From Owen's Valley (F. Bischoff). This is a most variable species in 

 both color and size. Specimens measure from 4 to 7 A millimeters in length, 

 by 3 to 5 millimeters in width. The orange band across the pronotum 

 sometimes invades almost two-thirds of its surface posteriorly, and the 

 black color is replaced by pale dirty rufous.

Plate XL1I, Fig. 11. 



Ovate, polished, bright grass-green above, tolerably coarsely, deeply, 

 and here and there confidently punctured between transverse, wavy rugae ; 

 beneath very finely, remotely punctured, excepting on the disks of the pleural 

 pieces, which are more coarsely punctured. Head' as long as the pronotum, 

 triangularly rounded in front, transversely rugulose ; the lateral margins 

 whitish, and more finely and less closely punctured than the vertex ; tylus 

 smooth, very remotely punctured, the tip piceous ; antenna?, — basal joint and 

 basal half of second joint green, the apical half of second and the remain- 

 ing joints piceous, pubescent ; the second joint longest, the third not more 

 than one-half the second, the fourth and fifth shorter, subequal. Rostrum 

 reaching to the base of the third ventral segment, green, with the base, the 

 middle line and the apical joint piceous, second joint very long, reaching 

 from the base of the head to the middle coxa?, the apical joint shortest. 

 Pronotum flattened, but with a slightly convex slant forward and sideways ; 

 the lateral margins broadly whitish, bowed ; the anterior angles truncated, 

 to fit against the eyes ; the posterior angles broadly rounded ; the anterior 

 margin broadly sinuated ; the posterior margin straight, but sinuated each
