NORTH AMERICAN BUPRESTID BEETLES 315 



clothed with short, recumbent, whitish hairs; first abdominal seg- 

 ment slightly flattened but not conspicuously pubescent at middle; 

 prosternum densely punctate, and densely clothed with long, semi- 

 erect, whitish hairs, and the anterior and middle tibiae armed with 

 a small tooth on inner margin at apex. 



Redescribed from the female lectotype, No. 3495, in the Phila- 

 delphia Academy of Natural Sciences. 



Type locality. — Western Nevada. 



DISTRIBUTION 



Material examined: 



Abizona: Palmerlee ( ). Huachuca Mountains, July 15-28 (J. S. Hine) 



(H. A. Wenzel). Carr Canyon, Huachuca Mountains, August, 1895 (H. 

 Skinner). Santa Rita Mountains, 5,000-8,000 feet, July (F. H. Snow). 



Nevada: No definite locality (Morrison). 



Variations. — Scarcely any variation was observed in the specimens 

 examined, except in size, and the prosternal lobe, which is either 

 broadly rounded, broadly subtruncate, or feebly emarginate in front. 

 Length, 3 to 5.25 millimeters. 



Host. — Unknown. 



This species is closely allied to imbelUs Crotch and sierras Van 

 Dyke. From the former the males can be separated by the first and 

 second abdominal segments being longitudinally concave at the mid- 

 dle, and densely clothed with long pubescence, whereas in imbellis the 

 first and second abdominal segments are feebly flattened at the 

 middle, and not clothed with conspicuous hairs. There will be some 

 difficulty in separating the females of these two species, but in 

 abditus the pronotum is usually more longitudinally depressed, and 

 the prehumeral carinae atfe sharply elevated. From sierrae it can 

 be separated by not having the front of the head deeply depressed, 

 and the marginal and submarginal carinae of the pronotum not 

 separated from each other for their entire length. 



111. AGRILUS PUBESCENS, new species 



Male. — Form small, moderately elongate, slightly flattened above, 

 and strongly shining; head reddish cupreous in front, and becoming 

 piceous on the occiput ; pronotum and elytra piceous, with a more or 

 less cupreous tinge; beneath reddish cupreous, and more shining 

 than above. 



Head with the front broad, nearly flat, about equal in width at 

 bottom and top, broadly, arcuately constricted at middle, and without 

 a distinct median depression ; surface densely, finely granulose, finely 

 punctate, more or less longitudinally rugose on the occiput, and 

 rather densely clothed with semierect, white hairs; epistoma slightly
