STUDIES IN THE AMERICAN BUPRESTIDiE 85 



it cannot be identical with Texania, although seemingly a valid genus 

 and not a subgenus of Chalcophora. 



The species known to me are not very numerous and may be dis- 

 tinguished as follows: — 



Species of smaller size and narrower form, the pronotal sulcus narrow and 

 deep, the serration of the elytral margins posteriorly very strong and 

 conspicuous 2 



Species of large size, broader and more depressed form, the pronotal sulcus 

 broad and shallow, the elytral serration much feebler 3 



2 — Body narrow, elongate, moderately convex, shining, with feeble obscure 

 greenish lustre, nearly glabrous, the under surface brighter cupreous 

 and with stiff, sparse and inconspicuous decumbent hairs; head rather 

 small, the front nearly flat, coarsely and confusedly punctate and rugose, 

 the median line finely grooved, with a small oval pit between the pos- 

 terior parts of the eyes, the latter moderately prominent; antennae not 

 attaining the thoracic base in either ses ; prothorax trapezoidal, from a 

 little less (d^) to somewhat more (9) than one-half wider than long, 

 the sides sensibly converging and feebly, subevenly arcuate throughout, 

 the basal angles slightly everted, acute and prominent; surface with the 

 sulcus entire, deep and acutely excavated, confusedly punctured and 

 rugose broadly toward the sides, with a deep sublateral impression be- 

 hind the middle, the basal margin very feebly sinuate at the scutellum, 

 the latter very small, rounded; elytra slightly wider than the prothorax, 

 a little more than twice as long as wide, parallel, the sides gradually 

 rounding and converging behind in more than apical two-fifths, the 

 conjoined apex feebly emarginate at the suture, the apices very narrowly 

 sinuato-truncate; surface coarsely, feebly, unevenly punctato-rugose, 

 with obscure longitudinal striae between the pronounced nervures* 

 the areolae finely but sparsely punctate and shining; sterna and first 

 ventral throughout deeply impressed (d^) or flattened to feebly con- 

 cave (9), the last ventral in the former with a large equilatero-tri- 

 angular emargination, the under surface of the last dorsal appearing 

 beyond the incisure, flat, densely punctate, puberulent and with a 

 finely and strongly beaded free edge; legs and coxae nearly as in Chal- 

 cophora. Length 22.0-24.0 mm.; width 6.7-7.8 mm. Missouri, 

 Kentucky and Indiana. [ = Buprestis campestris Say and substri- 

 gosa Lap.-Gory] campestris Say 



Body slightly broader, similarly convex, rather less shining, greenish in 

 lustre, with short hairs particularly evident posteriorly, the under sur- 

 face cupreous, with brilliant green reflection along the median parts 

 of the sterna, the pubescence more evident than in campestris, the 

 punctures laterally, as in that species, small and subevenly distributed, 

 not in dense patches as in Chalcophora; head slightly larger but other- 

 wise nearly as in campestris, though more evidently and broadly con- 

 cave toward the median line throughout; prothorax more transverse, 

 the sides nearly parallel for three-fifths from the base, there broadly
