10. Elytra scarcely more than twice as long as wide, with the white lateral 



margin ( 9 ) about twice as wide as in the other three species, and 

 one-fifth as wide as the elytron ; third antennal joint two-thirds as 

 long as the fourth ; hypomera with same large scattered white 

 scales in addition to the bluish or olivaceous squamules of the 

 general surface ; male much smaller, with the intervals alternating 

 in width. Length 29.0-35.0 mm.; width 8.S-ii,o mm. Arizona 



(B. Wms. Fork) simuians, n. sp. 



Elytra very distinctly more than twice as long as wide, the pale lateral 

 margin very narrow, even in the female, where it is usually a little 

 wider than in the male ; hypomera without white scales 11 



11. Sides of the elytra strongly converging from the base to the narrowly 



rounded apex, and feebly arcuate ; yellowish-white lateral vittse 

 of the pronotum extending to the lateral bead at apex ; last 

 abdominal segment ( 9 ) much less than twice as wide as long, the 

 sides only moderately oblique. Length 39.0 mm.; width 12.4 mm. 



Arizona (near Fort Apache) acuminaius, n. sp. 



Sides of the elytra very feebly converging and slightly arcuate to near 

 apical fourth or fifth, then more strongly arcuate and converging to 

 the apex ; marginal vitta^ of the pronotum flexed inward from the 

 beaded edge toward apex ; last abdominal segment ( ? ) strongly 

 oblique at the sides, fully twice as wide as long 12 



12. Scutellum wider than long; pronotum strongly, irregularly foveate 



anteriorly and laterally as in acuminaius, the sides rather abruptly 

 converging and rounded in apical third, parallel thence to the 

 acute but virtually unreflexed basal angles ; marginal vittw pure 

 white. Length 38.0 mm.; width 12.0 mm. Arizona (near Fort 



Apache) Apacheanus, Csy. 



Scutellum longer than wide ; pronotum more finely sculptured, the 

 sides broadly arcuate and converging from the middle to the apex, 

 very feebly diverging posteriorly to the slightly and very gradually 

 everted basal angles ; side vittas pale straw-yellow. Length 42.0

iT^. Body parallel, only moderately convex, the elytra arcuately narrowed 

 toward tip, the prothorax rounded at the sides anteriorly, with the 

 lateral vittee brownish, nearly half as wide as the broad dark space 

 and almost even ; minute squamules olivaceous, the under surface
