NORTH AMERICAN BUPRESTID BEETLES 223 



sternum densely, finely granulose, with numerous small asperities, 

 and rather densely clothed with short, erect, inconspicuous hairs; 

 prosternal lobe broad, strongly declivous, and with a deep semi- 

 circular emargination in front; prosternal process broad, the sides 

 parallel to behind the coxal cavities, then obliquely narrowed to the 

 apex, which is rather acute. Tibiae slender, straight, and the an- 

 terior and middle pairs with a small tooth on the inner margin at 

 apex. Posterior tarsi slightly shorter than tibiae, and the first joint 

 as long as the following three joints united. Tarsal claws dissimilar, 

 anterior and middle ones cleft near the tip, and the teeth acute and 

 nearly equal in length ; posterior pair cleft near the middle, the inner 

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



Female. — Differs from the male in being more robust, head reddish 

 cupreous, with a violaceous tinge, front of head slightly broader, 

 about equal in width at top and bottom, the lateral margins more 

 parallel, and the surface not quite so densely pubescent; antennae 

 extending to middle of pronotum; eyes equally rounded above and 

 beneath, and the tarsal claws similar on all feet, cleft near the middle, 

 the inner tooth shorter than the outer one, and feebly turned inward, 

 but the tips widely separated. 



Length, 7.25-9.25 mm. ; width, 1.8-2.75 mm. 



Redescribed from specimens collected at Newark, N. J. 



Type locality. — Of sinuatus, France, " Provence " (an old province 

 in the southeastern part, now forming the departments of Bouches 

 du-Rhone, Basses-Alpes, and eastern part of Vaucluse) ; present loca- 

 tion of type unknown to writer. Of chryseis, England (between 

 Brockenhurst and Bottomsley, Hampshire) ; present location of type 

 unknown to writer. 



DISTRIBUTION 



Southern Europe and Algeria. In the United States : 



Connecticut: Norwalk, Stamford, Greenwich, and New Haven (W. E. Britton). 

 New Jersey : Local in Essex, Union, Middlesex, Bergen, and Monmouth counties 



(J. B. Smith and H. B. Weiss). 

 New York : Southeastern part, in 5 or 6 counties contiguous to the Hudson 



River (Parrott and Glasgow). 



Variations. — None worthy of note, except size, has been observed 

 in the specimens examined. 



Host. — In the United States the larva bores in the sapwood of cul- 

 tivated pear (Pyrus communis Linnaeus), causing serious injury and 

 requires two years to mature. It is also recorded as breeding in 

 thorn {Crataegus sp.). Chamberlin (1926) records red oak {Quercus 

 ■rubra Linnaeus), but this is probably incorrect. 



This species was first discovered in this country in 1894, at Irving- 

 ton, N. J., where it was causing serious injury to pear trees
