NORTH AMERICAN BUPRESTID BEETLES 257 



the carina not projecting. Prosternum finely, densely punctate, and 

 densely clothed with long, recumbent, whitish hairs; prosternal lobe 

 broad, moderately declivous, and broadly subtruncate in front ; pros- 

 ternal process broad, the sides vaguely expanded behind the coxal 

 cavities, then abruptly narrowed to the apex, which is acute. Tibiae 

 slender, anterior and middle pairs vaguely arcuate, and without a 

 tooth at apex. Posterior tarsi slightly shorter than tibiae, and the 

 first joint as long as the following two joints united. Tarsal claws 

 similar on all feet, cleft near the middle, the inner tooth slightly 

 shorter than outer one, and not turned inward. 



Length, 5.5 mm. ; width, 1.38 mm. 



Male. — Differs from the female in having the front of head slightly 

 more greenish and narrower; antennae extending nearly to middle 

 of pronotum; first abdominal segment vaguely flattened at middle; 

 pubescence on prosternum slightly more erect; anterior and middle 

 tibiae armed with a short tooth on inner margin at apex, the -tarsal 

 claws cleft closer to tip, and the teeth nearly equal in length. 



Redescribed from the female lectotype No. 3493 in the Philadelphia 

 Academy of Natural Sciences. 



Type locality. — Arizona, probably near Tucson. 



DISTRIBUTION 



Material examined : 



Arizona: Nogales, Aug. 12, 1906 (F. W. Nunenmacher). Ashfork, June 17-24 

 (Barber and Scnwarz). Catalina Springs, May 5, reared (Hubbard and 

 Schwarz). Baboquivaria Mountains (F. H. Snow). 



Also recorded from the following localities, but some of these 

 records may not be this species : 



Arizona : Prescott ; Pboenix ; Tucson ; Huachuca Mountains. 

 Colorado: Glenwood Springs. 

 Lower California : San Julio. 

 Utah : St. George. 



Variations. — Very little variation was observed in the specimens 

 examined except in color and size, the color varying from reddish 

 cupreous to bronzy green, and the length from 4.5 to 6 millimeters. 

 In some of the specimens the front of the head is more deeply 

 depressed than in others, and the rugae on the pronotum are coarser 

 and more widely separated. 



Host. — This species has been reared from " Palo Verde " (Parkin- 

 sonia microphylla Torrey) in Arizona by Hubbard and Schwarz. 



This species is very closely allied to jacobinus Horn, but can be 

 separated from that species by having the sides of the pronotum 

 clothed with distinct long hairs, and with a distinct pubescent vitta 

 on each elytron, whereas in jacobinus the sides of the pronotum are
