L. Lateral thoracic bands linear, their 

 breadth less than .75 mm.; inner 

 margin of superior appendages in 

 dorsal view very gently sinuate, in 

 profile straight or slightly convex 

 before the middle, the inferior 

 carina rather low, its angle 

 rounded or obsolete ; breadth of 

 appendage at middle scarcely 

 twice that at the extreme base, 

 thence narrowing gradually to the 

 rounded or bluntly angulate 

 apices, which do not normally 

 bear a terminal tooth ; superior 

 carina but little elevated, finely 

 denticulated or smooth ; inferior 

 appendage three-fifths to two- 

 thirds as long as the

LL. Lateral thoracic bands about i 

 mm. broad near the lower 

 end, somewhat narrowed at the 

 middle ; inner margin of superior 

 appendages in profile slightly con- 

 ' cave before the middle, in dorsal 

 view strongly sinuate, the breadth 

 of the appendage increasing 

 rapidly from the basal fourth, so 

 that at the middle it is fully twice 

 as broad as at base, thence scarcely 

 narrowing to the well-rounded 

 apices, which bear near the outer 

 margin a prominent tooth ; inferior 

 appendage slightly more than half 

 as long as the 

 superiors. . . 10. nevadensis^ n. sp.
