NORTH AMERICAN BUPRESTID BEETLES 3 



Teres Harris, New England Farmer, vol. 8, ser. 1, 1829, No. 1, pp. 2-3. 



Engyaulus Waterhouse, Biol. Centr.-Amer., Coleopt., vol. 3, pt. 1, 1889, 

 pp. 50-51. pi. 4, fig. 9 (includes — 1. Agrilus pulchellus Bland: 2. Engy- 

 aulus rubrovittatus Waterhouse). — Leng, Cat. Coleopt., 1920, p. 183.— 

 Chamberlin, Cat. Buprestidae, 1926, pp. 200-201 (designates Agrilus 

 pulchellus Bland as the genotype). 



The biliography given above is not complete for the genus, as 

 only the more important articles are cited, and especially those that 

 refer to the American species. The name Agrilus was first estab- 

 lished by Megerle and has been credited to him by many of the early 

 entomologists, including Dejean, but he is not recognized by the later 

 writers. Megerle published three papers between the years 1801 

 and 1812, and it is just possible that he used Agrilus in one of these 

 publications in such a manner as to validate the name, but since none 

 of these publications are available to the writer this reference could 

 not be verified. Teres was erected as a subgenus of Buprestis by 

 Harris (1829), and included (1) Buprestis granulata Say; (2) B. 

 ruftcollis Fabricius; (3) B. innuba Fabricius, etc., but Agrilus Curtis 

 (1825) has priority by a few years. 



In the above papers by Melsheimer (1853), Lacordaire (1857), 

 LeConte (1863), Gemminger and Harold (1869), Saunders (1871), 

 Crotch (1873), Austin (1880), Henshaw (1885, 1895), Kerremans 

 (1892, 1903), Leng (1920), and Leng and Mutchler (1927), many 

 American species of Agrilus are listed, but since these publications 

 are only catalogues the citations are omitted from the bibliography 

 under the species. 



DESCRIPTION OF THE GENUS 



Head vertical and grooved, flat, tuberculate, or simply convex 

 in front ; epistoma emarginate in front and narrowed by the antennal 

 cavities; cheeks unarmed or with an obtuse tooth on each side; 

 antennal cavities rather large, oblique, prolonged into a groove in 

 front, and situated at some distance from the eyes. Antennae vari- 

 able in length, serrate from the fourth or fifth joints, and not 

 inserted in a groove in the prosternum while in repose; first joint 

 elongate and robust; second, third, and sometimes the fourth, short 

 and feebly clavate, and the following joints more or less triangular, 

 serrate on the inner side, and with a terminal poriferous fovea. 

 Eyes large and oblong. Pronotum usually wider than long, rather 

 convex, and broadly sinuate in front; sides more or less arcuately 

 rounded, and with two distinct margins; base sinuate, with a broad, 

 median lobe, which is truncate, rounded, or emarginate in front of 

 scutellum; surface with or without depressions, and usually with a 

 distinct carina near posterior angles. Scutellum broad, acute poste- 

 riorly, and sometimes transversely carinate. Elytra elongate, sinu-
