specimens of regularis, but give here a description of the vari- 

 ations from the typical form of only 10. The specimens are 

 numbered consecutively, and are otherwise typical. 



1. Right elytron with six interruptions on the 8th interval. 



2. Right elytron with five interruptions on 4th interval and 

 six on 8th ; left with seven on 8th and two on gth. 



3. Right elytron with gth stria interrupted, left with i2th 

 interval but once. 



4. Punctures on 4th and 8th intervals very faint. 



5. Right elytron having yth and 9th intervals interrupted 

 once, left having 4th and 5th striae run together and confused. 



6. Right elytron having 4th and 8th intervals with very 

 faint indication of interruptions, left having 4th interval not 

 entirely interrupted in any one place and 8th with only faint 

 indication. 



7. L/eft elytron without interruption on 4th interval ; striae 

 on both el3 r tra toward the margins confused. 



8. Left elytron with eight interruptions on 8th interval ; 

 right with seven on 4th, and eight on 8th ; 6th interval wavy 

 and punctured. 



9. Right elytron with five interruptions on 4th interval, 

 seven on 8th, and four on nth, 9th and loth run together in 

 some places ; left' with six on 4th, and having striae somewhat 

 confused toward the margin and posteriorly. 



10. Right elytron with six interruptions on 4th interval, 

 seven on 8th, and three on i ith ; left with six on 4th, eight on 

 8th, and one on nth. 



Also, the Spokane specimens of relict us show some tendency 

 toward regular striation on the elytra, two or three striae on 

 one or two specimens being moderately straight. 



One specimen from Cedar Mountain shows the characters of 

 both species to such an extent that it is impossible to say defi- 

 nitely whether it is relict its or regular is. 



This shows quite clearly that the differences between relict us 

 and regularis are not so constant as the types seemed to show. 



It appears to me, after making an extended examination, 

 that in extreme regularis the interspaces between the striae 

 have their sides perfectly smooth and straight, and that in UK
