Family SCARAB^ID^. 

 Trox Fabricius. 

 Trox oiistaleti. 



Trox ousfahti Scudd., Rep. Prog. Geol. Surv. Can., 1877-78, 179-180 r. (187!)); 

 Id., Tert. Ins. N. A., 487, pi. ii, fig. 22 (1890). 



A single elytron, well preserved, appears to represent a species of Trox 

 of about the size of T. terrestris Say, but with rather slender elytra. The 

 elytron is subequal, narrowing rapidly and regularly at the tip, well arched, 

 and was apparently still more arched originally, the middle portion having 

 a flattened appearance, as if from pressure, with a narrow flattened outer 

 margin ; the svirface is completely and uniformly covered with thirteen or 

 fourteen equal equidistant rows of frequent dull tubercles, as distant 

 from one another in the rows as each row from its neighbour, and obsoles- 

 cent toward the apex and the base, especially towards the former. In 

 certain places there is a very slight appearance of greater prominence to 

 every fourth row, which would hardly be noticed if its resemblance to 

 modern species of Trox did not lead one to look for it ; the extreme tip 

 is broken. The colour is dark brown, approaching black, but the .whole 

 central portion of a faded brown, nearly resembling the natural colour of 

 the stone in which it is preserved. 



Length of elytron, 4-25""'^; breadth, 1-85™". 



Named after M. Emile Oustalet, of the Jardin des Plantes, whose 

 researches on the Tertiary insects of Auvergne and Aix are well known. 



Nine-Mile Creek, British Columbia. One specimen, No. 61 — Dr. G. M. 

 Dawson. 



Family BUPRESTID^. 

 BuPRESTis Linne. 

 Buprestis tertiaria. 



Bupresfis fertiariaScvBJ)., Rep. Prog. Geol. Surv. Can., 1877-78, 180-181 b (1879) ; 

 Id., Tert. Ins. N.A., 49.3-494, pi. ri, fig. 28 (1890). 



Three specimens were obtained of this species, all of them elytra. One 

 shows the two elytra crossed at the base, and a revei-se of this shows the 

 cast of the upper surface ; the other two are single and perfect elytra, 

 both exhibiting the upper surface, one in relief, the other as a cast, but 

 they are not reverses. This and the two following species classed under 

 Buprestis agree closely together, but do not seem to be plainly referable 

 to any recent American genus, although approaching nearest Buprestis or
