and the sublateral impression and basal callus more pronounced; 

 elytra distinctly less than twice as long as wide, much wider than the 

 prothorax, the apex more acute than in either of the preceding, the 

 sculpture similar; under surface with the sublateral areas of fine dense 

 punctures smaller and more irregular among the smooth patches, and 

 with the whitish pubescence much denser and more conspicuous, as 

 usual decumbent but having also longer and more erect sparse hairs 

 intermingled. Length (9) 21.0 mm.; width 7.7 mm. Canada (east- 

 ern Ontario). [=Buprestis liberta Germ., and borealis Lap. -Gory]. 



liberta Germ. 

 13 — Form somewhat as in liber ia but narrower and more convex, the 

 depressions duller cupreous-red, the elevations black, the under sur- 

 face bright cupreous; head scarcely more than half as wide as the pro- 

 thorax, less coarsely and more densely cupreo-punctate than in liberta, 

 with narrower rugae, the sulcus similar; antennae ( $ ) less stout, the 

 subapical joints much longer than wide ; prothorax similarly transverse, 

 relatively still smaller, the sides parallel and obsoletely bisinuate, 

 gradually strongly rounding and convergent from near the middle to 

 the apex; sculpture nearly similar; elytra nearly similar throughout 

 but still notably wider than the prothorax, the sides before the middle 

 more deeply sinuous, the depressions similarly finely, densely punctate 

 and nearly even; under surface with similarly isolated patches of dense 

 fine punctures, which however are only feebly and very inconspicuously 

 pubescent. Length ( $ ) i8.o mm.; width 6.8 mm. New York (north- 

 ern) parviceps n. sp. 



It will be observed that in the above statement some ten American 

 species are considered valid, together with several subspecies, while, in 

 the general catalogue of the Buprestidae, Captain Kerremans has 

 listed only three, since fulleri belongs to Texania and not to Chal- 

 cophora. This considerable increase of species, so material in fact 

 that it may be criticized as unwarranted, is due principally to two 

 causes: first to the fact that a number of species, long established, 

 have been hastily and erroneously suppressed in the catalogue men- 

 tioned, angulicollis and oregonensis, for example, having the elytra 

 proportionally much more elongate than virginiensis and without 

 the sutural spine of that species, being abundantly distinct and not 

 synonyms as there enrolled. Then again a number of forms have 

 been discovered since the genus was investigated by LeConte about 

 fifty years ago, so that it is believed the actual increase of synonymy 

 will at least not prove burdensome. 



The prothorax in Chalcophora is generally more prominent or 

 subangulate at the sides before the middle in the female than in the 

 male, as plainly observable in a series of virginiensis before me, in
