Ancylocheira. They seem to be nearly related also to the Tertiary species 

 from Sieblos, described by Heyden under the name of B. senecta. For 

 the present I place them in Buprestis. 



The elytra are very long and slender, nearly four times as long as broad, 

 equal throughout the basal two-thirds, then gradually and very regularly 

 tapering by the sloping of the outer edge, the tip a little produced and 

 rounded, and about one-fourth as broad as the middle of the elytron. The 

 surface is ornamented by ten rows of very distinct striae with rather 

 deeply impressed puncta ; these strise are a little sinuous near the base, 

 and there is also a scutellar stria extending down nearly one-third of the 

 elytron ; the outer stria unites with the margin in the middle of the 

 outer half of the elytron ; the three inner and two other outer striae 

 extend to the apex, while the four interior strise terminate : the inner 

 pair a little beyond the termination of the outer stria, the outer pair still 

 a little farther toward the apex, thus allowing for the narrowing of the 

 elytra; the surface between the strise is much broken by slight transverse 

 corrugations, giving, with the punctate strife, a rough appearance to the 

 elytra. This species differs from the two following by the great slender- 

 ness of the elytra and the more delicate tapering of ijs tip.

Buprestis saxigena. 



Buprestis saxigena Scvirn., Rep. Prog. Geol. Surv. Can., 1877-78, 181 B (1879); 

 Id.. Tert. Ins. N". A., 494-495, pi. ii, figs. 24, 25 (1890). 



This species is represented by several elytra or fragments of elytra, 

 sometimes preserved by pairs in natural connection. It is very closely 

 allied to the last, but differs from it in having the elytra less slender, the 

 breadth being contained about three and a half times in the length, and in 

 the rather greater coarseness of the punctuation and transverse corru- 

 gation. The strise are the same in number, but are, perhaps, a little more 

 sinuous, and the scutellar stria is shorter, hardly extending so much as a 

 quarter-way down the inner margin ; the outer strise terminate in much 

 the same way as in B. tertiaria, but the seventh stria (from the suture) 

 frequently runs to, or very nearly to, the tip ; the extreme tip is formed 

 precisely as in B. tertiaria, but the sides of the elytra, running parallel 

 throughout three-quarters of their length, taper toward the apex more 

 abruptly than in the preceding species, though with the same regularity. 

 This species stands midway between the other two here described in the 

 form of the apical third of the elytra.
