Buprestis sepuita. 



Buprestis .septi/ta Scudd., Rep. Prog. Geol. Snrv. Can., 1877-1878, 181b (1879); 

 Id., Tert. Ins. N.A., 495, PI. ii, fig. 26 (1890). 



A single specimen, showing the greater part of both elytra in natural 

 conjunction, must be separated from the two preceding by its still broader 

 elytra with more rapidly tapering apex. The elytra are slightly less than 

 three and a half times longer than broad, with sides parallel throughout 

 three-quarters of their length, then suddenly tapering, the extreme tip 

 shaped as in the other species, only more produced, so as to form more 

 distinctly a kind of lobe, the outer margin being very slightly and roundly 

 excised just before the produced tip. The surface is perhaps even rougher 

 than in the other species, but the strije appear to be less sinuous ; the 

 scutellar stria is destroyed in both elytra of the single specimen before 

 me ; the outer stria terminates as in B. tertiaria, but the inner pair of the 

 middle series of striie is here the longer, extending barely to the tip of the 

 outer stria, while the outer pair is a little shorter ; the produced tip of the 

 elytra is a little shorter than in the preceding species, but similarly rounded 

 apically.

Family ELATERID^. 

 LiMONius Eschscholtz. 



Limonius impunctus. 



PI. II, fig. .3. 



A long and slender elytron of moderately large size plainly belongs to 

 the Elaterid?e and seems to fall in the near vicinity of Limonius, though 

 when its complete remains are found it will be likely to prove distinct. 

 As preserved, the elytron is of a dead black or black-brown coloui", nearly 

 flat, with nearly parallel sides, and about four times as long as broad ; 

 unfortunately the tip is broken, but it would appear not to have been 

 much produced. The scutellum must have been as in Limonius. There 

 are nine stripe, or rather series of deeply impressed linear punctures, often, 

 especially in the outer series, coalescing ; the first unites with the second 

 by the middle of the basal half of the elytron, and there is some confusion
