male in having the front of head red- 

 dish cupreous; antennal joints 6 to 11 as wide as long; presternum 

 more sparsely punctured, sometimes transversely rugose, and with- 

 out long, erect pubescence; first abdominal segment not depressed 

 at middle; anterior and middle tibiae armed with an indistinct 

 tooth at apex, and the tarsal claws similar on all feet, cleft near the 

 middle, the inner tooth broad, shorter than outer one, and not 

 turned inward. 



Length, 5.25 mm. ; width, 1.25 mm. 



Eedescribed from the male type and female allotype (Cat. No. 

 21708) in the United States National Museum. 



Type locality. — Gainesville, Florida. 



DISTRIBUTION 



Florida: Gainesville, March 27, 1917 (H. L. Dozier). Archer, March 28 

 (A. Koebele). Enterprise, June 17 (Hubbard and Schwarz). Sanford, 

 May 12 (J. A. Reeves). 



Variations. — No variation worthy of note has been observed in 

 the specimens examined except in size, which varies from 6 to 8 

 millimeters in length. 



Host. — The larval habits are unknown, but since H. L. Dozier 

 collected the adults abundantly on the foliage of ironwood or hop- 

 hornbeam {Ostrya virginianu, (Miller) Koch), it is probably the 

 host plant for the larvae of this species. Under the description of 

 this species the adults were recorded as having been collected on 

 blue beech which was incorrect, but should have been hop-hornbeam. 



This species is rare in collections but Dozier reports it fairly 

 abundant on the foliage of hop-hornbeam. It resembles vittaticollis 

 and audax but is more slender than either of these two species. It 

 also differs from both these species by not having the pygidium 

 carinate, and by having the posterior angles of the pronotum strongly 

 carinate in both sexes, whereas in vittaticollis and audax there is no 

 trace of carinae.

 220, 237-239, pi. 5, fig. 9) writes that the species identified as Agrilus viridis variety 

 fagi Ratzeburg which makes galls on rose stems in America, is Agrilus communis aberra- 

 tion ruoicola described by Abeille de Perrin, in the Revue d'Entomol., vol. 16, 1897, p. 15, 

 and is distributed throughout the western, eastern, and southern parts of Europe.
